Snowmobile Arctic Cat (2006 year). Manual - part 3

GENERAL INFORMATION

Recommended Engine Oil
(660 cc Turbo)

The recommended oil to use is Syn-

thetic Turbo 0W-40 Oil (p/n 3639-

510).
After the engine break-in period, the

engine oil should be changed every

2500-3000 miles on standard 660 cc

models and every 2000 miles on

660 cc Turbo models and before

prolonged storage.

Filling Gas Tank

Since gasoline expands as its tem-

perature increases, the gas tank must

be filled to its rated capacity only.

Expansion room must be maintained

in the tank particularly if the tank is

filled with cold gasoline and then

moved to a warm area. Also, if the

snowmobile is to remain on a trailer

after filling the gas tank, the bed of

the trailer must be maintained level

to prevent gasoline from draining

out through the gas tank vent hose.

Break-In Gas/Oil Mixing
Instructions (2-Stroke Models)

Before mixing gasoline and oil,

make sure the oil is at room temper-

ature (20° C/68° F). Use a U.L.

approved 22.7 l (6 U.S. gal.) gaso-

line container for mixing the gaso-

line and oil. To properly mix the fuel

at a 100:1 ratio, use the following

procedure:

1. Pour gasoline into the gasoline

container until approximately

half full.

2. Pour 236 ml (8 fl oz) of the rec-

ommended 2-cycle oil into the

gasoline container.

3. Install cap on gasoline con-

tainer and shake the mixture

vigorously.

4. Fill the gasoline container with

gasoline; then cap the gasoline

container and shake the mixture

vigorously.

5. Using a fine-mesh screened

funnel, pour the fuel mixture

from the gasoline container into

the snowmobile gas tank.

! WARNING

Always fill the gas tank in a well-
ventilated area. Never add gaso-
line to the snowmobile gas tank
near any open flames or with
the engine running. DO NOT
SMOKE while filling the gas
tank. Do not sit on the snowmo-
bile without first installing the
gas tank cap.

! CAUTION

Never mix oil and gasoline in
the snowmobile gas tank.

! WARNING

Always fill the gas tank in a well-
ventilated area. Never add gaso-
line to the snowmobile gas tank
near any open flames or with
the engine running. DO NOT
SMOKE while mixing fuel or fill-
ing the gas tank.

GENERAL INFORMATION

ENGINE BREAK-IN
(2-Stroke Models)

The Arctic Cat 2-stroke engine

(when new or rebuilt) requires a

short break-in period before the

engine is subjected to heavy load

conditions. Arctic Cat requires that

the first tankful of fuel be premixed

at a 100:1 ratio in all oil-injection

models.
During the break-in period, a maxi-

mum of 1/2 throttle is recom-

mended; however, brief full-throttle

accelerations and variations in driv-

ing speeds contribute to good engine

break-in. After one (1) tankful

break-in period, the snowmobile

may be taken to an authorized Arctic

C a t S n o w m o b i l e d e a l e r f o r a

checkup. This checkup is at the dis-

cretion and the expense of the snow-

mobile owner.

ENGINE BREAK-IN
(660 cc Models)

The Arctic Cat 660 cc engine (when

new or rebuilt) requires a short

break-in period before the engine is

subjected to heavy load conditions.
This engine does not require any

pre-mixed fuel during the break-in

period.

To ensure trouble-free operation,

careful adherence to the following

break-in guidelines will be benefi-

cial.

* With occasional full-throttle operation.

To ensure proper engine break-in on

standard models, Arctic Cat recom-

mends that the engine oil and filter

be changed after 600 miles or after

one month, whichever comes first.

This service is at the discretion and

expense of the snowmobile owner.
To ensure proper engine break-in on

Turbo models, Arctic Cat recom-

mends that the engine oil and filter

be changed after 200-500 miles.

This service is at the expense of the

snowmobile owner.

! CAUTION

DO NOT exceed the one (1) tank-
ful limitation of a 100:1 gas/oil
break-in mixture. Continuous
use of a gas/oil mixture, unless
c o n s i s t e n t l y o p e r a t i n g i n
extremely cold conditions (-
26°C/-15°F or colder), could
cause spark plug fouling and
excessive carbon buildup. A
100:1 gas/oil mixture must be
used in conjunction with the oil-
injection system to ensure ade-
q u a t e e n g i n e l u b r i c a t i o n i n
extremely cold conditions.

! CAUTION

DO NOT use premixed fuel in
t h e s n o w m o b i l e g a s t a n k .
Engine damage will occur.

GENERAL INFORMATION

INDICATOR LIGHTS (Standard
Models)

Indicator lights are incorporated

within the speedometer.

LOW OIL WARNING LIGHT
(Standard 2-Stroke Models)

The Low Oil Warning Light is

designed to alert the snowmobile

operator when the oil in the oil injec-

tion 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 periodically monitor the level

of oil in the reservoir and must fill

the reservoir 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.

LOW OIL PRESSURE WARNING
LIGHT (660 cc Models)

The Low Oil Pressure Warning

Light indicates engine oil pressure,

not the oil level; however, if the oil

level is low, it may affect oil pres-

sure. The light should illuminate

each time the ignition switch is

turned to RUN or START, and it

should go out when the engine

starts. If the light illuminates while

the engine is running, oil pressure

has been lost and the engine will

automatically shut off.
If oil pressure is lost, use the follow-

ing procedure:

1. Check the oil level.



NOTE: To ensure an accurate

reading, the snowmobile should
be on level ground.

2. If the oil level is below the

lower mark on the oil level

stick, add only enough recom-

mended oil to raise the level

between the upper and lower

marks. DO NOT overfill the

crankcase with oil.

3. After adding oil if the engine

starts, oil pressure should be

normal.

If the engine does not start, take the

snowmobile to an authorized Arctic

Cat Snowmobile dealer.

HIGH TEMPERATURE
WARNING LIGHT
(Standard Liquid Cooled
Models)

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

High Temperature Warning Light

illuminates during operation of the

snowmobile, immediately shut off

the engine and determine the nature

of the problem (low coolant level,

etc.). If unable to either determine or

remedy the problem, take the snow-

mobile 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.



NOTE: Operating the snowmo-

bile at slow speed over minimal
snow or hard pack terrain may
c aus e exces sive engine heat
build-up. If the High Temperature
Warning Light illuminates under
these conditions, immediately
change to a loose snow terrain.

GENERAL INFORMATION

CHARGING SYSTEM WARNING
LIGHT (660 cc Models)

The Charging System Warning

Light is designed to warn the opera-

tor if the battery charging system is

not functioning. The light should

illuminate each time the key is

turned to RUN or START, and it

should go out when the engine

starts. If the light stays illuminated

or it illuminates while the engine is

running, the battery is not being

charged, and the snowmobile is run-

ning on battery reserve power only.
If the Charging System Warning

Light illuminates, you should, as

soon as possible, take the snowmo-

bile 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. The engine

WILL NOT RUN without battery

power.

CHECK ENGINE LIGHT
(660 cc Models)

The Check Engine Light is con-

trolled by the ECU and may illumi-

nate for a number of reasons. The

light should illuminate each time the

key is turned to RUN or START, and

it should go out when the engine

starts. If the light stays illuminated

or it illuminates while the engine is

running, the ECU is receiving input

that is outside of its established

parameters. If the Check Engine

Light illuminates, take the snowmo-

bile 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.

SPEEDOMETER/TACHOMETER

Some models are equipped with a

combination speedometer/tachome-

ter. Also incorporated into the

speedometer/tachometer are a digi-

tal readout screen and indicator

lights (battery, low oil, high beam,

check engine, and high tempera-

ture).



NOTE: The functions of the dig-

ital readout and indicator lights
will vary from model to model.

Top Button

By pushing the top button once

(lower right-hand side of the speed-

ometer/tachometer), the RPM and

MPH will be displayed (one on the

readout screen and one with the nee-

dle). By pushing the button once

again, the functions will be reversed.
By pushing the top button (with

speed being displayed) for more

than two seconds, the display will

show between standard mph or met-

ric kph. Release the button when

desired display appears.
By pushing and holding the top but-

ton, maximum RPM will be dis-

played on the readout screen. The

maximum RPM readout will reset

when the engine is shut off.

Bottom Button

By pushing the bottom button once,

the readout screen will display hour-

meter or trip-meter/odometer; by

pushing the button once again, the

two functions will be reversed. The

hour-meter readout will not reset.
