See pump installation gures. Remove four bolts by using wrench or socket. Remove air inlet
cover and air inlet gasket. Pilot valve group can be removed for control and maintenance.
You can remove pilot valve kit before removing the pump completely. Remove pilot valve piston.
Clean and control piston and o-rings for dirt, cut and wear. When necessary, replace o-rings and
piston with new ones. Remove the segment from case end and case from the valve body and
clean. Control case and o-rings for dirt, cut and wear.
When necessary, replace o-rings and case with new ones.Lubricate external surface and o-rings
of the case abundantly. Then place the ca se in valve body carefully. Pay attention that o-rings

o-rings of the case abundantly. Then place the case in valve body carefully.
Pay attention that o-rings are not cut while placing the case. Pay attention that pilot valve ends
are adjusted between piston pins while reinstalling pilot valve group to intermediate space gap.
Reinstall gasket, air inlet cover and bolts. Connect air inlet to the pump. The pump is ready to be
