3. 

Test movement of the valve by pushing on it 

from the  open end of the valve housing with the 
eraser end of a pencil or a  screwdriver. It should 
move  about  1/16  inch.  If  it  doesn't  move,  it  is 
probably  full  of  dry  paint  or  other  debris  and 
should be cleaned or replaced. 
 
 
 
 
 
 
 
 

4. 

Thoroughly  clean  the  valve  assembly  with 

solvent and brush 
 

5. 

A  properly  seated  valve  filled  with  water  and 

held vertically will not drip out the bottom of the 
valve.    If  you  have  properly  cleaned  the  valve 

and water drips out the bottom, the valve is worn 
and needs to be replaced 
 

6. 

Install cleaned or new valve in the pump block 

and then fill the valve with light oil or solvent. 
 

7. 

If  none  of  the  above  steps  work,  see 

Troubleshooting . 
 

Cleaning and Servicing Outlet Valve

 

It may be occasionally necessary to remove and 
clean  the  outlet  valve  or  replace  normal  wear 
parts inside the valve. 
 
 
 
 
 
  Outlet valve 
 
 
If  possible,  leave  the  copper  washer  under  the 
cap in place.    At least be sure to replace it with 
the same side up. (The top will show the imprint of 
the end cap, while the bottom should be perfectly 
flat to match seat in the pump casting.) See Paint 
Pump Assembly

 
 

Machine Mainterance

    

 

Cleaning the machine, parts every time after finished the paint work. 

 

Replace the 46# hydraulic oil inside the rear pump body after 300 hours of work to 

reduce equipment wear.

   

 

The diaphragm should be changed after each 400 hours works.

   

 

The screws connecting the front pump and the rear pump should be tightened diagonally.

 

 

Please check every parts have screw on the machine very tightly before using machine. Especially the suction tube 

and high pressure hose. 

 

 

Please notice that the inlet valve,  outlet  valve, diaphragm, are easily broken  parts,  if the machine has worked many 

times, and the machine have some problem about the pressure, suction, please check them first, then check again

 

 

Clean  the  motor  cooling  fan  protection  guard    and  the  finned

 

motor  casing  periodically  to  ensure  the  maximum 

cooling.
