Wire Harness Installation
A wire harness is needed to activate the
rotation and deflection. If the loader is
equipped with an attachment control package,
the appropriate harness should be installed
from the factory.
If the snowblower was ordered with the pistol
grip control harness, follow these instructions:
1. Install the control handle on either steering
lever, whichever you prefer, with two (2)
hose clamps.
NOTE: The control handle bracket can be
positioned several different ways. We
recommend it be positioned as shown.
2. Put a cable tie around the wiring harness
and the steering lever.
3. Install the wire harness receptacle bracket
on either the loader arm or near the
hydraulic quick couplers.
NOTE: It may be necessary to make an
adapter bracket in order to attach the wire
harness to the loader.
4. Route the wire harness back along the
loader arms and fasten with cable ties.
IMPORTANT: Be sure to leave some slack
in the wire harness where the loader arms
pivot to prevent stretching the harness.
Make sure the harness is fully secured to
prevent snags or pinching.

__________________MOUNTING INSTRUCTIONS_____________
After the initial set-up assembly is completed use the following procedure to mount the snowblower to the
loader for user operation.
1. Use the step, treads, and grab handles to
get on and off the loader and snowblower.
2. Sitting in the operator’s seat, lower seat bar
and fasten the seat belt.
3. Drive the loader to the rear of the
snowblower. Put the loader quick attach
coupler into the snowblower mounting
bracket.
4. Tilt the loader coupler backward a small
amount until it is fully engaged in the snow
blower mounting bracket.
5. Stop the engine and engage the parking
brake.
6. Secure the coupler locking mechanism that
attaches the snow blower to the loader.
Coupler wedges or pins
must extend through the holes in
attachment. Levers must be fully down
and locked. Failure to secure wedges or
pins can allow attachment to come off
and could cause injury or death.

13
____________________MOUNTING INSTRUCTIONS________________
7. Connect the hydraulic quick couplers from
the snowblower to the loader.
IMPORTANT: Make sure the quick couplers
are fully engaged. If the quick couplers do
not fully engage, check to see that the
couplers are the same size and brand. Do
not force the quick couplers together.
IMPORTANT: Wipe the ends of the hydraulic
quick couplers (both lead and loader) with a
rag to remove any possible contamination.
Contamination can cause hydraulic
components to fail and is not covered under
warranty.
NOTE: Attachment is shipped with 12FJX
(1-1/16” Female JIC Swivel) fittings on the
ends of the lead hoses.
NOTE: Make sure the pressurized hose is
routed to the “P” port of the valve block. If it
isn’t, the blower will not operate properly.
NOTE: The pressure line on the snowblower
has a RED cable tie on the hose end.
See loader’s operator’s manual for details on
identifying the correct pressurized hydraulic
coupler.
If you are operating the loader controls
correctly and the snowblower still does not
work, try switching the hydraulic couplers
around on the snowblower lead hoses. This
will effectively reverse the flow to the motor.

14
8. Make sure the hoses are properly routed to
fit your specific loader. If the hoses are not
routed correctly, hoses may get pinched or
rub on tires. Be sure to check the hose
routing through the full range of intended
motion of the attachment before operating it.
More than one routing may be acceptable
depending on the loader. Pick the routing
that best suits your loader.
IMPORTANT: Proper hose routing is the
responsibility of the owner and/or operator.
Pinched or stretched hoses are not
covered under warranty.
9. Connect the snowblower wire harness to
the loader wire harness receptacle.
10. Mounting is now complete and you are
ready to use the snowblower. Use reverse
order of above instructions to dismount the
snow blower from the loader.
11. Run the snowblower and check all
operational functions. Set-up assembly is
now complete.

OPERATING INSTRUCTIONS
1. Make sure area is free of obstructions that
might be picked up and thrown.
2. With the operator in the seat of the loader,
the seat belt fastened and the seat bar
lowered (if so equipped), start the engine.
Keep people away from
loader, attachment and discharge when in
use. This attachment sends objects flying
and has rotating parts. Never direct
discharge toward people –rocks and debris
can be thrown.
3. Rest the snowblower on the skid shoes (if
equipped) and/or cutting edge depending on
the application.
To improve stability, always
carry attachment low to the ground while
driving.
4. Make sure the skid shoes are set to the
position that will most benefit your
application.
5. If desired, the loader lift arms can be put in
the float position. (See your loader’s
operator’s manual.)
6. Activate the auxiliary hydraulic system to start
the snow blower turning. (See loader’s
operator’s manual.)
IMPORTANT: Engine must be at idle speed
when engaging auxiliary hydraulic system.
NOTE: Certain loaders may require special
wire harnesses to operate in high flow mode.
Others require the control switches to be
operated in a specific way. It may also be
necessary to switch the hose couplers around
to match your loader. (See loader’s
operator’s manual.)
IMPORTANT: Operating a low flow
snowblower in high flow mode will cause
serious damage and voids all warranties.

OPERATING INSTRUCTIONS
Hydraulic Chute Rotation and Deflection
All chute functions can be activated by the
steering lever switches on the loader (if loader is
fully equipped), or with the pistol grip control
harness.
FUNCTIONS ARE ACTIVATED AS FOLLOWS:
(A) Button 1 moves deflector UP.
(B) Button 2 moves deflector DOWN.
(C) Button 3 rotates chute LEFT.
(D) Button 4 rotates chute RIGHT.
(E) After you become familiar with the controls, direct
the chute towards an open space and away from
bystanders or obstructions. Operate the engine at
full throttle and start moving the loader forward into
the snow.
NOTE: For steering lever functions, refer to your
loader’s operator’s manual.
NOTE: The loader travel speed is determined by
the depth and density of the snow.
IMPORTANT: Do not operate the snowblower if
excessive vibration is present. Serious damage
can occur. Check auger and fan.
Cutting Edge Angle
The snowblower can be angled front to back by
rolling the mounting plate forward and back. This
allows for non-cutting (riding on skid shoes), neutral
position (shown), and aggressive cutting positions
depending on the conditions. The snowblower will
not cut when in the rolled back position and will cut
aggressively when rolled forward.
IMPORTANT: Do not operate the snowblower with
a rolled forward angle of more than 10 degrees (as
shown at right) or the endplates and auger may
strike the ground leading to excessive wear and
poor performance.

17
_____________________ROUTINE MAINTENANCE________________
Lower the snowblower to rest on the cutting edge, shut down the engine, relieve the
hydraulic pressure to the snowblower, wait for all motion to stop, and set park brake before leaving
the operator’s seat to perform service of any kind.
It is the operator’s responsibility to make daily inspections of the loader and attachment for damage, loose
bolts, fluid leaks, or anything else that could cause a potential service or safety problem. Preventive
maintenance is the easiest and least expensive type of maintenance.
IMPORTANT: Bolts and set screws can loosen after initial usage. After the first hour of operation check all
bolts and set screws.
Lubrication
Use No. 2 lithium base gun grease when
lubricating all snowblower grease fittings.
Add no more than 2 pumps of grease to the
bearing on the end of the auger after every 40
hours of operation.
Use clean engine oil to lubricate the chute
rotation chain after every 40 hours of
operation.

Lubrication (continued)
Grease the auger drive after every 48 hours of
operation.
NOTE: There are (2) grease fittings, one on
each side of the auger tube.
Grease the (3) chute roller guide bushings also
after every 4 hours of operation. (Not Pictured)
Hydraulic Relief Valve Adjustment
The fan is shear-protected by the loader
hydraulic system pressure relief valve. No
adjustments are required.
The auger is shear-protected by pressure relief
valve ‘A’ located in the hydraulic control
manifold on the rear of the snowblower, directly
above the fan motor.
NOTE: The auger relief valve is set at the
factory to assure the best performance in
average conditions. If the auger should stall too
easily, the relief valve can be adjusted as
follows:
1. Loosen the lock nut on valve ‘A’.
2. Turn the set screw one turn.
3. Tighten the lock nut.
4. If the auger still stalls, adjust the relief valve
again by repeating steps 1 through 3.
NOTE: Do not adjust the relief valve more than
one turn at a time or a total of more than 4
turns. If the auger still stalls, look for other
problems.

Auger Removal and Installation
1. Loosen the setscrew on the bearing
eccentric locking collar. Using a hammer
and punch, rotate the collar in the opposite
direction of auger travel.
NOTE: This frees up the bearing and
allows it to slide on the auger shaft.
2. Disconnect the tubelines from the auger
motor.
3. Remove the two bearing retaining bolts and
the four auger motor housing bolts.
NOTE: Pry the bearing flange
approximately 1/4” to the inside to allow
clearance for the auger to be removed.

4. Slide the auger straight forward and out of
the blower body.
5. The hydraulic motor and housing can now be
removed from the auger.
To install, use reverse procedure.
6. When everything is assembled and
tightened, with the exception of the bearing
locking collar, the auger should have from
1/4” to 1/2” endplay travel. Slide the auger
toward the auger motor until it bottoms out.
Then, tap it back in the opposite direction
approximately 1/16”.
7. Tighten the eccentric locking collar by using
a hammer and punch to rotate the collar in
the direction of the auger travel. Tighten the
setscrew.
NOTE: Grease the auger drive when
installing.
