Basic Troubleshooting
10 309477F
Spray pattern is inconsistent or
is leaving stripes Pressure is set too low Turn pressure control knob clockwise to increase
pressure.
Spray tip is worn beyond
capability of sprayer Replace spray tip.
Pressure is set at maximum
but cannot achieve a good
spray pattern Spray tip is too big for sprayer Select smaller spray tip.
Spray tip is worn beyond
capability of sprayer Replace spray tip.
Extension cord is too long or
not heavy enough gauge Replace extension cord. Grounding and
Electrical Requirements, page 7.
Spray gun fluid filter is clogged Clean or replace spray gun fluid filter.
InstaClean fluid filter is clogged
(XR9 only) Clean or replace InstaClean fluid filter.
Inlet screen is clogged Clean debris off inlet screen.
Pump valves are worn See Low or Fluctuating Output, page 15.
Motor is hot and runs
intermittently.
This is NOT a thermal overload
condition. Motor automatically
shuts off due to excessive heat.
Damage can occur if cause is
not corrected.
Thermal Overload, page 7. Vent holes in enclosure are
plugged or sprayer is covered Keep vent holes clear of obstructions and
overspray and keep sprayer open to air.
Extension cord is too long or
not a heavy enough gauge Replace extension cord. See Grounding and
Electrical Requirements, page 7.
Unregulated electrical
generator being used has
excessive voltage Use electrical generator with a proper voltage
regulator. Sprayer requires 220-240 VAC, 50/60
Hz, 1500-Watt generator.
Sprayer was operated at high
pressure with very small tip
which causes frequent motor
starts and excessive heat build
up Decrease pressure setting or increase tip size.
Building circuit breaker opens
after sprayer operates for 5 to
10 minutes. Too many appliances are
plugged in on same circuit. Free up circuit (unplug things), or use a less busy
circuit.
Sprayer electrical cord is
damaged. Check broken insulation or wires. Replace
electrical cord if damaged.
Fan pattern varies dramatically
while spraying
OR
Sprayer does not turn on
promptly when resuming
spraying Pressure control switch is worn
and causing excessive
pressure variation Replace pressure control knob using Pressure
Control Switch Kit, page 18.
Cannot trigger spray gun Spray gun trigger safety lever is
in SAFETY ON position Rotate trigger safety lever to SAFETY OFF
position.
Spray comes out of spray gun
in two thick streams Reversible spray tip is in
UNCLOG position Rotate arrow-shaped handle on spray tip so it
points forward in SPRAY position.
Paint is coming out of pressure
control switch Pressure control switch is worn Replace pressure control using Pressure Control
Switch Kit, page 18.
Spray-PRIME valve actuates
automatically relieving
pressure through drain tube System is over pressurizing See Excessive Pressure Build Up, page 17.
Paint leaks down outside of
pump Pump packings are worn Replace pump packings. See Pump Service,
page 20.
