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. During the
first three hours of operation, operate the snowmobile as outlined in the
Engine Break-In section.
Avo id Heat Build-Up
Excessive heat build-up during the first few hours of operation will
damage close-fitted engine parts. Do not operate at full throttle or high
speeds for extended periods during the first 100 miles (160 km)of use.
Vary the throttle openings and machine speeds t o reduce friction on all
close-fitting machined parts, allowing them to break in slowly without
damage.
Perform Fluid Checks
Perform regular checks on fluid levels, lines, and all other important
areas of the machine. P erform the first oil and filter change at 1000
miles (1600 km). See page 87.
CAUTION
Failure to follow the procedures outlined in the Engine Break-In
section of the owner’s manual could result in serious damage to
the snowmobile. Follow all procedures as outlined.
