EMEDIES

The pump overload
cutout trips
(red indicator light on the
switchboard comes on)

No material comes
out of the spray gun.

Material tends to drip from the
spray gun during operation.

Material flows from the spray gun
intermittently during operation.

Clamp too tight.

Working pressure too high.

Incorrect supply voltage.

Plugged hose.

Encrusted material or pebble
obstructing the passage.

Spray tip hole too small.

Incorrectly adjusted stator.

Spray tip or nozzle hole too large.

Bent air hose or clogged air nozzle.

• Loosen clamp.

• Change the mix or reduce hose

length or use hoses with larger
diameter.

• Have the line voltage checked (page 12).
If necessary obtain an independent

generating set with minimum
capacity of:

25 kVA (version without mixer)
or 30 kVA (version with mixer)

• Incorrect mix,
change the mix.
• Delays in applications; shorten

pause times.

• Incorrectly adjusted stator; adjust.

• Clean the spray tip and, if necessary,

the gun.

• Replace the spray tip.

• Adjust the stator.

• Replace with a spray tip or nozzle

having a smaller hole.

• Check the air hose and the nozzle

for obstructions.
