2.
Loosen the washer plate using a 13 mm (0.5 in.) spanner.

Unscrew the washer plate while holding on to the module (the
spring force will force the module to detach from the piston).

Screw the washer plate back on to the module by hand. It is
recommended to add thread lock liquid prior to assembly.
NOTE!
It is important to tighten the washer plate with the correct torque, otherwise the washer plate may become loose or get
damaged!
