•ALWAYS use approved high pressure fittings and replacement parts.
•ALWAYS ensure fire extinquishing equipment is readily available and properly maintained.
SAFETY WARNINGS
GROUNDING
Ground the sprayer and 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.
Alwaysground allof thesecomponents:
•Sprayer: Connect a ground wire and clamp (supplied) to a true earth ground.
•FluidHose: use only grounded hoses.
•Spraygunordispensingvalve: grounding is obtained through connection to a properly
grounded fluid hose and pump.
•Objectbeingsprayed: according to your local code.
• All solvent pails used when flushing should only be metal pails which are conductive.
Once each week, check electrical resistance of hose (when using multiple hose assemblies, check
overall 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 hose length to assure electrical continuity.
Do not use halogenated solvents in this system. The prime valve, 2 gun manifold 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.

PREVENT STATIC SPARKING FIRE/ EXPLOSIONS
ALWAYS be sure all equipment and objects being sprayed are properly grounded. Always ground sprayer, paint
bucket and object being sprayed. See "grounding" on page 4 for detailed 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 the spray area. Do not plug in or unplug any electrical cords in the spray area, this can
create sparks when there is any chance of igniting vapors still in the air. Follow the coating & solvent manufacturers
safety warnings and precautions.
Use only conductive fluid hoses for airless applications. Be sure gun is grounded through 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.
WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR PAINT
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 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.
GAS ENGINE PRECAUTIONS
Locate unit 25 feet away from spray area in well ventilated area.
• NEVER operate in closed buildings 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 standards have been adopted under the
Occupational Safety & Health Act. These standards, particularly the General Standards, Part
1910, & the Construction Standards, part 1926 should be consulted.
FLUSHING
Reduce the risk of injection injury, static sparking or splashing by following the specific cleaning procedure on page 7.
•ALWAYS follow the PRESSURE RELIEF PROCEDURE on page 11.
•ALWAYS remove the spray tip before flushing. Hold a metal part of the gun firmly to the side of a metal pail and
use the lowest possible fluid pressure during flushing.
•NEVER use cleaning solvents with flash points below 140º F. Some of these are: acetone, benzene, ether,
gasoline and naphtha. Consult your supplier to be sure.
•NEVERsmoke in the spraying/cleaning area.

STARTING UP
The control valve sets the prime or pressure position
as well as the spraying pressure. When the valve is
fully counter-clockwise the unit is in the prime position.
As the control valve is turned clockwise, the unit’s
output pressure to the gun is gradually increased until
the control valve is fully clockwise and the unit is at
2500 psi.
FOLLOW THE "PRESSURE RELIEF
PROCEDURES" ON PAGE 11 WHENEVER
YOU:
- are instructed to relieve pressure
- stop spraying
- checking or servicing any of the system equipment.
- install or clean the spray tip.
HANDLE THE SPRAY SYSTEM AS YOU
WOULDALOADED FIREARM!!
2. Prepare the Material
a. Prepare the material according to the
manufacturer's material recommendations.
b. Place the suction tube into the material
container.
4. Prime the Pump
a. Allow pump to operate until paint comes from gun.
b. Release the trigger and engage the gun safety latch.
c. Turn Control Valve to the prime position (Fully CCW)
ensuring the pressure is released from the system.
d. Install spray tip onto gun.
f. Turn Control Valve clockwise to the desired spray
pressure (max. 2500 psi).
g. Disengage the gun safety lock and you are ready to
start spraying.
To stop the unit in an emergency or before
performing any service or maintenance
procedurefollowthePressure Relief
Procedure on page 11 to relieve the
fluidpressure.
3. Starting the Sprayer
(see Fig. 6 above)
a. Control Valve must be open to the priming
position or fully counterclockwise.
b. Pressure Control Knob must be in the low
pressure position.
c. Follow the procedure under "How to Flush",
page 7, Steps 6 through 12.
5. Adjusting the Pressure
a. Turn the Control Valve clockwise to increase
pressure and counterclockwise to decrease pressure.
b. Always use the lowest pressure necessary to
completely automize the material.
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.
If you spray into the paint bucket,
always use the lowest spray pressure and
maintain firm metal to metal contact between
gun and container. See page 7, Fig. 4.
Operating the sprayer at higher
pressure than needed wastes material, causes
early tip wear and shortens sprayer life.

6. Cleaning a Clogged Tip.
Always follow the Pressure Relief Procedure
before performing any service or
maintenance procedure.
Neverholdyour body,fingers,orhandin
frontofthespray tip when cleaning or
checkingit foraclearedtip. Alwayspoint

whencheckingtosee if thetipiscleared
orwhenusing aself-cleaningtip.
a. Follow the Pressure Relief Procedure.
b. Clean the front of the tip frequently (with a tooth-
brush 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 received with your gun
and nozzle.
There is an easy way to keep the outside of
the tip clean from material build-up:
Everytime you stop spraying, for even a minute, lock
the gun and submerge the gun nozzle into a small bucket
of thinner compatible with the material sprayed.
Thinner will dissolve the build up of paint on the
outside of the tip, tip guard and gun much more
effectively than if the paint dries out completely.

FollowthePressure ReliefProcedure
7. When shutting Off the Sprayer
a. Whenever you stop spraying, even for a short break,
follow the Pressure Relief Procedure.
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 "Flushing" page 6
and 7. 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 page 6.

PRESSURE RELIEF PROCEDURE
Tighten all 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.
HOSES
2. Turn engineoff.
3. Disengage safety latch &
trigger gun to relieve residual
fluidpressure. Hold metalpart of thegun in
contactwith groundedmetal pail.
4. Re-engage gun safety latch
1. Engage gun safety latch. Refer to
separateinstructionmanual provided
with your gun on its safety features
and how to engage safety latch. 5. TurnControlValve (Prime/Pressure
Relief Valve)asshown open (priming)
torelieve fluid pressure.
To avoidpossibleseriousbodilyinjury,includinginjection, alwaysfollowthis procedure
wheneverthe sprayeris shut off,whenchecking orservicing it,wheninstalling orchanging
thetips, whenever youstopspraying or whenyou are instructedtorelieve the pressure.
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 damaged prime/pressure relief valve or
other reason, engage gun safety latch and take your sprayer to an authorized Airlessco Service Center for
service. *Always follow recommended pressure & operating instructions.
NEVER use a damaged hose which can result in hose failure or rupture and cause an injection injury
or other serious bodily injury or bodily damage. Before each use, check entire hose for cuts, leaks,
abrasions or bulging of 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 RECOUP THE HOSE. High pressure hoses are not
recoupable. Help prevent damage to the hose by handling and routing carefully. Do not move the
sprayer by pulling it with the hose.
Use only a hose that has a spring guard. The spring guard helps protect the hose from kinks or other dam-
age which could result in hose rupture and cause an injection injury.
11

c. Tighten locking nut and retest gun triggers for
proper function.
Note: There is an additional cable adjustment
where the cable attaches to the gun holder
assembly. Use only if the gun trigger
adjustment is insufficient.
5. Miscellaneous Operations
a. CURBS: Adjust gun to desired height and turn
swivel head towards curb.
b. WIDE STRIPES: Install wider fan striping tips
and raise the gun height to achieve the desired
width line. Also angle guns slightly towards each
other to get an even coat of paint.
c. STENCILS: Install standard spray tip on the
outer gun. Remove this gun from the gun holder
and spray out the stencils.
d. STANDARD PAINTING: Same as stencils, but
use additional paint hose as required.
LINE STRIPING OPERATION
1. Choose handle location
The choices are, installing the handle opposite
of the single wheel assembly (standard set up)
or placing the handle directly over the single
wheel assembly. The handle location is really a
matter of personal preference, however having
the handle away from the single wheel assembly
allows for easier loading/unloading from a van.
2. Choose the gun arm position
There are six holes in the frame for mounting
the gun arm. In a standard set up (handle away
from the single wheel assembly), the gun arm
would be mounted in one of the two mounting
holes near the single wheel. This allows for an
easier visual check for straight line striping and
for basic arc striping. The mounting holes under
the handle are usually used when the handle has
been placed over the single wheel. Experiment
with different combinations to find the set up
that you prefer.
3. Setting up the guns
a. Ensure that striping tips are in the guns.
b. Pick a tip size for the desired line width.
Example: a 217ST tip for a four inch line.
c. Place gun into the gun holder, so that the top
of the taper on the gun handle is flush with
the edge of the gun holder.
d. Set gun height for the desired line width.
Adjust height by loosening the small black
handle on the gun holder assembly and slide
the gun arm to the correct height. Now
tighten the handle. This will require some
experimentation to find the correct height. It
is suggested that tape, or some other method
is used to mark the height of commonly used
settings.
e. Set spacing between the two guns by
loosening the black handle on the gun arm.
Slide to the desired width and tighten.
f. Attach the swivel heads to the guns if
painting curbs or wide stripes.
g. Angle the guns slightly forward. This allows
the spray pressure from the guns to help
blow dirt and debris out of the path of the
new stripes.
4. Cable TensionAdjustment
Once the handle and gun arm assemblies are set up to
the preferred positions, pressurize the unit and trigger
each gun to ensure that they activate and release
correctly. If not, adjust the cable tension as follows:
a. Locate the adjustment knobs on the base of the
gun trigger, where the cable connects to the gun
trigger assembly.
b. Loose the locking nut and move the adjusting
screw until the slack has been removed from the
cable.

1. Lock gun trigger.
2. Turn Rev-Tip handle 180 degrees.
3. Disengage trigger lock and trigger gun into pail.
4. If the Rev-Tip handles appears locked
(resists turning) loosen the retaining
nut. Then handle will now turn easily.
5. Engage trigger lock and return
handle to the spray position.
ADJUSTING SPRAY GUN
Hold gun with trigger locked (25) and push trigger against the
lock (17). Then adjust nut (15) so that the retainer (14) will
move freely back and forth approximately 1/32" to allow valve
spring unit (9) to seat the valve ball (8).
IMPORTANT: Readjust nut (15) periodically for
wear of valve seat (7) and valve ball (8); otherwise,
leakagewilloccur.

When removing and replacing valve seat (7), hold
the trigger (25) in the open position so that the valve
ball (8) is lifted off the valve seat. Failure to lift the
ball off the seat will result in a scratched leaky valve.
3. Unscrew valve ball (8) together with the brass part of
the assembly (9). Do not pull on the parts or the
packing may get damaged.
4. Unscrew the valve ball (8) from the brass part of the
assembly (9).
Reassembling is done in reverse sequence. Screw the new
valve ball with holder (8) into the brass part (9).
Tighten valve ball and brass part on threaded end
of the shaft by hand until you feel a positive stop.
Do not tighten with a wrench since this could
result in breaking the shaft.
Note: Itis recommended thatyouchange thevalve
seat (7) and valve ball (8) at the same time.
1. Repeat dismantling procedure as outlined above
under Steps 1 through 3.
2. Unscrew nut (15), remove retainer (14) with retainer
pins (13) and push shaft of the valve spring unit (9)
out of the gun head (12).
3. Clean gun head (12) bore with solvent and small
brush. Do not use any sharp objects to scrape away
dried paint, as they would cause leakage around the seal.
Reassembling is done in reverse sequence.
IMPORTANT: When reassembling, install valve
spring unit (9) with spring loose.
CLEANING 007 SPRAY GUN
Immediately after the work is finished, flush the gun out
with a solvent. Brush pins (13) with solvent and oil them
lightly so they will not collect dried paint.
TO REMOVE CLOGS- REVERSIBLE TIP
Push firmly into gun head by hand. Install retainer pins 13),
retainer (14) and nut (15) loosely onto valve spring unit
(9). By hand turn front of valve spring unit clockwise,
tightening the valve spring unit until you feel a positive
stop. At that point, continue tightening the valve spring
another 1/8 turn expanding the PTFE seals against body
of gun.
CLEANING FILTER
To clean the filter, use a brush dipped in as appropriate
solvent. Change or clean filters at least once a day .
Some types of latex may require a filter change after
four hours of operation.

Should the spray tip become clogged, relieve pressure
from hoses by following the "Pressure Relief Procedure"
in Machine Manual, secure the gun with safety lock (17),
take off Guard, take out the tip, soak in appropriate
solvent & clean with a brush. (Do not use a needle or
sharp pointed instrument to clean the tip. The tungsten

SPRAY TECHNIQUE - REGULAR AIRLESS SPRAYING
The closer the spray gun is held to the work, the
thicker the paint is deposited and the faster the gun
must be moved to prevent sags and runs. Holding
the gun too far from the work will cause excessive
fog, overspray, and a thin and grainy coat.
Good Spray Gun Technique is at the core of any
spray paint operation. Operator skill and efficiency
is as important as good equipment and good paint.
Good spray technique is a skill that can be quickly
learned by following these simple instructions.
If you are not familiar with spraying techniques,
we recommend that you study this section of your
manual and practice the proper technique on pieces
of cardboard or a suitable surface.
RIGHT WRONG
Equal spray distance
Equal amount of paint
Equal amount of paint
Equal spray distance
Hold gun straight up and down
TILTED GUN ANGLE
causes uneven paint coating
Shorter spray distance
Excessive paint spray
Insufficient paint spray
Longer spray distance
CORRECT DISTANCE
CORRECT GUN ANGLE
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.
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.

SPRAY TECHNIQUE - REGULAR AIRLESS SPRAYING
"Inside" and "outside" corners can be sprayed.
Aim the spray gun toward the center of the corner.
The spray pattern is divided in half, and the edges
of the spray pattern on both walls are the same.
Always use the lowest pressure possible to obtain
desirable results.
Test the spray pattern on a piece of cardboard or
other surface.
It is important to "trigger" the gun after gun movement
(arm movement) has started and release trigger (shut
gun off) before gun movement ends. Gun movement is
always longer than actual paint (spray) stroke. In that
manner, even blending and uniform paint coat thickness
is achieved over the entire surface. When the gun is in
motion as the trigger is pulled, it deposits an even
amount of paint.
Overlap the previous pass by half the width of the
spray pattern. Aim at the bottom of the previous pass.
Spray with uniform strokes from left to right and
from right to left, holding stroke speed, distance,
lapping, and triggering as uniform as possible.
Adjust pressure control knob so that paint is com-
pletely atomized from the spray gun. Insufficient
pressure will result in "tailing".
Too much pressure will result in excess fog and
overspray, excessive tip wear, and increased
sprayer wear and tear.
