Adjusting Headlight Aim
The headlight can be adjusted for vertical
aim of the HIGH/LOW beam. The geo-
metric center of HIGH beam zone is to be
used for vertical aiming.
1. Position the snowmobile on a level
floor so the headlight is approxi-
mately 8 m (25 ft) from an aiming
surface (wall or similar surface).

NOTE: There should be an "aver-
Taillight
age" operating load on the snow-
mobile when adjusting headlight
aim.
2. Measure the distance from the floor
to midpoint of the headlight.

3. Using the measurement obtained in
step 2, make a horizontal mark on
the aiming surface.
4. Make a vertical mark which inter-
sects the horizontal mark on the aim-
ing surface directly in front of the
headlight.
5. Engage the brake lever lock and start
the engine. Move the headlight dim-
mer switch to the HIGH beam posi-
tion. DO NOT USE LOW BEAM.
6. Observe the headlight beam aim.
Proper aim is when the most intense
beam is centered on the vertical mark
50 mm (2 in.) below the horizontal
mark on the aiming surface.
