Making Adjustments - Yard-Man 31BH763G401 Operator's Manual

Operating Tips
NOTE: Allow the engine to warm up for a few minutes.
The engine will not develop full power until it reaches
operating temperature.
WARNING: The temperature of the muffler
and the surrounding areas may exceed
°
150 F. Avoid these areas.
• For the most efficient snow removal, remove snow
immediately after it falls.
SECTION 5: MAKING ADJUSTMENT
WARNING: NEVER attempt to make any
adjustments while the engine is running,
except where specified in the operator's
manual.
Chute Assembly
The distance snow is thrown can be adjusted by
changing the angle of the chute assembly. To do so,
stop the engine by removing the ignition key and loosen
the plastic wing knobs found on either side of the
discharge chute. Pivot the chute upward or downward
before re-tightening the wing knobs.
Auger Control

• To check the adjustment of the traction control
clutch and shift lever, proceed as follows:
• With the engine off, move the shift lever all the way

the traction control grip. The wheels should stop
turning.
• Now release the traction control grip and push the
unit again.
• Move the shift lever back to the fast reverse
position then all the way forward again. There
should be no resistance in the shift lever, and the
wheels should keep turning.
• If you have resistance when moving the shift lever
or the wheels stop when they should not, loosen
the jam nut on the traction control cable and
unthread the cable one turn.
• If the wheels do not stop when you engage the
traction control clutch grip, loosen the jam nut on
• Discharge the snow downwind whenever possible.
• Slightly overlap each previous path.
• Set the skid shoes 1/4" below the shave plate for
normal usage. The skid shoes may be adjusted
upward (to lower the shave plate) for hard-packed
snow. Adjust downward (to raise the shave plate)
when using on gravel or crushed rock.
• Be certain to follow the precautions found in the To
Stop Engine section to prevent possible freeze-up.
• Clean the snow thrower thoroughly after each use.

snow thrower's tank, or place a piece of
plastic film under the gas cap to avoid
spillage BEFORE making the adjustment.
