Fault
Possible Cause
Solution
The pump does not cycle whether the
spray gun is triggered (without tip) or the
drain valve / screw is opened.
1. Air tap lock is closed.
2. High-pressure filter is clogged.
3. Air motor is defect.
1. Open the air tap lock.
2. Clean or replace the filter insert.
3. Repair the air motor according to the
spare parts list - Contact
Customer Service if necessary.
Pump cycles, but no material reaches the
tip.
.
1. Suction sieve is clogged.
2. Suction hose is blocked.
3. Bottom valve ball does not rise (stuck).
4. Bottom valve does not close.
1. Clean the sieve.
2. Replace the hose.
3 - Trigger the spray gun without tip.
- Open the high-pressure filter drain
valve/screw
- Lightly hit the bottom valve from the
side (hammer).
- Remove the suction assembly and
press on the ball from below using a
peg or screwdriver until loose.
4. Remove the bottom valve and clean
the ball and seat thoroughly.
Pump cycles but does not stop with the
spray gun is closed.
Packing and/or valve worn.
Replace.
Pump cycles evenly but the required ope-
rating pressure can not be reached
1. Air supply / pressure is too low.
2. Tip (new) is too big.
3. Tip is worn (too big).
4. Air motor is frozen (runs too slow).
1. Increase the inbound air pressure with
the regulator and check the diameter
of the inbound air hose.
2. Use a smaller tip or larger pump.
3. Replace.
4. - If possible, reduce the inbound air
pressure.
- If not already in use, mount an air
maintenance unit with oiler. Fill the
oiler with anti-freeze (Glysantine)
and set it according to the instruc-
tions in the User's Handbook: Ave-
rage setting: 1 drop every 10 cycles
Pump cycles unevenly (different stroke
speeds on the upward and downward
strokes) and the required spray pressure
can not be reached..
1. The viscosity of the coating is too high
(suction loss).
2. Suction assembly leakage (spray jet
fluctuates).
3. Bottom valve leaks (pump only stops
on the upwards stroke when the spray
gun is closed).
4. Piston valve leaks (pump only stops on
the downwards stroke when the spray
gun is closed).
5. Upper or lower packings leak (wear).
1. - Thin the coating.
- Use a larger pump.
2. Check the seal of all suction assembly
connections and replace if necessary.
3. Remove the bottom valve and clean
the ball and seat thoroughly.
4. Clean the ball and seat in the dual pi-
ston and replace if necessary.
5. Replace.
Coatings material spills out of the air motor
anti-vaccum hole.
Packings are worn.
Replace.
Note:
Do not close or block the anti-vaccum
hole!
