5. 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

CAUTION - Operating the sprayer at higher pres sure than need ed wastes ma te ri al, caus es early tip wear and short ens spray er 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 fl ow rate.

6. Reducing Clutch Wear

a. The fi rst 50 feet of airless spray hose should be 3/8",

the larger diameter works as a pulsation damp er and

saves unnecessary cycling of the clutch. A minimum

of 100 feet of hose should be used.

b. Adjust the Engine Speed and Pump Pressure.

First set the throttle lever to the maximum RPM

setting (fully left). Trigger the gun onto a test paper

to check the spray pattern and atomization. Ad just

the Pressure Control Knob until you get a good

pattern. Reduce RPM of engine to support pressure

without laboring engines.

7. Cleaning a Clogged Tip

IMPORTANT WARNING

Always follow the Pressure Relief Procedure on page 8 before perfoming any service or main te nance pro ce dure.

WARNING: Never hold your body, fin gers, or hand in a rag in front of the spray tip when clean ing or checking it for a cleared tip. Always point the gun toward the front or into a waste con tain er when checking to see if the tip is cleared or when using a self-cleaning tip.

a. Follow the Pressure Relief Procedure on page 8.

b. Clean the front of the tip frequently (with toothbrush

only) during the day to keep material from building up

and clogging the tip.

c. To clean and clear a tip if it clogs, refer to the separate

instruction manual re ceived with your gun and nozzle.

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 the gun into a small bucket of thinner comparable with the material sprayed. Thinner will dissolve the build up of paint on the outside of tip, tip guard and gun much more effectively than if the paint dries out completely.

WARNING: Clogged standard fl at tip - clean only af ter the tip is removed from the gun. Follow the

8. When Shutting Off the Sprayer

a. Whenever stop spraying, even for a short break, fol-

low the Pressure Relief Procedure Warning on page6.

b. Clean the tip and gun as recommended by your

separate gun instruction manual.

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

material you are spraying is waterbased, or if it could

harden in the sprayer overnight. See "Flush ing" page

1 and 2. Use a compatible solvent to fl ush, then fi ll

the pump and hoses with an oil based sovent such as

mineral spir its.

d. For long term shutdown or storage, refer to page 1.

WARNING - Be sure to relieve pres sure in the pump af ter fi lling with min er al spir its.

NOTE TO PHYSICIAN:

Injection in the skin is a traumatic injury. It is important to treat the injury sur gi cal ly as soon as possible. DO NOT DE LAY treat ment to research toxicity. Toxicity is a concern with some exotic coatings injected di rect ly into the blood stream. Consultation with a plastic surgeon or re con struc tive hand sur geon may be advisable.

WARNINGS

WARNINGS - Continued

PRESSURE RELIEF PROCEDURE

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

1. Engage gun safety latch. Refer to separate instruction manual provided with your gun on its safety features and how to en gage safe ty latch.

2. Turn engine off.

4. Re-engage gun

safety latch

3. Disengage safety latch & trigger gun to relieve residual fl uid pressure. Hold metal part of the gun in contact with grounded metal pail.

5. Turn Prime/Pressure Relief Valve as shown open (priming) to relieve fl uid pressure.

OPEN

Leave prime valve OPEN until you are ready to spray again.

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 5. If you suspect that pressure hasn't been relieved due to dam aged prime/pressure relief valve or other reason, engage gun safety latch and take your sprayer to an au tho rized Airlessco Service Center for service.

Always follow recommended pressure & operating instructions:

HOSES

Tighten all fl uid connections securely before each use.

High pressure fl uid 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.

Use only hose that has 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 in injection injury or other se ri ous bodily injury or bodily damage. Before each use, check entire hose for cuts, leaks, abrasion or bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace the hose immediately.

Nev er use tape or any device to try to mend the hose as it cannot con tain the high pressure fl uid. NEVER AT-

TEMPT TO RECOUPLE THE HOSE. High pressure hose is not recoupleable.

Help prevent damage to the hose by handling and routing carefully. Do not move the sprayer by pulling it with the hose.

8

LABELING

Keep all labels on the unit clean and readable. Re place ment labels are available from manufacturer.

GROUNDING

Ground the sprayer and other components in the sys tem to reduce the risk of static sparking, fi re or explosion which can result in serious bodily injury and property damage.

Always ground all of these components:

1. Sprayer: Connect a ground wire and clamp (supplied) to a true earth ground.

2. Fluid Hose: use only grounded hoses.

3. Spray gun or dispensing valve: grounding is obtained through connection to a properly grounded fl uid hose and pump.

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

5. All solvent pails used when fl ushing should only be metal pails which are conductive.

Once each week, check electrical resistance of hose

(when using multiple hose assemblies, check overall re sis tance of unpressurized hose must not exceed 29 me go hms (max) for any coupled length or combination of hose lengths. If hose exceeds these limits, replace it im me di ate ly.

Never exceed 500 Ft. (150 m.) overall combined hose length to assure electrical continuity.

NOTE: WARNINGS CONTINUE ON NEXT PAGE.

WARNINGS - Continued

AVOID COMPONENT RUPTURE

This sprayer operates at 3000 psi (205 bar). Al ways be sure that all com po nents and accessories have a max i mum work ing pres sure of at least 3000 psi to avoid rup ture which can result in serious bodily injury including in jec tion and prop er ty damage.

NEVER leave a pressurized sprayer unattended to avoid ac ci den tal operation of it which could result in serious bodily in ju ry.

ALWAYS follow the PRESSURE RELIEF PROCEDURE whenever you stop spraying and before adjusting, re-

mov ing 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 bodi ly injury and property damage.

NEVER use weak or damaged or non-conductive paint hose. Do not allow kinking or crushing of hoses or allow it to vibrate against rough or sharp or hot surfaces. Before each use, check hoses for damage and wear and ensure all fl uid connections are secure.

REPLACE any damaged hose. NEVER use tape or any device to mend the hose.

NEVER attempt to stop any leakage in the line or fi ttings with your hand or any part of the body. Turn off the unit and release pressure by following PRESSURE RELIEF

PROCEDURE.

ALWAYS use approved high pressure fi ttings and re-

place ment parts.

ALWAYS ensure fi re extinquishing equipment is readily avail able and properly maintained.

WARNING

Do not use halogenated solvents in this sys tem.

The prime valve, 2 gun manifold and most air less guns have aluminum parts and may ex plode.

Clean ing agents, coat ings, paints or ad he sives may con tain halogenated hy dro car bon sol vents.

DON"T TAKE CHANCES! Con sult your ma te ri al suppliers to be sure. Some of the most com mon of these sol vents are: Carbontetrachloride, Chlo-

roben zene, Dichloroethane, Dichloroethyl Ether,

Ethylbromide, Ethylchloride, Tethrachloethane.

Al ter nate valves and guns are available if you need to use these solvents.

PREVENT STATIC SPARKED FIRE/ EXPLOSIONS

ALWAYS be sure all equipment and objects being sprayed are properly grounded. Always ground sprayer, paint buck et and object being sprayed. See "grounding" on page 8 for detailed grounding information.

Vapors created when spraying can be ignited by sparks.

To reduce the risk of fi re, always locate the sprayer at least

20 feet (6 m.) away from the spray area. Do not plug in or unplug any electrical cords in the spray area, which can create sparks, when there is any chance of igniting vapors still in the air. Follow the coating & solvent man u fac tur ers safety warnings and pre cau tions.

Use only conductive fl uid hoses for airless applications. Be sure gun is grounded through hose connections. Check ground continuity in hose & equipment. Overall (end to end) re sis tance 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 splash ing by following the specifi c cleaning procedure on page 4 and 9.

ALWAYS follow the PRESSURE RELIEF PROCEDURE on page 8.

ALWAYS remove the spray tip before fl ush ing. Hold a met al part of the gun fi rmly to the side of a metal pail and use the lowest possible fl uid pressure dur ing fl ushing.

NEVER use cleaning solvents with fl ash points below 140 degress F. Some of these are: acetone, benzene, ether, gas o line, naphtha. Consult your supplier to be sure.

GAS ENGINE PRECAUTIONS

Locate unit 25 feet away from spray area in well ventilated area. NEVER operate in closed building unless exhaust is piped outside. NEVER allow hose to lay against engine mufflers or hot parts. NEVER refill fuel tank while engine is hot or is running.

Important: United States Government safety stan dards have been adopted under the Oc cu pa tion al Safety &

Health Act. These stan dards, par tic u lar ly the Gen er al

Standards, Part 1910, & the Con struc tion Stan dards, part 1926 should be con sult ed.

WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR THINNERS:

1. When spraying with fl ammable liquids, the unit must be located a minimum of 25 feet away from the spraying

area in a well ventilated area. Ventilation must be suffi cient enough to prevent the accumulation of vapors.

2. To eliminate electrostatic discharge, ground the spray unit, paint bucket and spraying object. Use only high

pressure airless hoses approved for 3000 psi which is conductive.

3. Remove spray tip before cleaning gun and hose. Make contact of gun with bucket and spray without the tip in

a well ventilated area, into the grounded steel bucket.

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

5. Do not smoke in spraying/cleaning area.

SPRAY TECHNIQUE

Good Spray Gun Technique is at the core of any spray paint operation. Operator skill and effi ciency is as important as good equipment and good paint. Good spray technique is a skill that can be quickly learned by following these sim ple instructions.

If you are not familiar with spraying tech niques, we recommend that you study this section of your man u al and prac tice the proper technique on pieces of card board or a suitable surface.

RIGHT WRONG

Hold the spray gun 12 - 15 inches away from the work surface and keep it perpendicular (straight) to the surface. Move the spray gun parallel to the work and at a right angle to the surface.

10

KEEP EVEN DISTANCE TO SURFACE

WRONG

Move the gun at a steady rate in order to apply a good coverage. The wet coat should be just under the thickness at which a run or sag will occur. slow gun movement or gun held too close will result in an overly wet or thick wet or thick coat coverage that is likely to run or sag.

Do not wave the spray gun. This waving is called arching. Instead, hold the spray gun at a 12 to 15 inch distance perpendicular from the work.

The closer the spray gun is held to the work, the thick er the paint is deposited and the faster the gun must be moved to prevent sags and runs. Hold ing the gun too far from the work will cause ex ces sive fog, overspray, and a thin and grainy coat.

SPRAY TECHNIQUE - Continued

TOTAL SPRAYGUN MOVEMENT - arm movement - full sweep

TRIGGER

POINT

TRIGGER POINT

The Actual Paint Stroke

The Actual Paint Stroke

It is important to "trigger" the gun after gun move ment

(arm movement) has started and release trig ger (shut gun off) before gun movement ends. Gun move ment is always longer than actual paint (spray) stroke. In that manner, even blend ing and uniform paint coat thickness is achieved over the entire sur face. When the gun is in mo tion as the trigger is pulled, it de pos its an even amount of paint.

FOR EVEN PAINT COAT OVERLAP HALF

THE WIDTH OF EACH PAINT STROKE.

Overlap the previous pass by half the width of the spray pattern. Aim at the bottom of the pre vi ous pass.

Spray with uniform strokes from left to right and from right to left, holding stroke speed, dis tance, lapping, and triggering as uniform as pos si ble.

TAILING GOOD PATTERN FOG, OVERSPRAY

Adjust pressure control knob so that paint is com plete ly at om ized from the spray gun. In suf fi cient pressure will result in "tail ing".

POOR PATTERN GOOD PATTERN

Too much pressure will result in excess fog and overspray, excessive tip wear, and increased sprayer wear and tear.

Always use the lowest pressure possible to obtain desirable results.

Test the spray pattern on a piece of cardboard or oth er surface.

INSIDE CORNER OUTSIDE CORNER

"Inside" and "outside" corners can be sprayed.

Aim the spray gun toward the center of the cor ner. The spray pattern is divided in half, and the edges of the spray pattern on both walls are the same.

SIZE SELECTION CHART

Spray tip selection is based on paint viscosity, paint type, your pumps output capabilities, and job needs.

For light viscosities (thin paints), use a smaller tip; for heavier vis cos i ties (thicker paints), use a larger tip size.

Going to larger spray tip sizes is dependent on how many gallons of paint per minute can be sprayed by your pump

Do not use a tip larger than the max i mum pump fl ow rate or capacity the spray er can ac com mo date. Pump fl ow rate is mea sured in gallons per min. (GPM), or where appropriate, liters per min. (LPM).

PATTERN WIDTH

Thickness of the paint coat per stroke is de ter mined by spray tip "fan width", rate of the spray gun move ment, and the distance to the surface being sprayed. Airlessco "Wide

Pattern" spray tips offer fan patterns up to 18-24" wide for optimum coverage speed. Due to the fi ne atomization at the edge of the spray pattern on Wide Pattern tips, they may not be the best choice for exterior use when wind is present.

SPRAY TIP SELECTION

Two tips having the same tip size, but different pat tern widths will deliver the same amount of paint over a dif fer ent 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 which is very abrasive, high pres sure will cause the orifi ce to grow larg er.

This de stroys the spray pat tern. Replace tips before they become excessively worn.

Worn tips waste paint, cause overspray, make cut ting-in dif fi cult. They can effect sprayer performance too because the volume of paint going thru a "blown out" tip can be greater than the pumps maximum output capacity.

13

REGULAR MAINTENANCE

1. Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod, dam ag ing the packings.

2. Keep the displacement pump packing nut/wet cup 1/3 full of

Airlessco Throat Seal Oil at all times. The TSO helps protect the packings and rod.

3. Lubricate Connecting Rod Pin every 3 months.

4. Inspect the packing nut daily. Your paint pump has

Airlessco's patented "Triple Life Packing System".

Packing life will be extended a minimum of

3 times if the proper packing tightening

pro ce dure is followed!

Packing Tightening Procedure:

Inspect the packing nut daily!

If seepage of paint into the packing nut and/ or move ment 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 to the life of other piston pumps.

FLUID PUMP DISCONNECT

1. Flush out the material you are spraying, if possible.

2. Follow the Pressure Relief Procedure on Page 6. Stop the pump in the middle of down stroke.

3. Remove the suction tube and fl uid hose (if so equipped) from the fl uid pump. On the LO-BOY, detach the hose from the front of the fl uid pump. (Fig. 20, item 14)

4. Remove 2 retaining rings and slip the sleeve of the coupling down and remove both coupling halfs. This will dis con nect fl uid pump from the connecting rod. (Fig. 22, Items 10, 11 & 12)

5. Unscrew the two tie rod locknuts.

6. Pull the pump down off the tie rods.

FLUID PUMP REINSTALL (FIG. 22)

1. Loosen the packing nut and extend piston rod to fully up position. Slip sleeve (189-047)

over the piston rod.

2. Make sure that spacer tubes (301-048) are in place.

3. Connect connecting rod with fluid pump by installing coupling halfs (189-046). Slide sleeve over

coupling halfs. Secure with retaining rings (189-048).

4. Secure the fl uid pump housing to the tie rods (100-328) and screw nuts with lock washers on loosely.

5. Tighten the tie rod nuts evenly to 30 ft. lb.

6. Reconnect fl uid hoses and suction tube (if so equipped).

NOTE: After all the rod locknuts are tight, the alignment of both rods should allow easy assembly and dis as sem bly of

the coupling. If thre is any binding, loosen and retighten all the rod locknuts to improve the align ment. Misalignment

causes premature wear of seal and packings.

7. Tighten the packing nut, until there is resistance, then 1 full turn tighter. Approximately 4 threads will show, when

new packings are installed. Fill the wet cup of the packing nut 1/3 full with TSO.

8. Start the pump and operate it slowly (at low engine speed and pressure setting ) to check the piston rod for

binding. Adjust tie rod lock nuts if necessary to eliminate binding.

9. Run at maximum pressure for several minutes, relieve pressure and repeat step 7.

TROUBLESHOOTING - Clutch Does Not Engage

STEP 1:

Ensure that the pressure control knob (POT) is in the maximum (CW) position.

STEP 2

: Remove the upper and lower clutch and electrical covers.

STEP 3:

Check all electrical connections between the engine magneto, sensor, control board and clutch for loose con nec tions or damaged leads. See Fig.13.

STEP 4

: Disconnect the two leads from the control board (blue) and the clutch assembly (black). Using a mul-

ti m e ter, with the engine at maximum RPM, pres sure control knob in the maximum position and the prime valve open (priming) position, test the DC voltage across the boards leads (blue). This voltage must be 13-14 VDC. If the readings are correct, the board, sensor and magneto are okay and the problem is the clutch assembly. If this is the case, proceed to Step 5. If the voltage is outside this range go to Step 7.

STEP 5:

Measure resistance between the clutch leads (black). This value must be 10-16 ohms. If this reading is out of specifi cations the clutch is defective and must be replaced, otherwise continue troubleshooting.

STEP 6:

If the clutch resistance readings of Step 5 are correct, check the spac ing between the clutch fi eld and plate. The gap should be .012” to .024”. If the gap is greater than .028 the gap is too wide. If this gap is too wide, re move the spacer (Fig. 15, Item 4) from the clutch assembly. Should the clutch still not engage, replace the clutch as sem bly. See page 19 in manual.

STEP 7:

When the DC voltage from the board is not 13-14 VDC, disconnect the control board lead (black) from the engine magneto lead (pink), located on the side of the engine. With the engine at maximum RPM, pressure control knob in maximum (CW) position and prime valve open (priming), read the AC voltage from the magneto lead to the sprayer frame. This reading should be 19-24 VAC. If outside this range, contact your local Honda repair facility for magneto re place ment. If the magneto is producing the proper AC voltage, continue to Step 8.

STEP 8:

Test the sensor by reading the resistance between the red and black wires. The resistance runs between 1.5-3 kohms. A defective sensor usually shows no resistance (open). If the reading is outside standards, replace the sensor. An alternative method to test the sensor, is to plug a new sensor into the board and see if the clutch will engage. Caution! When using this method, ensure prime/pressure valve is in the prime position. This is important because the sensor plugged into the board is not measuring pressure in the fl uid section.

STEP 9:

When Steps 7 & 8 have been completed and the magneto and sensor check good, the electrical control board is the only item left, replace the board. See page 20 in manual.
