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.

SAFETY FIRST
With any piece of equipment, new or used, the most important part of its operation is SAFETY!
FINN Corporation encourages you and your employees to familiarize yourselves with your new
equipment and stresses safe operation.
The first five pages of this manual are a summary of the main safety aspects associated with
this unit. Be sure to read and understand completely before operating the machine.
The symbols below are used throughout the operation and maintenance sections
of this manual to call attention to safety procedures.
Danger indicates an imminently hazardous situation which,
if not avoided, WILL result in death or serious injury.
Warning indicates a potentially hazardous situation which,
if not avoided, COULD result in death or serious injury.
Caution indicates a potentially hazardous situation which,
if not avoided, MAY result in minor or moderate injury.

MAY cause damage to equipment.
NOTE:This is helpful information.
CALIFORNIA PROPOSITION 65
The engine exhaust and some of its constituents are
known to the State of California to cause cancer, birth
defects, and other reproductive harm. Wear protective equipment. To minimize
exposure, avoid breathing exhaust, do not idle the engine except as necessary,
service your vehicle in a well-ventilated area and wear gloves or wash your
hands frequently when servicing your vehicle.

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 is the correct size for the
coupler.
2. Check that all guard railing is in place and secure.
3. Verify that all guards are in place.
4. By carefully looking in the shredder box, inspect the
shredder box for foreign objects.
5. With the ignition switch ON, verify that the signal
horn is operating correctly.
6. Make sure no one is working on or inside the
machine. Give a visual and audible signal that all is
clear before starting the engine.
II. MACHINE OPERATION
1. Always wear safety goggles when
operating 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 operate the machine without
all guards in place.
II. MACHINE OPERATION (Continued)
3. Make sure the discharge area is clear of all
persons, animals, etc.
4. The driver of the carrying or 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 to the
operator(s) on the machine, such as tree limbs,
low power lines, etc. Vehicles on which equipment
is mounted or towed must be started or stopped
gradually. Avoid abrupt starts and stops. Never
operate on a slope or a hill that may endanger the
operator(s). All personnel should review and be
familiar with start/stop signals between the driver
and operator(s) before operation of the equipment.
5. Operator(s) of equipment should
never ride on machine at speeds
greater than 5 MPH (8 km/h).
6. Never operate machine in an
enclosed area without venting the
exhaust of both the equipment and
the vehicle on which the equipment
is mounted or towed. Deadly
carbon monoxide fumes can
accumulate.
7. 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.
STRAW BLOWER SAFETY SUMMARY SECTION
It is important that all operators of this machine are familiar with all safety aspects men-
tioned below, and have read the entire Operator’s Manual 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 sheet. 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. Above all, remember that safety is up to
you.
The FINN STRAW BLOWER is intended to be used as an applicator of vegetative hay or straw mulches
onto the seedbed. Its use with other products or for other applications must be by approval of the prod-
uct’s manufacturer. If there are any questions, contact FiNN Corporation at 1-800-543-7166.

II. MACHINE OPERATION (Continued)
8. Never modify the machine. Never
remove any part of the machine
(except for service and then
reinstall before operating).
9. Use proper means for mounting and dismounting
of machine. Never mount or dismount a moving
machine.
10. Do not aim discharge at people, animals, etc. Only
aim the discharge at the intended seedbed.
11. Do not open any doors or access panels while
machine is in operation. Severe injury may result
from rotating parts.
12. Do not attempt to pull anything
out of the feed chute or shredder
box when machine is in operation.
Shut down the engine and
ensure non-operational machine
state using the Occupational
Safety and Health Administration
(OSHA) lockout/tagout procedure
(29CFR 1910.147) before removing
any foreign objects. Give a visual
and audible signal that all is clear
before restarting the machine.
III. MAINTENANCE
1. Before servicing the machine, turn
off engine and allow all moving
parts to stop. Disconnect the
battery cables to prevent accidental
starting of the machine. Tag the
engine operating area to show that
the machine is being serviced. Use
OSHA lockout/tagout procedure (29CFR 1910.147).
2. Perform general maintenance such
as checking the safety chains,
hitch, hitch bolts, tires, and
brakes. Repair or replace if worn
or broken. Never operate machine
on improperly inflated or damaged
tires. Always use a safety cage or
cable restraints when reinflating a repaired tire.
III. MAINTENANCE (Continued)
3. Battery maintenance. Lead-acid
batteries contain sulfuric acid,
that will damage eyes or skin
on contact. Always wear a face
shield to avoid getting acid in the
eyes. If acid contacts 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 gases. Keep
arcs, sparks, flames, and lighted tobacco away.
4. Filling of fuel. Never fill the fuel tank while the
engine is 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 fuel lines, tanks, or containers. Move at least
10 feet (3 meters) 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 used fluids and dispose of them properly.
5. It is recommended that only authorized, genuine
FiNN replacement parts be used on the machine.
6. Make certain that all decals on the machine are
maintained in good legible condition. Replacement
decals are available through FiNN Corporation by
specifying the part number shown in the lower right-
hand corner of the decal. See page 4 for the current
set of safety decals mounted on the unit. See Parts
Manual for the location and quantity of all decals on
this unit.
7. 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.
