OPERATION
Engine Break-In
No single action on your part is as important to long, trouble-free
machine life as proper break-in of a new or rebuilt engine. Premix the
first 3.5 gallons (13.2 l) of gasoline with 16 oz. (473 ml) of the
recommended 2-cycle racing oil (28:1). Premix future gasoline at 32:1.
CAUTION
Excessive heat build-up during the first three hours of operation
will damage close-fitted engine parts. Do not operate at full
throttle or high speeds for extended periods during the first three
hours of use. Vary the throttle openings and machine speeds to
reduce friction on all close-fitting machined parts, allowing them
to break in slowly without damage.
Use of any lubricants other than those recommended by Polaris
may cause serious engine damage. We recommend the use of
Polaris lubricants for your vehicle.
Drive with extra caution during the break-in period. Perform
regular checks on fluid levels, lines, and all other important areas
of the machine.
Oil Recommendations
The only source of engine lubrication for your engine comes from
lubrication added to the fuel. We highly recommend the use of only
Polaris products. We’re continuously testing lubricants and provide the
highest performance products available for your snowmobile’s engine.
We recommend the use of Polaris 2-Cycle Racing Oil for your
snowmobile . See page 103 for the part numbers of Polaris products.
Never mix brands of oil. Serious chemical reactions can cause system
blockage, resulting in serious engine damage. They may also be
incompatible and the result could be sludge formation, filter blockage,
and reduced cold weather flow rates. All Polaris oils are compatible
with each other.
