Before removing the spark plug, be sure
to clean the area around the spark plug. If
you do not, dirt could enter engine when
removing or installing the spark plug.
Adjust the gap to specified amount (see
specifications chart) for proper ignition.
Use a feeler gauge to check the gap.

When installing the spark plug, be sure to
tighten it securely. A new spark plug should
be tightened 1/2 turn once the washer con-
tacts the cylinder head. A used spark plug
should be tightened 1/8-1/4 turn once the
washer contacts the cylinder head.
Brake
Arctic Cat recommends that the complete
brake system be checked daily for wear or
damage and for smooth operation. Periodi-
cally, the brake band should be inspected
for cracks and to ensure the liner is intact
and not worn excessively. Replace the
brake band if cracked or worn excessively.

3. Check the brake lever travel distance
periodically while tightening the for-
ward jam nut. When the distance is
within the specified range of 6-13 mm
(1/4-1/2 in.), tighten the rearward jam
nut to secure the adjustment.
Drive Chain
The drive chain should be lubricated
every 10 operating hours with Arctic Cat
Synthetic Chain Lube (p/n 0436-903) or
with a suitable dry, graphite-based chain
lubricant. By using the recommended
chain lube or a dry, graphite-based chain
lubricant, dirt buildup on the drive chain
will be minimized. Before each lubrica-
tion, inspect the drive chain for dirt accu-
mulation.
! WARNING
DO NOT operate the snowmobile
when any component in the brake
system is damaged, worn, or adjusted
improperly.
