CAUTION

Always hang the gun with its nozzle pointing down to
avoid having solvent run into the gun air passages.
Solvent in the gun air passages can cause poor
atomization and excessive current demands and can
damage the gun.

16. Clean the retaining nut, tip guard, air

cap and fluid tip with a soft brush
daily, minimum.

Clean the parts with a soft brush and replace them
if they are damaged. Be careful not to bend, dam-
age, or disengage the electrode wire.
