SERVICE AND ADJUSTMENTS
A
CAUTION: ALWAYS DISCONNECT THE
SPARK PLUG WIRE AND TIE BACK

ING ANY ADJUSTMENTS OR REPAIRS.
TO ADJUST SKIDS HEIGHT
This snow thrower is equipped with two height adjust­
ment skids, located on the outside of the auger housing
(See Fig. 23). These skids "elevate the front of the snow
thrower
For normal hard surfaces, adjust the skids as follows;
® Make sure the snow thrower is on a hard, level
surface and the weight transfer system lever is
released See page 13
® Place extra shear bolls supplied (found in parts
bag) under each end of the scraper bar near but not
under the skids.
® Loosen the skid mounting nuts (See Fig 23) and
push the skids down until they touch the ground.
Retlghtenthe mounting nuts,
For rocky or uneven surfaces, raise the front of the snow
thrower by moving the skids down This will help prevent
rocks and other debris from being picked up and thrown
by the auger
NOTE: Ifthe skids are atthe maximum height, the weight
transfer system wiii not work.
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 aiways be adjusted to allow 1/8”
between the scraper bar and the sidewalk or area to be
cleaned.
* Position the snow thrower on a level surface
* Loosen the carriage bolts and nuts securing the
scraper bar to the auger housing,
® Adjust the scraper bar to the proper position
® Tighten the carriage bolts and nuts, making sure that
the scraper bar is parallel with the working surface.

reversed it the scraper bar must be replaced due
to wear, remove the carriage bolts and nuts and
install a new scraper bar.
