Troubleshooting
Problem
Pressure set at maximum, but cannot
achieve good spray pattern.
Sprayed paint runs down wall or sags.
Sprayed paint is not covering.
Pattern is inconsistent or leaving
stripes.
HINT:
Thin paint slightly with solvent/water.
Motor is hot and runs intermittently.
This is a Thermal Overload condition.
Motor will automatically shut off due to
excessive heat. Damage can occur if
cause is not corrected. Startup Hazard
After Thermal Overload, Warnings,
page 7.

Cause
Tip is worn beyond capability of
sprayer.
Gun filter clogged.
Inlet screen clogged.
Pump valves worn.
Extension cord too log or not heavy
enough gauge.
Going on too thick
Going on too thin.
Pressure set too low.
Spray tip worn beyond capability of
sprayer.
Vent hole ins shroud are clogged or
sprayer is covered.
Extension cord too long or not heavy
enough gauge.
Unregulated electrical generator being
used has excessive voltage.
Sprayer was operated at high pressure
with small tip, causing frequent motor
starts and excessive heat build up.
Solution
Replace tip.
Clean or replace gun filter, page 40.
Clean debris off inlet screen.
Check for worn pump valves:
1 Prime sprayer with paint.
2 Trigger gun momentarily. When trigger is released,
pump should cycle and stop.
3 If pump continues to cycle, pump valves may be worn.
4 Return sprayer to Graco/M
center.
Replace cord, Grounding and Electrical Requirements,
page10.
Move gun faster.
Use tip with smaller hole size.
Use tip with wider fan.
Move gun away from surface.
Move gun slower.
Use tip with larger hole size.
Use tip with narrower fan.
Move gun closer to surface.
Turn pressure control knob right to increase pressure.
Replace tip.
Clear vent holes.
Replace cord. Grounding and Electrical Requirements,
page 10.
Use electrical generator with proper voltage regulator. Sprayer
requires 220-240, VAC 50/60 Hz.
Decrease pressure setting or increase tip size.
Move sprayer to cooler location.
