WARNING

Be sure all operators of this equipment read, understand, and follow the warnings and instructions in the manuals for all painting equipment and this manual.

AVOID POWER LINES

Avoid contact with any power lines! Contact with power lines could cause extremely serious bodily injury, including burns or electrocution.

PRESSURE RELIEF PROCEDURE

To reduce the risk of serious bodily injury from fluid injection, splashing in the eyes, injury from moving parts, or property damage, always follow this procedure whenever you stop painting, and before checking, changing or repairing any part of the paint system.

1.

Engage the dispensing valve/gun safety latch.

ELECTRICAL GROUNDING

To reduce the risk of static sparking which can cause fire or explosion and result in serious bodily injury and property damage, be sure your entire system and the object you are painting are properly grounded.

Read and follow all grounding instructions in your separate pump and paint gun instruction manual, and follow all local codes regarding electrical grounding.

AVOID OVERPRESSURIZING EQUIPMENT

Operate your pump at the lowest pressure needed for sufficient paint supply to the roller. The pressure is safer at lower pressures, and the paint is easier to control.

2.

Shut off the power to the pump.

3.

Open the fluid drain valve (required in high pressure systems to help relieve pressure).

4.

Disengage the dispensing valve/gun safety device and trigger the gun.

5.

Engage the dispensing valve/gun safety device.

This pressure relief procedure may be different than the one supplied with your pump or paint dispensing valve/gun. Use this procedure ONLY when using this Pressure Roller Equipment.

At other times, relieve the pressure exactly as stated in your separate pump or paint dispensing valve/gun instruction manual.

Do not attempt to modify the roller frame or to use parts which are not designed to be used with this equipment. Modifying parts can cause them to overpressurize which can result in component rupture or explosion, and cause serious bodily injury, including fluid injection and splashing in the eyes, or property damage.

Never exceed the maximum working pressure of the lowest rated component in your system, including this pressure roller frame, the dispensing valve/gun, extension tubes, hoses and pump/sprayer. Overpressurizing equipment can cause component rupture, fire or explosion and result in serious bodily injury, including injection, splashing in the eyes and property damage.
