FAQ


 Airless spray gun / pump repairing,review
.Cleaning, maintenance and storage
    1) After spraying, clean machine to avoid indurations and block-up. .
    2) Clean gun Filter after machine is used for some time. Discharge hose connector and hook plate, screw out gun handle, take out filter pistil and clean it, then fix them back. Change a new filter pistil when it is damaged. Wash the machine with relevant solvents for different paints.

Fig.6

    3) During spraying, check and clean suction-filter in time when paint blocks up. Usually clean it once after each use.
    4) To check timely if fixed parts are loosened and sealed parts have any leakage.
    5) Usually after three months usage of the machine, open pump cover and check if hydraulic oil is clean and enough. Add hydraulic oil when its in short; change hydraulic oil if it isnt clean. Clean oil-case of pump with diesel oil before changing hydraulic oil, and then add hydraulic oil to 85% of oil-case capacity.
    6) If you use this machine the second day, It is not necessary to clean it, dip the suction hose and tip into paint. For long storage, discharge the liquid in the machine, pack it well, store in dry and well-ventilated place, and dont be pressed by any articles.

 

.Trouble shootings
    The normal problems for machine are:
         1)The machine doesnt absorb liquid.
         2)It doesnt spray.
    Please try the following solution:
        1)Check if Inlet valve is in stickiness or leakage. If inlet valve is sticky, refer to fig.1. Push the dustpr-oof plug inside the inlet valve. To fill water into inlet valve and check whether its leaky. If its leaky, contact supplier to change it.

Fig.7

        2)Check whether the diaphragm is damaged. If it is damaged, oil goes out from outlet hose when it absorbs liquid, in additional, check if there is any hydraulic oil in the pump.

      Put this machine backward, loosen four fixed bolts on valve assembly, remove them and take out diaphragm to change.

      Its necessary to discharge air after changing diaphragm. Please follow these steps: Unscrew copper nut of pressure valve, turn on the motor repeatly till air is out. To check if the air is released, tighten copper nut of pressure valve, remove inlet valve and extend finger into the center hole of inlet valve, gently touch the diaphragm, if you can feel its vibrating, it means there is no air inside Otherwise, repeat the above.

.Other trouble shootings
    1.If the prime valve is leaky, circumfluence accrues in outlet hose when the valve is closed.
       1). Open and close spray valve in times to check whether inner parts of spray valve are locked.
       2).Discharge spray valve to check whether it is damaged. Take out gasket to inspect if the surface of it and hole bottom of spray valve are smooth. Change gasket if it isnt good. Contact supplier to maintain if hole bottom of spray vale isnt good. (Fig.9)
    2.Leakage between valve assembly and pump
       1)Check if the four bolts are loosening.
       2)Change valve assembly if seal grains behind it are damaged.(Fig.10)

    3. Contact the manufacturer if oil leakage in motor occurs, no hydraulic oil in pump or motor doesnt work.
