TO ENGAGE DRIVE/AUGER

1.With the engine running near top speed, move shift lever into one of the FORWARD or REVERSE positions. Select a speed appropriate for the snow conditions that exist. Use the slower speeds until you are familiar with the operation of the snow thrower.

2.Squeeze the left hand auger drive clutch to engage auger.

3.While the left hand auger drive clutch is engaged, engage the right hand traction drive clutch.

NOTE: NEVER move shift lever without first releasing the drive clutch.

TIRE CHAINS (OPTIONAL):

Use tire chains when extra traction is necessary.

OPERATING TIPS

NOTE: Allow the engine to warm up for a few minutes as the engine will not develop full power until it reaches operating temperature.

WARNING: Temperature of muffler and surrounding areas may exceed 150oF. Avoid these areas.

•For most efficient snow removal, remove snow immediately after it falls.

•Discharge snow downwind whenever possible. Slightly overlap each previous swath.

•Set the skid shoes 1/4" below the scraper bar for normal usage. The skid shoes may be adjusted upward for hard-packed snow. Adjust downward when using on gravel or crushed rock.

•Be certain to follow the precautions listed under ‘‘To Stop Engine’’ in previous column to prevent possible freeze-up.

•Clean the snow thrower thoroughly after each use.

SECTION 8: ADJUSTMENTS

WARNING: Never attempt to clean chute or make any adjustments while engine is running.

ADJUSTING CHUTE

You can control the distance that snow is thrown by adjusting the angle of the chute assembly. The sharper the angle, the shorter the distance snow is thrown.

1.To adjust the chute, loosen the hand knob. See Figure 25.

2.Pivot the top of the chute assembly to the position desired.

ADJUSTING SKID SHOE

The space between the shave plate and the ground can be adjusted by adjusting the skid shoe. Slide the skid shoe upwards and lower the housing to remove snow close to the ground. Slide skid shoe downwards and raise the housing to remove snow from uneven ground like gravel. For more details, refer to Adjusting the Skid Shoes in section 5.

ADJUSTING TRACTION DRIVE CLUTCH

Refer to the Final Adjustments section on page 10 for instructions to adjust the traction drive clutch. If you are not sure whether you have been able to adjust the traction drive clutch properly, check as follows.

1.Drain the gasoline from the snow thrower or put a plastic film under the gas cap if the snow thrower has already been operated. Tip the snow thrower forward onto the auger housing.

2.Remove the frame cover underneath the snow thrower by removing the six self-tapping screws.

3.With the traction drive clutch released, check if there is clearance between the friction wheel and the drive plate in all positions of the shift lever. For correct adjustment there has to be enough clearance.

4.With the traction drive clutch engaged, check if the friction wheel is contacting the drive plate. See Figure 26.
