- Drill ∅ 3 mm (standard type).
- Drill ∅ 6 mm (standard type).
- Safety glasses (standard type).
- Receiving vessel for catching oil (standard type).
- Pipe cutter, e.g. Stahlwille Express "150/3" (standard type).
Note: There are two options for removing shock absorbers.
Removal gas from front and rear gas-filled shock absorbers
Option A: Removing gas by drilling.
- I - Gas-filled shock absorber, front
- II - Gas-filled shock absorber, rear
Clamp the gas-filled shock absorber in a vertical position in a vice so that the piston points downwards.
Caution: When drilling, you must wear safety glasses.

Drill a ∅ 3 mm hole "arrow A" in the outer pipe of the shock absorber.
Note: Gas leaks when drilling.
Continue drilling until the inner shock absorber tube is also drilled through (depth about 25 mm).
Drill a second hole ∅ 6 mm "arrow B" in the outer and inner pipes of the shock absorber.
Holding the shock absorber over a tray to catch the oil, move the piston rod back and forth several times along the entire stroke until the oil leak completely stops.
Removal gas from front and rear gas-filled shock absorbers
Option B: Opening with a pipe cutter.
- I - Gas-filled shock absorber, front
- II - Gas-filled shock absorber, rear
Clamp the gas-filled shock absorber in a vertical position in a vice so that the piston points upward.
Caution: When drilling, you must wear safety glasses.

Drill a ∅ 3 mm "arrow" hole in the outer pipe of the shock absorber.
Note: Gas leaks when drilling.
Using a pipe cutter, such as Stahlwille Express "150/3", as shown in the figure, separate the outer pipe of the shock absorber.
Pull the piston rod upwards while holding the inner tube with a pipe wrench and pressing it down so that it remains in the outer tube when the piston rod is slowly pulled out.
Pull the piston rod out of the piston tube.
Empty the shock absorber pipe.
