WARNING
Do not operate the snowmobile if you find
damage to the drive track, or if it has been
maladjusted. Drive track damage or failure
could result in loss of braking ability and
snowmobile control, which could cause
an accident.
Check the drive track alignment and deflec-
tion, and check the track for wear and dam-
age.
Adjust or replace if necessary. (See the fol-
lowing section for more details.)
Checking the drive track alignment
1. Lift the rear of the snowmobile onto a suit-
able stand to raise the drive track off the
ground.
2. Start the engine and rotate the drive track
one or two turns. Stop the engine.
3. Check the drive track alignment with the
slide runners. If the alignment is incorrect,
adjust the drive track.
