Operation

IMPORTANT NOTE

Always raise the snowthrower before turning or backing up, to prevent damage to the unit.

Transporting

1. Disengage the electric clutch and then raise the snowthrower.

2. Adjust ground speed according to surface conditions.

3. Select a low ground speed when transporting on a slippery surface.

Engine & Ground Speed Selection

Always run the engine at full throttle.

Normally, a slow ground speed is best for throwing snow.

The deeper or heavier the snow, the slower the recommended ground speed.

Starting & Stopping

1. Start the tractor engine. Set engine throttle at full speed.

2. Lower the snowthrower.

3. Engage the electric clutch switch. Snowthrower auger should rotate. Disengage the electric clutch switch.

Snowthrower auger should stop.

Snow Removal Suggestions

• Determine the best snow removal pattern before beginning.

• Wind direction is an important factor to consider.

Rotate the spout to discharge snow downwind.

• Plan the pattern so that you avoid throwing snow on cleared areas and on yourself as you are operating.

• When land contour permits, it is best to travel in the longest direction to minimize turning.

• In very deep or heavy snow, it may be necessary to make the first pass with snowthrower partially raised, backing up every few feet and lowering the snowthrower to clear the snow left on the surface.

Also, it may be necessary to slice off less than the full width of the auger or reduce ground speed.

• If snow stops flowing freely from the spout, back away until the snowthrower clears itself.

DANGER

If the auger stalls or the chute plugs, DISENGAGE

THE ELECTRIC CLUTCH, STOP THE ENGINE AND

REMOVE THE KEY. SET THE PARKING BRAKE.

WAIT FOR MOVING PARTS TO STOP. Remove the foreign object or clear the spout with a piece of wood before restarting the engine. Never place hands into auger housing or spout to clear jammed object. Auger may rotate when object is removed.

WARNING

If auger does not start and stop when engaging/disengaging electric clutch, see your authorized dealer. Under no circumstances should you attempt to defeat the safety system.

4. Select the proper ground speed.

5. To stop the tractor, depress the clutch/brake pedal.

To stop the snowthrower, disengage the electric clutch. Before leaving the seat, stop the engine, disengage the electric clutch, set the parking brake, remove the key, and wait for all moving parts to stop.
