Routine maintenance is necessary for all
mechanized products, and the snow-
mobile is no exception. Aweekly vehicle
inspection contributes to the life span
of
the snowmobile as well as retain safe and
trouble-free operation.
It is recommeded
that the steering system
and suspension, be lubricated
monthly or
every 40 hours of operation.
if the vehicle
is operated in wet snow or in
severe
conditions these items should be Iubri-
cated more frequently.
It is during summer, or when a vehicle is
not in use for any length of time that
proper storage isa necessity.
Storage of the snowmobile during long
periods of inactivity consists of checking
and replacing missing or worn parts:
Proper lubrication and treatments to
insure
that parts do not become rusted;
Cleaning items such as carburetor of oil
mixtures, to prevent gum varnish forma-
tion within the carburetor; and in general,
preparing the vehicle so
that when the
time comes to use the snowmobile again
it will start and be in
top condition.
Important: The necessity of proper
storage cannot be overstressed. If you
lack the ti me or proper tools,
see your
authorized dealer.
