DISPOSAL
1. DISPOSE OF PNEUMATIC FRONT LH WITH SHOCK ABSORBER CYLINDER ASSEMBLY
(a) Fully extend the front 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.
