Periodic maintenance

ESU11450

Safety is an obligation of the owner. Periodic inspection, adjustment, and lubrication will keep
your snowmobile in the safest and most efficient condition possible. The most important points
of snowmobile inspection, adjustment, and lubrication are explained on the following pages.

Maintenance, replacement, or repair of the emission control devices and systems may
be performed by any repair establishment or individual that is certified (if applicable).

WARNING

EWS00340

If you are not familiar with maintenance work, have a Yamaha dealer do it for you.

PROPER PERIODIC MAINTENANCE OF YOUR SNOWMOBILE IS IMPORTANT IN ORDER
TO ENJOY LONG, PLEASURABLE SERVICE. ESPECIALLY IMPORTANT ARE THE MAIN-
TENANCE SERVICES RELATED TO EMISSION CONTROL. THESE CONTROLS NOT
ONLY FUNCTION TO ENSURE CLEANER AIR, BUT ARE ALSO VITAL TO PROPER EN-
GINE OPERATION AND MAXIMUM PERFORMANCE. IN THE FOLLOWING PERIODIC
MAINTENANCE CHARTS, THE SERVICES RELATED TO EMISSION CONTROL ARE
GROUPED SEPARATELY. THESE SERVICES REQUIRE SPECIALIZED DATA, KNOWL-
EDGE, AND EQUIPMENT. YAMAHA DEALERS ARE TRAINED AND EQUIPPED TO PER-
FORM THESE PARTICULAR SERVICES.
