13.2.1 Disassembly
1. Remove plastic plug (0922).
2. Release the spring (0750) by turning the spring adjusting screw (0251) counter
clockwise using the retainer tool.

3. Remove screws (0523) by loosening them all one full turn.
If the cylinder (0220) stays in place (tap slowly with a plastic hammer on the
cylinder) the spring (0750) is fully released and the screws can be removed.
If the cylinder does not stay in place, first make sure that the spring will be
released.
4. All components can now be removed from the cylinder (0220) and from the pump
cover (0032).
13.2.2 Assembly
1. Screw the spring adjusting screw (0251) fully into the spring adjusting plate (0543).
2. If disassembled place the two pins (0563) in the spring adjusting plate (0543) and in
the piston (0230) respectively. Place the pin (0562) in the same way in the pump
cover (0032).
3. Place the piston (0230) together with the valve head (0200) by using the spacer
sleeve (0260) with the O-rings (0811). Before tightening the screw (0522) ensure that
the baseplate (0210) with O-ring (0808) is placed over the spacer sleeve (0260).
