SAFETY PRECAUTIONS
This manual contains information which must be read and understood before using the equipment. When you come to an area which has one of the following symbols, pay particular attention and make certain to heed the safeguard.
WARNING
Important safety information indicates a hazard which may cause serious injury or loss of life.
CAUTION
Important information that tells how to prevent damage to equipment or how to avoid causes of minor injuries.
Notes: Gives important information which should be given special attention.
CAUTION
THIS UNIT IS PROVIDED WITH A THERMALLY PROTECTED AUTOMATIC RESET. IF AN OVERLOAD OCCURS THE THERMALLY PROTECTED AUTOMATIC RESET DISCONNECTS THE MOTOR FROM THE POWER SUPPLY.
Motor will restart without warning when protector automatically resets.
• Always disconnect motor from power supply before working on equipment.
• When thermally protected automatic reset disconnects the motor from the power supply, relieve pressure by turning priming valve to "prime" A .
• Turn ON-OFF switch OFF.
CAUTION: THE CAUSE OF THE OVERLOAD SHOULD BE CORRECTED BEFORE RESTARTING. (SEE TROUBLE SHOOTING )

WARNING
HAZARD

Injection Injury - A high pressure stream of paint pro-

duced by this equipment can pierce the skin and underlying tissues, leading to serious injury and pos­sible amputation.
PREVENTION
• Maximum operating range of the gun - 2500 PSI fluid pressure.
NEVER aim the gun at any part of the body.
NEVER allow any part of the body to come in contact with the fluid stream. DO NOT come in contact with a fluid stream created by 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 the gun trigger,shut fluid pump off and release all pressure before servicing, cleaning tip guard, changing tips, or leaving unattended. Simply turning off the electrical power will not release pressure in the system. The Prime Spray Valve must be turned to the prime A position to relieve the pressure.
ALWAYS have the tip guard in place while spraying. The tip guard provides some protection against injection injuries but is mainly a warning device.
DO NOT TREAT AS A SIMPLE CUT! Injection­can lead to amputation. See a physician im­mediately.
NOTE TO PHYSICIAN: Injection into the skin is a traumatic injury. It is important to treat the injury surgically 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.
ALWAYS remove spray tip before flushing or cleaning the system.
• Paint hose can develop leaks from wear, kinking, abuse etc. A leak is capable of injecting material into the skin. The paint hose should be inspected before each use.
NEVER use a spray gun which does not have a trigger lock and trigger guard in place and in working order.
• All accessories must be rated at or above 2500 P.S.I. (Includes spray tips, guns, extensions, and hose).
• In case of skin injection see physician immediately.
Refer to Cleaning Instructions.

WARNING
HAZARD PREVENTION

Explosion or fire - Solvent and paint fumes can explode or

ignite, causing property damage and or severe injury.
• Exhaust and fresh air introduction must be provided to keep the air within the spray area free from accumulation of flammable vapors.
• Avoid all ignition sources such as static electricity sparks, open flames such as pilot lights, hot objects such as cigarettes, and sparks from connecting and disconnect­ing power cords and working light switches.
• Fire extinguishing equipment must be present and in working order.
• Keep the pump away from spray area to avoid solvent and paint fumes. The pump contains arcing parts which emit sparks.
• Do not spray paints and other inflammable fluids which have a flashpoint below 21° C (70° F). (Flashpoint is the temperature at which a fluid begins giving off a sufficient amount of flammable vapor that could ignite when ex­posed to a flame or spark.)
• High velocity flow of material through equipment may develop static electricity. The equipment being used, and objects in and around the spray area must be properly grounded to prevent static discharge and sparks.
• Use only conductive or grounded high pressure fluid hoses for airless applications. Be sure that gun is grounded through hose connections.
• Power cord must be connected to a grounded circuit. (See proper grounding instructions.)
• Follow the material and solvent manufacturer's safety precautions and warnings.
• WHEN FLUSHING EQUIPMENT use lowest possible pressure.

other materials may be harmful if inhaled causing se­vere nausea, fainting, or poisoning.
General - May cause property damage or severe injury.
PREVENTION
DO NOT USE BLEACH.
DO NOT use halogenated hydrocarbon solvents.
• Halogenated hydrocarbon solvents such as methylene chloride and 1,1,1 - Trichlorethane are not compatible with aluminum and may cause an explosion. If unsure of a material’s compatibility with aluminum, contact your coatings supplier.
• Use a respirator or mask whenever there is a chance that vapors may be inhaled. Read all instructions with the mask to insure that it will provide the necessary protection against the inhalation of harmful vapors.
• Read all instructions and safety precautions before oper­ating.
• Comply with all appropriate local, state and national codes governing ventilation, fire prevention, and opera­tion.
• The United States Government Safety Standards have been adopted under Occupational Safety and Health Act. These standards, particularly the General Standards, Part 1910 and construction Standard, Part 1926, should be consulted.
• This high pressure airless pump is designed to be used with authorized parts only. When using this pump with parts that do not comply with the minimum specifications and safety devices of the pump manufacturer, the user assumes all risks and liabilities.
• Before each use, check all hoses for cuts, leaks, abrasion or bulging of cover or damage or movement of couplings. If any of these conditions exist, replace the hose immedi­ately. Never repair a paint hose. Replace it with another grounded hose.
• All hoses, swivels, guns, and accessories used with this unit must be pressure rated at or above 2500 PSI.
DO NOT spray on windy days.

Extension Cord
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.
NOTE: More than 100 feet of extension cord is not recommended. Use more paint hose, not more extension cord. Shorter extension cords will assure maximum electrical power for proper operation.
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.
Improper installation of the
WARNING
grounding plug can result in a risk of electric shock.
This product is for use on a nominal 120 volt circuit, and has a grounding plug that looks like plug illustrated in Figure 2 (A) below. A temporary adapter which looks like the adapter illustrated in Figure 2 (B) and (C), may be used to connect this plug to a 2 pole receptacle as shown in Figure 2 (B) if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet as shown in Figure 2 (A) can be installed by a qualified electrician. The green colored rigid ear lug, or the like 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.

5. Unlock SPRAY GUN TRIGGER LOCK by turning lock down toward the bottom of the handle. Figure 4
6. Trigger spray gun to bleed air out of hose.
7. When paint reaches spray tip, spray a test area to check spray pattern. See Figure 23.
8. Use the lowest pressure setting necessary to get a good spray pattern. If pressure is too high, material is over-atomized. If pressure is too low, tailing will appear or paint will spatter out in gobs rather than in a fine spray. See Figure 24. Most latex paints and stains will require very high pressure, which is why the sprayer is built to deliver up to 2,500 psi when needed.
GOOD SPRAY PATTERN
4. Turn PRESSURE CONTROL KNOB completely clockwise to maximum pressure, Figure 21. Paint
should then begin to flow into the paint hose, causing it to stiffen.
Figure 24 - Paint Tailing Pattern
15
SPRAYING
SPRAYING TECHNIQUE
1. The key to a good paint job is an even coating over the entire surface. With spray painting, this is done by using even strokes, with your arm moving at a con­stant speed and keeping the spray gun a constant distance from the surface.
2. In most cases, the best spraying distance is 10 to 12 inches between the spray tip and the surface.
Even Coat on Work Throughout
Approximately
Approximatley
10 to 12 Inches
10 to 12 Inches
3. As much as possible, 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. See Figures 25 and 26.
4. Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other. See Figure 27.

5. The spray gun should be triggered off at the end of each stroke and on again at the beginning of the next. This avoids paint buildup at the end of the stroke which may result in runs and sags. Triggering at the end of the stroke also saves paint and results in a better looking job. See Figure 28.

6. Overlap each stroke by about 30%. This will assure a paint coating that is uniform across the work. One way to do this is to point the spray tip at the edge of the last stroke before triggering the gun on.
If Spray Tip Becomes Clogged
The spray gun is equipped with a reversible tip which enables you to quickly and effectively blow out any particles of old paint or other contaminants that may obstruct the paint flow through the tip. If the spray pattern becomes distorted or stops completely while the gun is triggered on, follow these steps.
1. Release the trigger and put on the safety lock. See Figure 4.
2. Rotate the reversible tip cylinder arrow 180° so the point of the arrow is toward the rear of the gun. Figure
29.
7. When taking a short break from painting (up to 1 hr.), lock the spray gun trigger OFF, reduce pressure to its minimum (zero) setting and set the unit to prime A . Turn sprayer off and unplug. Refer to Pressure Relief Procedure.
8. If you expect to be gone more than 1 hour follow the short term clean up procedure.
Figure 29 - Reverse Tip
3. Unlock the trigger and squeeze it open, pointing the gun at a scrap piece of wood or cardboard. This allows pressure in the paint hose to blow out the obstruction. When the nozzle is clean, paint will come out in a straight, high pressure stream.
4. Release the trigger and re-lock it. Figure 4
5. Reverse the tip so the arrow points forward again.
6. Unlock the trigger and resume spraying.

Continued from page 17
SPRAYING
Cleaning The Spray Gun Filter
The spray gun includes a filter to catch particles before they reach the spray tip. If this filter becomes clogged or obstructed it will reduce the flow of paint, changing the spray pattern and possibly damaging the filter.
This filter must be cleaned at least daily and perhaps even every four hours with certain types of latex materials.
If the filter is not cleaned at the proper time, it will plug from the top down. When there is about 1 inch of filter that isn't plugged, the heavy flow of paint will blow pin holes in the filter. See Figure 30. This in turn will allow unwanted particles to get into the spray tip, causing spray tip to clog.
Top of Filter
Pin Hole
Figure 30 - Gun Filter Cleaning.
To clean the filter during the painting process:
1. Turn spray PRESSURE CONTROL KNOB to mini­mum setting and turn PRIMING KNOB to PRIME A . This will bleed off the pressure in the paint hose and
filter. Trigger gun to be sure pressure is gone. Refer to Pressure Relief Procedure.
2. Remove spray gun from hose using two adjustable wrenches. See Figure 10
3. Unscrew filter housing, using adjustable wrench on the nut at the bottom of the housing.
6. Insert the top of the filter (Figure 30) into the gun body fitting under the tip of the spray gun. See Figure 31.

Filter Housing
Suction Set Screen
The screen at the bottom of the suction set may also need cleaning periodically. Check it every time you change paint buckets. Remove screen by pulling it out of the retainer with a pliers. Clean the screen with water or solvent and a soft-bristle brush, if needed.
4. Remove filter being sure not to lose the spring and sealing washer which is located in the bottom of the filter housing.
5. Clean filter thoroughly (or put in a new filter). To clean the filter, swish it in water or the type of solvent appropriate to the paint you are using. If this isn’t sufficient, use a natural or nylon bristle brush dipped in the appropriate solvent or water. Do not use a wire brush or any sharp instrument.

1. Be sure sprayer is off.
2. Using a 27 millimeter socket or box end wrench, remove the inlet valve assembly.
Remove
Inlet Valve
Figure 45- Removing Inlet Valve
3. Test movement of the valve by pushing on it from the open end of the valve housing with the eraser end of a pencil or a screwdriver. It should move about 1/16 inch. If it doesn't move, it is probably full of dry paint or other debris and should be cleaned or replaced.
NOTE: The inlet valve must be oiled after every job. This will reduce or eliminate priming problems the next time the sprayer is used. See Figure 43.
4. Thoroughly clean the valve assembly with solvent and brush.
5. A properly seated valve filled with water and held vertically will not drip out the bottom of the valve. If you have properly cleaned the valve and water drips out the bottom, the valve is worn and needs to be replaced.
6. Install cleaned or new valve in the pump block and then fill the valve with light oil or solvent.
7. If none of the above steps work, see Troubleshoot­ing.
Cleaning and Servicing Outlet Valve
It may be occasionally necessary to remove and clean the outlet valve or replace normal wear parts inside the valve. See Figures 47 and Figure 48.
1. Remove outlet cap with adjustable wrench.

MAINTENANCE
CLEANING VALVES
2. If possible, leave the copper washer under the cap in place. At least be sure to replace it with the same side up. (The top will show the imprint of the end cap, while the bottom should be perfectly flat to match seat in the pump casting.) See Paint Pump Assem­bly Parts Diagram,Item 4 for replacement part num­ber.
3. With a wire hook or tweezers, remove the small spring inside the valve. Replace if broken, or worn or clean as necessary. See Paint Pump Assembly Parts Diagram, Item 4 for replacement part number. This spring is manufactured to a very specific ten­sion, so do not put in an unauthorized subsitute. Proper spring length is 7-1/2 coils.
4. Using a six-millimeter allen wrench, remove the seat and ball assembly. See Figure 48.
5. Clean parts thoroughly. If the ball or seat show any sign of wear or damage, replace it with a new one. This carbide ball must seal tightly against its seat for the valve to function properly.
6. When reassembling, first cover all parts with a thin coat of light oil. Tighten the valve seat securely with the 6-millimeter hexagonal wrench, then drop in the valve ball. Re-insert the spring and replace the cap, being sure the copper washer is in place and the tongue on the cap fits inside the spring. Tighten the cap securely with an adjustable wrench. Do not over-tighten.

NOTE: Wear on the ball is almost impossible to
detect visually. A sure way to test for a worn outlet valve assembly is to run the sprayer with water only for 10 to 15 minutes on high pressure in the spray setting without triggering the gun.
If the valve is defective, the end cap will get very hot to the touch. If it is functioning properly, it will stay approximately the same temperature as the water running through it.

Priming Knob Slippage
Sometimes the two allen screws holding the black plastic PRIMING KNOB outer cover will vibrate loose. This allows the knob to turn without changing the valve setting. If this happens, loosen the screw with a 1/16 allen wrench, turn the knob to spray and retighten.

OPTIONAL HOPPER ASSEMBLY
CONVERTING SPRAYER FOR HOPPER OPERATION
The hopper assembly consists of the hopper, hopper return tube and hopper screen. To make the conversion:
1. Remove suction tube and return tube and brass return tube fitting from the unit.
2. To convert the cart into its horizontal configuration as shown in Figure 49, reverse the positions of the handle and pail bracket.
3. Screw the hopper directly onto the inlet valve where the suction tube was removed. Make the connection hand tight, just tight enough to prevent paint leakage or air suction around the threads.
Hopper Return Tube
Hopper
4. Screw in the plastic return tube fitting into the paint pump port that the brass fitting was removed from. Attach hopper return tube to the fitting where the suction set return tube was removed. The connec­tion needs to be only hand tight.
5. Fit the hopper screen into the bottom of the hopper, being sure it is properly seated.
NOTE: The hopper screen is essential to trap debris and other foreign objects from entering the pump. Do not operate the sprayer without the screen properly in place.
Cleaning Hopper Unit
To clean the hopper unit:
1. Flush the pump and hose with water or solvent following the same procedure as with the suction tube, being sure the return tube is thoroughly flushed out.
Figure 49 - Optional Hopper
2. Clean the hopper screen with water or appropriate solvent. If necessary use a nylon or natural bristle brush dipped in solvent or soapy water.
3. Wash the hopper thoroughly using soapy water for latex paint, the appropriate solvent with other materials.
