• Use genuine factory parts or parts with
equivalent characteristics, including
type, strength and material. Failure to
do so may result in product malfunc tion and possible injury to the operator
and/or others.
• Replace locknuts and locking screws
if you can tighten them without feel ing considerable resistance for sev eral turns before they are completely
tight. Replace them with factory autho-
rized parts or their equivalent.
• If hardware is not secure, or if some
of the hardware is over-tightened,

• Never allow hands, clothing or any
part of the body to enter the discharge
chute or near moving parts.
• Keep your face and all body parts
away from inlet and discharge
openings.
• Avoid wearing loose-tting clothing.
• Wear approved eye and ear protection
while operating the machine.
• The machine should be operated on
level surfaces only.
• Before starting the machine, visually
inspect all nuts, bolts and other
fasteners to see that they are properly
secured. Nuts, bolts and other
fasteners should be checked every 8
to 10 hours of operation for proper
alignment and tightness.
Operation
• Make certain the impeller chamber is
empty before starting the machine.
• If a foreign object should strike the
impeller mechanism of the machine
and cause an unusual noise or
vibration, shut the engine or PTO off
immediately and allow it to come to a
complete stop. Disconnect the spark
PTO shaft from the power unit, and
then do the following:
1. Inspect for damage.
2. Repair or replace any damaged
parts.
3. Check for and tighten any loose
bolts, nuts, fasteners or parts.
• Keep debris material from building up
in the discharge and inlet area, as this
may prohibit proper discharge of
airow and can cause poor
performance.
• Keep the impeller inlet area clean from
debris and other accumulations.
• Stay away from the discharge area
when machine is in operation.
• If the Debris Blower should become
clogged, shut off the engine or PTO
and allow it to come to a complete
stop. Disconnect the spark plug wire
from the spark plug or PTO shaft
before clearing debris.
• Do not allow hands, clothing or any
part of the body to enter the discharge
chute, impeller inlet or near any
moving parts.
• Replace damaged or missing safety
decals.
• Keep hands, feet and clothing away
from PTO driven parts.
• Keep all guards and shields in place
during operation. Disengage PTO and
shut off the engine before removing
guards or shields.
• Never attempt to adjust, clean or
lubricate the machine while it is in
operation.
• Operator should never wear loose
clothing when working around PTO.
• Before starting tractor, make sure that
the transmission and PTO are
disengaged.
• Make sure the tractor’s engine is at
idle speed before engaging the PTO.
• Be sure the tractor’s engine is at idle
before changing the airow of the
Debris Blower Diverter.
• Keep all safety shields and guards in
place and in good working condition.

Assembly Operation
1. Remove from crate.
2. Mount Diverter Handle Assembly to
the frame of the machine with the two
3/8” bolts already in the frame.
SAFETY WARNING!
• Wear approved eye and ear
protection while operating the
Debris Blower.
3. Connect PTO shaft to input shaft of
machine, tighten set screws on shaft.
4. Mount 3-point pins on Debris Blower.
5. Mount Debris Blower to 3-point of trac tor and connect PTO shaft.
Note:
A set of belts between the PTO shaft
and the impeller shaft assembly drive the
fan blades whenever the PTO drive-shaft
is turning.
On initial operation of the Debris
Blower, the belts may shrink and need
readjustment after the rst hour of use.
When readjusting belt tension, use a
straightedge across the faces of pulleys to
make sure they are properly aligned and
the belts will run true.
SAFETY WARNING!
• Keep pants and loose clothing away
from PTO drive and shaft and all
drive pulleys, belts and shafts.
• Never operate the Debris Blower
beyond the suggested 540 PTO
speed.
• Do not attempt to service machine
while it is in operation.
• Keep all guards in place during
operation. Never operate the Debris
Blower with safety shields removed.
• Before operating the machine,
check to ensure that all belt guides
and tensioner are in place to
prevent belts from slipping off the
pulleys and systems from being
accidentally engaged.
• Check inlet and discharge housings
for children, pets and foreign
objects before operating.
• Keep clothing and all body parts
away from rotating parts. Do not
wear loose tting clothing.
• Periodically clean debris material
away from the machine to lessen
the possibility of re. Always keep a
re extinguisher near the Debris
Blower during operation.
• Impeller blade rotation cannot be
controlled from the Debris Blower.
• Obtain and wear safety glasses
when operating this machine.
Note:
A safe operator is one who practices
safety and uses good common sense to
protect himself from ying material.

Debris Blower
To begin operation:
1. Mount Debris Blower to 3-point of trac tor and connect PTO shaft to tractor
output shaft.
To stop operation:
1. Move throttle on tractor to the slow
position and disengage the PTO lever
on the tractor.
2. Adjust center link on tractor so that the
Debris Blower is setting level at the
ground surface while 3-point hitch is in
FLOAT position.
3. Move Diverter Handle to the desired
output direction.
4. Engage PTO lever on the tractor AT
IDLE SPEED of the tractor and begin
operation of the Debris Blower.
5. If the operator needs to change direc-
tion of airow of the diverter, make
sure the tractor is at idle speed.
6. If it is necessary to inspect or work on
the Debris Blower, always disengage
the PTO shaft and shut off the tractor
engine before doing so.
2. Shut off the tractor engine and allow
the machine to come to a complete
stop.

• The Impeller is heavy and will con-
tinue to turn even though the opera tor has shut off the power source.
• Do not attempt to service or inspect
the machine until you see that the
shafts have stopped turning and
that there is no noise coming from
the machine.
SAFETY WARNING!
• Belts may become severely dam-
aged by engaging PTO shaft at high
RPM.
• To avoid personal injury, always
keep face and body parts away from
inlet and discharge openings.

tension can cause premature bearing and
belt failure.
Use a straightedge to check alignment
across the faces of pulleys after adjusting
belt tension to ensure that the belts will
run true.

every 15 hours of use.
2. There are 8 grease ttings on the
unit:
2 on the PTO Shaft
2 on the Input Shaft
2 on the Impeller Shaft
