WARNING

This symbol indicates a potential hazard which may cause serious injury or loss of life. Important safety information will follow.

CAUTION

This symbol indicates a potential hazard to you or to the equipment. Important information that tells how to prevent damage to the equipment or how to avoid causes of minor injuries will follow.

NOTE: Notes give important information which should be given special attention.

WARNING

HAZARD: Injection injury - A high pressure 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 3000 PSI/207BAR 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 PRESSURE 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.

•The 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 trigger lock and trigger guard in place and in good working order.

•All accessories must be rated at or above 3000 PSI/207 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: EXPLOSION OR FIRE - Solvent and paint fumes can explode or ignite. Severe injury and/or property damage 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, 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 a minimum of 3 feet (preferably more) into a separate, well ventilated room from the spray object or 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 spark 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 engine owner’s manual for complete safety information.

HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE MATERIALS - Will cause severe injury or property damage.

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.

DANGER — 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. A temporary adapter which looks like the adapter illustrated in the figure below may be used to connect this plug to a 2 pole receptacle as shown if a properly grounded outlet is not available.

The temporary adapter should be used only until a properly grounded outlet as shown below can be installed by a qualified electrician. The green colored rigid ear, lug, or the grounding wire extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw.

Cover for grounded outlet box

Metal ScrewAdapter

Tab for

Grounding Screw

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.

NOTE: Do not use more than 50 feet of extension cord. If you need to paint further than 100 feet from your power source, use more paint hose, not more extension cord.

Spraying

NOTE: When spraying block filler, mastics or high solid coating, leave out the gun filter and high pressure filter screens.

Spraying Technique

The key to a good paint job is an even coating over the entire surface. This is done by using even strokes. Keep your arm moving at a constant speed and keep the spray gun at a constant distance from the surface. The best spraying distance is 10 to 12 inches between the spray tip and the surface.

Even coat throughout

Approximately 10 to 12 inches

Keep stroke smooth and at an even speed.

Keep the spray gun at right angles to the surface. This means moving your entire arm back and forth rather than just flexing your wrist.

Light Coat

Heavy Coat

Light Coat

Do not flex wrist while spraying.

Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other.

Approximately

10 to 12 inches

Right way

Wrong way

The spray gun should be triggered by turning it on and off with each stroke. This will save paint and avoid paint buildup at the end of the stroke. Do not trigger the gun during the middle of a stroke. This will result in an uneven spray and splotchy coverage.

Proper way to trigger the spray gun

Keep stroke

Approximately

even

10 to 12 inches

Start stroke

Pull trigger

Keep steady

Release trigger End stroke

Overlap each stroke by about 30%. This will ensure an even coating.

When you stop painting, lock the gun trigger lock, turn the pressure control knob counterclockwise to its lowest setting and set the PRIME/SPRAY valve to PRIME. Turn the motor switch to OFF and unplug the sprayer.

Practice

1.Be sure that the paint hose is free of kinks and clear of objects with sharp cutting edges.

2.Turn the pressure control knob counterclockwise to its to its lowest setting.

3.Turn the PRIME/SPRAY valve to SPRAY.

4.Turn the pressure control knob clockwise to its highest setting. The paint hose should stiffen as paint begins to flow through it.

5.Unlock the gun trigger lock.

6.Trigger the spray gun to bleed air out of the hose.

7.When paint reaches the spray tip, spray a test area to check the spray pattern.

8.Use the lowest pressure setting necessary to get a good spray pattern. If the

pressure is set too high, the	Good spray pattern
spray pattern will be too light.
If the pressure is set too low,
tailing will appear or the paint
will spatter out in gobs rather
than in a fine spray.	Paint tailing pattern
