Recommended Gasoline
The recommended gasoline to use in this snowmobile
is minimum 91 octane gasoline with a maximum 10%
ethanol content.

NOTE: For optimum performance, use only 91
octane (minimum) gasoline.
Gasolines containing more than 10% ethanol are not
acceptable gasoline for use in this snowmobile. Do not
use gasolines containing methanol.
Recommended Injection Oil
The recommended oil to use in the oil-injection system
is Arctic Cat C-TEC2 Synthetic 2-Cycle Oil (p/n
6639-520 - 48 oz) This oil is specially formulated to be
used and meets all of the lubrication requirements of
the Arctic Cat C-TEC2 snowmobile engine.
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 partic-
ularly if the tank is filled with cold gasoline 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 main-
tained 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.
During the break-in period (one tank of fuel), a maxi-
mum of 1/2 throttle (with varying throttle positions) is
recommended; however, brief full-throttle accelera-
tions and variations in driving speeds contribute to
good engine break-in.
Premixing fuel and oil during the break in period is not
required. With the oil delivery control strategy of the
electronic oil pump, the pump will automatically com-
pensate and deliver a richer fuel-to-oil ratio during the
engine break-in period.
Some may choose to pre-mix the first tank and if this
is the case, a pre-mix ratio of 100:1 is acceptable. A
pre-mix ratio of 100:1 combined with the richer fuel/
oil delivered from the electronic oil pump during
break-in may cause additional smoke at start up and
idle.
Preoperation Checks
1. Visually check all fluid levels. Add fluids as nec-
essary.
2. Visually check the entire snowmobile for any
loose fasteners. Tighten as required.
3. Start and run the engine to operating temperature.
4. Check all switches (tether, dimmer, brakelight,
emergency stop) to make sure all function prop-
erly; then visually check the headlight, taillight,
and brake light for proper illumination.
5. Test the operation of the brakes. The brake lever
must feel firm when the lever is compressed.
Inspect the brake fluid level. The brake fluid level
must be just below the high mark on the brake
fluid reservoir. Add Arctic Cat approved brake
fluid as necessary.
Checking Headlight Aim
1. Position the snowmobile on a level floor so the
headlight is approximately 8 m (25 ft) from an
aiming surface (wall or similar surface).

NOTE: There should be an “average” operating
load on the snowmobile when adjusting headlight
aim.
CAUTION
Do not use white gas or gasolines containing metha-
nol. Only Arctic Cat approved gasoline additives
should be used.
CAUTION
If a situation arises wherein 91 octane non ethanol or
91 octane with maximum 10% ethanol gasoline is not
available, 87 octane gasoline can be substituted in an
emergency; however, the prolonged usage of 87
octane gasoline can cause severe engine damage.
CAUTION
Any oil used in place of the recommended oil could
cause serious engine damage.
! 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 filling the gas tank. Do not sit on the
snowmobile without first installing the gas tank cap.
