Preparation after Storage
Taking the snowmobile out of storage
and correctly preparing it for another sea-
son will assure many miles and hours of
trouble-free snowmobiling. Yamaha rec-
ommends the following procedure:
1. Clean the snowmobile thoroughly.
Polish the exterior of the snowmobile.
2. Clean the engine. Remove the cloth
from the exhaust system. Check
exhaust system and air-intake
silencer for obstructions.
3. Inspect all control wires and cables
for signs of wear or fraying. Replace
if necessary. Use cable ties or tape to
route wires and cables away from
hot or rotating parts.
4. Inspect the drive belt for cracks and
tears. Check belt specifications.
Replace if damaged or worn. Install
the drive belt.
NOTE: If the old belt is worn but
in reasonable condition, retain it
with the snowmobile as a spare in
case of emergency.
5. Tighten all nuts, bolts, and cap
screws making sure all nuts, bolts,
and cap screws are tightened
securely.
6. If not done during preparation for
storage, lubricate the rear suspen-
sion with low temperature grease.
7. Check the coolant level and all cool-
ant hoses and connections for deteri-
oration or cracks. Add properly
mixed coolant as necessary.
8. Charge the battery until fully
charged; then connect the battery
cables making sure to connect the
positive cable first. Test the electric
start system.
9. Inspect the entire brake system, all
controls, headlight, taillight, brake-
light, ski wear bars, and headlight
aim; adjust or replace as necessary.
10. Adjust the track to the proper tension
and alignment.
Noise level and vibration level
Noise level (77/311/EEC):
96 dB(A)@4375 r/min
Uncertainty of measurement:
3.0 dB(A)
A-weighted sound power level:
103 dB(A)@4375 r/min
Uncertainty of measurement:
3.0 dB(A)
Vibration on seat (EN1032, ISO 5008):
Not exceed 0.7 m/s²
Uncertainty of measurement:
1.5 m/s²
Vibration on handlebar (EN1032, ISO
5008):
Not exceed 4.2 m/s²
Uncertainty of measurement:
0.4 m/s²
The figures quoted are emission levels
and are not necessarily safe working lev-
els. Whilst there is a correlation between
the emission and exposure levels, this
cannot be used reliably to determine
whether or not further precautions are
required. Factors that influence the actual
level of exposure of work-force include
the characteristics of the work room, the
other sources of noise, etc. i.e. the num-
ber of machines and other adjacent pro-
cesses, and the length of time for which
an operator is exposed to the noise. Also
the permissible exposure level can vary
from country. This information, however,
will enable the user of the machine to
make a better evaluation of the hazard
and risk.
