Husky HDS420 Do not immerse gaskets or spray gun body in solvents, Periodic CLEAN-UP, Storing

Maintenance (Continued)

4.Clean gaskets with a solvent soaked rag. To prevent equipment damage,

Do not immerse gaskets or spray gun body in solvents.

5.After using water to clean out water based paints or materials, spray mineral spirits through the gun to prevent corrosion.

6.Use a non-silicone oil on all moving parts when reassembling. Use Vaseline® or light grease on all threaded connections prior to storage.

7.Clean and flush gun thoroughly to neutralize any contaminants corrosive to the spray gun.

CLEANING A GUN USED WITH A PAINT TANK

! WARNING

Shut off the air supply to the tank and release the pressure in the tank.

1.Open the vent on the paint tank. If using an external mix air cap, loosen the cap slightly.

2.Reduce air pressure to 10-20 psi. Hold a piece of wadded cloth tightly around the air cap opening(s) and pull the trigger. The air will back up through the fluid tip and force the paint out of the hose and back into the tank.

3.Pour the paint from tank and use solvent and rags to clean.

4.Put enough solvent into the tank to wash the hose and gun thoroughly. Close the tank and spray from the gun until the solvent comes out clean.

5.Remove and blow out the material hose with compressed air to get rid of any trace of solvent in the hose.

When blowing out ! WARNING the hose, the open

end should be aimed away from any person to avoid blowing solvent into the eyes or on the skin causing possible injury.

PERIODIC CLEAN-UP

Due to dirty, lumpy paint etc., it may be necessary to inspect and clean the internal parts and the gun body.

1.Examine openings in air cap and fluid tip. If clogged, remove any o- rings and soak the air cap or fluid tip in solvent.

2.A brush or toothpick or something similar may be used to dislodge the dried paint from holes and passages.

NEVER USE METAL OBJECTS TO CLEAN PRECISELY DRILLED PASSAGES. DAMAGED PASSAGES WILL CAUSE IMPROPER SPRAYING.

3.Remove and check the adjusting needle for excessive wear at the tip and straightness.

IMPORTANT: If the needle tip is worn more on one side than the other, either the needle is bent or the gun body has been dropped or knocked out-of-line. There are no adjustments that can be made to a bent gun body. Test the needle by rolling on a flat surface. Replace if necessary.

4.Check and replace any damaged o-rings and seals. O-rings and seals can be wiped clean but not soaked in solvent.

5.Unscrew packing nuts and replace the packing ONLY if a leak will not stop when the nut is tightened. Do not over-tighten a packing nut because this will restrict movement of the needle.

6.Reassemble in reverse order of these steps and use a non-silicone oil on moving parts. Apply Vaseline® or light grease on threaded joints and hose connections.

STORING

1.When not using spray gun, turn the fluid control knob counterclockwise to open reducing spring tension on needle fluid tip.

2.Spray gun MUST BE well cleaned and lightly lubricated.
