TGC-555 – One quart capacity,
•Teflon
®
lined cup
TGC-545 – One quart capacity
TGC-536 – One pint capacity
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
Teflon
®
Cup - Only use a wooden or plastic paddle or mixer
for mixing material in the Teflon cup (7). A metal paddle or
mixer can scratch the Teflon lining.
Note
For Teflon
®
Lined Paint Cups, variation in the color of the Tef-
lon lining 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 Teflon because it provides the
best overall performance and maximum durability possible.
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
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.
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.
