Valve replacement

 Unscrew the pump head fixing screws.

Take out the pump head and valve.

 Replace the old valve with new one.

Always check the mating points and fit 
the valve and the pump head in place.

 Supply air into the pump head unit.

Check the air flows from the inlet to the outlet.

 

Push down the diaphragm until it bottoms out.

Secure the pump head unit onto the bracket with the fixing screws by 
1.96N•m.

NOTE

•  Do not loosen the bracket-motor fixing screws during maintenance work.
•  Contact your nearest distributor for the replacement of the connecting rod, eccentric 

shaft and the motor.
