OPERATION
Engine Break-In
Oil Injection System
Always check and fill the oil tank when refueling. See page 60.
Oil Recommendations
Engine lubrication comes from oil added to the fuel and oil injection
systems. On Polaris snowmobiles equipped with a variable exhaust sys-
tem (VES), Polaris highly recommends the use of only VES II 2 Cycle
Oil. See the table below for additional oil recommendations. See page
125 for the part numbers of Polaris products.
Never mix brands of oil. Serious chemical reactions can cause injection
system blockage, resulting in serious engine damage. Oils 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.
Slide Rail and Track Cooling
CAUTION
Serious engine damage can occur without the proper lubrication. Check the
oil tank level often during the first tank of fuel. If the oil level doesn't go down,
contact your dealer immediately.

CAUTION
Inadequate cooling and lubrication will lead to overheating of the slide rail
and track, resulting in premature wear and failure. Reduce speeds and fre-
quently drive into fresh snow to allow adequate cooling and polishing of the
slide rail and track surfaces. Avoid operating on ice, hard-packed surfaces or
roads.
