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 150
degrees Fahrenheit. Avoid these areas.
1. For most efficient snow removal, remove snow
immediately after it falls.
2. Discharge snow downwind whenever possible.
Slightly overlap each previous swath.
3. 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.
4. Be certain to follow the precautions listed under
‘‘To Stop Engine’’ to prevent possible freeze-up.
5. 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. Refer to label in
Figure 1 in safety section.
CHUTE ASSEMBLY ADJUSTMENT
The distance snow is thrown can be adjusted by
adjusting the angle of the chute assembly. The
sharper the angle, the shorter the distance snow is
thrown. See Figure 20.
To adjust chute assembly, loosen the hand knob.
Pivot the top of the chute assembly to position
desired. Retighten the hand knob.

pensate for differences in fuel, temperature, altitude
