Warnings

WARNING

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.

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.

• 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. Do not use pail liners unless they

are antistatic or conductive.

• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

ELECTRIC SHOCK HAZARD

This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock.

• Turn off and disconnect power cord before servicing equipment.

• Connect only to grounded electrical outlets.

• Use only 3-wire extension cords.

• Ensure ground prongs are intact on power and extension cords.

• Do not expose to rain. Store indoors.

SKIN INJECTION HAZARD

High-pressure fluid from dispensing device, 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.

• Engage trigger lock when not dispensing.

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

• Do not put your hand over the fluid outlet.

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

• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or

servicing equipment.

• Tighten all fluid connections before operating the equipment.

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

Warnings

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 from distributor or retailer.

• Do not leave the work area while equipment is energized or under pressure.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.

• 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. Alterations or modifications may void agency approvals and create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• 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.

PLASTIC PARTS CLEANING SOLVENT HAZARD

Many solvents can degrade plastic parts and cause them to fail, which could cause serious injury or property damage.

• Use only compatible water-based solvents to clean plastic structural or pressure-containing parts.

• See Technical Data in this and all other equipment instruction manuals. Read fluid and solvent

manufacturer’s MSDSs and recommendations.

MOVING PARTS HAZARD

Moving parts can pinch, cut 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 and disconnect all power sources.

Preparation

Pressure Relief Procedure

1. Turn Main Power Switch (A) OFF.

2. Turn fluid flow regulator (K) all the way down to reduce pressure.

3. Open gun air valve (aa).

4. Trigger gun, spraying material back into hopper (C).

Grounding and Electric Requirements

The sprayer must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for the electrical current.

• The sprayer cord includes a grounding wire with an appropriate grounding prong.

• The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

• Do not modify plug! If it will not fit in outlet, have grounded outlet installed by a qualified electrician.

Ground

ti4295a

• Sprayer model electric requirements are provided on page 3.

Extension Cords

• Only use an extension cord

with an undamaged 3-prong plug.

• For up to 100 ft (30.48 m) cord, use 3-wire, 12 AWG (2.5 mm

)

minimum.

310645S 7

Preparation

Auxiliary Air Compressor

• Use Auxiliary Air Hookup Kit 287328 when addi-

tional atomization air is necessary.

NOTICE

Attaching auxiliary air to sprayer without using the Auxiliary Air Hookup Kit will damage sprayer.

Generators

7500 W (7.5 KW) minimum.

Tips for Using Generators

• Before running sprayer, make sure it is at room tem-

perature. This will reduce startup current.

• Run generator at full throttle.

Hose Lengths

• The system comes with a twin line hose set consist-

ing of a 1 in. ID x 25 ft (25 mm x 7.6 m) material hose and a 3/8 in. ID air hose. Additional hose sections can be added. Total final length of hose used should not exceed 100 feet in length.

• The 24X140 model comes with a separate 1 in. ID x 15 ft (25 mm x 4.6 m) material hose and 3/8 in. x 15 ft air hose.

NOTICE

Sprayer air hose fitting can get hot! Allow sprayer to cool down 5 minutes before removing air hose.
