2
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 procedure (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 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
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.
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 pre-
heater, 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 penetrate the skin or eyes
and cause injury, blindness, or death. To check for
such leaks, use a piece of cardboard 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 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.
