If adjustment is necessary, loosen the
belt guide mounting bolt. Move the belt
guide to the correct position and tighten
the mounting bolt.
Reinstall the belt cover.
Reconnect the spark plug wire.
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 page 21). 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
