Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To

reduce the risk of an injury from accidental spray from the gun, 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 nozzle.

1.Lock the gun trigger safety.

2.Shut off the power supply to the pump and close any bleed-type master air valves in the air supply.

3.Unlock the gun trigger safety.

4.Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun into the pail to relieve pressure.

5.Lock the gun trigger safety.

6.Open the pump fluid drain valve (required in the system), having a container ready to catch the drainage.

7.Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Now clear the tip or hose.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD Proper electrical grounding is essential to reduce the risk of fire or explosion which can result in serious injury and property damage. Also read FIRE OR EXPLOSION HAZARD on page 3.

1.Pump or Sprayer: as instructed in your separate pump or sprayer manual.

2.Air compressor or hydraulic power supply: accord- ing to local code.

3.Fluid hoses: use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.

4.Spray gun: obtain grounding through connection to a properly grounded fluid hose and sprayer or pump.

5.Fluid supply container: according to local code.

6.Object being sprayed: according to local code.

7.All solvent pails used when flushing, according to local code. Use only metal pails, which are con- ductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which inter- rupts the grounding continuity.

8.To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a metal pail, then trigger the gun.
