WARNING

FIRE AND EXPLOSION HAZARD

When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be aware that flammable fumes can ignite or explode. To help prevent fire and explosion:

•Use equipment only in well ventilated area.

•Eliminate all ignition sources, such as cigarettes and portable electric lamps.

•Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.

•Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

•Ground all equipment in the work area.

•Use only grounded hoses.

•If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

•Keep a working fire extinguisher in the work area.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

•Do not operate the unit when fatigued or under the influence of drugs or alcohol.

•Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

•Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS forms from distributor or retailer.

•Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu- facturer’s replacement parts only.

•Do not alter or modify equipment.

•Use equipment only for its intended purpose. Call your distributor for information.

•Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

•Do not kink or over bend hoses or use hoses to pull equipment.

•Keep children and animals away from work area.

•Comply with all applicable safety regulations.

SKIN INJECTION HAZARD

High-pressure fluid from dispense valve, 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.

•Do not point dispense valve at anyone or at any part of the body.

•Do not put your hand over the end of the dispense nozzle.

•Do not stop or deflect leaks with your hand, body, glove, or rag.

•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
