WARNING

INJECTION HAZARD

To reduce the risk of an injection injury or splashing fluid in the eyes or on the skin:

DFollow the Pressure Relief Procedure on page 7 before cleaning, removing, or installing a spray tip and whenever you are instructed to relieve pressure.

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

CAUTION

To avoid damaging the gun:

DNever immerse the gun in solvent as this could damage packings and allow solvent in the air passages.

DDo not use fluids containing halogenated hydrocarbons to clean the gun body as HHC is not compatible with aluminum.

DMethylene Chloride is not recommended as a flushing or cleaning solvent with this gun or any device with nylon or aluminum components.

DDo not use metal tools to clean holes in the air cap or spray tip.

NOTE: Clean the front of the tip frequently during the day to help reduce buildup. AA RAC style tips require more frequent cleaning.

1.Relieve the pressure as instructed on page 7.

2.Clean the outside of the gun and the tip guard with a soft cloth dampened with compatible solvent.

3.To avoid damaging the spray tip and air cap, clean them with a compatible solvent and soft brush. To clean the air cap passages, use a soft brush or other soft tool. Dry the parts with an air blow gun.

4.If using an in-line filter, remove and clean it thoroughly in a compatible solvent.

5.Clean the system's fluid filter and air line filter.

Check the Diffuser-seat Operation Weekly

WARNING

INJECTION HAZARD

The gun diffuser-seat breaks up spray when the gun is sprayed without the spray tip installed, such as during flush-

ing. This reduces the risk of an injection injury. Check the diffuser-seat operation weekly.

1.Relieve the pressure as instructed on page 7.

2.Remove the tip guard and spray tip.

3.Start the pump and operate it at its lowest pres- sure.

4.Hold a metal part of the gun firmly against a grounded metal waste container, and trigger the gun. See Fig. 7. If the fluid coming from the gun is not diffused into an irregular stream, replace the diffuser-seat immediately.
