DRIVE CHAIN

The drive chain should be lubricated
every 10 operating hours with Arctic
Cat Spray Lubricant (p/n 0436-903) or
with a dry, graphite-based chain lubri-
cant. By using the spray lubricant or a
dry, graphite-based chain lubricant, dirt
buildup on the drive chain will be min-
imized. Before
inspect the drive chain for dirt accumu-
lation.
To lubricate the drive chain, shut the
engine off and wait for all moving parts
0725-565
to stop, remove the drive chain shield,
and lubricate the drive chain. After
lubricating the drive chain, install the
drive chain shield.
 NOTE: If the spray lubricant or a
dry, graphite-based chain lubricant
is not available, lubricate the drive
chain with several drops of petro-
leum-based oil. If the snowmobile
is operated in the summer with the
optional wheel kit, the drive chain
should be lubricated more fre-
quently.
DRIVE CHAIN
TENSIONER
The drive chain tensioner is automatic;
therefore, no adjustment is required by
the snowmobile owner. The tensioner
and chain should be checked annually
for proper operation and excessive
wear and replaced when necessary.
Check the tensioner by pushing down
0735-457
on it and releasing it. It should immedi-
ately spring back and put tension on the
drive chain.
