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 responsibility

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.

I. PRE-START EQUIPMENT CHECK (equipment

check is to be made with the engine off):

1. Check hitch and hitch

bolts, safety chains, lights,

brakes, and breakaway

switch. Verify that the hitch

ball or pintle hook is the

correct size for the coupler.

2. Verify that all guards are in

place.

3. By carefully looking into the

blower hopper and transition, inspect for and remove

any foreign objects. Follow Occupational Safety and

Health Administration (OSHA) lockout/tagout proce-

dure (29 CFR 1910.147)

4. Inspect all hydraulic hoses and tubes for cracks,

bulges, or damage. If hose is cracked, bulging, or

damaged, replace immediately.

5. Inspect the material discharge hose and connections

for cracks or damage. If cracks or damage is found,

replace affected part immediately.

II. MACHINE OPERATION

1. Always wear safety gog-

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 warn-

ing decals on machine,

operator’s manuals, or job

site requirements. 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 discharge

hose while the engine is run-

ning.

5. Make sure that no one

is working in or on the

machine. Make sure the

discharge area is clear of

all persons, animals, etc.

Signal visually or audi-

bly that all is clear before

starting the engine. Keep

unauthorized personnel

away from the machine

and discharge hose at all times.

6. The driver of the towing vehicle is responsible for

the safety of the operator(s) and feeder(s) of the

machine. Make sure the driver is aware of and

avoids all possible hazards, such as tree limbs, low

power lines, etc.

7. Do not allow anyone to ride on the trailer or any other

part of the blower for any reason.

8. Never operate machine in

an enclosed area without

venting the engine exhaust

of both the equipment and

vehicle on which the equip-

ment is mounted. Deadly

carbon monoxide fumes

can accumulate.

9. Never operate this or any other machinery when

fatigued, tired, under the influence of alcohol, illegal

drugs, or medication. You must be in good physical

condition and mentally alert to operate this machine.

10. Never modify the machine. Never remove any part

of the machine (except for service and then reinstall

before operating).

3

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

anything out of the blower

hopper while machine is

in operation. Shut down

the engine using the OSHA

lockout/tagout procedure

(29 CFR 1910.147) before

removing any foreign

objects. Signal visually 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 in getting on and

off the blower, especially in

wet, icy, snowy, or muddy

conditions. Clean mud,

snow, or ice from steps,

fenders, and footwear.

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 acci-

dental starting, disconnect

battery cables. Tag the

engine operating area to

show that the machine is

being serviced. Use lock-

out/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

removing radiator cap, stop the engine and let the

system cool. Remove radiator cap only after the

coolant is cool.

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.

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 utilizing a minimum amount of manpower. The product to be

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

erosion and 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 a feed elevator. Located at the bot-

tom of the hopper is a drag conveyor that conveys the bulk material to an opening containing a

feed roll. The feed roll and drag conveyor feed the bulk material into an airlock. The airlock is spe-

cifically 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 chan-

neled through the pocket, carrying the material off and through the hose for discharge.

NOTICE

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

follow all instructions carefully.

TOWING VEHICLE

The truck used to tow the FINN BB-705 must be equipped with a 2-5/16-in. ball-type or pintle-type

hitch. This hitch should be mounted as near to the end of the truck bed as possible. The tow vehicle

should be fully wired for trailer marker, turn, and stop lights, as well as electric brakes, and be sized

to be able to pull and stop a 14,700 lb (6,670 kg) trailer. (Loaded 705 assuming 1000 yd3 mulch.)

NOTE: When towing tandem axle unit, always ensure the unit is level,

applying equal weight distribution across both axles.

CAUTION

When mounting a skid BB-705, be sure to follow the 705 skid-mounting instructions.

Ensure proper weight distribution and make sure the bark blower is properly supported by

the truck. When mounting a skid model, contact FINN Corporation for proper instructions.

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

could also result in product or property damage.

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 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. It 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 if 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 softwood like pine, and one is hardwood such as oak, the pine would go through at

a higher rate because it is easier to cut.

There are many different types of material that can be successfully processed through your Bark

Blower. These materials are categorized into three main groups. These classifications are impor-

tant when considering machine performance, material feed rate, and overall operation.

1. Dry Aged Material: Aged double- and triple-processed bark mulch, saw dust, or

wood shavings.

2. Green Material: Single-process hard wood mulch, green wood, or large

chunky material.

3. Wet or Heavy Material: Wet, heavy bark mulch and compost. Heavy fluid materials

such as sand, dirt or gravel.

Most importantly, when selecting a material, consider the greenness of the wood and its moisture

content. Wood that is well seasoned is easier to cut than green wood. It also processes better,

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

pack in the airlock vanes.

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

etc. These objects could cause bodily injury as well as damage to machine components, espe-

cially, the cutting knives in the airlock.

PRE-START EQUIPMENT CHECK

CAUTION

Equipment check is made with the engine off and all rotating parts stopped. Failure to com-

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

in product or property damage.

Safety check to ensure operator safety:

1. Check all trailer connections to the towing vehicle, as well as the condition of the safety

chains, and bolts connecting the ball coupler or pintle eye to the tongue.

2. Ensure that all guards are in place.

3. Tool Kit - see that it contains all prescribed items (see Tool Kit list, page 66).

4. Lubricate equipment - use hand gun only (see Lubrication Chart, page 22 and 23).

5. Check engine oil - refer to engine operator’s manual.

6. Check liquid coolant level in radiator and overflow tank. (Protected to -34ºF (-37ºC) when

shipped.)

8

7. Inspect the engine air cleaner (refer to the engine operator's manual), the radiator chaff

screen, and blower air cleaner for dust and dirt. If necessary, clean or replace the air filter.

8. Check fuel level. Use number 2-D diesel fuel oil unless operating at ambient temperature

below 40ºF (4ºC) or at an altitude exceeding 5000 ft (1524 m). In these instances, use

number 1-D fuel oil. Inspect the engine air cleaner, the radiator chaff screen, and the

blower air cleaner for dust and dirt.

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

ment.

10. Check the fluid level in the hydraulic tank. Proper level is midway between the upper and

lower indicator marks on the sight gauge. (See Lubrication Chart, pages 22 and 23 for oil

specification.)

11. Install the discharge hose, using clamps and gaskets provided with the machine.

CAUTION

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

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

comply could also result in product or property damage.

STARTING PROCEDURE

CAUTION

See safety section of the manual (pages 1 through 5) before operating the machine. Failure

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

result in product or property damage.

1. Place the remote control switch to the OFF position.

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

NOTE: This engine is equipped with a shutdown system that will shut the

engine off if the engine oil pressure drops below 15 psi (103.4 kPa)

or if the water temperature reaches 230°F (110°C). This shutdown

system is controlled by a relay that has a 15-second override peri-

od at start-up. If the key switch is left in the RUN position too long

without the engine running, the Key Reset Light will come on to

prompt you to turn the key switch OFF prior to any further attempts

at starting.

3. Check that the ON/FUSE and the DOOR SWITCHES lights are illuminated. If the green

DOOR SWITCHES light is not lit, check that the door above the airlock is tightly closed. If

both lights are off, but the voltmeter is reading correctly, check the 10-amp circuit breaker

in the control box. If the voltmeter also shows no reading, then check the 30-amp circuit

breaker in the control box.

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

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

control the engine speed. This is a good place to start, refer to page 15, BARK BLOWER

ADJUSTMENTS for further information on control settings. Governed engine speed should

be 2,500 to 2,700 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 skid steer, bucket loader, belt con-

veyor, or optional feed conveyor to dump 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:

SUBSYSTEM 1: MATERIAL-HANDLING GROUP

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

floor, the feed roll, and the airlock.

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

direct driven off the engine flywheel by a coupling. Therefore, whenever the engine is running, air

is being pumped. The blower is equipped with a relief valve limiting maximum air pressure to 12

psi (82.7 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 mate-

rial to the airlock. The feed roll is powered by a variable speed hydraulic motor, which also powers

the drag conveyor through a chain drive.

The airlock receives the material from the drag conveyor and pressurized air from the blower. Its

primary function is to convey the material from the atmospheric air to a sealed chamber where the

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

material, the airlock housing is equipped with cutting knives 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 direct-coupled to a gearbox and driven by a bi-rotational

hydraulic motor.

SUBSYSTEM 2: HYDRAULIC SYSTEM

Hydraulic power for the Bark Blower is generated by a fixed-displacement pump driven off the

engine auxiliary drive. The pump receives DTR13 hydraulic fluid from the 32-gal (120-L) reservoir

through a service valve and suction hose, then delivers it to the valve manifold through an unload-

ing valve. The manifold has five separate valve sections with solenoids that control all the func-

tions on the Bark Blower. Also, it uses equal to or better than 5 micron absolute filtration.

10

DESCRIPTION OF VALVE SECTIONS

Figure 1 shows the valve block and the different hydraulic circuits. Each circuit, except 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 screw driver 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, and 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 so-

lenoids for their respective circuits.

Figure 1 - Valve Block

A. 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.

B. FLOOR (DRAG CONVEYOR)/FEED ROLL

The middle valve controls the floor and feed roll speed. It is an electrically-driven proportional

valve that is controlled by the Floor Speed toggle switch on the control box. Toggling the switch

up or down varies the input voltage to the solenoid and moves the spool in the valve accordingly,

allowing more or less oil flow to the floor and feed roll. There is a pressure switch on the forward

circuit that is set for 2,050 psi (14,134 kPa) that triggers the auto-reverse function on the floor.

C. AGITATOR

Not used.

D. SEED INJECTION

E. HOSE REEL

The last section of the manifold controls the hose reel. The flow rate is factory-set so that the hose

reel winds, and unwinds at a rate of about 13 rpm.

SUBSYSTEM 3: HYDRAULIC CONTROL SYSTEM

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

Bark Blower. This 12V DC system runs off the engine electrical system. It is a series of relays, tim-

ers, and analog and digital controllers, located in the electrical control box on the rear passenger-

side of the machine, which control 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 lights up if the circuit is active. This is an easy way to check

if a particular circuit has electrical power.

When the START button is pushed, the CR1 and CR2 relays are energized. This in turn energizes

the forward solenoid on the airlock valve section, starting the airlock. If the floor toggle switch is

ON, the floor and feed roll solenoid is also energized after a short delay Timer relay TR3 stops the

floor for a brief moment so the airlock always has a chance to clear itself. TR3 should time out after

0.5 second, at which point the floor and feed roll will begin to move at a speed relative to the Floor

Speed display in the forward direction. As material drops into the top of the airlock, the pressure

required to cut the material is monitored by the pressure switch located in the bulkhead connector

of the forward direction of the airlock valve section in the manifold. The switch is normally open.

When the airlock motor stalls due to the rotor encountering an object it can not cut, high pressure

(approximately 2,400 psi (16,547 kPa) is created in the airlock circuit and the pressure switch clos-

es. The amount of time the pressure switch is closed is monitored by the timer relay TR1 in Figure 2.

If the switch remains closed for more than 0.5 second, TR1 energizes timer relay TR2. TR2 auto-

matically reverses the rotor by energizing the reverse solenoid and de-energizing the forward sole-

noid. It also de-energizes the floor solenoid, shutting off the floor and feed roll. The airlock will

remain in reverse until TR2 times out, which is approximately 1 second. Timer relay TR3 will then

restart the drag conveyor after allowing the airlock to clear itself. Located on the control panel is an

airlock auto-reverse test button. If there is ever a problem with the airlock not auto-reversing, this

can be a useful troubleshooting tool.

The feed roll/floor circuit is capable of being reversed manually from the electrical control box to

clear jams. To use the feature, the STOP button must be pushed and the blue and green indictor

lights must be on. The FLOOR SWITCH is a three-position switch with a momentary reverse fea-

ture. Pushing the switch down to reverse the feed roll and floor sends power to the TR4 relay. The

floor and feed roll will reverse until TR4 times out, which is approximately 2 seconds. This setting

will clear most jams.

There is a normally open pressure switch located in the bulkhead connector of the forward direc-

tion on the feed roll/floor valve section. The pressure switch monitors the pressure in the feed roll/

floor circuit. If the pressure in the feed roll/floor circuit reaches the set pressure of the this switch

(approximately 2,050 psi (14,134 kPa), an electrical signal is sent to TR4 to trigger the feed roll/

floor to auto-reverse for 2 seconds, and then re-start in forward to clear any obstruction.

When the STOP button is pushed, power is cut to the relays. This stops the hydraulic motors on

the airlock and feed roll by shutting off power to the solenoids. The hydraulics can also be stopped

by shutting off the ignition key. Please note that the hydraulics will also stop if the rear door on the

feed roll housing is opened and cannot be restarted until they are closed and the START button is

pushed.

SUBSYSTEM 4: RADIO REMOTE TRANSMITTER

This Bark Blower is equipped with a Kar-Tech® Radio Remote Transmitter to control the MATERIAL

START/STOP, the MATERIAL DECREASE/INCREASE, and the ENGINE RPM INCREASE/

DECREASE. It also contains an Emergency Stop button that activates the Murphy shutdown sys-

tem on the engine.

If using the Radio Remote Transmitter, a certain start-up sequence must be followed to activate

the remote. When using the remote, start as follows:

1. Place the Radio Remote Transmitter On/Off switch, located on the control box, to the OFF

position.

2. Place the switch, located on top of the Radio Remote Transmitter, to the OFF position.

3. Start the engine and allow to warm up as specified in the Bark Blower instruction manual.

4. Place the Radio Remote Transmitter switch, located on the control box, to the ON position.

5. Place the Radio Remote Transmitter switch to the ON position.

To utilize the Material Feed Start/Stop feature of the Radio Remote Transmitter, the initial start

must occur at the Start/Stop station on the Bark Blower. The hard-wired, Start/Stop on the unit

is the primary and overriding set of controls. When either the STOP button is pushed or a loss of

power to the relays occurs (i.e. the rear door on the feed roll housing is opened or a circuit breaker

trips), the Feed Start/Stop feature on the Radio Remote Transmitter is deactivated. This feature

will remain inactive until the initial start is once again made at the machine by pressing the START

button.

The Material Increase/Decrease function on the Radio Remote Transmitter can be used to change

the floor speed and effectively adjust the output of mulch from the machine. Adjustments to the

floor speed made from the Radio Remote Transmitter will be shown on the FLOOR SPEED display

on the control box.

The Engine Increase/Decrease function on the Radio Remote Transmitter adjusts the throttle actu-

ator on the engine. For use of the engine rpm function, refer to MULCHING WITH THE BARK

BLOWER on page 14.

Pushing the red button located next to the antenna on the Radio Remote Transmitter activates the

Murphy shutdown system. This will shut off the engine, automatically return the engine throttle

back to idle, and cut power to all the relays which will shut down all of the hydraulics. To reset the

safety system:

1. Flip the Radio Remote Transmitter On/Off switch to OFF.

2. Re-start the engine.

3. Flip the Radio Remote Transmitter On/Off switch to ON.
