DISPOSAL

1. DISPOSE OF PNEUMATIC CYLINDER WITH REAR SHOCK ABSORBER ASSEMBLY
(a) Fully extend the rear shock absorber rod.
(b) Using a drill, make a hole in the cylinder somewhere between A and B shown in the illustration to discharge the gas inside.

CAUTION: Be careful as the cylinder is a high-pressure gas type which is at a higher pressure than normal shock absorbers. Also be careful with high temperatures as the cylinder's pressure becomes even higher.

NOTICE: The gas is colorless, odorless and harmless.
