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 1/8 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 car-
riage bolts and nuts, insuring that the scraper bar is parallel
with the working surface.
4. For extended operation, the scraper bar may be reversed. 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) under
scraper bar near but not under skid.
2. Loosen skid mounting nuts (Figure 31) 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.
