OPERATION
Engine Break-In
Oil Injection System
Always check and fill the oil tank when refueling. See page 77.
NOTICE:
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 118 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
NOTICE:
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.
