Safety Warnings
GROUNDING
Ground the sprayer and other components in the system to reduce the risk of static sparking, re or
explosion which can result in serious bodily injury and property damage.
Always ground all of these components:
• Fluid Hose: use only grounded hoses.
• Spray gun or dispensing valve: grounding is obtained through connection to a properly
grounded uid hose and pump.
• Object being sprayed: according to your local code.
• All solvent pails used when ushing 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 un-pressurized 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 300 Ft. (150 m.) overall combined hose length to assure electrical continuity.
AVOID COMPONENT RUPTURE
This sprayer operates at 2500 psi (170 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 hoses. Do not allow kinking or crushing of hoses or allow
it to vibrate against rough, sharp or hot surfaces. Before each use, check hoses for damage and wear and ensure
all 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 ttings with your hand or any part of the body. Turn off the
unit and release pressure by following PRESSURE RELIEF PROCEDURE on page 10.
• ALWAYS use approved high pressure ttings and replacement parts.
• ALWAYS ensure re extinquishing equipment is readily available and properly maintained.
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:
Ethylchloride, Tethrachloethane. Alternate valves and guns are available
if you need to use these solvents.

Safety Warnings
FLUSHING
Reduce risk of injection injury, static sparking or splashing by following the specic cleaning procedure on page 7.
• ALWAYS follow the PRESSURE RELIEF PROCEDURE on page 10.
• ALWAYS remove the spray tip before ushing. Hold a metal part of the gun rmly to the side of a metal pail and
use the lowest possible uid pressure during ushing.
• NEVER use cleaning solvents with ash points below 140º F. Some of these are: acetone, benzene, ether,
gasoline and naphtha. Consult your supplier to be sure.
• NEVER smoke in the spraying/cleaning area.
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 re, do not plug in or unplug any
electrical cords in an enclosed 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 uid hoses for airless applications. Be sure gun is grounded through hose connections. Check
ground continuity in hose & equipment. Overall (end to end) resistance of un-pressurized 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.
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.
WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR PAINT THINNERS:
1. When spraying with ammable liquids, unit must be located a minimum of 25 feet away from spraying area
in a well ventilated area. Ventilation must be sufcient 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.

valve OFF.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water heaters and
other appliances that have pilot lights or other ignition
source. They can ignite gasoline vapors.
Starting engine creates sparking.
Sparking can ignite nearby ammable gases.
Explosion and re could result.
• If there is natural or LP gas leakage in area, do not
start engine.
• Do not use pressurized starting uids because vapors
are ammable.
Rapid retraction of starter cord (kickback) will pull
hand and arm toward engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
• When starting engine, pull cord slowly until resistance is
felt, then pull rapidly.
• Remove all external equipment/engine loads before starting
engine.
• Direct coupled equipment components such as, but not
limited to, blades, impellors, pulleys, sprockets, etc. must

remove the plastic cap plug from the outlet tee
at the spray pump, and screw a conductive or grounded
3000 psi airless spray hose onto uid outlet.
b. Connect an airless spray gun to the other end of
the hose.
c. Do not use steel braided airless hose. Use nylon
braided airless hose only.
NOTE: Do not use thread sealer on swivel
unions as they are made to self-seal.
Use thread seal on tapered male threads only.
2. Remove the snap-on cover plate
over the piston.
3. Grounding
WARNING
To reduce the risk of static sparking, re or
explosion which can result in serious bodily
injury and property damage, always ground
the sprayer and system components and the
object being sprayed, as instructed in the
safety warning section of this manual.
A small steel chain grounding strap is installed at
the factory to prevent static build-up.
4. Flush the sprayer
As per "Flushing Procedure" in this manual.
3. Fill the packing nut/wet cup with 5 drops
of Airlessco Throat Seal Oil (TSO) and
then reinstall snap-on piston cover plate
Failure to lubricate the piston properly
with throat seal oil can cause premature
wear and damage to piston and packings.
9
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 instruction
manual provided with your gun on its
safety features and how to engage safety latch.
2. Turn engine off using OFF switch on the engine.
3. Disengage safety latch & trigger gun to relieve
residual uid pressure. Hold metal part of the gun
in contact with grounded metal pail.
4. Re-engage gun safety latch.
5. Turn Control Valve (Prime/Pressure Relief Valve)
as shown open (priming) to relieve uid pressure.
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:
10
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.
3. Tighten suction nut daily.
Starting Up
1. Learn how to operate the control valve.
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 it’s maximum
output pressure of 2500 psi. This will fully atomize any stain or paint
without needing to dilute the material.
FOLLOW “PRESSURE RELIEF PROCEDURES”
ON PAGE 10 WHENEVER YOU:
- are instructed to relieve pressure
- stop spraying
- checking or servicing any of the system equipment.
- install or clean the spray tip.
To stop the unit in an emergency or
before performing any service or
maintenance procedure follow the
Pressure Relief Procedure on page 10
to relieve the uid pressure.
HANDLE THE SPRAY SYSTEM AS YOU
WOULD A LOADED FIREARM!!
2. Prepare the Material
d. Install spray tip onto gun.
e. If so equipped, turn engine switch to ON position, then
pull starter rope vigorously until engine starts.
e. Turn Control Valve clockwise to the desired spray pressure required to properly atomize your material
(Sprayer is limited to a maximum of 2500 psi).
f . Disengage the gun safety lock and you are ready to
start spraying.
5. Adjusting the Pressure
a. Turn the Control Valve clockwise to increase pressure and counterclockwise to decrease pressure.
If you spray into the paint bucket,
always use the lowest spray pressure
and maintain rm metal to metal
contact between gun and container.
a. Prepare the material according to the manufacturer’s
material recommendations.
b. Place the suction tube into the material container.
3. Starting the Sprayer (see Figure above)
a. Pressure Control Knob must be in the low pressure
position.
b. Control Valve must be open to the priming position or
fully counterclockwise.
c. Follow the procedure under “How to Flush”, Steps 6
through 12.
b. Always use the lowest pressure and engine RPM necessary to completely automize the material.
c. If wider 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 ow rate.
e. A trigger locking button is provided on the engine
speed and spray gun actuation levers to prevent hand
cramping and user fatigue during extended striping
sessions.
Operating the sprayer at higher engine RPM or
higher pressure than needed wastes material,
causes early tip wear and shortens engine and
sprayer pump life!
11
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. Cable Tension Adjustment
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 & move the adjusting screw until the slack has
been removed from the cable.
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 insufcient.
5. Miscellaneous Operations
CURBS: To paint at a 90 degree angle to spray the sides of curbs install
a part # 032-028 swivel between gun head and tip guard and aim guard
sideways towards the curb.
WIDE STRIPES: Install wider fan striping tips and raise the gun height
to achieve the desired width line.
STENCILS: Install standard spray tip on the outer gun. Rotate gun to
remove from the gun holder and use the gun to spray within your stencils.
Use of an extension pole will make this job a lot easier on the operators
back and is highly reccomended.
12
STANDARD PAINTING: Install the appropriate size and type of paint
spraying tip (standard paint spray, “W” wide pattern, or “Fine Finish”).
Remove gun and spray just as you do for stencils. Additional paint hose
may be required depending on the distance between the job and the
equipment.

DEFECTS CAUSE CORRECTION
Coarse spray Low pressure Increase the pressure
Excessive fogging High pressure Reduce pressure for satisfactory pattern(overspray) Material too thin Use less thinner
Pattern too wide Spray angle too large Use smaller spray angle tip
Pattern too narrow Spray angle too small Use larger spray angle tip. (If coverage is OK,
try tip in same nozzle group)
Too much material Tip size too large Use next smaller tipMaterial too thin
Pressure too high Reduce pressure
Too little material Tip size too small Use next larger tipMaterial too thick
Thin distribution in Worn tip Change for new tip
