6 GENERAL INFORMATION
Break-In Gas/Oil
Mixing Instructions
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 mix-
ing the gasoline and oil. To properly
mix the fuel at a 100:1 ratio, use the
following procedure:
1. Pour gasoline into the gasoline
container until approximately half
full.
2. Pour 236 ml (8 fl oz) of the recom-
mended 2-cycle oil into the gaso-
line container.
3. Install cap on gasoline container
and shake the mixture vigorously.
4. Fill the gasoline container with
gasoline; then cap the gasoline
container and shake the mixture
vigorously.
5. Using a fine-mesh screened fun-
nel, pour the fuel mixture from the
gasoline container into the snow-
mobile 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. Arctic Cat requires
that the first tankful of fuel be pre-
mixed at a 100:1 ratio in all oil-injec-
tion models.
During the break-in period, a maxi-
mum of 1/2 throttle is recommended;
however, brief full-throttle accelera-
tions and variations 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 Snowmobile
dealer for a checkup. This checkup is at
the discretion and the expense of the
snowmobile owner.
DRIVE BELT BREAK-IN
Drive belts require a break-in period of
approximately 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 flexibil-
ity and will extend drive belt life.

NOTE: Before starting the snow-
mobile in extremely cold tempera-
tures, 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-sec-
tion in the Maintenance section of
this manual).
CAUTION
Never mix oil and gasoline in the
snowmobile gas tank.
! WARNING
Always fill the gas tank in a well-
ventilated 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 filling the gas tank.
CAUTION
DO NOT exceed the one (1) tankful
limitation of a 100:1 gas/oil break-
in mixture. Continuous use of a
gas/oil
mixture, unless consis-
tently 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
system to ensure adequate engine
lubrication in extremely cold con-
ditions.
