Handling Notes
WARNING:
This shock absorber is provided with a
separate type tank filled with high-
pressure nitrogen gas. To prevent the
danger of explosion, '"read and understand
the following information before handling
the shock absorber.
The manufacturer can not be held respon-
sible for property damage or personal in-
jury that may result from improper
handling.
1. Never tamper or attempt to dis-
assemble the cylinder or the tank.
Never tamper with the nut securing
the hose to the cylinder assembly;
otherwise, oil will spurt from the
cylinder due to the high pressure in
the nigrogen gas tank.
2. Never throw the shock absorber into
an open flame or other high heat. The
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 gas tank. A damaged gas tank
will impair the damping performance
or cause a malfunction.
4. Use care not to damage any part of
the hose. Any brake in the hose may
result in a spurt of oil under high-
pressure.
5. Take care not to scratch the contact
surface of the piston rod with the
cylinder; or oil could leak out.
6. Never attempt to remove the plug at
the bottom of the nigrogen gas tank.
It is very dangerous to remove the
plug.
7. Never attempt to remove the banjo
bolts where the hose attaches to the
monoshock and sub tank.
8. When scrapping the shock absorber,
follow the instructions on disposal.
9. Use only stardard shock absorber to
avoid damaging suspension and
frame.

Notes on Disposal (Yamaha dealers only)
Before disposing the shock absorber, be sure
to extract the nitrogen gas. To do so, drill a 2
or 3 mm (0.08 - 0.12 in) hole through the
tank at a position 25 - 30 mm (1.0 - 1.2 in)
from the bottom end of the tank. At this time,
wear eye protection to prevent eye damage
from escaping gas and/or metal chips.
