Troubleshooting

Check all possible remedies in the Troubleshooting
Chart before disassembling the gun.

Spray Pattern Troubleshooting

Some spray pattern problems are caused by the improper balance between air and fluid.

WARNING

Electric Shock Hazard

Installing and servicing this equipment
requires access to parts which may cause
an electric shock or other serious injury if

the work is not performed properly. Do not install or
repair this equipment unless you are trained and
qualified.

WARNING

Skin Injection Hazard

To reduce the risk of a fluid injection injury,
always follow the Pressure Relief Proce-
dure on page 18 before doing any mainte-
nance or service on this gun or system.

Problem

Cause

Solution

Fluttering or spitting spray.

No fluid.

Refill supply.

Air in fluid supply.

Check fluid source. Refill.

Irregular pattern.

Fluid buildup; partially plugged tip.

Clean. See page 26.

Worn/damaged tip or air cap holes.

Clean or replace.

Pattern pushed to one side; air cap
gets dirty.

Air cap holes plugged.

Clean. See page 26.

Tails in pattern.

Atomization air pressure too low.

Increase atomization air pressure.

Fluid pressure too low.

Increase.

Fluid buildup on air cap/tip guard.

Atomization air pressure too high.

Decrease.

Fluid pressure too low.

Increase.
