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

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

the rear shock absorber. A damaged
rear shock absorber will impair the
damping performance or cause a mal-
function.

surface of the piston rod with the cyl-
inder; or oil could leak out.
