Filling Gas Tank
Since gasoline expands as its temperature
increases, the gas tank must be filled to
its rated capacity only. Expansion room
must be maintained in the tank particu-
larly if the tank is filled with cold gaso-
line and then moved to a warm area.
Also, if the snowmobile is to remain on a
trailer after filling the gas tank, the bed of
the trailer must be maintained level to
prevent gasoline from draining out
through the gas tank vent hose.
Engine Break-In
The Arctic Cat engine (when new or
rebuilt) requires a short break-in period
before the engine is subjected to heavy
load conditions.
Premixing fuel and oil during the break
in period is not required. There is never a
more important period in the life of the
engine than the first 300 miles.
Since the engine is brand new, do not put
an excessive load on it for the first 300
miles. 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 must be avoided.
0-160 km (0–100 miles): Avoid pro-
longed operation above 6000 RPM.
160-500 km (100–300 miles): Avoid pro-
longed operation above 8000 RPM.
500 km (300 miles) and beyond: The snow-
mobile can now be operated normally.
NOTE: After 500 miles of opera-
tion, the engine oil must be changed
and the oil filter replaced. If any
engine trouble should occur during
the engine break-in period, immedi-
ately have a Arctic Cat dealer check
the snowmobile.
Drive Belt Break-In
Drive belts require a break-in period of 25
miles. Drive the snowmobile for 25 miles
at 3/4 throttle or less. By revving the
engine up and down (but not exceeding 60
mph), the exposed cord on the side of a
new belt will be worn down. This will
allow the drive belt to gain its optimum
flexibility and will extend drive belt life.
NOTE: Before starting the snowmo-
bile in extremely cold temperatures,
the drive belt should be removed and
warmed up to room temperature.
Once the drive belt is at room tem-
perature, install the drive belt (see
Drive Belt sub-section in the Mainte-
nance section).
Cold Drive-Away
Function
On these models, there is a “cold drive-
away” function incorporated within the
ECM.
When cold-starting the engine, the cool-
ant temperature warning icon will illumi-
nate and the TEMP display on the
readout screen will begin to flash. With
the engine in this temperature range, the
RPM “limit” of the engine will be below
drive system engagement speed. As the
engine warms, the coolant temperature
warning icon will begin to flash, the
TEMP display will continue to flash, and
the RPM “limit” of the engine will
increase allowing the snowmobile to
move without full-throttle operation.
When the engine reaches proper operat-
ing temperature, the coolant temperature
warning icon and the TEMP display will
go out.
! WARNING
Always fill the gas tank in a well-venti-
lated area. Never add gasoline to the
snowmobile gas tank near any open
flames or with the engine running. DO
NOT SMOKE while filling the gas tank.
CAUTION
Never run the engine with the drive
belt removed. Excessive revving of
the engine could result in serious
engine damage and drive clutch fail-
ure.
