How to Clean the Spray Tip

and Clear a Spray Tip Obstruction

WARNING

To reduce the risk of fluid injection or splashing in the eyes or on the skin, do not hold a hand, body or rag in front of the spray tip when cleaning or checking a clogged tip. Point the gun toward the ground or into a waste container when checking to see if the spray tip is cleared.

Do not try to ªblow backº paint; this isnot an air spray gun.

Do not wipe fluid buildup off the gun or spray tip until pressure is relieved.

Cleaning During the Day

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5.

1.Relieve the pressure.

2.Clean the front of the tip frequently during the day to help reduce buildup. Also clean the tip and tip guard at the end of each work day. Use a solvent- soaked brush to clean the spray tip.

Clearing an Obstruction

If the spray tip clogs while spraying, immediately stop spraying, then:

Gun 235±460, 235±461, 235±462

± with standard tip guard

1.Lock the gun trigger safety, open the pressure drain valve.

2.Remove the spray tip and blow out the obstruction by applying air to the front of the spray tip. Or, let the spray tip and gun nozzle soak to dissolve the obstruction. If it won't dissolve, jar it out by tapping the back of the spray tip against a flat surface.

CAUTION

Never soak the entire gun in solvent. Prolonged exposure to solvent can ruin the packings.

Gun 235±463, 235±464, 238±591, 236±531 and 238±966 ± with RAC guard or Heavy Duty RAC guard

2.Unlock the gun trigger safety. Trigger the gun into a pail or onto the ground to remove the clog.

3.Lock the gun trigger safety. Rotate the tip handle to the spraying position.

4.If the tip is still clogged, lock the gun trigger safety, shut off the sprayer and disconnect the power source, and open the pressure drain valve to relieve pressure. Clean the spray tip as shown in manual 308±644, supplied with the RAC; or in manual 307±991, supplied with HD RAC.
