Snowmobile Arctic Cat (2006 year). Instruction - part 7

GENERAL INFORMATION



NOTE: The measurements must

be equal and within the specifica-
tions from the chart. If the mea-
s u r e m e n t s a r e w i t h i n s p e c i -
fications, no adjustment is neces-
sary. If they are not within specifi-
cations, proceed to step 5.

5. Loosen the jam nut on the cable

housing to be adjusted; then

u s i n g t h e a d j u s t i n g n u t s ,

lengthen or shorten the housing

as needed.

6. While holding the adjusting nut

in place, tighten the jam nut

securely.

7. Install the actuating cables to

the servo; then install the servo

cover.

EXHAUST CONTROLLED
TIMING (ECT) SYSTEM (Firecat
500)

This system automatically adjusts

the ignition timing to provide maxi-

mum performance through a variety

of operating conditions. The CDI

unit receives input on engine RPM

(demand) and exhaust pipe tempera-

ture (engine condition) and adjusts

the ignition timing accordingly. This

system is not adjustable and is main-

tenance free.

Crossfire/M-Series

! CAUTION

The correct engine oil to use is
Arctic Cat Synthetic APV 2-
Cycle Oil (p/n 2639-512). Any
substitute may cause an APV
malfunction.

GENERAL INFORMATION

If a system fault is suspected, use an

ohmmeter to check continuity of the

exhaust pipe temperature sensor

located in the expansion chamber. A

reading of either 0 ohm or infinity

indicates a failed sensor.



NOTE: A disabled ECT system

WILL NOT cause engine damage;
however, a failed ECT system will
have slower throttle response and
may produce slightly less top-end
performance.

OPERATING INSTRUCTIONS

STARTING AND STOPPING
ENGINE

It is imperative that the brake system

be checked for wear and proper

operation and that all safety checks

found in the accompanying Snow-

mobile Safety Handbook be per-

formed before attempting to start the

engine. Also, on carbureted mod-

els, be sure the correct carburetor

main jet(s) for the operating tem-

perature, altitude, and gasoline

are being used, and on 2-stroke

EFI models, be sure the correct

fuel designation connection/ dis-

connection (for the type of gaso-

line being used) has been selected.

After the engine has been started,

check the headlights (high and low

beam), taillight, and brakelight to be

sure they are working properly and

adjusted correctly. Make sure all

lights are clean to provide maximum

illumination. The headlight and tail-

light must be clean and must be illu-

minated whenever the engine is

running.



NOTE: If equipped with reverse,

make sure the reverse shift lever
is in the forward position before
starting the engine.

1. Test the operation of the brake

system by compressing the

brake lever. The brake lever

must feel firm when com-

pressed; then while holding the

brake lever in the compressed

position, measure the distance

between the brake lever and the

handlebar (on hydraulic brake

models) or between the brake

l e v e r a n d l e v e r s t o p ( o n

mechanical brake models). The

distance must be greater than

2.54 cm (1 in.) on hydraulic

brake models or within a range

of 6-13 mm (1/4-1/2 in.) on

mechanical brake models.

734-505A

727-451A

! CAUTION

On 2-stroke EFI models, be sure
an adequate amount of gasoline
is in the gas tank. If you run out
of gasoline, engine damage may
occur.

OPERATING INSTRUCTIONS

2. On hydraulic brake models,

check the fluid level in the res-

ervoir. The brake fluid level

must be just below the high

mark in the brake fluid reser-

voir or visible in the sight glass.

Add Arctic Cat approved brake

fluid as necessary.

740-159A

0740-588

3. Test the throttle control lever by

completely compressing and

releasing it several times. The

lever MUST return to the idle

position quickly and com-

pletely.

4. Move the emergency stop

switch to the UP or RUN posi-

tion.

5. Insert key into ignition switch;

then rotate key to the RUN

position.

6. On carbureted models for a cold

engine, move the choke lever to

the full-choke position. If the

engine is warm, choking is nor-

mally not necessary.

0725-001



NOTE: On carbureted models

when the engine is being started
with aid of the choke, DO NOT
C O M P R E S S T H E T H R OT T L E
CONTROL LEVER. If the throttle
control lever is compressed, the
engine will not start because the
gas/air mixture will be too lean.
To start a warm engine, however,
the throttle control lever may
have to be compressed slightly.

! WARNING

Do not start the engine if the
brake system is not functioning
properly. Service the brake sys-
tem or have it properly repaired
prior to operating the snowmo-
bile. Serious personal injury or
even death may occur if the
brake system is not operating
properly.

! CAUTION

On liquid cooled models, always
check the coolant level before
starting the engine.
