Engine Break-In (Bearcat 570/T570 Models) - Arctic Cat Bearcat 570 Operator's Manual

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-
ventilated area. Never add gasoline
to the snowmobile gas tank near
any open flames or with the engine
running. DO NOT SMOKE while fill-
ing the gas tank. Do not sit on the
snowmobile without first installing
the gas tank cap.
Break-In Gas/Oil
Mixing Instructions
(Bearcat 570/T570
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 mix-
ing 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 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.

! 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.
ENGINE BREAK-IN
(Bearcat 570/T570
Models)
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.
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.
