AUGER HOUSING HEIGHT ADJUSTMENT
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 one-eighth of an
inch (3 mm) between the scraper bar and the sidewalk or
area to be cleaned.
To adjust the scraper bar, proceed as follows:
1.
Position the snowthrower on a level surface.
2.
Loosen the carriage bolts and nuts securing the scraper
bar to the auger housing.
3.
Adjust the scraper bar to the proper position. Tighten the
carriage bolts and nuts, insuring that the scraper bar is
parallel with the working surface.
4.
For extended operation, the scraper bar may be re-
versed. If the scraper bar must be replaced because of
wear, remove the carriage bolts and nuts and install a
new scraper bar.
TO ADJUST SKID HEIGHT
This snowthrower is equipped with two height adjust skids,
secured to the outside of the auger housing. These elevate
the front of the snowthrower.
When removing snow from a hard surface area such as a
paved driveway or walk, adjust the skids up to bring the front
of the snowthrower down.
When removing snow from rock or uneven construction,
raise the front of the snowthrower by moving the skids down.
This will help to prevent rocks and other debris from being
picked up and thrown by the augers.
To adjust skids, proceed as follows:
1.
Place a block (equal to height from ground desired) un-
der scraper bar near but not under skid.
2.
Loosen skid mounting nuts (Figure 28) and push the skid
down until it touches the ground. Retighten mounting
nuts.
3.
Set skid on other side at same height.
NOTE: Make sure that snowthrower is set at same height
on both sides.
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 dam-
age or damage to the snowthrower.
