WARNING

INJECTION HAZARD

Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause a serious injury.

DFluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi- cal attention.

DDo not point the spray gun at anyone or at any part of the body.

DDo not put hand or fingers over the spray tip.

DDo not stop or deflect fluid leaks with your hand, body, glove, or rag.

WARNING

INJECTION HAZARD

To reduce the risk of property damage or serious injury, including fluid injection,

which could be caused by component rupture or unrelieved fluid pressure,

DA fluid drain valve is required in your system to assist in relieving fluid pressure in the displace- ment pump, hose and gun; triggering the gun to relieve pressure may not be sufficient.

DThe bleed-type master air valve is required in your system to relieve air trapped between this valve and the pump after the air regulator is closed. Trapped air can cause the pump to cycle unexpectedly, which could result in seri- ous injury.

1.Install a bleed-type master air valve on the pump air supply line, downstream of the pump air regula- tor, to shut off air to the pump.

2.Install a fluid filter and fluid drain valve close to the pump's fluid outlet. The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.

3.Install a fluid pressure regulator to control fluid pressure to the gun.

4.Install a fluid shutoff valve to shut off the fluid supply to the gun.

5.Connect a grounded fluid hose to the gun fluid inlet.

6.Without the tip installed, start the pump or sprayer and flush it according to the pump or sprayer instructions. Prime the pump or sprayer with the fluid you are going to spray.

Continued on the next page.

NOTE: The gun will leak if the tip gasket (16) is not installed.

10.Disconnect the harness (7) clip from the gun ring (5).

11.Place the harness (7) over one shoulder and across the chest. Fasten the belt around the waist. Adjust the length of the shoulder strap as needed.

12.Check that the handle grip (9) is in a comfortable position. To adjust it, loosen the screw (3) and nut (1), rotate the grip to a good position, and firmly tighten the screw and nut.

Ground the System

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding could cause static sparking, which could cause a fire or explosion. To reduce the risk of property damage or serious injury, follow the grounding instructions below.

The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects which must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground.

1.Pump/Sprayer: Ground the pump/sprayer by connecting a ground wire and clamp between the pump/sprayer and a true earth ground as in- structed in the equipment's instruction manual.

2.Air compressor: Ground according to the manufacturer recommendations.

3.Air and fluid hoses: Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of your air and fluid hoses at least once a week. If the resistance exceeds the recommended limits, replace the hose immedi- ately.

4.Pole gun: Ground the gun by connecting it to a properly grounded fluid hose and pump.

5.Fluid supply container: Ground it according to local code.

6.Object being sprayed: Ground it according to local code.

7.All solvent pails used when flushing: Ground them according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or card- board, which interrupts the grounding continuity.

8.To maintain grounding continuity when flush- ing or relieving pressure: Always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

Pressure Relief Procedure

WARNING

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 tip.

1.Fully close the gun ON/OFF lever (B). See Fig. 2.

2.Slide the safety ring (20) over the gun ON/OFF lever.

3.Close the pump air regulator.

4.Close the bleed-type master air valve (required in the system).

5.Slide the safety ring off the gun ON/OFF lever.

6.Hold a metal part of the gun firmly to the side of a grounded metal waste container and open the gun ON/OFF lever to relieve the fluid pressure.

7.Fully close the gun ON/OFF lever, and slide the safety ring over the lever.

8.Open the pump drain valve (required in the sys- tem) to help relieve fluid pressure in the displace- ment pump. Triggering the gun to relieve pressure may not be sufficient. Have a container ready to catch the drainage.

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

10.If you suspect that the spray tip or hose is com- pletely clogged or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen the coupling completely. Now clear the tip or hose obstruction.
