SPARK PLUG WIRE AND TIE BACK AWAY
FROM THE PLUG BEFORE MAKING 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.
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 12.
® Place extra shear bolts 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. 20) and
push the skids down until they touch the ground.
Retighten the 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:
If the skids are at the maximum height, the weight
transfer system will not work,
