SERVICE AND ADJUSTMENT
A WARNING: Always discon­
nect the spark plug wire and
place it where it cannot
make contact with spark plug to pre­
vent accidental starting when mak­
ing any adjustments or repairs.
TO ADJUST SKID HEIGHT
This snow thrower is equipped with two
height adjustment skids, located on
the outside of the auger housing. See
Figure 19.
These skids elevate the front of the
snow thrower.
For normal hard surfaces, such as a
paved driveway or walk, adjust the
skids as follows.
1. Position the snow thrower on a level
surface.
2. Make sure both tires are equally in­
flated. Proper tire pressure is 14 to
17 PSI. See side of tire for maxi­
mum inflation. Do not exceed side­
wall maximum pressure on tire.
3. Place the extra shear bolts supplied
(found in parts bag) under each
end of the scraper bar next to the
adjustable skids.
4. Loosen the mounting nuts that hold
the adjustable skids. To bring the
front of the snow thrower down,
raise the adjustable skids. Tighten
the mounting nuts. See Figure 19.
NOTE: For rocky or uneven surfaces,
raise the front of the snow thrower by
moving the skids down.
A WARNING: Be certain to
maintain proper ground
clearance for your particular
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 SCRAPER BAR
After considerable use, the metal scrap­
er bar will have a definite wear pattern.
The scraper bar in conjunction with the
skids should always be adjusted to al­
low 1/8” between the scraper bar and
the sidewalk or area to be cleaned.
1. Position the snow thrower on a level
surface.
2. Make sure both tires are equally in­
flated. Proper tire pressure is 14 to
17 PSI. See side of tire for maxi­
mum inflation. Do not exceed side­
wall maximum pressure on tire.
3. Loosen the carriage bolts and nuts
securing the scraper bar to the au­
ger housing.
4. Adjust the scraper bar to the proper
position.
5. Tighten the carriage bolts and nuts,
making sure that the scraper bar is
parallel with the working surface.
6. For extended operation, the scraper
bar may be reversed. If the scraper
bar must be replaced due to wear,
remove the carriage bolts and nuts
and install a new scraper bar.
