SAFETY INFORMATION READ ALL SAFETY

INFORMATION BEFORE OPERATING THE EQUIPMENT

HAZARD: INJECTION INJURY

A high pressure paint stream produced by

this equipment can pierce the skin and underlying tissues, leading to serious injury

and possible amputation. SEE A PHYSICIAN IMMEDIATELY.

DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT! Injection can lead to amputation. See a physician immediately.

The maximum operating range of the gun is 2800 PSI/193BAR fluid pressure.

PREVENTION:

NEVER aim the gun at any part of the body.

NEVER allow any part of the body to touch the fluid stream. DO NOT allow body to touch a leak in the fluid hose.

NEVER put your hand in front of the gun. Gloves will not provide protection against an injection injury.

ALWAYS lock the gun trigger, shut the pump off, and release all pressure before servicing, cleaning the tip or guard, changing tip, or leaving unattended. Pressure will not be released by turning off the motor. The PRIME/SPRAY knob must be turned to PRIME to relieve the pressure. Refer to the PRESSURE RELIEF PROCEDURE (page 6) described in the pump manual.

ALWAYS keep the tip guard in place while spraying. The tip guard provides some protection but is mainly a warning device.

ALWAYS remove the spray tip before flushing or cleaning the system.

Paint hose can develop leaks from wear, kinking and abuse. A leak can inject material into the skin. Inspect the hose before each use.

NEVER use a spray gun without a working trigger lock and trigger guard in place.

All accessories must be rated at or above 2800 PSI/193 BAR. This includes spray tips, guns, extensions, and hose.

NOTE TO PHYSICIAN:

Injection into the skin is a traumatic injury. It is important to treat the injury as soon as possible. DO NOT delay treatment to research toxicity. Toxicity is a concern with some coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

HAZARD: HAZARDOUS VAPORS

Paints, solvents, insecticides, and other materials can be harmful if inhaled or come in contact with the body. Vapors can cause severe nausea, fainting, or poisoning.

PREVENTION:

• Use a respirator or mask if vapors can be inhaled. Read all instructions supplied with the mask to be sure it will provide the necessary protection.

Wear protective eyewear.

Wear protective clothing as required by coating manufacturer.

HAZARD: EXPLOSION OR FIRE

Solvent and paint fumes can explode or ignite.

Property damage and/or severe injury can occur.

PREVENTION:

Provide extensive exhaust and fresh air

introduction to keep the air within the spray area free from accumulation of flammable vapors.

Avoid all ignition sources such as static electric sparks, open flames, pilot lights, electrical appliances, and hot objects.

Connecting or disconnecting power cords or working light switches can make sparks.

Do not smoke in spray area.

Fire extinguisher must be present and in good working order.

Place paint pump at least 20 feet from the spray object in a well ventilated area (add more hose if necessary). Flammable vapors are often heavier than air. Floor area must be extremely well ventilated. The paint pump contains arcing parts that emit sparks and can ignite vapors.

The equipment and objects in and around the spray area must be properly grounded to prevent static sparks.

Use only conductive or grounded high pressure fluid hose. Gun must be grounded through hose connections.

Power cord must be connected to a grounded circuit.

Always flush unit into a separate metal container, at low pump pressure, with spray tip removed. Hold gun firmly against side of container to ground container and prevent static sparks.

Follow the material and solvent manufacturer's warnings and instructions.

Use extreme caution when using materials with a flashpoint below 70° F (21° C). Flashpoint is the temperature that a fluid can produce enough vapors to ignite.

Plastic can cause static sparks. Never hang plastic to enclose a spray area. Do not use plastic drop cloths when spraying flammable materials.

Use lowest possible pressure to flush equipment.

GAS ENGINE (WHERE APPLICABLE)

Always place pump outside of structure in fresh air. Keep all solvents away from the engine exhaust. Never fill fuel tank with a running or hot engine. Hot surface can ignite spilled fuel. Always attach ground wire from pump unit to a grounded object, such as a metal water pipe. Refer to enigine owner’s manual for complete safety information.

HAZARD: EXPLOSION HAZARD DUE TO

INCOMPATIBLE MATERIALS

Will cause property damage or severe injury.

PREVENTION:

Do not use materials containing bleach or chlorine.

Do not use halogenated hydrocarbon solvents such as bleach, mildewcide, methylene chloride and 1,1,1 - trichloroethane. They are not compatible with aluminum.

Contact your coating supplier about the compatibility of material with aluminum.

SAFETY INFORMATION READ ALL SAFETY

INFORMATION BEFORE OPERATING THE EQUIPMENT

HAZARD: GENERAL

Can cause severe injury or property damage.

PREVENTION:

Read all instructions and safety precautions before operating equipment.

Follow all appropriate local, state, and national codes governing ventilation, fire prevention, and operation.

The United States Government Safety Standards have been adopted under the Occupational Safety and Health Act (OSHA). These standards, particularly part 1910 of the General Standards and part 1926 of the Construction Standards should be consulted.

Use only manufacturer authorized parts. User assumes all risks and liabilities when using parts that do not meet the minimum specifications and safety requirements of the pump manufacturer.

Before each use, check all hoses for cuts, leaks, abrasion or bulging of cover. Check for damage or movement of couplings. Immediately replace the hose if any of these conditions exist. Never repair a paint hose. Replace it with another grounded high-pressure hose.

All hoses, swivels, guns, and accessories must be pressure rated at or above 2800PSI/193 BAR.

Do not spray outdoors on windy days.

Wear clothing to keep paint off skin and hair.

IMPORTANT ELECTRICAL INFORMATION

CAUTION

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A 14 or 12 gauge cord is recommended. If an extension cord is to be used outdoors, it must be marked with the suffix W-A after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

Do not use more than 100 feet of hose. If you need to paint further than 100 feet from your power source, use more extension cord, not more paint hose.

CAUTION

THE 1420 AND 1620 SERIES UNITS ARE PROVIDED WITH A NON-RESETABLE THERMAL OVERLOAD. THE 1720, 1920 AND 2120 SERIES UNITS ARE PROVIDED WITH A REPLACEABLE FUSE.

Always disconnect the motor from the power supply before working on the equipment.

The cause of the overload should be corrected before restarting. Take to Service Center.

GROUNDING INSTRUCTIONS

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING

Improper installation of the grounding plug can result in a risk of electric shock.

If repair or replacement of the cord or plug is necessary, do not connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin.

Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

This product is for use on a nominal 120 volt circuit and has a grounding plug that looks like the plug illustrated below. Make sure that the product is connected to an outlet having the same configuration as the plug.
