Take caution not to damage the seal groove of the cover at this time.

As shown in Fig. 17, hold the piston seal with one hand and push it into the groove so that the piston
seal can be lifted off and pulled out without using a precision screwdriver.
The groove of the piston is deep, so if the piston seal is removed with a precision screwdriver, it might
be damaged.
