Description
The Model 288776 2-quart (1.9-liter) pressure
cup is designed to be used with any pressure
feed manual spray gun when more than 1
quart of fluid will be used. Pressure cups pro-
vide a better degree of control over atomizing
air and fluid pressure than siphon feed equip-
ment. The Model 288776 enables you to spray
a wider range of refinish materials and has a
full 2-quart (1.9 liter) capacity when needed.
The regulator assembly controls pressure of
fluid in the cup from 0-50 psi (0.35 MPa, 3.5
bar). The manual pressure relief valve allows
air pressure to bleed from cup.
Set-Up
1. Connect air hose to air inlet of gun and to
air outlet on cup regulator as shown.
2. Connect fluid hose to fluid inlet of gun and
to cup fluid outlet as shown.
3. Connect handle to top of cup as shown.
4. It is best for the air supply line to pass
through a Graco Air Control Unit to filter
dirt from the air and extract water and oil.
Connect the air supply hose to the air inlet
fitting on cup regulator.
Note: Follow the manufacturer’s directions for the mixing and preparation of material. Strain
material using a fine mesh screen to prevent the entry of foreign matter and the clogging of fluid
passageways.
Never tamper with the automatic pressure
relief valve (6b). The automatic relief valve
limits the maximum air pressure entering the
cup. If the relief valve does not work properly,
over-pressurization may occur and cause the
cup to rupture or explode. Air pressure in the
cup must never exceed 50 psi (0.35 MPa, 3.5
bar).
Always disconnect cup assembly from air sup-
ply and relieve pressure in cup (open manual
relief valve counter-clockwise) before installing
or removing canister from lid assembly.
