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

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 fluid 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 sprayer is 3200 PSI/221BAR 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 hand in front of the gun. Gloves will not provide protection against an injection injury.

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

•ALWAYS keep 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 3200 PSI/221 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 AND 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 electricity sparks, electrical appliances, flames, pilot lights, hot objects, and sparks from connecting and disconnecting power cords or working light switches.

•Do not smoke in spray area.

• Fire extinguisher must be present and in good working order.

• Place pump at least 20 feet (6.1 m) 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 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 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 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 at which a fluid can produce enough vapors to ignite.

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

• Use lowest possible pressure to flush equipment.

GAS ENGINE (WHERE APPLICABLE)

CAUTION

Always place sprayer outside of structure in fresh air. Keep all solvents away from engine exhaust. Never fill fuel tank with a running or hot engine. Hot surface can ignite spilled fuel.

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.

Grounded Outlet

Grounding Pin

Cover for grounded outlet box

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 12 gauge cord is recommended. If an extension cord is to be used outdoors, it must be marked with the suffix WA after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

Spraying

NOTE: When spraying block filler, mastics or high

solid coating, remove 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

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

even

Approximately

10 to 12 inches

Approximately

Heavy Coat

Start stroke End strokePull trigger Release triggerKeep steady

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 ON/OFF switch to the OFF position 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. Move the PRIME/SPRAY valve up to the SPRAY position.

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 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.
