NOTE: Have the battery and elec-

ating the vehicle again.

Spark Plug(s)

This vehicle comes equipped with a speci-
fied spark plug. See the specifications
chart for the correct spark plug. A light
brown insulator indicates that the plug is
correct. A white or dark insulator indicates
that the engine may need to be serviced.
Consult an authorized Arctic Cat dealer if
the plug insulator is not a light brown
color. To help prevent cold weather foul-
ing, make sure to thoroughly warm up the
engine before operating.
To maintain a hot, strong spark, keep the
plug free of carbon.
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 (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.

Air Filter/Housing Drain

The air filter inside the air filter housing
must be kept clean to provide good
engine power and gas mileage. If the
vehicle is used under normal conditions,
service the filter at the intervals speci-
fied. If operated in dusty, wet, or muddy
conditions, inspect and service the filter
more frequently. Use the following pro-
cedure to remove the filter and inspect
and/or clean it.
Failure to inspect the air filter fre-
quently if the vehicle is used in dusty,
wet, or muddy conditions can dam-
age the engine.

NOTE: To access the air filter, the
seats and the center console must
be removed.
1. Remove dirt and debris from around
the filter housing.
2. Unsnap the four spring-clip fasteners
and remove the air filter cover.
3. Fill a wash pan larger than the ele-
ment with a non-flammable cleaning
solvent; then dip the element in the
ATV-0051
solvent and wash it.

NOTE: Foam Air Filter Cleaner
and Foam Air Filter Oil are available
from Arctic Cat.
4. Squeeze the element by pressing it
between the palms of both hands to
remove excess solvent. Do no twist or
ring the element or it will develop
cracks.
5. Dry the element.
6. Put the element in a plastic bag; then
pour in air filter oil and work the oil
into the element.
7. Squeeze the element to remove
excess oil.
ATV-0052
A torn air filter can cause damage to
the engine. Dirt and dust may get
inside the engine if the element is torn.
Carefully examine the element for tears
before and after cleaning it. Replace
the element with a new one if it is torn.
