Ski Wear Bars - Yamaha SR10ARLG Owner's Manual

5. Check headlight aim.
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 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-
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.

7. Adjust the headlight using the adjust-
ing screw on the backside of the head-
light using a 4 mm swivel socket and
long extension until correct aim is
obtained. Shut the engine off; then
disengage the brake lever lock.

Ski Wear Bars

The ski wear bar is a replaceable bar
attached to the underside of the ski. The
purpose of the wear bar is to assist in turn-
ing the snowmobile, to minimize ski wear,
and to maintain good steering control. If
the snowmobile is operated primarily in
deep snow, ski wear bar wear will be mini-
mal; however, if the snowmobile is oper-
ated on terrain where the snow cover is
minimal, the ski wear bar will wear faster.
To maintain positive steering characteris-
tics, Yamaha recommends that the ski wear
bars be checked before each use and
replaced if worn beyond 1/2 of the original
diameter. Ski wear bars are available from
an authorized Yamaha Snowmobile dealer.
Operating the snowmobile with
excessively worn ski wear bars may
result in a loss of steering control.
Removing (Single)
1. Using Front End Lift, elevate the
front of the snowmobile.
2. Remove the lock nuts securing the
wear bar to the ski.
