Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion 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 or on warning labels, 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.

WARNING

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

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 MSDSs 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.

• Always wear chemically impermeable gloves when spraying, dispensing, or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

Wear appropriate protective equipment when in the work area to help prevent serious injury, including

eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment includes but is

not limited to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer

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

332078C 5

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.

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 com-

ponent. 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.

• 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.

WARNING

Warnings

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.

SPLATTER HAZARD

Hot or toxic fluid can cause serious injury if splashed in the eyes or on skin. During blow off of platen,

splatter may occur.

• Use minimum air pressure when removing platen from drum.

General Information

Pressure Settings

All pressure settings are controlled through the Operator

Interface Panel. Refer to Screen 2, page 27, to set the

feed station pressure.

Fluid Pressure Gauges

All A and B material pressure gauges should read

the same as each other during normal operation of

the machine.

Solvents

These are rarely used with modern 1:1 silicones. For

cleaning, methylene chloride or white spirits solvent are

used. Methylene chloride is recommended because it is

non-flammable.

NOTICE

To avoid machine damage, do not exceed 120 psi

(0.8 MPa, 8.3 bar) air pressure at the machine inlet.

To avoid serious injury, do not use flammable

solvents for cleaning.
