What should you do if you need repairs or parts under Warranty?

How to get parts and or repairs done under warranty:

Notify YOUR DEALER immediately when you discover a faulty material, workmanship, or

faulty component. Do not wait weeks or months to get it reported. Be sure to tell the dealer

that this is a failure that occurred under warranty.

NOTE: Warranty work must be done by a Finn Authorized Dealer in order to be covered

by the Finn Warranty Program, unless otherwise approved by the Finn Warranty

Administrator.

Instructions to Dealer on processing warranty work:

Initiating a claim

1. Be sure to have the model, serial number and number of hours on unit.

2. A description of the problem as understood at the time.

3. Call Finn’s Warranty Administrator to secure warranty claim authorization number.

4. Conﬁ rm with Warranty Administrator that the unit is eligible for warranty coverage.

5. Any parts needed for the repair work should be placed with the Warranty Administrator

instead of the parts department. These will be shipped to you at no charge pending the

outcome of the investigation.

6. Labor hours must coincide with the published “Labor Schedule” or estimate approved

by the Finn Warranty Administrator.

7. Once work is done, a Finn Warranty Claim Form must be ﬁ lled out and emailed along

with any related receipts or invoices to the Warranty Administrator. We ask that this is

done ASAP after work is completed.

Faulty or failed parts:

IF Finn wants you to return failed parts, you will receive a return shipping label in the

package with new parts. On that Label will be marked a return authorization number. (Which

is the same number as you claim number.)

Please also mark the outside of the package that you are shipping back (using a marker)

with the claim / return number. THESE PARTS MUST BE RETURNED WITHIN 10 DAYS!

Failure to do so can void warranty coverage.

NOTE: Further information and related forms can be found on the Finn Web site in the

Dealer Portal warranty section.

ACTIVATE YOUR FINN EQUIPMENT WARRANTY

It is the responsibility of the Finn Dealer to register your Finn Equipment shortly after the

equipment start-up and operation overview at which time you will be asked to sign off on

the WARRANTY VALIDATION FORM.

Be sure to conﬁ rm with your sales representative that this has been done.

This registration process activates the Finn Limited Warranty.

gles when operating

or feeding the machine.

Other safety attire, such

as safety shoes, ear pro-

tection, gloves, hard hats,

dust masks, etc., should

be worn as required

by warning decals on

machine, operator’s manuals, or job site require-

ments. Remove rings, watches, etc. Avoid wearing

loose-fitting clothing that may get caught in rotating

machinery.

2. Do not override or tamper with the safety-shutdown

switches on the folding door or discharge. If switch-

es fail, use OSHA lockout/tagout procedure (29 CFR

1910.147) until switches are repaired or replaced.

3. Do not operate the machine

without all guards in place.

4. Never attempt to connect, or disconnect the dis-

charge hose while the engine is running.

5. Make sure that no one

is working in or on the

condition and mentally alert to operate this machine.

BARK BLOWER SAFETY SUMMARY SECTION

It is important that all operators of this machine are familiar with all the safety aspects mentioned

below before operating the machine. Always keep a copy of this manual with the machine. It is the respon-

sibility of the operator of the machine to fully understand this safety section. Remember that YOU are the

key to safety. Good safety practices protect not only you but also the people working with and around you.

Keep in mind that this safety sheet is written for this type of machine only. Practice all other usual and

customary safe working precautions; and above all, remember that safety is up to you.

3

10. Never modify the machine. Never remove any part

of the machine (except for service and then reinstall

before operating).

11. During application through a hose, high pressure

can be exerted at the end of the hose. Hose-holding

personnel must establish good footing. The operator

should apply gradual pressure to the hose only after

hose-holding personnel are firmly positioned and

have firm control of the hose. Additional personnel to

direct hose may be necessary if working on slopes.

The proper technique for grasping the hose used by

hose-holding personnel is to route and firmly grasp

the hose over the shoulder or under both arms.

Never route/hold the hose so it goes between the

legs. If the hose-holding personnel finds that it is

uncomfortable for him to handle the hose by himself,

additional hose holders should be positioned at the

end of the hose.

12. The blower discharges material at pressures and

velocities that can cause severe bodily injury. Do not

aim discharge at people, animals, etc. Only aim the

discharge at the intended discharge area. Unless

properly protected, do not place hand into the dis-

charge stream.

13. Do not open any doors

or access panels while

machine is in operation.

Severe injury may result

from rotating parts.

14. Do not attempt to pull any-

thing out of the blower

hopper while machine is

in operation. Shut down

the engine using the

OSHA lockout/tagout pro-

cedure (29 CFR 1910.147)

before removing any for-

eign objects. Signal visu-

ally or audibly that all is

clear before operating the

machine.

15. When leaving the blower unattended for any reason,

be sure to:

A. Shut off conveyor drive.

B. Shut off vehicle engine and blower engine.

C. Place transmission of the vehicle in NEUTRAL

or PARK.

D. Set parking brake firmly.

E. Lock ignition and take keys with you.

F. Lock vehicle cab.

G. If parked on a steep grade, block the wheels.

These actions are recommended to avoid unauthor-

ized use, runaway, vandalism, theft, and unexpected

operation when the equipment is restarted.

16. Do not read, eat or otherwise lose or lessen your

attention in any manner while operating the blower.

Operating the equipment is a full-time job.

17. Be careful when getting on

and off the blower, espe-

cially in wet, icy, snowy, or

muddy conditions. Clean

mud, snow, or ice from

steps, fenders, and foot-

wear.

18. All personnel operating and/or around the machine

must be aware that the blower can be controlled via

remote control. For safety reasons and to prevent

accidental starting, always keep the power switch

on the remote receiver in the OFF position when the

remote control is not being used.

19. Be careful when operating the tarp near power lines.

Raising the tarp into power lines may cause severe

electrical shock. Always have the tarp either fully

open or retracted when transporting the machine.

20. Turn slowly and travel carefully on rough surfaces

and side slopes, especially with a loaded blower

body.

III. MAINTENANCE:

1. Before servicing the

machine, turn off engine

and allow all moving parts

to stop. To prevent acciden-

tal starting, disconnect bat-

tery cables. Tag the engine

operating area to show that

the machine is being ser-

viced. Use lockout/tagout

procedure (OSHA 29 CFR 1910.147).

2. Take extreme care when

adjusting or replacing

knives. Knife edges are

very sharp and can cause

severe bodily injury.

3. Radiator maintenance: Liquid cooling systems build

up pressure as the engine gets hot. Before remov-

ing radiator cap, stop the engine and let the system

cool. Remove radiator cap only after the coolant is

cool. Mulch may accumulate in the radiator fins after

extended usage based upon mulch properties. The

radiator should be inspected prior to daily start-up

and cleaned by pressure washing if obstruction is

present.

4. Battery maintenance: Lead-acid batteries contain

sulfuric acid, which will damage eyes or skin on con-

tact. Always wear a face shield to avoid getting acid

in the eyes. If acid contacts the eyes, flush imme-

diately with clean water and get medical attention.

Wear rubber gloves and protective clothing to keep

acid off skin. Lead-acid batteries produce flammable

and explosive gasses. Keep arcs, sparks, flames,

and lighted tobacco away.

5. Filling of fuel: Never fill the tank with the engine run-

ning, while smoking, or when near an open flame.

Never smoke while handling fuel or working on the

fuel system. The fumes in an empty fuel container

are explosive. Never cut or weld on fuel lines, tanks

or containers. Move at least 10 ft (3 m) away from

fueling point before starting engine. Wipe off any

spilled fuel and let dry before starting engine.

IMPORTANT: Be careful not to allow fuel, lubricant,

hydraulic fluid, or cooling fluids to penetrate into

the ground or be discharged into the water system.

Collect all fluids and dispose of them properly.

6. It is recommended that only authorized, genuine

FINN replacement parts be used on the machine.

7. Do not use either cold start fluid, if engine is

equipped with glow plug type preheater, or other

intake manifold-type preheater. It could cause an

explosion or fire and severe injury or death.

8. Diesel fuel or hydraulic fluid

under pressure can pen-

etrate the skin or eyes and

cause injury, blindness, or

death. To check for such

leaks, use a piece of card-

board or wood instead of

your hand. Pressure may

build up in the hydraulic

system; use caution when removing the cap.

9. Some parts and assemblies are quite heavy. Before

attempting to unfasten any heavy part or assembly,

arrange to support it by means of a hoist by blocking

or by use of an adequate arrangement to prevent

it from falling, tipping, swinging, or moving in any

manner. Failure to do so could result in component

damage, or physical injury to someone.

10. If repairs require use of a torch or electric welder, be

sure that all flammable and combustible materials

are removed. Fuel or oil reservoirs must be emptied,

steam-cleaned, and filled with clean water before

any cutting or welding on them is attempted. Do

NOT weld or cut on any tank containing oil, gasoline,

fumes, other flammable material, or on any container

of which the previous contents were unknown.

11. Do not pressure wash this unit.

Do not pressure wash around any

control boxes, radio remotes or

control panels. Pressure washing

this unit can cause damage to the

electrical systems and components

and also cause the unit to not

function. Pressure washing injects water into

sensitive electrical components. To clean the unit,

use a method that controls the amount of water that

is applied to the surface of the unit.

5

P/N 13184

Wear ear protection when

operating machine.

The sound power level could

exceed 80 dB(A) while the unit

is in operation.

Failure to comply could result

in moderate or minor injury.

OPERATION AND MAINTENANCE

MANUAL FOR

FINN BARK BLOWER

INTRODUCTION

The FINN Corporation would like to thank you for your latest FINN purchase. In our efforts to

maintain a quality and growing relationship with every customer, we would like to encourage you

to contact us for help with service, genuine replacement parts, or for any other information you

may require.

THE FINN BARK BLOWER AND ITS FUNCTION

The FINN Bark Blower is an apparatus for conveying and discharging bulk materials, such as bark

mulch, at a fast and uniform rate while utilizing a minimum amount of manpower. The product to

be used is generally composted and processed, then, used as a soil amendment, ground cover for

erosion, weed control, or for decorative purposes on landscaping (bark mulch).

This manual is intended to provide step-by-step instructions on the operation, care, and main-

tenance of the Bark Blower. In addition, it contains illustrations and a complete list of parts and

components for easy identification.

HOW THE BARK BLOWER WORKS

The bulk material is loaded into the hopper by a loader or by an infeed elevator. Located at the

bottom of the hopper is a drag conveyor, which conveys the bulk material to an opening contain-

ing a feed roll. The feed roll and drag conveyor feed the bulk material into an airlock. The airlock

is specifically designed and built to handle tough, fibrous material. The function of the airlock is

to take the bulk material into open pockets exposed to the outside air, and to convey it to an area

where the pocket is closed off. At that point, a high-pressure air stream, created by the blower, is

channeled through the pocket, carrying the material through the hose for discharge.

NOTICE

For best results and to ensure safe operation and long life of the equipment, please read and fol-

low all instructions carefully.

MOUNTING THE BARK BLOWER

The selection process of the vehicle onto which a blower is to be mounted has important safety

aspects to avoid overloading:

A. Do not mount a blower onto a chassis which, when fully loaded with material, will exceed

either the Gross Axle Weight Rating (GAWR) or the Gross Vehicle Weight Rating (GVWR)

for the chassis. See below.

B. Do install the blower only onto a vehicle with cab-to-axle dimension recommended for the

blower-body length selected. See below.

Once the proper carrier has been selected, the blower must be securely mounted onto it.

CAUTION

The FINN Bark Blower should be mounted by a qualified truck body installer. Failure to

comply could result in minor to moderate personal injury. Failure to comply could also

result in product or property damage.

NOTICE

The mounting of the blower to the truck must allow for tire clearance, as well as frame twist.

Place hard-wood spacers along the length of truck rails or use FINN Spring Mounting Kit (number

011562) or equivalent.

Follow mounting instructions given in Figure 1 and Figure 2 on Page 8. If mounting conditions

require deviation from these instructions, consult the factory.

SELECTING A MULCHING MATERIAL

Several factors must be considered when selecting material to convey through the Bark Blower.

The variety of the wood used, how it is processed, its moisture content, and the presence of for-

eign objects all affect the ability of the Bark Blower to convey the mulch at a uniform and accept-

able rate.

The mulch material must be processed and/or screened, so that a minimum of material is over 2

in. (5.1 cm) in any direction, with no material exceeding 4 in. (10.2 cm) in length. The Bark Blower

is not a wood processor. The Bark Blower only reduces mulch fibers when they protrude above

the airlock vanes. As the vanes rotate past the knife, the protruding fibers are sheared off. If

the mulch contains long or large fibers and the wood fibers are harder to cut, then the machine’s

throughput is reduced. For example, if two mulches have the same mix of material sizes that the

Bark Blower rotor must cut, but one is a softwood like pine and one is a hardwood such as oak,

the pine would go through at a higher rate because it is easier to cut. Two characteristics must be

considered when selecting a material: the greenness of the wood and the moisture of the mulch

as a whole. Wood that is well seasoned is easier to cut than green wood. Seasoned wood also

processes better, making a less stringy mulch. High moisture in the mulch may cause it to bridge

in the hopper.

CAUTION

Avoid using mulches that contain any hard foreign objects, such as rocks, nails, steel,

cans, glass, etc. Failure to comply could result in minor to moderate personal injury.

Failure to comply could also result in product or property damage.

PRE-START EQUIPMENT CHECK

CAUTION

Equipment check must be made with the engine OFF and all rotating parts stopped. Failure

to comply could result in minor to moderate personal injury. Failure to comply could also

result in product or property damage.

Safety check to ensure operator safety:

1. Check that all the truck mountings are secure.

2. Ensure that all guards are in place.

3. Tool Kit - make sure that it contains all prescribed items (see tool kit list Parts Man

ual).

4. Lubricate equipment. Use handgun only (see Lubrication Chart, pages 32 and 33.

5. Check engine oil and fill or change if necessary. Refer to Engine Operator’s Manual.

6. Check liquid coolant level in radiator and fill or replace if necessary (protected to

-34ºF [-37ºC] when shipped.)

7. Check fuel level. Use number 2-D diesel fuel oil, unless operating at ambient

temperature below 40ºF (4ºC) or at an altitude exceeding 5,000 ft (1,524 m). In these

instances, use number 1-D diesel fuel oil.

8. Inspect the engine air cleaner (refer to the Engine Operator’s Manual), the radia-

tor chaff screen, and the blower air cleaner for dust and dirt. If necessary, clean or

replace the air filter.

11

9. Check hopper and transition for foreign objects that could injure workers or dam-

age equipment.

10. Check the fluid level in the hydraulic tank. Make sure that the service valve is open

on reservoir. Proper level is midway between the upper and lower indicator mark

on the sight gauge. (See page 29 for oil specification.)

11. Install the discharge hose. Use the short hot-air hose section as the first connec-

tion after the airlock. This will help extend the life of the other hoses. Use the

clamps provided with the machine.

12. Check to verify the radiator is free of mulch and debris obstruction to ensure over

heating does not occur.

CAUTION

Do not use radiator-type clamps. These clamps may not hold under machine-operating

pressure. Failure to comply could result in minor to moderate personal injury. Failure to

comply could also result in product or property damage.

STARTING PROCEDURE

CAUTION

See safety section of the manual (pages 2 through 4) before operating the machine. Failure

to comply could result in minor to moderate personal injury. Failure to comply could also

result in product or property damage.

1. Place the remote control switch in the OFF position on the control panel.

2. Turn the key clockwise until starter engages and the engine starts.

NOTE: This engine has a safety system that will shut the engine off if the

engine oil pressure drops below 7 psi (48 kPa) or if the water tem-

perature reaches 230ºF (110ºC).

3. Allow engine to warm up for 3 to 5 minutes.

4. Prior to mulch application, move the throttle position to fully open, and allow the governor to

control the engine speed. Refer to page 16, Bark Blower Adjustments, for further informa-

tion on control settings. Governed engine speed should be 2,575 to 2,625 rpm under load.

CREW MEMBERS AND THEIR DUTIES

1. The Operator controls the placement of the mulch by moving and aiming the discharge

hose.

2. The Loader(s) feed material to the machine by using a bucket loader or belt conveyor,

dumping material directly into the hopper.

THE MATERIAL-FEED SYSTEM

The material-feed system on the Bark Blower has been designed to give fast and uniform mechan-

ical feeding. The adjustable feeding rate and the automatic reverse control system allow the use

of varied materials while obtaining maximum production. The system is an integration of the fol-

lowing four subsystems, all of which contribute to efficient material flow:

12

SUBSYSTEM 1: MATERIAL HANDLING GROUP

The four major components of the material handling group are the blower, the drag conveyor, the

feed roll, and the airlock.

The blower is a rotary lobe, positive-displacement-type unit having two double-lobe impellers. The

blower is directly driven off the engine flywheel via a flexible coupling. Therefore, whenever the

engine is running, air is being pumped. The blower is equipped with a relief valve, limiting maxi-

mum air pressure to 16 psi (110 kPa), an inlet and outlet silencer for noise attenuation, and an inlet

air filter.

The drag conveyor receives material from the hopper and conveys it to an opening located at

the rear of the hopper where the feed roll is located. The feed roll ensures a uniform feed of bulk

material to the airlock. The drag conveyor is powered by a variable-speed hydraulic motor, which

also powers the feed roll.

The airlock receives the material from the drag conveyor and receives pressurized air from the

blower. Its primary function is to convey the material from the atmospheric air to a sealed cham-

ber where the blower air picks it up and blows it out of the hose. To enable the Bark Blower to

convey fibrous material, the rotary-air-valve housing is equipped with a cutting knife and the vanes

on the rotor are angled and hardened. If any long material should protrude above a vane, it will

be sheared off, before the vane enters the close tolerance of the housing, by a scissor-like action

between the vane and cutting knife. The rotor of the airlock is directly coupled and driven by a bi-

rotational hydraulic motor and gearbox.

SUBSYSTEM 2: HYDRAULIC SYSTEM

Hydraulic power for the Bark Blower is generated by a flow-and-pressure-compensated, load-

sensing pump that is driven off the engine auxiliary drive. This means the pump can measure how

much load is on the hydraulic circuit and will only pump the oil needed to satisfy the demands of

the circuit. The pump receives DTE-13M hydraulic fluid from the 36gal (136L) reservoir through a

service valve and suction hose. It then delivers it to the valve manifold. The manifold is one block

of machined aluminum, equipped with valve cartridges and solenoids that control all functions of

the Bark Blower.

Two pressure gauges at the valve manifold read the valve inlet pressure. These gauges include

the left/rear gauge and the load-sense pressure (right/front gauge). The left/rear gauge should

always read about 300 psi (2,068 kPa) more than the right/front gauge. This 300 psi (2,068 kPa)

difference is called the margin pressure. The margin pressure is a measurement of the pump's

ability to respond to changes in the hydraulic circuit. If the margin pressure is set too high (over

500 psi [3,447 kPa]), the pump will be too sensitive and can become unstable. If the marging

pressure is too low (below 200 psi [1,379 kPa]), the pump can become sluggish and not provide

enough oil flow for the demand. The margin pressure can be adjusted using the lower compensa-

tor-adjustment screw in line with the load-sense hose on the back of the hydraulic pump. The only

time the gauges will not show the margin pressure is when one of the hydraulic circuits has stalled,

as if the floor conveyor somehow became jammed. In this case, both gauges will show the high-

pressure standby of 2,800 psi (19,305 kPa) until the blockage is removed. High-pressure standby

is the maximum pressure the pump will produce. A system relief valve is set for 3,500 psi (24,132

kPa) to protect the system if there is a failure in the pump compensator.

DESCRIPTION OF VALVE SECTIONS

Figure 3 shows the valve block and the different hydraulic circuits. Each circuit, except for the Hose

Reel (HR) circuit, is controlled by two valves. On the Floor (F) and Airlock (AL) circuits, the flow rate

is controlled by the proportional valves. These valves can be manually stroked by inserting a small

rod or screwdriver into the hole in the bottom of the solenoid. The Floor and Airlock circuits also

have a directional valve that can be manually stroked by pressing the red knob on the bottom of the

solenoid. The Agitator (A) and Seed Injection (S) circuits are controlled by a three-position valve that

is actuated by one of two solenoids. These valves can be stroked manually by pressing or pulling

on the red knob located on the bottom of the solenoid. The Hose Reel (HR) circuit is controlled by a

two-position ON/OFF valve. Its solenoid can only be actuated in one direction by pressing on the red

knob, located on the bottom. The flow rates for the Hose Reel, Seed Injection, and Agitator circuits

are adjusted using the flow control valves. These valves are located directly behind the solenoids

for their respective circuits.

A. HOSE REEL

The left side of the manifold controls the hose reel. The flow rate is factory set, so the hose reel

winds and unwinds at a rate of about 13 rpm.

B. AGITATOR

The third valve section controls the speed and rotation of the agitator. The spool in this section is

factory set, so the agitator rotates at approximately 4 rpm. This section also has a pressure switch

installed on the forward port that is set for 2,400 psi (16,547 kPa). This pressure switch triggers the

agitator auto-reverse function. Normal rotation of the agitator is clockwise when viewing from the

rear of the machine.

C. FLOOR (DRAG CONVEYOR)/FEED ROLL

The fourth valve from the left controls the floor and feed roll speed. It is an electrically-driven pro-

portional valve that is controlled by the floor-speed settings on the control box. Adjusting the dial

from 0 to 100 varies the input voltage to the solenoid and moves the spool in the valve accordingly,

thus allowing more or less oil flow to the floor and feed roll. The feed roll is plumbed in series with

the floor, meaning that the oil flows to the feed roll motor first and then down to the floor motors.

This setup automatically causes the floor to slow down if the feed roll begins to jam up, which pre-

vents overfeeding of the feed roll.

D. AIRLOCK

The last valve section of the manifold runs the airlock. The spool in the valve is factory set, so the

airlock turns at about 12 rpm. The proportional valve in combination with the control box, provides

adjustment of the airlock speed. There is a pressure switch on the forward circuit that is set for

2,400 psi (16,547 kPa) that triggers the auto-reverse function on the airlock. Normal rotation of

the airlock is clockwise if viewing from the driver side of the machine.

SUBSYSTEM 3: HYDRAULIC CONTROL SYSTEM

The hydraulic control system is an electrical system that controls all the hydraulic functions on the

Bark Blower. This 12-VDC system runs off the engine electrical system. It is a programmable

logic control (PLC) system located in the electrical control box on the passenger-rear side of the

machine. This module controls the solenoid valves in the hydraulic system. The solenoids are

energized by way of the white DIN connectors mounted on each solenoid. The DIN connectors

each have a small red light in them that illuminates if the circuit is active. This is an easy way to

check if a particular circuit has electrical power.

When Material Start is selected from the PANEL OPERATE screen, the proportional solenoid on the

airlock valve section is energized, which starts the airlock. If the floor toggle switch is in the ON posi-

tion, the floor and feed roll solenoid is also energized after a factory-set 1.5 second delay. This delay

ensures that the airlock has a chance to clear itself. After the delay, the floor and feed roll will begin

to move at the speed relative to the Floor Speed %. This speed can be set by using the Material

Increase and Material Decrease buttons on the PANEL OPERATE screen. The default adjustments

are in 5% increments which can be changed in the USER SETTINGS screen.

As material drops into the top of the airlock, the pressure required to cut the material is monitored

by the pressure switch. This switch is located on the forward port of the airlock valve section, in the

manifold labeled AL1G (see Figure 3 on page 13). The switch is normally open. When the airlock

motor stalls due to the rotor encountering an object it cannot cut, high pressure is created in the

airlock circuit and the pressure switch closes. The amount of time the pressure switch is closed is

monitored by a setting in the PLC box. If the switch remains closed for more than 0.5 second, the

system automatically reverses the rotor by energizing the reverse solenoid. It also de-energizes the

floor solenoid, thus shutting off the floor and the feed roll. The airlock will remain in reverse for ap-

proximately 1.5 second. The system will then restart the floor and feed roll after allowing the airlock

to clear itself.

The agitator is also controlled through the PLC box. The agitator will start on a 3-second delay (in

a similar manner to the floor) and will stop during an auto-reverse. The agitator circuit on the Bark

Blower also has an auto-reverse feature for when the agitator may bog down and become unable to

turn itself. This most often occurs at the beginning of a load when the hopper is completely full of wet

or packed down mulch. The PLC system receives a signal from the pressure switch on the forward

port of the agitator circuit labelled A1G when the agitator motor stalls. When this signal is received,

the system automatically de-energizes the solenoid before the pressure switch and energizes the

reverse solenoid on the valve circuit, causing the agitator to rotate in reverse. The reverse-rotation

time is set for 10 seconds, after which the forward solenoid will energize and the agitator will return to

its normal rotation. This process may be repeated several times until the agitator sufficiently breaks

up the packed mulch material. The agitator auto-reverse process does not interrupt or affect any

other function(s) on the Bark Blower.

When the Material Stop is activated, power is shut off to solenoids controlling the hydraulic motors

on the floor, airlock, feed roll, and agitator. The hydraulics can also be stopped by turning the ignition

key OFF. Please note that the hydraulics will also stop if the folding door on the feed roll housing is

opened and cannot be restarted until they are closed and the Material Start is activated.
