the belt is on the inside of the idler pulley and the belt
guide (Fig. 24).
19. Adjust the belt guide so that there is 1/8 inch
(3 millimeters) of clearance between the auger/impeller
drive belt and the guide, and secure the belt guide when
the auger/impeller drive belt is tight.
20. Check the auger/impeller drive linkage and adjust it if

Adjusting the Auger/Impeller
Drive Belt
Operating the snowthrower with an auger/impeller drive
belt that slips decreases the snowthrowing performance and
damages the belt. Check the auger/impeller drive belt for
the proper tension after the first operating hour, after every
five operating hours thereafter. Adjust the belt when
necessary.
Danger
Improperly adjusting the auger/impeller may
cause it to turn when disengaged. A rotating auger
or impeller can cut off or injure fingers, hands, or
feet.
Keep your face, hands, feet, and any other part
of your body or clothing away from concealed,
moving, or rotating parts.
Ensure that the impeller brake arm clearance is
maintained.
Do not adjust the auger/impeller drive belt too
tight because it may cause the auger/impeller to
turn when the control lever is in the Disengaged
position. If this occurs, decrease the belt tension.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 15).
3. Check and adjust the belt as instructed in steps 4
through 7 of Installing the Auger/Impeller Drive
Control Linkage on page 10.
