„

NOTE: High engine RPM, low vehicle speed, or

heavy load can raise engine temperature. Decreas-
ing engine RPM, reducing load, and selecting an
appropriate transmission gear can lower the tem-
perature.

„

NOTE: Debris in front of the engine (or packed

between the cooling fins of the radiator on the 400/
500 or packed between the oil cooler cooling fins
on the 250/300/375) can reduce cooling capability.
Using a hose, pressure-wash the radiator (engine
and oil cooler on the 250/300/375) to remove any
debris preventing air flow to the radiator.

3.

Neutral Indicator

 — A green light will illuminate

when the transmission is in neutral and the ignition

switch is on. The light will go out when shifted

into any gear other than neutral.

 4.

Reverse Indicator

 — An orange light will illumi-

nate when the transmission is shifted into reverse

gear. The light will go off when shifted out of

reverse.

5.

Gear Position Indicator (Manual Transmis-

sion) 

— A yellow light will illuminate to indicate

which gear (1-5) the transmission is shifted into.

Frame/Welds/Racks

The frame, welds, and racks should be checked period-

ically for damage, bends, cracks, deterioration, broken

components, and missing components. If replacement

or repair constitutes removal, see Section 8.

Electrical Connections

The electrical connections should be checked periodi-

cally for proper function. In case of an electrical fail-

ure, check fuses, connections (for tightness, corrosion,

damage), and/or bulbs. If an electrical component

needs to be tested for proper function, see Section 5.

2. Compress the brake lever several times to check

for a firm lever. If the lever is not firm, the brake

system must be bled.

3. To bleed the brake system, use the following pro-

cedure.

A. Remove the cover and fill the master cylinder

with DOT 4 Hi-Temp Brake Fluid (p/n

1639-799).

B. Install and secure the cover; then slowly

compress the brake lever several times.

C. Remove the protective cap, install one end of a

clear hose onto one FRONT bleeder screw, and

direct the other end into a container; then while

holding slight pressure on the brake lever, open

the bleeder screw and watch for air bubbles.

Close the bleeder screw before releasing the

brake lever. Repeat this procedure until no air

bubbles are present.

AF637D

730-434B

„

NOTE: During the bleeding procedure, watch the

master cylinder reservoir very closely to make
sure there is always a sufficient amount of brake
fluid. If the fluid level gets below the bottom line on
the reservoir, refill the reservoir before the bleed-
ing procedure is continued.

D. Repeat step C until the brake lever is firm.

E. At this point, perform step B, C, and D on the

other FRONT bleeder screw; then move to the

REAR bleeder screw and follow the same

procedure.

4. Carefully check the entire hydraulic brake system

that all hose connections are tight, the bleed

screws are tight, the protective caps are installed,

and no leakage is present.

INSPECTING HOSES

Carefully inspect the hydraulic brake hoses for cracks

or other damage. If found, the brake hoses must be

replaced.

CHECKING/REPLACING PADS

The clearance between the brake pads and brake discs

is adjusted automatically as the brake pads wear. The

only maintenance that is required is replacement of the

brake pads when they show excessive wear. Check the

thickness of each of the brake pads as follows.

1. Remove a front wheel.

5. If the free-play gap is not within tolerance, read-

just the jam nuts of the adjuster arm in 1/4 turn

increments until the correct free-play gap is

attained.

„

NOTE: Apply the foot brake a number of times to

ensure the wheels lock and the brakelight illumi-
nates properly.

6. If the rear cable adjustment is inadequate to attain

the proper brake pedal arm free-play gap, make

adjustment at the front cable adjuster jam nuts.

MEASURING/REPLACING BRAKE PADS

Removing

1. Support the ATV on a suitable stand.

(40 ft-lb).

4. Adjust the brake (see Adjusting in this sub-sec-

tion).

5. Remove the ATV from the support stand.

„

NOTE: Whenever installing new pads, the new

pads must be burnished (see Burnishing Brake
Pads in this section).

Burnishing Brake Pads

Brake pads (both hydraulic and mechanical) must be

burnished to achieve full braking effectiveness. Brak-

ing distance will be extended until brake pads are

properly burnished. To properly burnish the brake

pads, use the following procedure.

1. Choose an area large enough to safely accelerate

the ATV to 30 mph and to brake to a stop.

2. Accelerate to 30 mph; then compress brake lever

or apply the mechanical foot brake to decelerate to

0-5 mph.

! CAUTION

If adjusting the rear cable at both ends does not
attain proper brake pedal arm free-play, the brake
pads must be replaced.

! WARNING

Failure to properly burnish the brake pads could
lead to premature brake pad wear or brake loss.
Brake loss can result in severe injury.

3. Repeat procedure on each brake system 5 times

until brake pads are burnished.

4. Adjust the mechanical brake (if necessary).

5. Verify that the brakelight illuminates when the

hand lever is compressed or the brake pedal is

depressed.

Coolant

(400/500)

The cooling system capacity is approximately 2.9 L (3

U.S. qt). The cooling system should be inspected daily

for leakage and damage. Also, the coolant level should

be checked periodically.

When filling the cooling system, use premixed Arctic

Cat Antifreeze (p/n 0638-395). While the cooling sys-

tem is being filled, air pockets may develop; therefore,

run the engine for five minutes after the initial fill, shut

the engine off, and then fill the cooling system to the

bottom of the stand pipe in the radiator neck.
