Air filter
Always check that no snow is under the air filter element.
Remove the air filter case cover and take out the air filter
element. If there is any snow under the air filter element,
remove the snow. Then install the air filter element
beneath the holding guides on the case and install the air
filter case cover.
NOTE:@ After riding the snowmobile, make sure that there is no
snow under the air filter element.

Break-in
There is never a more important period in the life of your
engine than the period between 0 and 500 km (300 mi).
For this reason, you should read the following material
carefully.
Since the engine is brand new, do not put an excessive
load on it for the first 500 km (300 mi). The various parts
in the engine wear and polish themselves to the correct
operating clearances. During this period, prolonged full-
throttle operation or any condition that might result in
engine overheating...

Riding your snowmobile
Getting to know your snowmobile
A snowmobile is a rider active vehicle, and
your riding position and your balance are
the two basic factors of maneuvering your
snowmobile. 
Riding your snowmobile requires skills
acquired through practice over a period of
time. Take the time to learn the basic tech-
niques well before attempting more difficult
maneuvers. 
Riding your new snowmobile can be a very
enjoyable activity, providing you with hours
of pleasure. However, it is...

Tu r n i n g
For most snow surfaces, “body English” is
the key to turning.
As you approach a curve, slow down and
begin to turn the handlebar in the desired
direction. As you do so, put your weight on
the running board to the inside of the turn
and lean your upper body into the turn.
This procedure should be practiced at low
speed many times, in a large flat area with
no obstacles. Once you have learned this
technique, you should be able to perform it
at higher speeds or in tighter curves. Lean

Riding downhill
When riding downhill, keep speed to a min-
imum. It is important to apply just enough
throttle to keep the clutch engaged while
descending the hill. This will allow you to
use engine compression to help slow the
snowmobile, and to keep the snowmobile
from rolling freely down the hill. Also apply
the brake frequently, with light pressure.
WARNING@ 
Use extra caution when applying the
brake during a descent. Excessive
braking will cause the drive track to
lock, causing a loss of...

Hard-packed snow
It can be more difficult to negotiate on
hard-packed snow as both the skis and
drive track do not have as much traction as
when the snowmobile is operated on fresh
snow. Avoid rapid acceleration, turning, or
braking.
Operation on surfaces other than
snow or ice
Operation of your snowmobile on surfaces
other than snow or ice should be avoided.
Operation under such conditions will dam-
age or result in rapid wear of the ski run-
ners, drive track, slide runners, and drive
sprockets....

Maximizing drive track life
Recommendations
Track tension
During initial break-in, the new drive track will tend to
stretch quickly as the track settles. Be sure to correct the
track tension and alignment frequently. (See pages
8-28–8-30 for adjustment procedures.) A loose track can
slip (ratchet), derail or catch on suspension parts caus-
ing severe damage. Do not overtighten the drive track,
otherwise it may increase the friction between the track
and the slide runners, resulting in the...

Strap
For RX10M/RX10MS
The strap 
1 should be used only by experienced opera-
tors to assist them when traverse (side-hill) riding.
WARNING@ 
Improper use of the strap on the handlebar can
result in severe injury or death. 

Use the strap only as an operator grip point when
needed to shift weight uphill to maintain balance
during traverse (side-hill) riding. Only experi-
enced operators should traverse slopes steep
enough to require strap use. 

Keep the right hand on the right handlebar...
