TO ADJUST THE BELT GUIDES
After you replace the traction or auger drive
belt, you need to adjust one or both of the
belt guides. Proceed as follows:
• Disconnect the spark plug wire.
• Remove the belt cover (See last figure on
page 19).
• Engage the auger drive clutch lever.
• Measure the distance between the belt
guides and the belt (See next figure). The
distance should be 3/32" for each guide.

the disc drive plate. The right outer side of
the disc drive plate should be 3" from the
center of the friction wheel (See figure be-

guide mounting bolts. Move the belt
guides to the correct position. Tighten the
mounting bolts.

TO ADJUST THE FRICTION WHEEL
If the snow thrower will not move forward,
you need to check the traction drive belt, the
traction drive cable or the friction wheel. If
the friction wheel is damaged, it will need to
be replaced (see the To Replace Friction
Wheel paragraph on pages 20 and 21). If
the friction wheel is not worn, check the ad-
justment, as follows:
• Disconnect the spark plug wire.
• Drain the gasoline from the gas tank.
• Stand snow thrower on the auger housing
end.
• Remove the bottom panel (see figure be-
low).
