MPFHVLP SPRAY GUN

Cleaning and Maintenance

WARNING

Follow Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing equipment. Read warnings, page 2.

CAUTION

•Do not submerge gun in solvent. Solvent dissolves lubri- cant, dries out packings, and may clog air passages.

•Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern.

•Use a compatible solvent.

•Gun can be cleaned in a gun washer.

Clean air line filters as directed by the manufacturer.

Volatile Organic Compounds (VOC) Regulation

In certain states, spraying solvents that release VOC’s into the atmosphere when cleaning a spray gun is prohibited. To comply with these air quality laws you must use a cleaning method that prevents the escape of VOC vapors into the atmosphere. See Compliant Cleaning Methods below.

Compliant Cleaning Methods

•Place spray gun in a gun washer that completely encloses the gun and components during cleaning, rinsing, and draining.

•Spray solvent through the spray gun into a closed gun cleaning station.

Cleaning Gun

Refer to Compliant Cleaning Methods to comply with air quality laws if applicable.

1.Follow Flushing procedure, page 3.

2.Use a rag moistened in solvent to wipe outside of gun.

3.Blow dry gun inside and out. Lubricate gun as described in Spray Gun Maintenance.

Cleaning Nozzle and Air Cap

CAUTION

•Trigger gun whenever you tighten or remove nozzle to avoid damaging needle seat and nozzle.

•Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern.

To clean the air cap and nozzle, remove and soak them in a compatible cleaning solution. Clean them and front of gun with a soft-bristle brush dipped into compatible solvent. Do not use a wire brush or metal tools. To clean out air cap holes, use a soft implement, such as a toothpick.

Spray Gun Maintenance

•Frequently lubricate the gun moving parts with a drop of non-silicone oil (part no. 8255).

•Do not disassemble the spray gun if you are having a spray pattern problem. Check Troubleshooting, page 5, for infor- mation on how to correct the problem.

•Check for fluid leakage. Tighten fittings or replace equip- ment as needed.
