Checking/Adjusting Headlight Aim
The headlights can be adjusted vertically and horizon-
tally. The geometric center of the HIGH beam light zone
is to be used for vertical and horizontal aiming.
1. Position the ATV on a level floor so the headlights
are approximately 6.1 m (20 ft) from an aiming sur-
face (wall or similar aiming surface).
0748-548

NOTE: There should be an average operating load
on the ATV when adjusting the headlight aim.
2. Measure the distance from the floor to the mid-point
of each headlight.
3. Using the measurements obtained in step 2, make
horizontal marks on the aiming surface.
4. Make vertical marks which intersect the horizontal
marks on the aiming surface directly in front of the
headlights.
5. Switch on the lights. Make sure the HIGH beam is
on. DO NOT USE LOW BEAM.
6. Observe each headlight beam aim. Proper aim is
when the most intense beam is centered on the verti-
cal mark 5 cm (2 in.) below the horizontal mark on
the aiming surface.
7. To adjust the headlights, loosen the adjustment knob.
After proper adjustment is achieved, tighten the knob
securely.
