Cup Installation, Cleaning and Maintenance cont.
Cup Care and Cleaning
It is important to clean your cup after
every use.
First remove the check valve assembly
from the cup lid. Do not attempt to clean
the check valve assembly.
Before removing the cup lid from
the cup, be sure to relieve the cup
pressure through the relief valve.
Unscrew the cup lid and remove the
remaining material from the cup.
The spray gun and cup lid may remain
assembled if a gun washer is used.
Pull the diaphragm down approximately
1 inch from the lid before placing the
entire assembly into the gun washer.
If not using a gun washer, unscrew
the cup lid and remove the remaining
material from the cup and then rinse
with a suitable solvent.
WARNING
Gun washers are designed for
cleaning, not storage of spray
equipment. The 1/2 Pint cup may swell
if not promptly removed and dried.
Gasket Notes
These cups are pressure cups, therefore
the gasket must be in good condition.
The lid must be firmly seated on the cup
to prevent air and fluid leakage. Inspect
the gasket, lube the gasket channel, and
pay attention to the fit with each use.
Replace the gasket when necessary.
To extend the life the gasket: Clean and
dry gasket surface and store with cup
when not using.
To replace gasket:
1) Pull out the old gasket. Thoroughly
clean surface inside lid.
2) Inspect and clean lid of cup for dried
paint and burrs. Clean with solvent
or ultra-fine steel wool.
3) Place a small amount of petroleum
jelly on finger and lightly rub over
gasket channel inside lid. Carefully
install new gasket. Make sure that
the gasket is seated flat.
4) Tighten lid securely onto cup. Wait a
few minutes, then retighten. This will
ensure positive positioning of gasket
onto lid for optimum seal.
