tip is clogged. continued pull on the lever with a clogged tip will
over-pressurize the unit, causing it to shut down.

gun holder to clean the tip.
1. Place a sheet of cardboard or small
bucket under the spray gun to catch
the paint.
2. Rotate the tip 180º so that the arrow
on the tip handle is pointing opposite
the spray direction.
NOTE: If the tip is difficult to rotate, relieve pressure by 1)
slowly turning the PRImE/SPRAy knob to PRImE,
2) unlock the spray gun, and 3) squeeze the spray
lever. Release the lever, lock the spray gun, and try
rotating the spray tip again.
