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 maxi-
mum sidewall 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 16.
NOTE: For rocky or uneven surfaces,
raise the front of the snow thrower by
moving the skids down.
_lb 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.
