SPECIAL OPERATIONS
Engine overheating
NOTE: (4-tec only) If the buzzer ac-
tivates during high temperatures,
turn off the engine by engine cut-off
switch, if this is not applied and the
temperature continues to increase the
engine will shut down by EMS sys-
tem (Engine Management System)
automatically.
The vehicle will not
shut down if it is being driven and it
will require that it is stopped without
touching the throttle for 30 seconds
before doing so. If the buzzer acti-
vates shortly after driving again, check
the coolant level and fill it if necessary.
If the buzzer still activates after short-
ly please contact nearest authorized
LYNX dealer for further investigation.
Fan cooled models: Shut down the
engine.
Check for clogged air duct passages.
Remove any foreign materials.
Check for proper fan belt condition and
tension.
Liquid cooled models: Engine over-
heating pilot lamp will light up if engine
is too hot.
Reduce snowmobile speed and run
snowmobile in loose snow or stop en-
gine immediately.
Check for adequate coolant level. See
an authorized Lynx dealer.
Low Battery (only 4-tec models):
When overheating pilot lamp light up
does the fan starts to rotate, this usu-
ally takes down the voltage level under
its working level from this point will
EMS (Engine Management System)
increase the idle speed to 1500 RPM.
This gives naturally more current to
the battery and starts to charge it up.
If the battery pilot lamp stops lighting
(on V-800 it flashes) this means that
the battery loading up. But still the
idle speed does not come down at
this time, the engine must be stopped
before it starts to operate in normal
idle speed which is for V-800, 1200
RPM.
Fuel flooded engine
Install new spark plugs and restart en-
gine.
Rear suspension slider
shoe sticking
Slider shoes are cooled and lubricat-
ed by snow. When riding at moder-
ate or high speed on a thin-snow-cov-
ered surface, slider shoes may stick
on metallic track guides.
Run snowmobile on a surface covered
by snow or drive snowmobile at very
low speed.
Have slider shoes inspected by an au-
thorized Lynx dealer.
NOTE: This situation comes up the
more high profile track is. Avoid driv-
ing on hard packed snow, ice surface
or other surface, that has not enough
snow to ensure the lubrication.
It is noticeable that tracks with 35 mm
or more high profile are not meant for
the trail ride (hard surface) but only
for the deep snow ride. If the vehi-
cle which is equipped with this kind of
track, is driven on hard packed snow,
slider shoes may stick on track metal-
lic parts or the track can get damaged.
