Pre-operation checks
29
ESU11070
The condition of a snowmobile is the owner’s responsibility. Vital components can start to de-
teriorate quickly and unexpectedly, even if the snowmobile remains unused (for example, as a
result of exposure to the elements). Any damage or fluid leakage could have serious conse-
quences. Therefore, it is very important, in addition to a thorough visual inspection, to check
the following points before each ride.
NOTE:
Pre-operation checks should be made each time the snowmobile is used. Such an inspection
can be accomplished in a very short time; and the added safety it assures is more than worth
the time involved.
WARNING
EWS00190
If any item in the pre-operation check list is not working properly, have it inspected and
repaired before operating the snowmobile.
