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. Confirm 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 filled 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 confirm with your sales representative that this has been done.
This registration process activates the Finn Limited Warranty.

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. Donotoperatethemachine
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.

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 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 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, fend-
ers 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 on rough surfaces and side
slopes carefully, 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 accidental
starting, disconnect battery
cables. Tag the engine oper-
ating area to show that the
machine is being serviced.
Use lockout/tagout proce-
dure (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 man-
ner. Failure to do so could result in component dam-
age, 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 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.
