3. Install the in-line fuel filter in the
fuel hose so the arrow on the filter
points toward the fuel pump.
Make sure the fuel hoses fit
tightly on the filter. If a fuel hose
does not fit tightly, cut 6 mm (1/4
in.) from the end of the fuel hose;
then install on the filter.
4. If applicable, turn the gas tank
shut-off valve to the OPEN posi-
tion.
Gasoline Additives
Fuel de-icer can be used for all mod-
els. Also, periodic use of an injector
cleaner for EFI models is recom-
mended especially in the last tank of
gasoline before storage. Arctic Cat
Fuel Stabilizer (p/n 0638-165) should
also be added to the last tank of gaso-
line before storage.
Fuel Pickup Valves
All 2-Stroke EFI models are equipped
with fuel pickup valves in the gas
tank. If ever there is a restricted fuel
flow and a pickup valve is suspected,
take the snowmobile to an authorized
Arctic Cat Snowmobile dealer for this
service. If not under warranty, this ser-
vice is at the discretion and expense of
the snowmobile owner.

OIL LEVEL
(660 cc Models)
NOTE: The snowmobile must
be on a level surface for this
procedure.
1. Open the hood and pull up on the
oil level stick until the top mark
on the stick is even with the top of
the oil level stick tube. Wait 30
seconds before proceeding.
NOTE: Failure to perform step
1 as stated will result in an inac-
curate reading.
2. After 30 seconds, remove the oil
level stick and wipe it with a
clean cloth. Insert the oil level
stick fully into the engine and
remove. Read the oil level shown
on the oil level stick. The oil level
must be between the two marks
on the bottom end of the stick.

3. If the oil level is at or below the
bottom mark on the oil level stick,
add recommended oil until the oil
level is slightly below the top
mark on the bottom end of the
stick.
! WARNING
The fuel hoses must fit tightly on
the fuel filter. If the fuel hose
length doesn’t permit this proce-
dure, replace the fuel hose. Also,
after installing the fuel hoses on
the filter, check to be sure that
the fuel hoses do not contact any
hot or rotating components.
