• If the extension spring is already found in the
middle position on the idler bracket, move it from
the middle position to the high position.
• Reattach the belt cover with the five hex screws
removed earlier.
Shave Plate
• To check the adjustment of the shave plate, place
the unit on a level surface. The wheels, shave plate
and augers should all contact the level surface.
Note that if the shave plate is adjusted too high,
snow may blow under the housing. If the shave
plate wears out excessively, or the unit will not self-
propel, the shave plate may be adjusted too low.
NOTE: On new units or units with a new shave plate
installed, the augers may be slightly off the ground.
• To adjust, tip the snow thrower back so that it rests
on the handle. Loosen the lock nuts from the
carriage bolts which secure the shave plate to the
housing. See Figure 9.
Carriage Bolts
• Move the shave plate to desired position and
retighten the nuts and bolts. Make certain all four
nuts are securely tightened.
Engine
Refer to the Tecumseh Engines manual packed with
the snow thrower for detailed instructions regarding all
engine-related maintenance.
