When paint is sprayed, coat is not
covering.
Coat is going on too thin. Make sure gun is close enough to
surface.
Motor is hot and runs intermittently.
This is NOT a thermal overload con-
dition. Motor automatically shuts off
due to excessive heat. Damage can
occur if cause is not corrected.
Thermal Overload, page 4.
Vent holes in enclosure are plugged
or sprayer is covered.
Keep vent holes clear of obstructions
and overspray and keep sprayer
open to air.

heavy enough gauge.
Replace extension cord. Read

being used has excessive voltage.
Use electrical generator with a proper
voltage regulator. Sprayer requires
120VAC, 60 Hz, 1500-Watt genera-
tor.

sure with very small tip which causes
frequent motor starts and excessive
heat build up.

Free up circuit (unplug things), or use

• Plug in something that you know
is working to test extension cord.
• Replace extension cord.
