SAFETY WARNINGS

HIGH PRESSURE SPRAY CAN CAUSE EXTREMELY SERIOUS INJURY.

Handle as you would a loaded firearm.

Follow the PRESSURE RELIEF PROCEDURE

.

DO NOT USE HALOGENATED SOLVENTS IN THIS SYSTEM.

The prime valve, and most airless guns have aluminum parts and may explode. Cleaning agents, coatings, paints or adhesives may contain halogenated hydrocarbon solvents. DON'T TAKE CHANCES! Consult your material suppliers to be sure. Some of the most common of these solvents are: Carbontetrachloride, Chlorobenzene, Dichloroethane, Dichloroethyl Ether,

Ethylbromide, Ethylchloride, Tethrachloethane. Alternate valves and guns are available if you need to use these solvents.

MEDICAL ALERT - Airless Spray Wounds

If any fluid appears to penetrate your skin, get

EMERGENCY MEDICAL CARE AT ONCE.

DO NOT TREAT AS A SIMPLE CUT.

Tell the doctor exactly what fluid was injected.

NOTE TO PHYSICIAN: Injection in 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 exotic coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

INJECTION HAZARD

• Fluids under high pressure from spray or leaks can

penetrate the skin and cause extremely serious injury,

including the need for amputation.

• NEVER point the spray gun at anyone or any part of

the body.

• NEVER put your hand or fingers over the spray tip. Do

not use a rag or any other materials over your fingers.

Paint will penetrate through these materials & into the hand.

• NEVER try to stop or deflect leaks with your hand or body.

• ALWAYS have the tip guard in place when spraying.

• ALWAYS lock the gun trigger when you stop spraying.

• ALWAYS remove tip from the gun to clean it.

• NEVER try to "blow back" paint, this is not an air spray

sprayer.

• ALWAYS follow the PRESSURE RELIEF PROCEDURE

before cleaning or removing the spray tip or servicing any

system equipment.

• Be sure the equipment safety devices are operating properly

before each use.

• Tighten all of the fluid connections before each use.

MEDICAL TREATMENT

\

• If any fluid appears to penetrate your skin, get EMERGENCY

CARE AT ONCE! DON'T TREAT AS A SIMPLE CUT.

• Go to an emergency room immediately.

• Tell the doctor you suspect an injection injury.

• Tell him what kind of material you were spraying with

and have him read NOTE TO PHYSICIAN above.

GENERAL PRECAUTIONS

• NEVER alter equipment in any manner.

• NEVER smoke while in spraying area.

• NEVER spray highly flammable materials.

• NEVER use around children.

• NEVER allow another person to use sprayer unless

he is thoroughly instructed on its safe use and

given this operators manual to read.

• ALWAYS wear a spray mask, gloves and protective

eye wear while spraying.

• ALWAYS ensure fire extinquishing equipment is

readily available and properly maintained.

NEVER LEAVE SPRAYER UNATTENDED

WITH PRESSURE IN THE SYSTEM.

FOLLOW PRESSURE RELIEF

PROCEDURES.

NOTE: United States Government safety standards have been adopted under the

SAFETY WARNINGS

ALWAYS INSPECT SPRAYING AREA

• Keep the spraying area free from obstructions.

• Make sure the spraying area has good ventilation

to safely remove vapors and mists.

• NEVER keep flammable material in spraying area.

• NEVER spray in vicinity of open flame or other

sources of ignition.

• The spraying area must be at least 20 ft. away from

spray unit.

SPRAY GUN SAFETY

• ALWAYS set gun safety lock in the "LOCKED"

position when not in use & before servicing or cleaning.

• NEVER remove or modify any part of the gun.

• ALWAYS REMOVE THE SPRAY TIP when cleaning.

Flush unit at the LOWEST POSSIBLE PRESSURE.

• ALWAYS check operation of all gun safety devices

before each use.

• Be very careful when removing the spray tip or hose

from the gun. A plugged line will contain fluid under

pressure. If the tip or line is plugged, follow the

PRESSURE RELIEF PROCEDURE.

TIP GUARD

• ALWAYS have the tip guard in place on the spray

gun while spraying. The tip guard alerts you to the

injection hazard and helps prevent accidentally

placing your fingers or any part of your body close

to the spray tip.

SPRAY TIP SAFETY

• Use extreme caution when cleaning or changing

spray tips. If the spray tip clogs while spraying, en-

gage the gun safety latch immediately. ALWAYS

follow the PRESSURE RELIEF PROCEDURE

and then remove the spray tip to clean it.

• NEVER wipe off build up around the spray tip.

TOXIC FLUID HAZARD

• ALWAYS remove tip guard & tip to clean AFTER

pump is turned off and the pressure is relieved by

following the PRESSURE RELIEF PROCEDURE.

• Hazardous fluid or toxic fumes can cause serious injury

or death if splashed in eyes or on skin, inhaled or

swallowed. Know the hazards of the fluid you are using.

Store & dispose of hazardous fluid according to

manufacturer, local, state & national guidelines.

• ALWAYS wear protective eyewear, gloves,

clothing and respirator as recommended by fluid

manufacturer.

HOSES

• Tighten all of the fluid connections securely before each

use. High pressure fluid can dislodge a loose coupling or

allow high pressure spray to be emitted from the coupling

and result in an injection injury or serious bodily injury.

• Only use hoses with a spring guard. The spring guard

helps protect the hose from kinks or other damage which

could result in hose rupture and cause an injection injury.

• NEVER use a damaged hose, which can result in hose

failure or rupture and cause an injection injury or other

serious bodily injury or property damage. Before each use,

check entire hose for cuts, leaks, abrasions, bulging of the

cover, or damage or movement of couplings. If any of

these conditions exist, replace the hose immediately.

• NEVER use tape or any device to try to mend the hose as

it cannot contain the high pressure fluid. NEVER

ATTEMPT TO RECOUPLE THE HOSE. A high pressure

hose is not recoupleable.

GROUNDING

• Ground the sprayer & other components in the system to

reduce the risk of static sparking, fire or explosion which

can result in serious bodily injury and property damage.

For detailed instructions on how to ground, check your

local electrical code.

• ALWAYS ensure switch is in OFF position before

plugging unit in.

Always Ground All of These Components:

1. Sprayer: plug the power supply cord, or extension cord,

each equipped with an undamaged three-prong plug, into a

properly grounded outlet. DO NOT USE AN ADAPTER.

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. (Note: The table on the top of the next page shows

the correct size to use depending on cord length and name

plate ampere rating. If in doubt, use the next heavier gauge.

The smaller the gauge number, the heavier the cord.)

2. Fluid hose: use only grounded hoses.

3. Spray gun or dispensing valve: grounding is obtained

through connection to a properly grounded fluid hose and

pump.

4. Object being sprayed: according to your local code.

5. All solvent pails used when flushing.

• Once each week, check electrical resistance of hose (when

using multiple hose assemblies, check overall resistance.)

Overall (end to end) resistance of unpressurized hose must

not exceed 29 megohms (max.) for any coupled length or

combination of hose lengths. If hose exceeds these limits,

replace it immediately.

• Never exceed 500 ft. (150 m) overall combined cord

length to assure electrical continuity.

Always Follow Recommended Pressure and Operating Instructions

• ALWAYS use approved high pressure fittings and

replacement parts.

• ALWAYS ensure fire extinquishing equipment is readily

available and properly maintained.

KEEP CLEAR OF MOVING PARTS

Keep clear of moving parts when starting or operating the sprayer. Do not put your fingers into any openings to avoid amputation by moving parts or burns on hot parts. Precaution is the best insurance against an accident. When starting the motor, maintain a safe distance from moving parts of the equipment. Before adjusting or servicing any mechanical part of the sprayer, follow the PRESSURE RELIEF PROCEDURE.

AVOID COMPONENT RUPTURE

• This sprayer operates at 3000 psi (205 bar). Always be

sure that all components and accessories have a maximum

working pressure of at least 3000 psi to avoid rupture

which can result in serious bodily injury including

injection and property damage.

• NEVER leave a pressurized sprayer unattended to avoid

accidental operation of it, which could result in serious

bodily injury.

• ALWAYS follow the PRESSURE RELIEF PROCEDURE

whenever you stop spraying and before adjusting,

removing or repairing any part of the sprayer.

• NEVER alter or modify any part of the equipment to

avoid possible component rupture which could result in

serious bodily injury and property damage.

• NEVER use weak, damaged, or non-conductive paint

hose. Do not allow kinking or crushing of hoses or

allow it to vibrate against rough, sharp or hot surfaces.

Before each use, check your hoses for damage and wear

and ensure all of the fluid connections are secure.

• ALWAYS replace any damaged hose. NEVER use tape

or any device to mend the hose.

• NEVER attempt to stop any leakage in the line or

fittings with your hand or any part of the body. Turn off

the unit and release pressure by following PRESSURE

RELIEF PROCEDURE.

PREVENT STATIC SPARKING FIRE/EXPLOSIONS

• ALWAYS be sure all of the equipment & objects being

sprayed are properly grounded. Always ground sprayer,

paint bucket and object being sprayed. See the grounding

section of this manual for grounding information.

• Vapors created when spraying can be ignited by sparks.

To reduce the risk of fire, always locate the sprayer at

least 20 feet (6 m.) away from spray area. Do not plug in

or unplug any electrical cords in the spray area. Doing so

can cause sparks which can ignite any vapors still in the

air. Follow the coating & solvent manufacturers safety

warnings and precautions.

• Use only conductive fluid hoses for airless applications.

Be sure the gun is grounded through the hose connections.

Check ground continuity in hose & equipment. Overall

(end to end) resistance of unpressurized hose must not

exceed 29 megohms for any coupled length or combination

of hose length. Use only high pressure airless hoses with

static wire approved for 3000 psi.

FLUSHING

• Reduce the risk of injection injury, static sparking or

splashing by following the specific cleaning process.

• ALWAYS follow the PRESSURE RELIEF PROCEDURE.

• ALWAYS remove the spray tip before flushing. Hold

the metal part of the gun firmly to the side of a metal pail

& use the lowest possible fluid pressure during flushing.

• NEVER use cleaning solvents with flash points below

140 degrees F. Some of these are: acetone, benzene,

ether, gasoline, naptha. Consult your supplier to be sure.

• NEVER SMOKE in the spraying/cleaning area.

WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS AND THINNERS

1. When spraying with flammable liquids, the unit must be located a minimum of 25 feet away from the spraying area in a

well ventilated area. Ventilation must be sufficient enough to prevent the accumulation of vapors.

2. To eliminate electrostatic discharge, ground the spray unit, paint bucket & spraying object. See GROUNDING. Use only

high pressure airless hoses approved for 3000 psi which is conductive.

3. Remove the spray tip before flushing. Hold the metal part of the gun firmly to the side of a metal pail & use the lowest

possible fluid pressure during flushing.

4. Never use high pressure in the cleaning process. USE MINIMUM PRESSURE.

5. Do not smoke in spraying/cleaning area.

STARTING UP

4. Adjusting the pressure

a. Turn the Pressure Control Knob Clockwise to

increase pressure and counterclockwise to decrease

pressure.

b. Always use the lowest pressure necessary to

completely atomize the material.

Note: Operating the sprayer at higher pressure than needed, wastes material, causes early tip wear, and shortens sprayer life.

c. If more coverage is needed, use a larger tip rather

than increasing the pressure.

d. Check the spray pattern. The tip size and angle

determines the pattern width and flow rate.

Avoiding Tip Clogs

There is an easy way to keep the outside of the tip clean from material build up:

Every time you stop spraying, for even a minute, lock the gun and submerge it into a small bucket of thinner suitable for the material sprayed.

Thinner will dissolve the buildup of paint on the outside of tip, tip guard and gun much more effectively if the paint doesn't have time to dry out completely.

WARNING

Follow the "Pressure Relief Procedure".

To reduce the risk of injection, never hold your hand, body, fingers or hand in a rag in front of the spray tip when cleaning or checking for a cleared tip.

Always point the gun toward the ground or into a waste container when checking to see if the tip is cleared or when using a self-cleaning tip.

WARNING

When you spray into the paint bucket, always use the lowest spray pressure and maintain firm metal to metal contact between gun and container.

WARNING

Be sure to relieve pressure in the pump after filling with Airlessco Pump Conditioner.

5. When Shutting off the Sprayer

a. Whenever you stop spraying, even for a short break,

follow the "Pressure Relief Procedure".

b. Clean the tip & gun as recommended on page 15 for

Airlessco 007 gun or separate gun instruction manual for

all others.

c. Flush the sprayer at the end of each work day, if the

material you are spraying is water-based, or if it could

harden in the sprayer overnight. See "Flushing". Use a

compatible solvent to flush, then fill the pump and hoses

with an oil based solvent such as mineral spirits.

d. For long term shutdown or storage, refer to the

"Flushing" section of this manual.

To stop the unit in an emergency, turn the motor off. Then relieve the fluid pressure in the pump and hose as instructed in the

Pressure Relief Procedure.

PRESSURE RELIEF PROCEDURE

IMPORTANT!

To avoid possible serious body injury, always follow this procedure whenever the sprayer is shut off, when checking it, when installing, changing or cleaning tips, whenever you stop spraying, or when you are instructed to relieve the pressure.

1. Engage the gun safety latch. Refer to the separate

instruction manual provided with your gun on its

safety features and how to engage safety latch.

2. Turn the unit off & unplug it from the electrical outlet.

3. Disengage the gun safety latch and trigger the gun

to relieve residual fluid pressure.

Hold metal part of the gun in

contact with grounded metal pail.

USE MINIMUM PRESSURE !

4. Turn Prime/Pressure Relief Valve (PR Valve) to the open

(priming) position to relieve residual fluid pressure.

There will be a wider gap between valve handle and cam

body when in open position. In the closed position there is only a very slight gap.

.

Note: The valve handle can move both clockwise and counter clockwise and can face different directions.

5. Re-engage gun safety latch and

close Prime/Pressure Relief Valve.

If the SPRAY TIP OR HOSE IS CLOGGED, follow Step 1 through 5 above. Expect paint splashing into the bucket while relieving pressure during Step 4.

If you suspect that pressure hasn't been relieved due to damaged Prime/Pressure Relief Valve or other reason, engage the gun safety latch and take your unit to an authorized Airlessco

Service Center.

DAILY MAINTENANCE

1. Keep the displacement pump packing nut/wet cup lubricated with Airlessco TSO (Throat Seal Oil) at all times. The

TSO helps protect the rod and the packings.

2. Inspect the packing nut daily. Your pump has a patented Triple Life Packing System. Packing life will be extended a

minimum of three times if the following "Packing Adjustment" procedure is followed:

If seepage of paint into the packing nut and/or movement of the piston upward is found

(while not spraying), the packing nut should be tightened enough to stop leakage only, but not any tighter. Overtightening will damage the packings and reduce the packing life.

Use larger spray angle tip. (If coverage is OK, try tip in same nozzle group)

Use next smaller tip

Reduce pressure

Use next larger tip

Change for new tip

Use tip with a smaller spray angle

Thin material

Reduce pressure and/or use smaller tip

Thin material

Clean carefully

Replace with new tip

Use 1-3% "short" solvents remainder "long" solvents.

(This is most likely to happen with material of low viscosity, lacquers etc.)

Clean surface to be sprayed

Clean screen

Use coarse screen if orifice size allows

Use coarser screen, larger orifice tips. Obain ball milled paint. If thinner was added, test to see if a drop on top of paint mixes or flattens out on the on the surface. If not, try different thinner in fresh batch of paint.

SPRAY TIP SELECTION

Spray tip selection is based on paint viscosity, paint type, and job needs. For light viscosities (thin paints), use a smaller tip; for heavier viscosities (thicker paints), use a larger tip size.

Spray tip size is based on how many gallons of paint per minute can be sprayed through the tip. Do not use a tip larger than the maximum pump flow rate or capacity the sprayer can accommodate. Pump flow rate is measured in gallons per minute (GPM).

Protected By U.S. Patent No. 6,264,115 Other U.S. & Foreign Patents Applied For.

PATTERN WIDTH

Thickness of the paint coat per stroke is determined by spray tip "fan width", rate of the spray gun movement, and distance to surface.

SPRAY TIP SELECTION

Two tips having the same tip size, but different pattern widths will deliver the same amount of paint over a different area

(wider or narrower strip). A spray tip with a narrow pattern width makes it easy to spray in tight places.

SPRAY TIP REPLACEMENT

During use, especially with latex paint, high pressure will cause the orifice to grow larger. This destroys the pattern.

Replace tips before they become excessively worn. Worn tips waste paint, cause overspray, make cutting-in difficult, and decreases sprayer performance.

ELECTRIC MOTOR MAINTENANCE

1. LUBRICATION - This motor is supplied with prelubricated ball bearings, lubricated for life of bearing.

2. MOTOR BRUSHES - These need periodic inspection and replacement as wear indicates. Brush wear is greatly influenced by individual application. It is recommended that brush wear be checked at early intervals of operation in order to determine future required inspections. Standard Leeson brushes for this motor have an initial length of 3/4".

When the brushes are worn to a length of 3/8", they should be replaced.

3. TO CHANGE THE BRUSHES, follow the procedures below:

a. Unplug the machine.

b. Open the two covers at the rear of the motor.

c. Loosen the screw holding the brush terminal and remove the brush lead.

d. Push the brush retainer clip in and remove.

e. Remove the worn brushes (one on each side of motor).

f. Install new brushes in reverse order and replace covers.

NOTE: For longer life, new brushes (Part No. 331-131) need to have a run in period. After changing brushes, set up the machine for spraying. Use a bucket of water and Airlessco Pump Conditioner mixture, a 50 foot x 1/4" airless hose, airless gun with 0.017 tip on unit, turn the Prime/PR Control Valve to the

Prime position and turn the unit on. Turn the Pressure Control Knob to maximum pressure (fully CW position) and let the pump cycle at high speed in the prime position for 20 minutes. This will allow the brushes to "run in" properly giving a longer life.

ELECTRICAL BOARD CALIBRATION (4 Series)

Note: Anytime a sensor, pressure control assembly (board) or both are replaced, the following calibrations must be performed.

1. PRESSURE CALIBRATION

1. Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a 5000 psi glycerin filled pressure gauge to

the pump.

2. Place the suction tube into a bucket of Airlessco Pump Conditioner and water.

3. Turn prime/pressure relief valve to the prime (open) position.

4. Turn pressure control knob clockwise until machine starts to prime.

5. Place the prime/pressure relief valve in the pressure (closed) position.

6. While watching pressure gauge, slowly adjust the Pressure Trimpot (Fig. 21) (clockwise to increase and

counterclockwise to decrease) until the maximum static pressure is 3000 psi, with the pressure control

knob fully clockwise. Trigger the gun several times to ensure pressure returns to 3000 psi .

2. PHASE LIMIT TRIMPOT CALIBRATION

1. Attach a 50', 1/4" airless hose, airless gun with .017 tip and a 5000 psi glycerin filled pressure gauge to the

pump.

2. Place the suction tube into a bucket of Airlessco Pump Conditioner and water.

3. Turn pump ON and turn up pressure control until the machine starts to prime.


5. Pressurize pump to 600 psi.

6. Trigger the gun several times noting the deadband (the amount of pressure drop before the pump rebuilds to

set pressure).

7. If deadband is greater than 100 psi, adjust the phase limit (Figure 21) trimpot so that the deadband is less than

100 psi and the pressure increase after the gun trigger is released is less than 200 psi. These pressures are

guidelines and may vary slightly from pump to pump.

STEPS (SEE FIGURE 22)

STEP 1: After making sure that the machine is plugged into the wall, verify that the on-off switch is in the ON position and that the pressure control knob is turned all the way to the right (clockwise for maximum pressure).

STEP 2: Using your multi-meter, test the fuse for continuity or replace with a new fuse. If the fuse reads good, move on to step three.

STEP 3: Using a Phillips Head screwdriver, remove the four screws holding the pressure control assembly. Locate the light on the board indicating that there is power

(it will be red or green). If the light is OFF proceed to step four. If the light is ON go

STEP 4: Locate the L1 and L2 terminals on the board, and then using your multi-meter check to make sure you have 110 volts AC across the two terminals (the cord wires will still be attached). If there is no voltage at these leads, there is no power getting to the machine. Check your power source (outlet, circuit breaker, extension cord, and power cord). If you have AC voltage at the L1 and L2 terminals, go to step 5.

STEP 5: Disconnect the two red motor leads (S1 & S2) and test for continuity between them. No continuity means that the thermal coupler has opened due to excessive motor heat. If the motor is still hot to the touch, allow it to cool and then retest. If the motor is cool and there is not continuity on the red leads, contact your local Leeson repair facility to repair/replace the thermal coupler. Continuity shows that the motor's thermal coupler has not tripped. Proceed to step six.

STEP 6: If everything checks out in steps one through five and the power indicating light is still out, replace the pressure control assembly.

STEP 7: Remove the motor brush covers and turn the machine on. Set the potentiometer (POT) at maximum pressure and check for DC voltage across both brush terminals.

You should read greater than 80 volts DC. IF YOU DO NOT HAVE DC VOLTAGE

GO TO STEP EIGHT. If you have DC voltage, turn the machine off and unplug it from the wall. Check to make sure that the brushes are making good contact with the armature. Replace the brushes if they are less than 3/8" long. If the brushes are good, replace the motor.

STEP 8: Plug another sensor into the board and perform the zero calibration procedure. If the machine starts to run, the sensor was bad. If there is no replacement sensor available, use a multi-meter to test the resistance across the red and black wires of the sensor (be sure to test at the plug). You should read 1.5 - 3.5k ohms. A faulty sensor usually reads no continuity (open). If the sensor passes all the tests move to step nine.

STEP 9: Plug another potentiometer (POT) into the control board. If the machine starts, the old POT as bad. When replacement POT is not available, remove the POT lead (with the machine turned off) from the control board and test the resistance between the red and black wires (be sure to test at the plug). The resistance should read between 8-12k ohms if it is outside of this range replace the POT.

STEP 10: If you have DC voltage at the motor brushes and all of the components check out fine in steps eight and nine, replace the pressure control assembly.

ELECTRICAL BOARD CALIBRATION (5/6 Series)

Note: Anytime a sensor, pressure control assembly (board) or both are replaced, the following calibrations must be performed.

1. ZERO CALIBRATION

1. Place prime/pressure relief valve in the prime (open) position.

2. Set the pressure control knob to the minimum setting (CCW).

3. Remove the screws and lower the pressure control assembly.

4. Ensure the jumper is on the "P-ZR" terminal. Note: This jumper comes with a new pressure control assembly

(board) and is installed on the "P-ZR" terminals. If you are "Zero Calibrating" a pressure control assembly

presently in the unit, remove jumper from single terminal P-ZR and place on both terminals P-ZR. When Zero

Calibration is complete, replace jumper on a single terminal of P-ZR.

5. Turn machine "ON" and ensure it is not cycling.

6. If the yellow zero light on the electrical board is ON, use an insulated screwdriver to turn the "ZERO" trimpot

counter-clockwise until the light goes out. Then turn it clockwise until the light just comes back on. If so

equipped, look at the LCD Display and if "0000" is showing the Zero Calibration is complete. If the display

shows more than "0000", turn the Zero Trimpot CCW until "0000" is showing. If "-- -- --" is showing, turn the

zero trimpot CW until "0000" is displayed.

7. If the yellow light is OFF, turn the "Zero" trimpot clockwise, just until the light comes on and stop. Confirm

"0000" is displayed.

NOTE: If the yellow light remains constantly "ON", or "OFF" during this calibration, the sensor

is defective and should be replaced.

8. IMPORTANT:When calibration is complete, move jumper from both "PZ-R" terminals to single terminal

on P-ZR.

2. PRESSURE CALIBRATION

1. Complete the ZERO calibration, as per "ZERO CALIBRATION" prior to commencing this calibration.

2. Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a 5000 psi glycerin filled pressure gauge to the pump.

3. Place the suction tube into a bucket of Coro-chek and water.

4. Turn prime/pressure relief valve to the prime (open) position.

5. Turn pressure control knob clockwise until machine starts to prime.


7. While watching pressure gauge, slowly adjust the pressure trimpot (clockwise to increase and counterclockwise

to decrease) until the maximum static pressure is 3000 psi, with the pressure control knob fully clockwise.

Trigger the gun several times to ensure pressure returns to 3000 psi.

3. LIQUID CRYSTAL DISPLAY (LCD) CALIBRATION

( If so equipped)

1. Complete the "ZERO CALIBRATION" and "PRESSURE CALIBRATION" procedures prior to commencing

this calibration.

2. Turn pressure control knob up until system pressure is above 2500 psi (as indicated on glycerin filled pressure

gauge) and the machine is not cycling.

3. Use an insulated screwdriver to adjust the Set trimpot. Turn trimpot CCW until it clicks, then adjust to match

pressure against pressure gauge reading.

4. Move the pressure control knob to different settings and trigger the gun several times to ensure that the LCD

continues to match the pressure gauge reading.

29

28

ELECTRICAL BOARD CALIBRATION

(CONTINUED)

4. PHASE LIMIT TRIMPOT CALIBRATION

Formerly known as the Low Voltage or Master Voltage Calibration

1. Attach a 50', 1/4" airless hose, airless gun with .017 tip and a 5000 psi glycerin filled pressure gauge to the

pump.

2. Place the suction tube into a bucket of Pump Conditioner and water.

3. Turn pump ON and turn up pressure control until the machine starts to prime.


5. Pressurize pump to 600 psi.

6. Trigger the gun several times noting the deadband (the amount of pressure drop before the pump rebuilds to

set pressure).

7. If deadband is greater than 100 psi, adjust the low pressure voltage trimpot so that the deadband is less than

100 psi and the pressure increase after the gun trigger is released is less than 200 psi. These pressures are

guidelines and may vary slightly from pump to pump.

8. Reattach Pressure Control Assembly being careful not to pinch wires.

Note: The 331-315-99 pressure control assembly has a reddish brown terminal labelled

"Inhibit Switch". At all times there should be a jumper on the two left terminals,

which are the closest to the "S2" connection. Also on the Revision E is a terminal labelled "ON-SL". This terminal should never have a jumper on it.
