Start-up and Operation Instructions
The hydraulic system of the snowblower is configured so that the fan motor is prevented from
stalling in a snow overload condition. A significant increase in fan loading increases the hydraulic
pressure drop across the fan motor, which in turn diverts flow away from the auger motor, thereby
reducing/stopping further fan loading and simultaneously providing more power to clear the fan.
When the fan clears and pressure returns to normal, flow returns to auger so normal operation can
proceed. The fan should not require unclogging, other than a situation where a rock or other hard
material becomes jammed in it.
Depth of cut at ground level can be controlled both by tilting the snowblower forward/rearward
and by using one of the three desired height sets of the skids. If it is preferred that the skids not be
used to control cut depth, a fourth set of holes are provided (skid in highest position) but use is not
recommended due to the premature cutting edge wear that may result. Snowblower should not be
operated with skids completely removed as damage to housing may result.
Each season, the chute rotator chain should be lubricated and checked for excess slack (chain can
be tightened by taking advantage of the mounting motor slots). Also, the right hand auger bearing
should be greased each season and every 10 hours of use thereafter. Run the snowblower at low
RPM to check all operation before blowing snow. Periodically check bolt tightnesses, particularly
the fan motor and auger motor housing bolts.
Always disengage hydraulics and shut off the power unit before doing any servicing or
unplugging. When replacing bearings or tightening a loose bearing collar, always tighten collar in
the direction of shaft rotation using a center punch or a similar tool.
If the fan should need to be removed, use an appropriate two jaw puller using the slots provided
in the fan and fan housing backplate. Prior to reassembly, tapered surfaces need to be completely
clean (no paint or rust) with a coating of anti-seize compound applied. Castle nut must be torqued
to at least 140 ft-lbs and aligned such that the nut can then be retained with new cotter-pin.
If auger motor is removed from auger, its surfaces should also be cleaned and coated with anti-
seize compound before re-assembly.
CAUTION
The locking pins must extend through the holes in the attachment
when mounting the snowblower to an implement. Levers must be
fully down and locked. Failure to secure pins can allow attachment
to come off and cause injury or death.
