Preparation for Storage
Prior to storing the snowmobile, it is
extremely important that it be properly
serviced to prevent corrosion and compo-
nent deterioration. Yamaha recommends
the following procedure to prepare the
snowmobile for storage.
1. Clean the seat cushion with a Vinyl
Protectant and a damp cloth.
2. Clean the snowmobile thoroughly
by hosing dirt, oil, grass, and other
foreign matter from the undercar-
riage, tunnel, hood, and belly pan.
Allow the snowmobile to dry thor-
oughly. DO NOT get water into any
part of the engine.
3. Drain all gas from the gas tank.
Close the gas tank shut-off valve by
rotating it clockwise; then drain the
gasoline from the carburetor by
loosening the drain screw on the car-
buretor float chamber.
4. Plug the muffler outlet with a clean
cloth.
5. With the ignition key in the OFF
position:
A. Disconnect the high tension wire
from the spark plug; then remove
the spark plug.
B. Pour 10 ml (approximately two
teaspoons) of petroleum-based
oil into the spark plug hole; then
pull the recoil starter handle
slowly about five times.
C. Install the spark plug and con-
nect the high tension wire.
6. Remove the drive chain and clean
thoroughly in a solvent. Install drive
chain and lubricate with a dry,
graphite-based chain lubricant.
7. Change the oil; then clean the air fil-
ter.
8. Lubricate the spindles and the rear
suspension with an all-temperature
grease.
9. Tighten all screws, nuts, and cap
screws securely.
10. Make sure all rivets holding compo-
nents together are tight. Replace all
loose rivets.
11. Clean the hood, console, and chassis
with a soap and water mixture. DO
NOT USE SOLVENTS. THE PRO-
PELLANT WILL DAMAGE THE
FINISH.
12. If possible, store the snowmobile
indoors. Raise the rear of the snow-
mobile off the floor and block up the
rear end. Cover the snowmobile
with a snowmobile cover to protect
it from dirt and dust.
13. If the snowmobile must be stored
outdoors, block the entire snowmo-
bile off the ground and cover it with
a snowmobile cover to protect it
from dirt, dust, and rain.
CAUTION
Never crank the engine over without
grounding the spark plug. Damage
to the transistorized ignition may
result.
CAUTION
Avoid using a plastic cover as
moisture will collect on the snow-
mobile causing corrosion.
