The shock absorber can be checked manually. However, a reliable check of shock absorbers is performed using a shock tester (with the shock absorber not removed) or on a special machine for checking shock absorbers.
Manual check
Remove the shock absorber.
Hold the shock absorber in the working position, stretch the shock absorber and compress it.

The shock absorber rod should move throughout its entire working stroke with the same resistance force and without jerking.
Press the piston rod all the way in and then release it. The piston rod should then extend again at a uniform speed.
If the shock absorber is functioning properly, traces of fluid are not a reason to replace it.
If there is a large fluid leak, replace the shock absorber.
Caution: The shock absorber must be degassed before disposal.
Install the shock absorber.
Disposal of shock absorber.
Extend the shock absorber piston rod fully and hold the shock absorber horizontally.
Before disposing of the shock absorber, drill a hole of approximately 3 mm in diameter in the place shown in the figure to release the gas.
Note: The gas released is colorless, odorless and non-toxic. When drilling, sawdust may fly off, so wear protective glasses.
