• Check clutch control cable adjustment,
see page 17.
• Reconnect spark plug wire.
TRACTION DRIVE BELT
If your snow thrower will not move forward,
check the traction drive belt (see second
figure on page 18) for wear (Check other
causes also in the Trouble Shooting Points
section). If the traction drive belt needs to
be replaced, proceed as follows:
• Disconnect the spark plug wire.
• Remove the belt cover (see last figure on
page 18).
• Loosen the belt guides and pull away
from engine drive pulley (see first figure).
• Loosen nut on auger idler and pull auger
idler pulley away from belt. Note location
of idler pulley for later re-installation.
• Remove auger drive belt from engine pul­
ley.
• Pull the idler pulley away from the drive
belt, allowing belt to be positioned onto
engine pulley.
• Release idler pulley. Ensure idler pulley is
properly engaged with belt.
• Reinstall auger drive belt.
• Adjust belt guides (see To Adjust The
Belt Guides paragraph below).
• Adjust idler on auger belt.
• Reinstall the belt cover.
• Reconnect the spark plug wire.
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 18).
• 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.
• If adjustment is necessary, loosen the
belt guide mounting bolts. Move the belt
guides to the correct position. Tighten the
mounting bolts.
• Reinstall the belt cover.
• Reconnect the spark plug wire.

TO ADJUST THE FRICTION WHEEL
If the snow thrower will not move fonward,
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 page 20). If the friction
wheel is not worn, check the adjustment, 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).

• Position the shifter lever in first (1) gear.
• Note the position of the friction wheel on
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
