Break-In Gas/Oil Mixing
Instructions (2000)
Before mixing gasoline and oil, make sure
the oil is at room temperature (20° C/68°
F). Use a U.L. approved 22.7 l (6 U.S. gal.)
gasoline container for mixing the gasoline
and oil. To properly mix the fuel at a 100:1
ratio, use the following procedure:
1. Pour gasoline into the gasoline con-
tainer until approximately half full.
2. Pour 236 ml (8 fl oz) of the recom-
mended 2-cycle oil into the gasoline
container.
3. Install cap on gasoline container and
shake the mixture vigorously.
4. Fill the gasoline container with gaso-
line; then cap the gasoline container
and shake the mixture vigorously.
5. Using a fine-mesh screened funnel,
pour the fuel mixture from the gasoline
container into the snowmobile gas tank.
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.
2000
Arctic Cat requires that the first tankful
of fuel be premixed at a 100:1 ratio in all
oil-injection models.
During the break-in period, a maximum
of 1/2 throttle is recommended; however,
brief full-throttle accelerations and varia-
tions in driving speeds contribute to good
engine break-in. After one (1) tankful
break-in period, the snowmobile may be
taken to an authorized Arctic Cat Snow-
mobile dealer for a checkup. This
checkup is at the discretion and the
expense of the snowmobile owner.
5000
This engine does not require any pre-
mixed fuel during the break-in period.
To ensure trouble-free operation, careful
adherence to the following break-in
guidelines will be beneficial.
* With occasional full-throttle operation.
To ensure proper engine break-in, Arctic
Cat recommends that the engine oil and
filter be changed after 500 miles. This
service is at the discretion and expense of
the snowmobile owner.
Drive Belt Break-In
Drive belts require a break-in period of
approximately 25 miles. Drive the snow-
mobile 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 temperature,
install the drive belt (see Drive Belt sub-
section in the Maintenance section).
CAUTION
Never mix oil and gasoline in the
snowmobile gas tank.
! WARNING
Always fill the gas tank in a well-ven-
tilated area. Never add gasoline to the
snowmobile gas tank near any open
flames or with the engine running. DO
NOT SMOKE while mixing fuel or fill-
ing the gas tank.
CAUTION
DO NOT exceed the one (1) tankful limi-
tation of a 100:1 gas/oil break-in mix-
ture. Continuous use of a gas/oil
mixture, unless consistently operating
in extremely cold conditions (-26°C/-
15°F or colder), could cause spark plug
fouling and excessive carbon buildup. A
100:1 gas/oil mixture must be used in
conjunction with the oil-injection sys-
tem to ensure adequate engine lubrica-
tion in extremely cold conditions.
CAUTION
DO NOT use premixed fuel in the
snowmobile gas tank. Engine dam-
age will occur.
