OPERATION
Open Vent Mode "O"- To operate in the open vent mode, rotate the
valve with a screwdriver or coin so that the hole in the valve slot is
aligned with the "O" on the lid. See Figure 2.
If the valve slot hole should plug while operating in the "O" vent
mode, use a pointed tool such as a nail or drill bit to probe through
the valve slot hole to clear away the obstruction.

Figure 2 – Open Vent Mode
Drip Free Mode "D/F" – To operate in the drip free mode, rotate the
valve with a screwdriver or coin so that the hole in the valve slot is
aligned with the "D/F" on the lid. See Fig. 3
These drip free suction cups have a unique, two position valve which
permits selection of either a drip free spraying mode or a conventional
open vent mode.
In the drip free position, air is directed through the vent in the lid
to a channel beneath the lid gasket before entering the cup at the
valve. This allows the cup to be tilted when full without dripping
paint through the vent. The cup can also be inverted while spraying
without leaking.
The open position isolates the channel and opens a direct vent into
the cup.
The position of the valve is indicated by alignment of the hole in the
valve slot with the marks cast on the lid. These positions are identified
as "O" for vent open and "D/F" for Drip Free.
Note
Non-stick Coating Lined Cup - Only use a wooden or plastic
paddle or mixer for mixing material in the cup (7). A metal
paddle or mixer can scratch the non-stick coating.
Note
For Non-stick Coating Lined Paint Cups, variation in the color
of the non-stick coating is normal. This variation is the result
of the normal production process used with this type of coating. We have selected this particular grade of non-stick coating
because it provides the best overall performance and maximum
durability possible.
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 a gasket and gasket
damage could result. See Figs. 2 & 3.
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.

HAZARD SAFEGUARDS
Fire
Solvent Spray
CAUSE
Solvents and coatings can be highly
flammable or combustible, especially
when sprayed.
During cleaning and flushing, solvents
can be forcefully expelled from fluid
and air passages. Some solvents can
cause eye injury or irritation.
Important information that tells how to prevent
damage to equipment

Inhaling Toxic Substances Certain materials may be harmful if
Chlorinated solvents, such as 1, 1, 1
- Trichloroethane and Methylene Chloride (sometimes called methyl chloride)
can chemically react with the aluminum used in most spray equipment,
and these cups, to produce an explosion hazard. The TLC-555, TGC-545 and
TGC-536 are aluminum.

INSTALLATION
Cleaning Procedures:
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
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.
1. Empty paint from cup and add small amount of clean solvent. The
amount required will vary with different coatings and solvents.
2. Shake cup to wash down inside surfaces. Then spray solvent at
low air pressure (15-20 psi) to flush out fluid passages.
3. Pour out solvent and add same amount of clean solvent.
4a. Again, shake cup. Loosen air cap. Hold a folded cloth over front
of 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.
Alternative to Step 4a.
4b. Shut off air to gun. With valve in D/F position, invert cup over
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.
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 affect 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.
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.
Air Pressure: Always clean with reduced air pressure. An air pressure
no greater than 15 to 20 psi will allow quick and thorough cleaning
of the cup and gun and at the same time will:
1. Minimize the amount of solvent atomized into the air.
2. Prevent possibility of damage to cup from excessive back pressure.
3. Reduce the force with which solvent is expelled from the vent.
