Engine Break-In - Arctic Cat Bearcat 570 2012 Operator's Manual

Recommended Injection
Oil (F5 LXR/570 cc
Models)
The recommended oil to use in the oil-
injection system is Arctic Cat Formula 50
Injection Oil (p/n 5639-475 - qt) or (p/n
5639-476 - gal.). This oil is specially for-
mulated to be used either as an injection
oil or as a pre-mix oil (for break-in) and
meets all of the lubrication requirements
of the Arctic Cat snowmobile engine.
CAUTION
Any oil used in place of the recom-
mended oil could cause serious
engine damage.
Recommended Engine Oil
(1100 cc Models)
The recommended oil to use is Synthetic
0W-40 Oil (p/n 5639-172 - qt) or (p/n
5639-173 - gal.).
After the engine break-in period, the
engine oil should be changed every 2500-
3000 miles on the non-turbo models or
1500-2000 miles on the turbo model and
before prolonged storage.
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.
! 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 filling the gas
tank. Do not sit on the snowmobile
without first installing the gas tank
cap.

Break-In Gas/Oil Mixing
Instructions (F5 LXR/570
cc Models)
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:
CAUTION
Never mix oil and gasoline in the
snowmobile gas tank.
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 gaso-
line container into 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.

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.
F5 LXR/570 cc Models
Arctic Cat requires that the first tankful
of fuel be premixed at a 100:1 ratio in all
oil-injection models.
