Track/Track Studs; Paddle Track (On Equipped Models); Reverse Operation - Yamaha SXV4NP Operator's Manual

Track/Track Studs

Accelerated wear strip and track clip
wear caused by operating on ice or hard-
packed snow conditions is NOT covered
under Yamaha warranty policy.

NOTE: If regularly operating on ice
or hard-packed snow conditions,
Performance Wear Strips may be
installed at the expense of the snow-
mobile owner.
In general, track life will be shortened
when studs are installed. Drilling stud
holes into the drive track will cut the
internal fibers weakening the track.
Avoid spinning the drive track. Studs
may catch on an object and pull out of the
track leaving tears and damage around
the already weakened area. To minimize
possible damage, consult your stud man-
ufacturer for installation and stud pattern
recommendations. Yamaha does not rec-
ommend studding a track.
Paddle Track (on
equipped models)
Some snowmobiles are equipped with a
Power Claw-style track specifically
designed for use in powder snow riding
conditions. When the Power Claw track
is operated in hard-packed snow condi-
tions, it will run slightly slower than a
standard track and it will accelerate wear
strip wear. To decrease the amount of
wear strip wear, slower speeds must be
maintained and ice scratchers utilized
when operating on hard-packed trails.
Accelerated wear strip wear caused by
operating a Power Claw track in hard-
packed snow conditions is NOT covered
under Yamaha warranty policy. Never
exceed the maximum sustained speeds for
the specific deep-lug tracks:
Track Lug
2.6 in. (66 mm)
3.0 in. (76 mm)

NOTE: If operating on ice or hard-
packed snow conditions, it is recom-
mended that Ice Scratchers be used
to reduce wear strip wear and engine
overheating.

Speed

Reverse Operation

The engine reverse function offers the oper-
ator the convenience of being able to back
up the snowmobile rather than having to
turn the snowmobile around by hand. This
feature, under most situations, should not
be used to free a stuck snowmobile as it will
tend to dig the skis deeper into the snow.
Always use minimal speed when operating
in reverse.
Shifting Into Reverse
1. Always warm up the engine for 2-3
minutes prior to shifting into reverse.
The reverse function is canceled when
engine temperature is below or above
normal operating range.
2. Shift only with the engine at idle RPM
and the snowmobile completely stopped.
3. If attempting to shift into reverse at too
high engine RPM (above 3000 RPM),
the reverse function will be canceled.
This indicates the reverse switch button
was pressed at too high RPM. The oper-
ator must reduce engine RPM below
3000 and press the button a second time.
4. Upon pressing the reverse switch but-
ton, the reverse function will make up
to three attempts to engage into
reverse. If the function is not com-
pleted after the third attempt, the
engine will shut down.
