Wheel pin
Do not remove the wheel pins with the snowblower on a slope. The
snowblower might move unintentionally, causing serious injury.
Before removing the wheel pins, place the snowblower on a level
surface. Stop the rotating parts, stop the engine, and remove the
engine switch key.
Remove the cotter pins and wheel pins from the rear right and left
wheels. This allows the track to rotate freely so the operator can move
the snowblower if the motor malfunctions. Use a new cotter pin when
replacing the wheel pin.
