Warnings

WARNINGS

Fire, Explosion, and Electric Shock Hazard

Improper grounding, poor air ventilation, open flames or sparks can cause a hazardous condition and

result in fire, explosion and serious injury.

• Provide fresh air ventilation to avoid buildup of flammable fumes from flushing fluids or coatings

being applied.

• Keep application area free of debris, including solvent, rags, and gasoline.

Equipment Misuse Hazard

Misuse can cause equipment to rupture or malfunction and cause serious injury.

• Read manuals, tags, and labels before operating equipment.

• Use equipment only for its intended purpose.

• Do not alter or modify extension tube, roller frame or use parts not designed for this equipment.

• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or

fluids containing such solvents in this or any other pressurized aluminum equipment. Such use

could result in a chemical reaction with the possibility of explosion.

Skin Injection Hazard

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like

just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
