Snowmobile Arctic Cat (2006 year). Manual - part 4

GENERAL INFORMATION

Low Oil Warning Light

The Low Oil Warning Light is

designed to alert the snowmobile

operator when the oil in the oil-

injection reservoir gets below a pre-

scribed level; however, it is highly

recommended that a visual verifica-

tion of the oil level in the reservoir

be done prior to operating the snow-

mobile.
Once the Low Oil Warning Light

illuminates during operation of the

snowmobile, the operator must peri-

odically monitor the level of oil in

the reservoir and must fill the reser-

voir the next time gasoline is added

to the gas tank. The “alert level” of

the Low Oil Warning Light is

approximately equal to 1 tankful of

gasoline under normal operating

conditions.

High Beam

On the Firecat/Sabercat/ ZR 900

models, the headlight HIGH/LOW

beam switch is incorporated into the

brake lever. Pushing the lever for-

ward will activate the switch. When

on HIGH beam, the high beam indi-

cator light will be illuminated.

Diagnostic Codes/Check
Engine/High Temperature
Warning Light (Carbureted
Models)

On the Firecat 500 if exhaust pipe

temperature is excessively high, the

check engine light will flash a warn-

ing (alert). Immediately shut off the

engine and determine the nature of

the problem (see Exhaust Controlled

Timing (ECT) System in this man-

ual).
The High Temperature Warning

Light is designed to alert the snow-

mobile operator when the tempera-

ture of the engine coolant exceeds a

safe operating temperature.

If the coolant temperature is at or

above 80° C (176° F), the high tem-

perature warning light will flash a

warning (alert). If the coolant tem-

perature is at or above 93° C (200°

F), the high temperature warning

light will cease flashing and will

remain constantly illuminated.



NOTE: At this point, the opera-

tor should take precautionary
measures such as changing to
loose snow terrain and/or check-
ing coolant level.

Additional codes are flashed by the

check engine light and high temper-

ature warning light. Refer to the fol-

lowing chart for diagnostic code

sequences.

! CAUTION

If unable to either determine or
remedy the problem, take the
snowmobile to an authorized
Arctic Cat Snowmobile dealer
for service.

GENERAL INFORMATION

Diagnostic Codes/Check Engine
(EFI Models)

If the coolant temperature is at or

above 80° C (176° F), the check

engine light will flash a warning

(alert). If the coolant temperature is

at or above 93° C (200° F), the

check engine light will cease flash-

ing and will remain constantly illu-

minated.

 NOTE: At this point, the operator
should take precautionary mea-
sures such as changing to loose
snow terrain and/or checking cool-
ant level.

Additional codes are flashed by the

check engine light. Refer to the fol-

lowing chart for diagnostic code

sequences.

HANDLEBAR TILT

The handlebar can be adjusted to the

position providing the operator with

the most comfort. To adjust the han-

dlebar, use the following procedure:



NOTE: It may be necessary to

remove the handlebar cover for
this procedure.

1. Loosen the four lock nuts secur-

ing the handlebar caps and

block to the steering post.

0734-406

2. Adjust the handlebar up or

down to operator’s desired tilt;

then tighten the lock nuts

evenly and securely. Check

steering for maximum right/left

turning capabilities.

3. Recheck lock nuts; tighten

securely.

! CAUTION

If unable to either determine or
remedy the problem, take the
snowmobile to an authorized Arc-
tic Cat Snowmobile dealer for ser-
vice.

GENERAL INFORMATION



NOTE: Recommended torque

value of lock nuts is 2.5 kg-m (18
ft-lb).



NOTE: Do not adjust the handle-

bar to a position that allows the
brake fluid to be below the low
mark on either side of the master
cylinder.

HANDLEBAR TILT
(Firecat/ZR 900/Turbo ST)

The handlebar can be adjusted to the

operator’s preference. To adjust the

handlebar, use the following proce-

dure:

1. Loosen the eight cap screws

securing the handlebar caps to

the riser and the riser to the

steering post.

735-501B

2. Adjust the handlebar up or

down to operator’s desired tilt,

tighten the cap screws evenly to

3.5 kg-m (25 ft-lb), and check

steering for maximum right/left

turning capabilities.



NOTE: Do not adjust the han-

dlebar to a position that allows
the brake fluid to be below the
low mark on either side of the
master cylinder.

EXHAUST SYSTEM

The exhaust system is designed to

reduce noise and to improve the total

performance of the engine. If any

e x h a u s t s y s t e m c o m p o n e n t i s

removed from the engine and the

engine is run, severe engine damage

will result.

AIR-INTAKE SILENCER

Used in conjunction with the fuel

intake system is a specially designed

air-intake silencer. The purpose of

the silencer is to quiet the intake of

fresh air. Since the fuel intake sys-

tem is calibrated with the air-intake

silencer in place, the engine must

never be run with the silencer

removed. Performance will not be

improved if the air-intake silencer is

removed. In contrast, severe engine

damage will occur.

! WARNING

Tighten lock nuts according to
specifications to prevent unex-
pected “movement” of the han-
dlebar during operation over
rough terrain and DO NOT posi-
tion handlebar so steering (max-
i m u m r i g h t / l e f t t u r n i n g
capabilities) or throttle and
brake controls are affected.

! WARNING

Tighten cap screws according
to specifications to prevent
unexpected “movement” of the
handlebar during operation over
rough terrain. DO NOT offset the
handlebar so steering (maxi-
mum right/left turning capabili-
ties) are altered or throttle and
brake controls will be affected.

! CAUTION

These snow mobiles are not
d e s i g n e d t o b e o p e r a t e d i n
dusty conditions. Operating the
snowmobile in dusty condi-
tions will result in severe engine
damage.

GENERAL INFORMATION

BATTERY

(Electric

Start Models)

It is extremely important that the

battery be maintained at full charge

at all times and that the battery con-

nections be clean and tight. If charg-

ing the battery becomes necessary,

refer to Charging Battery section of

this manual.

COOLING SYSTEM (Liquid)

Some snowmobiles are equipped

with a closed liquid cooling system

for engine cooling. The cooling sys-

tem should be inspected daily for

leakage and damage. Also, the cool-

ant level should be checked daily. If

leakage or damage is detected, take

the snowmobile to an authorized

Arctic Cat Snowmobile dealer for

service. If not under warranty, this

service is at the discretion and

expense of the snowmobile owner.
When filling the cooling system, use

a coolant/water mixture which will

satisfy the coldest anticipated

weather conditions of your area in

accordance with the coolant manu-

facturer’s recommendations. While

the cooling system is being filled, air

pockets may develop; therefore, run

the engine for five to ten minutes

after the initial fill, shut the engine

off, and then fill the cooling system

to approximately 51 mm (2 in.)

below the filler neck on 2-stroke

models or to just below the FULL

mark on 660 cc models.



NOTE: The 660 cc models are

equipped with a coolant “bleed
screw” on the purge tank (located
on the front-top of the engine).
After starting the engine (and
with the tank cap on and tight),
open the bleed screw slightly to
a l l ow t r a p p e d a i r t o e s c a p e .
Continue until no air is apparent;
then tighten the screw.

AO353A



NOTE: Use a good quality, gly-

col-based, automotive-type anti-
freeze.

DRIVE CLUTCH AND DRIVEN
PULLEY

The drive clutch and driven pulley

do not require lubrication; there-

fore, no special maintenance is

required by the snowmobile owner.

However, the drive clutch and

driven pulley should be disassem-

bled, cleaned, and inspected by an

authorized Arctic Cat Snowmobile

dealer after every 800 miles of oper-

ation or at the end of the snowmobil-

ing season whichever occurs first.

This service is at the discretion and

expense of the snowmobile owner.
When operating the snowmobile at

high altitudes, it may be necessary to

change certain component parts of

the drive clutch. See an authorized

Arctic Cat Snowmobile dealer for

further information.

! CAUTION

After operating the snowmobile
for the initial 5-10 minutes, stop
the engine, allow the engine to
cool down, and check the cool-
ant level. Add coolant as neces-
sary.
