ING ANY ADJUSTMENTS OR REPAIRS.
TO ADJUST SKID HEIGHT
This snow/ thrower is equipped with two height adjust­
ment skids, located on the outside of the auger housing
(See Fig 21) These skids elevate the front of the snow
thrower.
For normal hard surfaces, such as a paved driveway or
walk, adjust the skids as follows:
• Check tire pressure (14 to 17 pounds)
• Place the extra shear bolts supplied (found in parts
bag) under each end of the scraper bar near but not
under the skid
m Loosen the skid mounting nuts (See Fig 21), and
adjust the skids to allow the front of the snow
thrower to rest on the shear bolts Retighlen the
mounting nuts
• Set the skid on the other side at the same height
NOTE: For graveled 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
