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.

OPERATION AND MAINTENANCE MANUAL
FOR THE B230 STRAW BLOWER
INTRODUCTION
This manual is designed for step-by-step instructions of the operation, care, and maintenance of
the B230 Straw Blower and, in addition, it contains illustrations and descriptions of a complete list
of parts and components for easy identification. For best results and to ensure longer life of the
equipment, please follow the instructions carefully. For your safety, read the entire manual before
operation of this unit.
DEFINITION OF MULCHING
Mulching is the process whereby a vegetative mulch, such as hay or straw, sometimes excelsior,
or other wood product or other vegetative material, is spread on previously seeded areas to
promote germination, while providing temporary erosion control.
THE FINN B230 STRAW BLOWER AND HOW IT WORKS
The FINN B230 Straw Blower will apply vegetative mulch at a fast and uniform rate, utilizing a
minimum amount of manpower.
The baled vegetative mulch material is placed on the feed chute by the bale feeder. With the
B230 unit there is no need for the person loading the feed chute to break the bales apart. This
unit has a bale breaker/pick wheel that mechanically breaks the bales before they enter the
shredder box. In the shredder box, a combination of beater chains and air currents separates
the mulch into individual fibers that are drawn into the blower housing and blown through the
discharge assembly onto the seedbed.
TOWING VEHICLE
The truck used to tow the FINN Straw Blower should have a bed large enough to carry the
quantity of mulch needed for economical operation. If the Straw Blower is going to be used on
rough, hilly terrain, a truck with a two-speed axle is suggested. This will supply the necessary
slow speed required for careful, uniform application.
The truck must be equipped with a pintle hitch with a large enough rating to tow the Straw
Blower. There must be provisions for the safety chains to be attached. The hitch should be
mounted as near the end of the truck bed as possible.
LOADING BALES
Load the bales of mulch on the truck bed with binder twine or wire on top rather than on the
side. This makes it easier to grab the bales while the Straw Blower is in operation. Place the first
layer of bales “lengthwise” on the truck. The second layer of bales should be placed “crosswise”.
Alternate successive layers lengthwise and crosswise in order to secure the load. Leave enough
room at the rear of the truck bed for the bale handler to stand.

8
EQUIPMENT CHECK
Equipment check should be made with the engine OFF and all
rotating parts stopped. Failure to comply could result in death or
serious injury.
1. Tool kit - make sure that it contains all prescribed items (see tool kit list).
2. Check shredder box for foreign objects that could damage the equipment or injure
workers.
3. Check fuel tank and fill as required. Refer to engine operator’s manual for fuel
specifications and requirements.
4. Check engine oil and fill or change as required. Refer to engine operator’s manual.
5. Check liquid level in radiator and overflow tank. Refer to engine operator’s manual.
6. Inspect air cleaner for dust and dirt.
A. Knock the loose particles from element.
B. Wash with water and detergent. Do not pressure wash.
C. Rinse and allow to dry. Do not force dry, do not use compressed air or heat.
7. Engage and disengage clutch to determine if it “snaps” in and out of engagement.
8. Check beater chains and their mounting pins for damage or wear. Replace if necessary.
9. Lubricate equipment. Use hand gun only (see lube chart).
10. Check belts for proper tightness. Belts are in proper adjustment when 8 lb (3.6 kg)
pressure in the center of the belt, produces 3/8 in. (1 cm) depression.
POSITIONING THE FEED CHUTE EXTENSION
The feed chute extension, when opened, should extend at least 18 in. (45 cm) over the rear edge
of the truck bed. To achieve this, use the following:
1. Unhook the discharge spout holddown and fold it down to the horizontal position.
2. Move the discharge tube to the side.
3. Move the feed chute extension down to the feed position. If the extension is short of the
edge of the truck bed, move it to the rear set of mounting holes.
4. Next, adjust the feed chute so that it is 6 to 12 in. (15 to 30 cm) higher than the bed of the
truck.
5. Be sure that, when turning the truck, the payload does not come in contact with the feed
chute.
PRE-START CHECK
Safety check to ensure operator safety:
1. Inspect the bolts on the hitch and safety chains, the brakes, and the trailer lights.
2. With ignition ON, check the amber safety light. Check the safety switches if the amber
safety light is not flashing.
3. Check that the signal horn operates properly.
4. Ensure that all guards are in place.

STARTING PROCEDURE
See safety section of the manual (pages 1 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. Make sure the fuel filter/water separator fuel cock is in the ON position.
2. Disengage the PTO clutch.
Never use an engine starting aid such as ether. Engine damage will
result. Prime the engine before starting. If air is mixed in the fuel,
damage to the supply pump and the injector may result.
3. Insert the key into the key switch. The control panel
is powered from the engine battery connection from
the engine harness connector. Make sure the engine
harness is connected to the control panel before
proceeding.
4. Power up the system by turning the key switch to the
ON “ ” position. This will activate the control panel
and apply power to the engine ECU. The system
automatically energizes the glow plug relay and keeps
it energized for a set amount of time depending on the
cooling water temperature.
NOTE:Aglow plug assists starting in cold weather conditions.
If the control panel indicates a fault condition, DO NOT start the
engine. Review the fault condition and correct the condition before
starting the engine. See Fault Codes section for details on system faults.
5. Turn the key clockwise to the START “ ” position. Release the key as soon as the
engine starts. It will return to the ON position. If a fault condition exists, the engine ECU
may prevent the engine from starting. All fault conditions will be indicated by the digital
display. The display will indicate the active fault(s) by presenting a pop-up graphic
describing the fault condition.
Never hold the key in the START position for longer than 15 seconds
or the starter motor will overheat.
6. If the engine fails to start:
a. Wait until the engine comes to a complete stop before you attempt to start it again.
Engaging the starter while the engine is still rotating will result in damage to the starter
and flywheel.
b. Wait at least 30 seconds before you attempt to start the engine again. This procedure
will allow the battery voltage to recover and prevent damage to the starter motor due
to a low battery voltage.
7. Once the engine is started, the control panel will set the engine speed to
the minimum RPM speed setting. To change the engine speed, toggle the
throttle control switch (“Fast-Rabbit/Slow-Turtle”) to the desired speed
setting. The engine speed cannot be set below the minimum RPM speed
setting or above the maximum RPM speed setting.
8. With the engine still idling, engage the clutch slowly. Move the throttle to
wide-open position and let the governor control the engine speed.
Do NOT engage the PTO clutch above 1000 RPMs or damage to the
PTO clutch will occur.

10
SHUTTING DOWN THE ENGINE
For maximum engine life, allow the engine to idle, without load, for five minutes. This will allow
the engine components that operate at high temperatures, such as the turbocharger (if equipped)
and exhaust system, to cool slightly before the engine itself is shut down.
Follow these steps to shut down the engine:
1. Disengage the PTO.
2. Set the engine speed control to its lowest setting.
3. Run the engine at low idle speed for at least five minutes before you shut it down.
4. Turn the key to the OFF “ ” position, and remove the key from the switch.
CREW MEMBERS AND THEIR DUTIES
1. The Operator controls the placement of the mulch on the seedbed by moving the
discharge assembly. He also controls the movement of the towing truck along the
seedbed by using a predetermined set of hand or horn signals.
2. The Bale Handler operates from the truck bed and supplies the feeder with bales of mulch
material, cut side up.
3. The Bale Feeder cuts and disposes of the twine or wire. He keeps the power feed chute
full of material with no gaps so there will be no interruption in distribution of mulch to the
seedbed.
4. The Truck Driver follows the directions of the operator for the movement of the towing
truck. The truck driver should be cautious in starting or stopping the truck so that the crew
members are not thrown off balance.
FEEDING THE MULCH
The power feed assembly of the FINN Straw Blower has been designed to give fast, uniform
mechanical feeding. The adjustable feeding rate allows the use of various materials, and at the
same time obtains maximum production. The power feed assembly is driven by a power feed
chain. This allows the mulch material to be fed at an adjustable rate to the separator roll, which
drops the bats into the shredder housing.
The power feed chain is driven by a hydraulic motor mounted on the top side of the power feed
chute. This motor is controlled by the operator at the discharge control station. The power feed
control is a lever that, when pulled back from the center position, makes the power feed chain run
away from the shredder housing. When pushed forward from the center position, it causes the
power feed chain to move toward the shredder housing. Either forward or rearward, the farther
the lever is moved, the faster the chain travels. Once a speed has been selected, centering the
lever stops the chain. If the lever is returned to its previous position, the chain will move at the
previous speed. Through use of the power feed control lever, the operator can momentarily stop
the feeding cycle when wet bales are encountered or when it is necessary to stop application
because of driveways, bridge abutments, etc. The operator can slow down or speed up the rate
of feeding depending on the type of material that is being encountered per bale.
To start the power feed, push the control lever slowly until the desired speed is reached. It is
necessary for bale handlers to keep the power feed chute completely full at all times in order to
get the maximum production rate of the FINN Straw Blower.

11
FEEDING THE MULCH (CONTINUED)
The operator should have a full stream of mulch coming at all times and should be directing
the material to the area being mulched. The operator has complete control of the power feed
mechanism by the use of the control lever and can vary the rate of feed instantaneously to fit
all conditions. If the bale handlers are unable to keep the feed chute full, the operator should
slow the feed down slightly until the bale handlers can keep up. This will allow a more uniform
application. If the feed rate is not fast enough for good, bright straw, and the control handle is full
forward, move the handle to the right and then forward into the high-speed forward slot.
It is suggested that with every truckload of mulch, the power feed tray should be emptied. This
will allow the operator to remove any wire or twine from around the feeder roll.
Rate of feed should never be set beyond the capacity of the machine so as to compensate for
the poor quality of mulch material being used. Failure to comply could result in overloading of the
machine, which causes extensive wear and maintenance problems.
DISTRIBUTING THE MULCH
The Straw Blower should be towed to a point approximately 60 ft. (18 m) from the area where
mulch is to be applied. The operator elevates the discharge spout about 10 degrees above the
plane of the seedbed so that the mulch floats onto the seedbed.
NOTE:Do not drive the mulch into the seedbed with air pressure. The higher the tube is held,
the more uniform the application will be.
A full circle horizontal travel of the discharge spout allows the operator to vary the direction of
the discharge spout according to the prevailing winds. The tube should never be directed into the
wind, towards any persons, or at the towing vehicle.
SMOOTHING OUT MULCH PATTERNS
The lower roll assembly in the shredder housing, driven by the blower power band, is equipped
with mounting points for eight beater chains and six fingers. For normal straw application, only
four to six chains are needed. If you have material coming out in lumps or find it impossible to
handle because the mulch is wet or hard, install extra chains in pairs until smoothness of mulch
application is reached.
Be sure beater chains are mounted opposite each other at all times
to avoid throwing the blower shaft out of balance. Failure to comply
could result in minor to moderate personal injury. Failure to comply could also result in
product or property damage.
If your equipment is still throwing mulch material out in lumps and does not have a good
discharge pattern, move the last beater hub closer to the blower housing, but within the shredder
box.

12
CLOGGING OF THE MULCH BLOWING SYSTEM
If during operation the machine gets plugged, simply shut off the power feed. If the machine does
not clear, disengage clutch and let the machine coast to a stop. Before turning off the engine,
the operator can reverse the power feed chain using the control lever. This will unload the power
feed chute to facilitate cleaning the machine.
Do not reach into the shredder box or attempt to make any
adjustment until the engine and all rotating parts have stopped.
Failure to comply WILL result in serious personal injury or death.
Four access locations have been provided to allow the removal of any obstructions:
1. The opening into the beater box into which the mulch material is fed.
2. The access door in the shredder housing.
3. The access door into the blower discharge transition.
4. The discharge tube itself.
When the obstruction has been removed and access doors closed, the motor can be restarted
and mulch application continued.
If consistent plugging occurs, it can be caused by one of several reasons:
1. The bale handlers do not feed the bales at a consistent rate and/or do not guide the bales
properly onto the power feed mechanism, leaving gaps in the stream of bales or leaving
the bats laying flat on the tray.
2. The power band is out of adjustment, causing it to slip.
3. The clutch is out of adjustment and is slipping.
4. Incorrect type or quantity of beater chains are installed.
5. Operator is feeding the mulch material too fast, overloading the shredder housing.
