CHASREAR SHOCK ABSORBER ASSEMBLY
HANDLING NOTE
WARNING
This rear shock absorber contains high-
pressure nitrogen gas. To prevent the dan-
ger of explosion, read and understand the
following information before handling the
shock absorber.
The manufacturer can not be held responsi-
ble for property damage or personal injury
that may result from improper handling.
1. Never tamper or attempt to open the
rear shock absorber.
2. Never throw the rear shock absorber
into an open flame or other high heat.
The rear shock absorber may explode
as a result of nitrogen gas expansion
and/or damage to the hose.
3. Be careful not to damage any part of
the rear shock absorber. A damaged
rear shock absorber will impair the
damping performance or cause a mal-
function.
4. Take care not to scratch the contact
surface of the piston rod with the cyl-
inder; or oil could leak out.
5. When scrapping the rear shock
absorber, follow the instruction on
disposal.
NOTES ON DISPOSAL (YAMAHA DEALERS
ONLY)
Gas pressure must be released before dispos-
ing of a rear shock absorber and gas cylinder.
To release the gas pressure, drill a 2 ~ 3-mm
(0.08 ~ 0.12-in) hole through the gas cylinder
at a point 12 mm (0.5 in) a from its end as
shown.
WARNING
Wear eye protection to prevent eye damage
from released gas or metal chips.
