Snowmobile Arctic Cat (2006 year). Instruction - part 15

MAINTENANCE

ENGINE HEATER
(660 cc Models)

The engine heater will help provide

easier starting in cold weather. Arc-

tic Cat recommends that the heater

be plugged in any time the tempera-

ture is expected to get below -15°F.

The heater cord is stored on the left

rear of the engine compartment just

above the air-intake vent.

MECHANICAL BRAKE SYSTEM

Arctic Cat recommends that the

brake system (brake lever, brake

lever travel, cable, caliper, spring,

and disc) be checked daily for wear

or damage, smooth operation, and

proper adjustment.

Checking Brake Lever Travel

1. Rotate the brake disc alternately

forward and backward while

slowly compressing the brake

lever.

2. At the point where the disc is

locked, check the distance

between the brake lever and the

lever stop. The distance must be

within a range of 6-13 mm (1/4-

1/2 in.).

727-451A

3. If distance is not within specifi-

cations, adjust the brake lever

travel.

Adjusting Brake Lever Travel

1. To decrease brake lever travel

(set up brakes), pull out on the

brake adjustment knob and

rotate the knob clockwise. As

you rotate the knob, periodi-

cally check the brake lever

travel distance until the correct

travel distance is attained. Once

the correct brake lever travel

has been obtained, release the

adjustment knob into a secured

position.



NOTE: If the brake adjustment

knob has reached its maximum
adjustment (cannot be rotated
any further clockwise), both brake
pads must be replaced.

! WARNING

DO NOT operate the snowmo-
bile when the parking brake is
engaged or when any compo-
nent in the brake system is dam-
a g e d , w o r n , o r a d j u s t e d
improperly. If the snowmobile is
operated and the brake system
is not functioning properly,
severe personal injury could
result.

! WARNING

Before making any adjustment,
make certain the brake adjust-
ment knob isn’t hot. If the snow-
mobile has just been used, you
must allow some time for the
brake adjustment knob to cool
or burns may occur.

MAINTENANCE

730-151A

2. To increase brake lever travel

(loosen the brake), pull out on

the brake adjustment knob and

rotate the knob counterclock-

wise while checking the brake

lever travel. Once the desired

brake lever travel is obtained,

release the adjustment knob

into a secured position.



N OT E : W h e n a d j u s t i n g t he

brake, do not accidentally close
the gas tank shut-off valve.



NOTE: When new brake pads

are installed, a “burnishing” pro-
cess is required. Drive the snow-
mobile slowly and compress the
brake lever several times until the
pads just start to warm up; then
allow them to cool down. This
p ro c edu r e s t a b i li z e s t h e p ad
material and extends the life of
the pads.

HYDRAULIC BRAKE SYSTEM

Arctic Cat recommends that the

brake system (brake lever, fluid res-

ervoir, hose, caliper, pads, and brake

disc) be checked daily for fluid leak-

age, wear, or damage and for proper

operation. Also, the brake fluid level

must be checked every time before

starting the engine. The brake fluid

must be maintained at a level just

below the high mark on the fluid res-

ervoir.

Checking/Adding Brake Fluid

1. With the fluid reservoir/sight

glass reservoir in a level posi-

tion, check the fluid level. The

brake fluid level must be just

below the high mark in the

brake fluid reservoir or visible

in the sight glass.



NOTE: If the sight glass appears

dark, there is a sufficient amount
of fluid in the reservoir.

! WARNING

DO NOT attempt to adjust the
brake with the flange nuts on
the brake cable bracket. Incor-
r e c t b r a k e a d j u s t m e n t m ay
occur causing possible brake
failure.

! WARNING

When the brak e a dj us tme nt
knob has reached its maximum
adjustment, both brake pads
MUST BE REPLACED. Take the
snowmobile to an authorized
Arctic Cat Snowmobile dealer
for this service. This service is
at the discretion and expense of
the snowmobile owner.

! WARNING

DO NOT operate the snowmo-
bile when the brake lever lock is
engaged or when any compo-
nent in the brake system is dam-
a g e d , w o r n , o r a d j u s t e d
improperly. If the snowmobile is
operated and the brake system
is not functioning properly,
severe personal injury could
result.

2. If the brake fluid level is below

the low mark or not visible in

the sight glass, remove the res-

ervoir cover and add Arctic Cat

approved brake fluid until the

fluid is at the recommended

level. Install and secure the res-

ervoir cover. Do not allow

moisture to contaminate the

brake system.

Changing Brake Fluid

The brake fluid must be changed on

a regular basis and whenever the

brake fluid has been overheated or

contaminated. The brake fluid

should be changed every 1000 miles

or at the end of the snowmobiling

season, whichever occurs first. Take

the snowmobile to an authorized

Arctic Cat Snowmobile dealer for

this service. This service is at the

discretion and expense of the snow-

mobile owner.

Checking Brake Lever Travel

Before each use, check the brake

lever travel using the following pro-

cedure:

1. Compress the brake lever fully.



NOTE: Do not pump the brake

lever as it will produce an inaccu-
rate reading.

2. Measure the distance between

the brake lever and the handle-

bar. The distance must be

greater than 2.54 cm (1 in.).

! CAUTION

Brake fluid is highly corrosive.
Do not spill brake fluid on any
surface of the snowmobile.

! WARNING

Do not overfill the brake fluid
reservoir. Overfilling the reser-
voir may cause the brake sys-
tem to hydraulically lock. Use
only Arctic Cat approved brake
fluid. Never substitute or mix
different types or grades of
b r a k e f l u i d . B r a k e l o s s c a n
result. Brake loss can result in
severe injury or even death.

MAINTENANCE

734-505A

3. If the resultant distance is less

than specified, take the snow-

mobile to an authorized Arctic

Cat Snowmobile dealer for ser-

vice. This service is at the dis-

cretion and expense of the

snowmobile owner.

Bleeding Brake System

If the brake lever feels spongy when

applied, the brake system may need

to be bled. To bleed the brake, use

the following procedure:



NOTE: The brake system may

be bled by the snowmobile owner
if qualified to do so. If the owner
does not feel qualified, take the
snowmobile to an authorized Arc-
tic Cat Snowmobile dealer for this
service. This service is at the dis-
cretion and expense of the snow-
mobile owner.

1. Remove the reservoir cover and

fill the reservoir to the high

mark with Arctic Cat approved

brake fluid.

2. Slide a piece of flexible tubing

over the ball of the bleeder

valve and direct the other end

into a container.

! WARNING

Do not operate the snowmobile
i f t h e c o m p r e s s e d d i s t a n ce
between the brake lever and the
handlebar is less than 2.54 cm
(1 in.). Brake loss may occur.
Brake loss can result in severe
personal injury.

! CAUTION

Brake fluid is highly corrosive.
Do not spill brake fluid on any
surface of the snowmobile.

! WARNING

Use only Arctic Cat approved
brake fluid. Any substitute may
result in a loss of brakes.
