below.
Track Alignment
WARNING
Before checking track alignment,
ensure that the track is free of all
particles which could be thrown
out while track is rotating. Keep
hands, tools, feet and clothing
clear of track. Always lift the snow-
mobile on a wide-base stand with
a rear deflector panel. Ensure no
one is standing in close proximity
to the snowmobile, especially at
the rear of the track. Never rotate
track at high speed.
Centrifugal force could cause de-
bris, damaged or loose studs,
pieces of torn track, or an en-
tire severed track to be violently
thrown backwards out of the tun-
nel with tremendous force.
Start the engine and accelerate slightly
so that track barely turns. This must be
done in a short period of time (about 5
seconds).
Check that the track is well centered;
equal distance on both sides between
edges of track guides and slider shoes.
