Valve Movement – Do not forcibly rotate the valve. If it will not move
freely, soak in solvent or remove the lid assembly from the cup and press
down on the top of the valve until it breaks free. The valve has free
travel vertically of about 1/8". This can be used to push out the gasket.

INSTALLATION
1.
Position yoke at right angle to gun body with vent hole in lid toward
rear and lever of cam (3) toward front of gun.
2.
Fasten cup lid assembly to gun by attaching nut (2), see Fig. 4, to
fluid inlet nipple on gun. Tighten nut with wrench only until snug.
3.
Strain material to be sprayed through a 60-90 mesh screen before
pouring into cup.
4.
Engage pins on cup into yoke and tighten yoke by moving lever of
cam clockwise.
MAINTENANCE
Lid Repair/Replacement:
1.
To replace a damaged part, use a 5/16" hex wrench to loosen and
remove adapter (1), nut (2), yoke & cam (3). Lid and tube assembly
are now loose for replacement.
2.
Replace damaged parts on the lid and tube assembly. The cam
lever should be located on opposite side of lid from valve (4).
3.
Apply sealant (Loctite #262) to the first two full threads of adapter
(1). Insert threaded end of adapter into open end of nut (2).
4.
Install adapter (1) and nut (2) in top of lid and tube assembly. Use
a 5/16" hex wrench to tighten firmly (10-12 foot pounds).
Valve and Lid Gasket Replacement:
1.
To remove a damaged valve (4) or lid gasket (5), press on top of
valve until it breaks free. The valve pushes the lid gasket from the
seat. The lid gasket may now be removed from the lid. Continue
pressing hard on the valve to remove it from the lid.
2.
Install replacement valve (4) through bottom of lid so that the valve
tab is toward center of lid. Snap in place. If necessary, use a plastic
mallet or screwdriver handle to tap the valve in place. Press the lid
gasket firmly in the lid using the end of a crescent wrench. Insert
the side with the black marks first.

CLEANING
Lid Underside
General: For routine cleaning, it is not necessary to remove the
lid gasket. It is not necessary or desirable to remove the valve for any
cleaning procedure. The valve can be depressed from the outside to
assist in removal of the gasket for gasket replacement or when cleaning
dried paint from the channel. The valve should not be forced past the
shoulder which retains it in the lid except for replacement.

IMMERSION
Since all materials in the cup are highly solvent resistant, the cup assembly
may be immersed for cleaning. Immersion should not exceed 24 hours.
The use of paint strippers should be avoided because strippers will af-
fect the aluminum as well as other non-metallic components. If the lid
gasket has become swollen from prolonged exposure to solvents, it will
return to its original size without loss of properties when allowed to dry.

Note
Always clean the cam lever (3) surfaces with clean solvent and a
brush. This will keep the cam lever functioning properly. Do not
lubricate the cam.
Minimize the amount of solvent atomized into the air.
Prevent possibility of damage to cup from excessive back pressure.
Reduce the force with which solvent is expelled from the vent.
Empty paint from cup and add small amount of clean solvent. The
amount required will vary with different coatings and solvents.
Shake cup to wash down inside surfaces. Then spray solvent at low
air pressure (15-20 psi) to flush out fluid passages.
Pour out solvent and add same amount of clean solvent.
gun and invert cup over solvent receptacle. Trigger with short bursts
to back flush vent channel. With valve in D/F position, solvent will
be expelled with force from the channel vent hole in lid.
solvent receptable. Trigger gun. Allow solvent to drip out channel
vent hole in lid for several seconds, or until clean solvent is seen.
• Do not probe through the channel vent hole at any time.
Do not probe through the valve slot hole while the valve
is in the D/F position. These holes are sealed by gasket
(5) and gasket damage could occur.
• Do not use abrasives such as a wire brush or steel wool
to clean the inside of the non-stick coating lined cup (7).
Damage to the non-stick surface could result.
