Rear Shock Absorber
REAR SUSPENSION
F: DISPOSAL
CAUTION:
•Before handling the shock absorber, be sure
to wear goggles to protect eyes from gas, oil
and cutting powder.
•Do not disassemble the shock absorber or
place it into a fire.
•Drill a hole into shock absorbers in case of
discarding shock absorbers filled with gas.
1) Place the shock absorber on a level surface with
the piston rod fully expanded.
2) Make a hole into the specified position 30 mm
(1.18 in) deep using a drill with 2 — 3 mm (0.08 —
0.12 in) diameter.
(1) 40 mm (1.57 in)
