Summer

Storage

Priorto

storing

the

snowmobile

forthe

summer, it

must be

properly

serviced to prevent rusting and

component

deterioration.

Arctic

recommends

the

following

procedure

to prepare the

snowmo-

bile

for

storage.

1. Remove the seat cushion from the tunnel.

Wash the

cushion

with

damp

of any

part of the

engine

intake silencer.

3. Drain all fuel

from

the tank(s); then allow the

engine

to idle

until

it stops from lack of fuel.

4. Plug the hole in the

muffler

and air intake

silencer

with

clean rags.

5. Remove the spark plugs

from

the

cylinder

head. Pull the recoil until the piston reaches

TDC;

then

pour

one ounce of

Arctic

Cat

Engine Preservative or

snowmobile

oil into

the

spark

plug

hole. Repeat on

the

opposite

cylinder

and install spark plugs. Pull the

recoil several times.

6. Remove

the

the drive

clutch

and driven

pulley

for

wear.

Apply

light

coat

of oil on all steering

post

bushings, ski spindles and

the

front

and rear

arm pivot

bushings

of the skid frame.

10.

Lubricate

the

grease

fittings

on the rear arm

of the skid frame and the

lower

steering post

brackets

with

low-temperature

grease.

NOTE: Lube grease fittings on front arm if

so equipped.

11. Loosen the

track

tension

bolts

and rotate the

track

occasionally

during

the

storage

period.

12.

Tighten

all nuts,

bolts

and screws.

13. Clean and

polish

the hood,

console

and

chassis
