1. Remove the valve (Fig. 201/1) and washer (Fig. 201/2).
→ Air pressure bleeds off.
2. Place a suitable tool in the groove of the cover and unscrew the
cover (Fig. 201/3).
3. Check the diaphragm (Fig. 201/4) and exchange the diaphragm
if it is defective.
4. If required, clean the cover.
5. Re-fit the cover, washer and valve.
6. Recharge the pressure reservoir to 3 bar of air pressure.
If the pump does not run smoothly, the air pressure in the pressure
reservoir can vary. The air pressure should be in the range of the
spray pressure.
