TO ADJUST SKID HEIGHT
TTiis snovi? thrower is equipped with two height adjust­
ment skids, located on the outside of the auger housing

follows:
® Make sure the weight transfer system is released
by holding upper handle firmly and pushing down
weight transfer pedal with the ball of your foot.

bag} under each end of the scraper bar near but not
under the skid.
® Loosen the skid mounting nuts (See Fig, 20) and
push the skid down until it touches the ground.
Reiighten the mounting nuts
® Set the skid on the other side at same height.
For rocky or uneven suriaces, raise the front of the snow
thrower by moving the skids down further. This will help
prevent rocks and other debris from being picked up and
thrown by the auger
NOTE: [f the skids are at the maximum height, the weight
transfer system will not work.
