Snowmobile Arctic Cat (2006 year). Manual - part 6

GENERAL INFORMATION

REVERSE TRANSMISSION

The reverse transmission offers the

operator the convenience of being

able to back up the snowmobile

rather than having to turn the snow-

mobile around by hand. This fea-

ture, under most situations, should

not be used to free a stuck snowmo-

bile as it will tend to dig the skis

deeper into the snow. Before starting

the snowmobile, be sure the shift

lever is in the desired position for

either forward or reverse operation.

Always use minimal speed when

operating in reverse and come to a

complete stop before shifting from

either forward to reverse or reverse

to forward. Once you have shifted to

a new gear, apply slight throttle until

positive engagement of the shift has

been observed. To shift the reverse

transmission, use the following pro-

cedure:

1. Come to a complete stop.
2. Either push or pull the shift

lever to the desired position;

then apply slight throttle until

positive engagement of the shift

has been observed.

737-831A

No special maintenance is required

for the reverse transmission; how-

ever, if chattering is experienced

when the transmission is shifted into

reverse, the linkage may have to be

adjusted. Arctic Cat recommends

taking the snowmobile to an autho-

rized Arctic Cat Snowmobile dealer

for this service. If not under war-

ranty, this service is at the discretion

and expense of the snowmobile

owner.



NOTE: A warning buzzer will

sound when the transmission is
in the reverse position; however,
always check the position of the
shift lever before accelerating.

TOWING

If the snowmobile is to be towed by

another snowmobile, do not tow

using the loops in the skis. The tow

rope should be attached to the spin-

dles.

! WARNING

DO NOT stand behind the snow-
mobile or near the rotating track.
NEVER run the track at high speed
when the track is suspended.

! WARNING

Use caution and minimal speed
when operating the snowmo-
bile in reverse. Be sure the shift
lever is in the desired lever posi-
tion.

GENERAL INFORMATION

ADJUSTABLE BACKREST

The adjustable backrest is designed

for maximum comfort and safety.

When riding double, the backrest

must be adjusted to the most rear-

ward position. When riding single,

the backrest should be moved for-

ward to a position comfortable to the

operator. Be sure to maintain the

backrest pad in a vertical position in

all locations. Also, be sure to tighten

all retaining knobs securely after

adjusting the backrest.

backrest in the forward posi-

tion.

2. Pull back on the seat latch han-

dle located at the bottom rear of

lowing procedure:

1. Place the seat into position on

the tunnel making sure the two

pins on the front of the rear seat

are properly engaged with the

receiving tabs on the rear of the

front seat.

2. Pull back on the seat latch han-

dle; then with the seat latch

handle pulled back, push the

rear seat forward and down and

release the seat latch handle.

! WARNING

Moving the backrest forward
limits the seating capacity to
one person only.

! CAUTION

On models equipped with a seat
warmer, disconnect the warmer
wiring harness prior to fully
removing the seat.

ARCTIC POWER VALVE
(APV) SYSTEM

This RPM controlled servomotor

(servo) actuated system adjusts the

size of the exhaust ports to provide

peak performance throughout the

RPM range. The system consists of

an exhaust valve assembly mounted

to the exhaust side of each cylinder

and connected by adjustable cables

to an electronic servo mounted

beneath the hood.



NOTE: The mounting location of

the servo will vary from model to
model.

739-152E

0739-152

At low RPM, the exhaust valves are

held in the DOWN position by

return springs. This gives the engine

a “low port” exhaust design cali-

brated to provide maximum low

RPM power and improve fuel econ-

omy at trail speeds.

739-152C

! WARNING

Make sure the seat is securely
locked in place or pers onal
injury may result.

GENERAL INFORMATION

739-152A

At high RPM, the exhaust valves are

raised. This creates a “high port”

exhaust design calibrated to provide

maximum performance at high

RPM.

739-152D

739-152B



NOTE: The RPM ranges will

vary from model to model.



NOTE: If the servomotor cycles

three times and then shuts down,
the exhaust valve cables are not
adjusted correctly. The exhaust
valves may also be sticking.



adjustments may be done by the
snowmobile owner if qualified to
do so. If the owner does not feel
qualified, take the snowmobile to
an authorized Arctic Cat Snow-
mobile dealer for this service.
This service is at the discretion
and expense of the snowmobile
owner.

To adjust the APV System, use the

following prcedure:

1. Remove the cover from the

servo; then remove the actuat-

ing cables from the servo.

2. While holding the cable hous-

ing, lightly pull on one cable

end to remove any slack.

3. Measure the amount of exposed

cable from the cable housing to

the end of the cable.

0735-516

4. Repeat steps 2 and 3 for each

cable; then compare the mea-

surements.
