Flush the Equipment
• Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Perform Pressure Relief Procedure , page 8.
2. Remove nozzle and soak in solvent.
3. Set pump to lowest possible fluid pressure, and start
pump.
4. Hold a metal part of the dispense valve (S) firmly to
a grounded metal pail. Trigger the dispense valve
until clean solvent dispenses.
5. Perform Pressure Relief Procedure , page 8.
Start and Adjust the Pump
1. Supply fluid to the pump, per the requirements of
your system.
2. Close the air regulator (F).
3. Open all air bleed valves (C, E).
4. Hold a metal part of the valve (S) firmly to the side of
a grounded metal pail and hold the trigger open.
5. Slowly open the air regulator until the pump starts.
6. Cycle the pump slowly until all air is pushed out and
the pump and hoses are fully primed.
7. Release the valve trigger and lock the trigger safety.
The pump should stall against pressure.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.
Keep hands and fingers away from the priming piston
(21) during operation and whenever the pump is
charged with air. The priming piston extends beyond
the intake housing (19) to pull material into the pump
and can amputate a hand or finger caught between it
and the intake housing. Follow the
Pressure Relief
Procedure on page 8, before checking, clearing, or
cleaning the priming piston.
