Adjust the snow discharge chute to avoid hitting the operator,
bystanders, windows, and other objects with thrown snow. Stay
clear of the snow discharge chute while the engine is running.
To move from one place to another, or to change direction, use the
drive clutch lever. Using the auger clutch switch will cause the
snowblowing mechanism to rotate, possibly resulting in equipment
damage or personal injury.
Be sure to set the main shift lever in SLOW RANGE when removing
the snow.
Clearing snow from snow discharge chute
If the snow discharge chute becomes clogged, stop the engine,
remove the engine switch key, and use a snow drop bar or a
wooden stick to unclog the snow discharge chute.
Never put your hand into the snow discharge chute while the
engine is running; serious personal injury could result.
1. If the snow discharge chute is clogged with snow during operation,
remove the snow from it using the snow drop bar.
2. After clearing the snow, clean and return the snow drop bar to its
original position.
