SERVICE AND ADJUSTMENTS
A CAUTION: Always disconnect the
spark plug wire and tie back away from
the plug before making any adjustments
or repairs.
TO ADJUST SKID HEIGHT
This snow thrower is equipped with two
height adjustment skids, located on the out­
side of the auger housing (see figure be­
low), These skids elevate the front of the
snow thrower.
Auger Housing
Height Adjust Skids
Skid Mounting Nuts
For normal hard surfaces, adjust the skids
as follows;
• Check tire pressure (14 pounds). See
side of tire for maximum inflation. Do not
exceed maximum pressure on side of
tire.
• Place the extra shear bolts supplied
(found in parts bag) under each end of
the scraper bar near but not under the
skid.
• Loosen the skid mounting nuts (see fig­
ure above) and adjust the skids up to
bring the front of the snow thrower down.
• Re-tighten the mounting nuts.
• Set the skid on the other side at the same
height.
For rocky or uneven surfaces, adjust the
skids as follows:
• Raise the front of the snow thrower by
moving the skids down. This will help pre­
vent rocks and other debris from being
picked up and thrown by the auger.
NOTE; Be sure that snow thrower is set at
same height on both sides.
TO ADJUST SCRAPER BAR
After considerable use, the metal scraper
bar will have a definite wear pattern. The
scraper bar in conjunction with the skids
should always be adjusted to allow 1/8" be­
tween the scraper bar and the sidewalk or
area to be cleaned. The scraper bar may
have to be returned to its original lower set­
ting to maintain the original performance
level. To adjust:
• Position the snow thrower on a level sur­
face.
• Make sure both tires are equally inflated.
• Loosen the carriage bolts and nuts secur­
ing the scraper bar to the auger housing.
• Adjust the scraper bar to the proper posi­
tion.
• Tighten the carriage bolts and nuts, mak­
ing sure that the scraper bar is parallel
with the working surface.
• For extended operation, the scraper bar
may be reversed. If the scraper bar must
be replaced due to wear, remove the car­
riage bolts and nuts and install a new
scraper bar.
CAUTION: Be certain to maintain
proper ground clearance for your par­
ticular area to be cleared. Objects such as
gravel, rocks or other debris, if struck by the
impeller, may be thrown with sufficient force
to cause personal injury, property damage
or damage to the snow thrower.
TO ADJUST THE CLUTCH CONTROL
CABLES
Periodic adjustment of the cables may be
required due to normal stretch and wear on
the belts. To check for correct adjustment,
disconnect "Z" Fitting at clutch lever, move
clutch lever to the full fonward position, just
contacting the plastic bumper. The control
cables are correctly adjusted when the cen­
ter of the "Z" fitting is between the center
and top of the hole and there is no droop in
the cable (see figure below), if adjustment is
necessary:
