Troubleshooting
Mechanics / paint stage
Pump output is low 14.
O-ring in pump is worn or
damaged
15.
Material residues on the inlet
valve ball
16.
Pressure set too low
17.
Large pressure drop in hose
with heavy materials
14.
Replace O-ring.
15.
Clean inlet valve.
16.
Increase pressure.
17.
Use a larger diameter hose and/or reduce the overall
length of the hose. A hose exceeding 30 m in length with
a ¼" diameter significantly reduces the performance of
the sprayer. Use a 3/8" hose for optimum performance
(minimum length of 15 m).
Fault Cause Remedy
Excessive paint leakage
into packing nut
1.
Packing nut loose
2.
The packing seals are worn
or damaged
3.
The piston rod is worn or
damaged
1.
Remove the spacer of the packing seal. Tighten the
packing nut to stop the leakage.
2.
Replace seals.
3.
Replace rod.
Fault Cause Remedy
Material pulsates from
the gun
1.
Air in the device or hose
2.
Nozzle is partially clogged
3.
Content of material container
is low or empty
1.
Check all fittings for leaks and tighten if necessary. Red-
uce the motor speed via the potentiometer and operate
the pump as slowly as possible during the suction pro-
cess.
2.
Clean nozzle.
3.
Refill the material container. Operate the pump; check
the material container frequently to prevent the pump
from running dry.
