ENGINE BREAK-IN
(2-Stroke Models)
The Arctic Cat 2-stroke 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 premixed
at a 100:1 ratio in all oil-injection
models.
During the break-in period, a maxi-
mum of 1/2 throttle is recom-
mended; however, brief full-throttle
accelerations and variations in driv-
ing speeds contribute to good engine
break-in. After one (1) tankful
break-in period, the snowmobile
may be taken to an authorized Arctic
C a t S n o w m o b i l e d e a l e r f o r a
checkup. This checkup is at the dis-
cretion and the expense of the snow-
mobile owner.
ENGINE BREAK-IN
(660 cc Models)
The Arctic Cat 660 cc engine (when
new or rebuilt) requires a short
break-in period before the engine is
subjected to heavy load conditions.
This engine does not require any
pre-mixed fuel during the break-in
period.
To ensure trouble-free operation,
careful adherence to the following
break-in guidelines will be benefi-
cial.
* With occasional full-throttle operation.
To ensure proper engine break-in on
standard models, Arctic Cat recom-
mends that the engine oil and filter
be changed after 600 miles or after
one month, whichever comes first.
This service is at the discretion and
expense of the snowmobile owner.
To ensure proper engine break-in on
Turbo models, Arctic Cat recom-
mends that the engine oil and filter
be changed after 200-500 miles.
This service is at the expense of the
snowmobile owner.
! CAUTION
DO NOT exceed the one (1) tank-
ful limitation of a 100:1 gas/oil
break-in mixture. Continuous
use of a gas/oil mixture, unless
c o n s i s t e n t l y o p e r a t i n g i n
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 ade-
q u a t e e n g i n e l u b r i c a t i o n i n
extremely cold conditions.
! CAUTION
DO NOT use premixed fuel in
t h e s n o w m o b i l e g a s t a n k .
Engine damage will occur.
