NOTE: Some jumper cables may be
the same color but the clamps or ends
will be color-coded red and black.
7. Attach one clamp of the negative
jumper cable (black) to the negative
(-) terminal (3) of the good battery
(B); then attach the other clamp of
the negative (black) jumper cable (4)
to an unpainted metal surface (A) on
the engine or frame well away from
the dead battery and fuel system
components.
! WARNING
Never make the final connection to a
battery as a spark could ignite hydro-
gen gases causing an explosion of
the battery resulting in acid burns or
blindness.
8. Stand well away from the dead bat-
tery and start the vehicle with the
good battery. Allow the vehicle to
run for several minutes applying
some charge to the dead battery.
9. Start the snowmobile with the dead
battery and allow it to run for several
minutes before disconnecting the
jumper cables.
10. Remove the jumper cables in oppo-
site order of hook-up (4, 3, 2, 1). Be
careful not to short cables against
bare metal.
NOTE: Have the battery and elec-
trical system checked prior to oper-
ating the snowmobile again.
Drive Clutch and Driven
Clutch
The drive clutch and driven clutch do not
require lubrication; therefore, no special
maintenance is required by the snowmo-
bile owner except for periodic cleaning.
When operating the snowmobile at high
altitudes, it may be necessary to change
certain component parts of the drive
clutch and/or the driven clutch. See an
0744-527
authorized Yamaha Snowmobile dealer
for further information.
If you become aware of higher than
normal
unusual shift patterns, see your
authorized
dealer immediately. Do not operate
the snowmobile until the clutches
have been serviced and/or repaired.
DO NOT attempt to service the drive
clutch and driven clutch. The drive
clutch and driven clutch must be ser-
viced
by
Snowmobile dealer only.
Drive Clutch/Driven
Clutch Alignment
The alignment between the drive clutch and
driven clutch is set at the factory. Normally,
no adjustment is necessary as long as neither
the drive clutch nor the driven clutch is
removed or disassembled. However, if pre-
mature drive belt wear is experienced or if
the drive belt turns over, the drive clutch/
driven clutch alignment must be checked.
Take the snowmobile to an authorized
Yamaha Snowmobile dealer for this service.
If not under warranty, this service is at the
discretion and expense of the snowmobile
owner.
Fuel Pump
The fuel pump is designed to provide
adequate amount of gas to the
at all throttle settings. If a fuel delivery
problem is suspected, take the snowmo-
bile to an authorized Yamaha Snowmo-
bile dealer. If not under warranty, this
service is at the discretion and expense of
the snowmobile owner.
