Point A: 40—50 mm {1.6—1.9 in}
WARNING:
Whenever drilling into a rear shock absorber, wear protective eye wear. The gas in the rear shock absorber is pressurized, and could spray metal chips into the eyes and face when drilling.
1. Clamp a rear shock absorber on a flat surface or with the piston pointing downwards.
2. Drill a 2—3 mm {0.08—0.11 in} hole at a point A from the bottom of the tube, so that the gas can escape.
Point A: 40—50 mm {1.6—1.9 in}
3. Turn the hole downwards.
4. The oil can be collected by moving the piston rod several times up and down and cutting the tube at the end.
5. Dispose of waste oil according to the waste disposal law.
