Warning

Warning

The following are general warning related to the safe setup, use, grounding, maintenance and repair of this equipment. Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appearing in the body of the manual refer to these general warnings. When these symbols appear throughout the manual, refer back to these pages for a description of the specific hazard.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

Use equipment only in well ventilated area.

• Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable and can ignite or explode if spilled on hot surface.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

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

Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.

Ground all equipment in the work area. See Grounding instructions.

Use only grounded hoses.

Hold gun firmly to side of grounded pail when triggering into pail.

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.

SKIN INJECTION HAZARD

High-pressurefluid 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.

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

Do not put your hand over the spray tip.

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

Do not spray without tip guard and trigger guard installed.

Engage trigger lock when not spraying.

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

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

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

Tighten all fluid connections before operating the equipment.

Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

RECOIL HAZARD

Brace yourself; gun may recoil when triggered and cause you to fall, which could cause serious injury.

Warning

WARNING

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 Manufacturer’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.

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

Keep clear of moving parts.

Do not operate equipment with protective guards or covers removed.

Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

PRESSURIZED ALUMINUM PARTS HAZARD

Do not use 1,1,1-trichloroethane,methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.

SUCTION HAZARD

Never place hands near the pump fluid inlet when pump is operating or pressurized. Powerful suction could cause serious injury.

CARBON MONOXIDE HAZARD

Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon monoxide can cause death. Do not operate in an enclosed area.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

Read MSDS’s to know the specific hazards of the fluids you are using.

Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

BURN HAZARD

Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

Operation

Pressure Relief Procedure

System pressure must be manually relieved to prevent it from starting or spraying accidentally. Fluid under high pressure can be injected into the skin and cause serious injury. To reduce risk of injury from injection, follow this procedure whenever you are instructed to relieve pressure, stop spraying, service equipment or install or clean spray tip. Read warnings, page 4.

1 Set pump valve OFF. Turn engine OFF.

TI A

2Turn pressure to lowest setting. Trigger gun into pail to relieve pressure.

Operation

General Repair Information

Hydraulic system and engine may become very hot during operation and could burn skin if touched. Flammable materials spilled on hot, bare motor could cause fire or explosion. Have belt guard in place during operation to reduce risk of pinching or loss of fingers.

Install belt guard before operation of sprayer and replace if damaged. Belt guard reduces risk of pinching and loss of fingers.

To reduce risk of serious injury,:

Keep all screws, nuts, washers, etc. removed during repair procedures. These parts usually are not provided with replacement kits.

Test repairs after problems are corrected.

If sprayer does not operate properly, review repair procedure to verify you did it correctly. See Troubleshooting, page7.

Do not touch moving parts with fingers or tools while testing repair.

3 Open prime valve (vertical).

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 tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Then clean tip and hose.

Grounding

Ground sprayer with grounding clamp to earth ground for safe sprayer operation.
