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 offon
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.

MATERIAL 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. If you have a chassis-mounted unit, check devices
securing unit to the truck or trailer frame.
If the unit is a trailer unit, check
hitch and hitch bolts, lights, brakes,
and all safety components. 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 are found, replace affected part
immediately.
II. MACHINE OPERATION
1. Always wear safety goggles when
operating and/or feeding the
machine. Other safety attire, such
as safety shoes, ear protection,
gloves, hard hats, dust masks,
etc., should be worn as required
by warning 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 airlock door or discharge. If
switches 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 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 audibly 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 unit for any reason.

3
15. When leaving the blower unattended for any
reason, be sure to:
A. Shut off the material feed system using the
FLOOR controls on the control panel or
MATERIAL controls on the remote.
B. Shut off vehicle engine and blower engine.
C. Place transmission of the vehicle in
“NEUTRAL” or “PARK”.
D. Set parking brake firmly.
E. Remove keys from blower unit.
F. Lock vehicle cab and take all keys with you.
G. If parked on a steep grade, block the wheels.
These actions are recommended to avoid
unauthorized use, runaway, vandalism, theft, and
unexpected operation when the equipment is
unattended.
16. Do not read, eat or otherwise lose or lessen your
attention in any manner while operating the blower.
Operating this 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 in/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 Emergency Stop
(e-stop) button depressed on the
remote control hand held unit when unit 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 unit.
8. Never operate machine in an
enclosed area without venting
the engine exhaust of both the
equipment and vehicle on which
the equipment 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).
11. During application through the hose, high pressure
can be exerted at the end of the hose. Hose-holding
personnel must establish good footing. The operator
should only increase the engine RPM which
increases the volume of air in 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 discharge 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 and lockout the engine
using the OSHA lockout/tagout
procedure (29 CFR 1910.147)
before removing any foreign objects. Signal visually
and audibly that all is clear before operating the
machine.

4
6. It is recommended that only authorized, genuine
FINN replacement parts be used on the machine.
7. Do not use ether 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 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.
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.
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 operating
area to show that the machine
is being serviced. 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
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 contact. Always wear a face
shield to avoid getting acid in the
eyes. If acid contacts the eyes,
flush immediately 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 running, 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 or
near 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 contaminate the
surrounding environment. Collect all fluids and
dispose of them properly.

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 MATERIAL BLOWER AND ITS FUNCTION
The FINN Material 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 composted 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
maintenance of the Material Blower. In addition, it contains illustrations and a complete list of
parts and components for easy identification.
HOW THE MATERIAL BLOWER WORKS
The bulk material is loaded into the hopper by a loader or by a feed elevator. Located at the
bottom of the hopper is a drag chain conveyor that conveys the bulk material to an opening, in
the rear of the hopper, containing a feed roll. The feed roll and drag chain 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 volume/
low pressure air stream, created by the blower, is channeled through the pocket, carrying the
material out of the airlock and through the hose for discharge.
For best results and to ensure safe operation and long life of the
equipment, please read and follow all instructions carefully.

MOUNTING THE MATERIAL BLOWER
A complete mounting kit is provided with the unit.
Before selecting a chassis for the Material Blower, carefully review this manual and consider the
following:
A. Never exceed either the Gross Axle Weight Rating (GAWR) or the Gross Vehicle Weight
Rating (GVWR) for the chassis.
B. Install the Material Blower only onto a vehicle with cab-to-axle dimension sufficient to fully
support the Material Blower frame length.
C. Position the Material Blower such that the required clearance zones are maintained.
Once the proper carrier has been selected, the blower must be securely mounted onto it.
The FINN Material Blower should be mounted by a qualified truck body
installer. Failure to comply could result in personal injury. Failure to
comply could also result in product or property damage.
Install/Mount the FINN Material Blower in compliance with the vehicle
ratings, machine mounting requirements and applicable laws. Failure
to do so could result in personal or property damage.
The mounting of the blower to the truck must allow for tire clearance
as well as frame twist.
Follow mounting instructions given in the Truck Mounting / Loading Information section. Consult
truck manufacturer for proper truck sizing and mounting recommendations. If mounting conditions
require deviation from these instructions, consult the factory.
