& Adjustments
Height Adjustment Lever
Effort
You may vary the amount of effort required to raise the blower head with the height adjustment lever.
This is done by lengthening or shortening the exposed threads on the two counterbalance spring
adjustment bolts. This balances the weight of the blower head against the springs, making the blower
head easier (or harder) to lift with the height adjustment lever.
However, if the blower head does not have enough weight, it may float above the surface of the snow.
For this reason, the recommend setting is to leave 75 mm (3 inches) of exposed thread. This setting
offers a good compromise between lifting effort and blower head weight.
To decrease lifting effort, increase the length of the
exposed threads by tightening the hex nut on each
bolt. To increase effort, loosen the hex nut on each
bolt. When making any adjustments, always make sure
the length of exposed thread is the same for both bolts.

Blower Head Angle
You may adjust the angle of the lower edge of the blower head. This adjustment will allow the blower
head to tilt forward or backward slightly.
the blower head to the push frame (see illustration at top of page 10). Hold the blower head at the desired
angle and tighten the four bolts securely. Disengage the lockout pin.
Lubrication
Chain
The drive belt operates
two chains inside the blower head. One chain runs the discharge fan and the
other drives the auger. Both chains must be lubricated on a regular basis for proper operation.
Always park the lawn tractor on a flat, level surface, engage the parking brake, and remove the ignition
key before attempting to lubricate any of the chains.
Auger Drive Chain:
Apply chain saw oil to the main auger sprocket
