6.12 Adjusting the Auger/Impeller Drive Belt
Service Interval:
After the first hour
Before each use or daily
Operating the snow thrower with an auger/impeller
drive belt that slips decreases the snow throwing
performance and damages the belt. Check the
auger/impeller drive belt for the proper tension after
the first operating hour, then check and adjust the belt
when necessary.
Improperly adjusting the auger/impeller may cause it
to turn when disengaged. A rotating auger/impeller
can cut off or injure fingers, hands, or feet.
z
Keep your face, hands, feet, and any other part of
your body or clothing away from concealed,
moving, or rotating parts.
z
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.

Check and adjust the belt as instructed in 2.4.3
and 2.4.4 in Setup.
6.12.2
Insert the ignition key and start the engine.

6.14 Replacing the Safety Pin
