OPERATION
Engine Break-In
Oil Injection System
Always fill the oil tank when refueling. See page 63.
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.
Oil Recommendations
This snowmobile is equipped with a variable exhaust system (VES).
Engine lubrication comes from oil added to the fuel and oil injection
systems. Polaris recommends the use of VES II 2 Cycle Oil for this
engine. See page 108 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
Inadequate cooling and lubrication will lead to overheating of the
slide rail and track, resulting in premature wear and failure.
Reduce speeds and frequently 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.
CAUTION
High speed use on hardpacked surfaces is not recommended for
models equipped with a deep lug track. Track lug damage may
occur. Keep high speed use to a minimum, including frequent
slow-speed intervals for track cooling.
