safety mechanism and designed to break under high load or impact to protect
the auger drive system from damage.
Replacement shear pins and nylon locknuts are provided with your snowblower.
1. Turn off the engine, disengage the control
handles and wait for all moving parts to
come to a complete stop.
2. Remove any remnants of the broken shear
pin. It may be necessary to unscrew the
nut from the broken shear pin and drive
out the broken pin.
3. Insert a new shear pin through the hole in
the auger shaft and tighten using the shear
pin nylon locknut. Do not over-tighten the nylon locknut.
DRIVE SPEED CONTROL CABLE ADJUSTMENT
WARNING! Entanglement Hazard – Use caution when performing the speed
control cable adjustment.
The speed control lever is connected to two cables that work in tandem to
control machine speed and direction. As the speed control lever is moved from
forward to reverse gears, one cable is pulled and one is pushed (Fig. 10).
Depending on if the cable setting towards
forward or reverse, adjustment of the
cables will vary.
To adjust the cables, one cable should be
moved up and the other down equally in
their respective brackets until there is a
positive direction change when the lever is
shifted between F1 and R1. The middle
position between these two settings is
neutral (there is no actual neutral ‘notched’ position on the control panel).
1. With the engine running engage the drive control handle and move the
speed control lever between 1 and R1 to determine which way the cables
need to be adjusted. Release the drive control handle when shifting
between gears.
