Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid
under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips.
1.Lock the spray gun trigger safety.
2.Close the pump air regulator. Close the
3.Unlock the gun trigger safety.
4.Hold a metal part of the spray gun firmly to a grounded metal waste container and trigger the gun to relieve the fluid pressure.
5.Lock the gun trigger safety.
6.Open the pump drain valve (required with your system) and leave it open until you are ready to spray again.
If you suspect that the spray tip or hose is clogged or that fluid pressure is not fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually. Clear the tip or hose obstruction.
WARNING
COMPONENT RUPTURE HAZARD Overpressurizing any component can result in rupture, fire, explosion, property damage, and serious injury. To reduce
the risk of overpressurizing, know the Maximum Working Pressure of the lowest rated component in your system, and limit the air to the pump so that you never exceed that pressure.
To determine the fluid output pressure using the air regulator reading, multiply the pump ratio by the air pressure you set on the regulator gauge. Example:
15 (:1) ratio x 100 psi air = 1500 psi fluid output
[15 (:1) ratio x 7 bar air = 105 bar fluid output]
WARNING
Never operate the pump with the warning plate
(20)or the identification plate (40) removed. These plates protect your fingers from pinching or am- putation by moving parts in the air motor.
Starting and Adjusting the Pump
1.With the air regulator (E) closed, open the bleed- type master air valve (F).
2.Connect the air hose.
3.Trigger the spray gun (N) into a grounded metal pail, making firm
4.Open the pump air regulator (E) slowly, just until the pump is running. When the pump is primed and all air has been pushed out of the lines, re- lease the spray gun trigger. With sufficient air supplied, the pump starts when the spray gun is triggered and shuts off when the trigger is re- leased.
5.Adjust the air regulator just until you get adequate flow from the spray gun. Always run the pump at the lowest speed necessary.
CAUTION
Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump acceler- ates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and lines with fluid, or flush it and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid lines. Use a pump runaway valve (K) to automatically shut off the pump if it starts to run too fast.
6.Read and follow the instructions supplied with each component in your system.
7.If the pump will be unattended for any period of time, or to shut off the system at the end of the work shift, always follow the Pressure Relief Procedure, at the left.
