Adjusting Headlight Aim - Arctic Cat Sno Pro 120 2011 Service Manual

6. Check headlight aim (see Adjusting Headlight Aim
in this sub-section).
! WARNING
Do not operate the snowmobile unless headlight beam
is adjusted properly. An incorrectly adjusted beam will
not provide the operator the optimum amount of light.

Adjusting Headlight Aim

The headlight can be adjusted for vertical aim of the
HIGH/LOW beam. The geometric center of HIGH beam
zone is to be used for vertical aiming.
1. Position the snowmobile on a level floor so the head-
light is approximately 8 m (25 ft) from an aiming
surface (wall or similar surface).
 NOTE: There should be an "average" operating load
on the snowmobile 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.
8-44
4. Make a vertical mark intersecting the horizontal
mark on the aiming surface directly in front of the
headlight.
5. Start the engine. Select the headlight dimmer switch
HIGH beam position. 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 5 cm (2 in.) below the horizontal mark on the
aiming surface.
7. Adjust the headlight housing mounting screws (on
the 3-bulb models) or the console adjustment knobs
(on the 4-bulb models) until correct aim is obtained.
Shut the engine off.
