IMPORTANT: To ensure that this equipment
reaches you in first class condition, protective
coatings, rust inhibitors, etc., have been used.
Flush all equipment through with a suitable
solvent before use to remove these agents from
the material passages.
CAUTION: The cup is under pressure.
Disconnect the air supply and release the
pressure in the cup assembly before removing
the cup from the lid assembly or disconnecting
the gun or the material hose. Never allow the cup
to lay on its side or fall over when it contains
material.
Controls (See Figure 1)

Safety Valve (14): The safety valve limits the
maximum air pressure to the cup. If the
safety valve does not work properly, over
pressurisation may occur and cause the cup
to rupture or explode. Occasionally pull the
ring on the safety valve and make sure that it
operates freely. If the valve is stuck or does
not operate smoothly it must be replaced
with a valve having the same rating. Never
attempt to adjust or dismantle the safety
valve.

Regulator (15): Controls the pressure of the
coating material in the cup. To increase the

When pressure is set push knob in to lock.
Pressure Relief Valve (6): Vents the air
pressure in the cup. To open, turn valve
counter-clockwise. CAUTION Do not
unscrew the pressure relief valve (6)
completely when relieving the pressure as it
may have sufficient air pressure to eject the
valve from the lid creating a hazard.
Pressure Gauge (8): Indicates the air
pressure in the cup. Do not attempt to
