NOTE:

Gas escapes when drilling.

-- Continue drilling until the tube inside is drilled through (approximately 25 mm deep).

-- Drill a second 6 mm hole -B- through the outer and inner shock absorber tubes.

-- Hold the shock absorber over an appropriate container for catching oil. Move the piston rod repeatedly through the entire stroke until no more oil flows out.
