Safety Precautions
This manual contains information that must be read and
understood before using the equipment. When you come to an
area that has one of the following symbols, pay particular
attention and make certain to heed the safeguard.
Attention! Danger of injury by injection!
In case of injury to skin caused by coating materials or
solvents consult a doctor immediately. Inform the doctor of the
type of coating material or cleaning agent with which the injury
was caused.
The operating instructions state that the following points
must always be observed before starting up:
1. Faulty units should not be used.
2. Secure spray gun using the safety catch on the trigger.
3. Ensure that the unit is properly earthed.
4. Check the permissible operating pressures.
5. Check all connections for leaks.
The instructions regarding regular cleaning and
maintenance of the unit must be strictly observed.
Before any work is done on the unit or for every break in
work the following rules must be observed:
1. Release the pressure from the spray gun and hose.
2. Secure the spray gun using the safety catch on the
trigger.
3. Turn off the motor.
Be safety-conscious!
All local regulations in force must be observed.
In order to ensure safe operation of the airless systems
the safety regulations listed below must be followed:
1. In order to avoid dangers, read the operating instructions
carefully and follow the instructions laid down in them.
2. Do not use materials with a flash point below 21ºC (70ºF).
3. The use of this unit is prohibited in workshops which are
covered under the explosion prevention regulations.
4. Never spray near sources of ignition; e.g. open flames,
cigarettes — also cigars and pipes are sources of ignition
— sparks, hot wires and hot surfaces, etc.
5. Attention! Danger of injury by injection!
Never point the spray gun at yourself or anyone else.
Never put your fingers or hands into the spray jet. The
very high spraying pressures can cause very serious
injuries. Never use the spray gun without the safety guard.
WARNING
This symbol indicates a potential hazard that may cause
serious injury or loss of life. Important safety information
will follow.
CAUTION
This symbol indicates a potential hazard to you or to the
equipment. Important information that tells how to prevent
damage to the equipment or how to avoid causes of minor
injuries will follow.
NOTE: Notes give important information which should
be given special attention.
WARNING
Airless units develop extremely high spraying pressures.
• Never put your fingers, hands or any other parts of the
body into the spray jet.
• Never point the spray gun at yourself or anybody else.
• Never use the spray gun without the safety guard.
When installing and removing the tip and during breaks in
work the spray gun must always be secured, so that it
cannot be activated.
6. Wear respiratory equipment when spraying. The operator
must be provided with a protective mask.
In order to prevent work related illness, the manufacturer's
regulations for the materials, solvents, and cleaning
agents used must be observed when preparing, working
with and cleaning the unit. Protective clothing, gloves and,
in certain cases, protective skin cream are necessary to
protect the skin.
7. The spray gun and high pressure hose between the unit
and spray gun must be of a sufficient standard for the
pressure produced in the unit.
The permissible operating pressure for the high-pressure
hose, the manufacturer and date of manufacture must be
indicated by a permanent identification marking on the
hose. Furthermore, it must be constructed so that the
electrical resistance between the connections to the unit
and the spray gun is equal to or less than one megohm.
8. Under certain conditions the flow speed can cause an
electrostatic charge on the unit. This could cause sparks
or flames on discharging. It is, therefore, important that
the unit is always earthed over the electrical installation.
The contact should be made using a shockproof socket
earthed in accordance with the regulations.

9. Attention! Please observe the following when working
inside and outside:
No solvent gasses should be carried to the unit. No
solvent gasses should form near the unit. Set up the unit
on the opposite side to the object being sprayed. When
spraying outdoors, take the wind direction into account.
When working indoors there must be sufficient ventilation
to ensure that the solvent gasses are carried away. A
minimum distance of 6.1m (20’) must be observed
between the unit and object being sprayed.
10. Extraction equipment should be installed by the user in
accordance with the local regulations.
11. The objects being sprayed must be earthed.
12. When cleaning the unit, solvent should never be sprayed
into a container with only a small opening (bunghole). An
explosive gas/air mixture is likely to form. The container
must be earthed.
13. Cleaning the unit.
A harsh jet should never be used to spray the unit. In
particular a high-pressure cleaner or high-pressure steam
cleaner should never be used. There is a danger that
water will penetrate into the unit and cause a short-circuit.
14. Pulling the trigger causes a recoil force to the hand that is
holding the spray gun.
The recoil force of the spray gun is particularly powerful
when the tip has been removed and a high pressure has
been set on the airless high-pressure pump. Therefore,
when cleaning without tip set the pressure control valve to
the lowest pressure.
15. The mains plug should always be disconnected from the
socket when work is being carried out on the electrical
components.
16. Work or repairs should only be carried out on electrical
equipment by a trained electrician, even if the work is
described in the operating instructions. No liability will be
accepted for incorrectly installed electrics.
17. Positioning when the ground is uneven.
The front of the unit must point downward so that the
machine does not slip away.
HAZARD: INJECTION INJURY - A high pressure stream
of paint produced by this equipment can pierce
the skin and underlying tissues, leading to
serious injury and possible amputation.
DO NOT TREAT AN INJECTION INJURY AS A
SIMPLE CUT! Injection can lead to
amputation. See a physician immediately.
PREVENTION:
• The maximum operating range of the unit is 228 BAR
(3300 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 your hand in front of the gun. Gloves will not
provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut the fluid pump off and
release all pressure before servicing, cleaning the tip
guard, changing tips, or leaving unattended. Pressure will
not be released by turning off the engine. The
PRIME/SPRAY knob must be turned to PRIME to relieve
the pressure. Refer to the PRESSURE RELIEF
PROCEDURE described in this manual.
• The tip guard must always be in place while spraying. The
tip guard provides some protection against injection
injuries but is mainly a warning device.
• ALWAYS remove the spray tip before flushing or cleaning
the system.
• The paint hose can develop leaks from wear, kinking and
abuse. A leak is capable of injecting material into the skin.
Inspect the paint hose before each use.
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.
HAZARD: EXPLOSION OR FIRE - Solvent and paint fumes
can explode or ignite, causing property damage
and/or severe injury.
PREVENTION:
• Fire extinguishing equipment must be present and in good
working order.
• Use only conductive or earthed high pressure fluid hoses
for airless applications. Be sure that the gun is earthed
properly through hose connections.
• The pump must be connected to an earthed object. Use
the green earthing wire to connect the pump to a water
pipe, steel beam, or other electrically earthed surface.
• When flushing equipment use the lowest possible
pressure.
HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE
MATERIALS- May cause property damage or
severe injury.
PREVENTION:
• Do not use bleach.
• Do not use halogenated hydrocarbon solvents such as
methylene chloride and 1,1,1 - trichloroethane. They are
not compatible with aluminum and may cause an
explosion. If you are unsure of a material’s compatibility
with aluminum, contact your coating's supplier.
HAZARD: GENERAL - May cause property damage or
severe injury.
PREVENTION:
• This high pressure airless pump is designed to be used
with manufacturer 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, as well as damage or movement of
couplings. If any of these conditions exist, replace the
hose immediately. Never repair a paint hose. Replace it
with another earthed hose.
• Wear protective eyewear.
• Do not spray on windy days.
Earthing Instructions
This product must be earthed. In the event of an electrical
short circuit, earthing reduces the risk of electric shock by
providing an escape wire for the electric current. This product
is equipped with a cord having an earthing wire with an
appropriate earthing plug. The plug must be plugged into an
outlet that is properly installed and earthed in accordance with
all local codes and ordinances.
DANGER — Improper installation of the earthing plug can
result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not
connect the green earthing wire to either flat blade terminal.
The wire with insulation having a green outer surface with or
without yellow stripes is the earthing wire and must be
connected to the earthing pin.
Check with a qualified electrician or serviceman if the earthing
instructions are not completely understood, or if you are in
doubt as to whether the product is properly earthed. Do not
modify the plug provided. If the plug will not fit the outlet, have
the proper outlet installed by a qualified electrician.

Electronic Pressure Control Indicators
The following is a description of the electronic pressure control
indicators.
Spraying Technique
The following techniques, if followed, will assure professional
painting results.
Hold the gun perpendicular to the surface and always at equal
distance from the surface. Depending on the type of material,
surface, or desired spray pattern, the gun should be held at a
distance of 30 to 35 cm (12 to 14 inches).
Move the gun either across or up and down the surface at a
steady rate. Moving the gun at a consistent speed conserves
material and provides even coverage. The correct spraying speed
allows a full, wet coat of paint to be applied without runs or sags.
Holding the gun closer to the surface deposits more paint on
the surface and produces a narrower spray pattern. Holding
the gun farther from the surface produces a thinner coat and
wider spray pattern. If runs, sags, or excessive paint occur,
change to a spray tip with a smaller orifice. If there is an
insufficient amount of paint on the surface or you desire to
spray faster, a larger orifice tip should be selected.
Maintain uniform spray stroke action. Spray alternately from
left to right and right to left. Begin movement of the gun before
the trigger is pulled.

For corners and edges, split the
center of the spray pattern on the
corner or edge and spray vertically
so that both adjoining sections
receive approximately even
amounts of paint.
When spraying with a shield, hold it firmly against the surface.
Angle the spray gun slightly away from the shield and toward
the surface. This will prevent paint from being forced
underneath.
Shrubs next to houses should be tied back and covered with a
canvas cloth. The cloth should be removed as soon as possible.
gun extensions are extremely helpful in these situations.
Nearby objects such as automobiles, outdoor furniture, etc.
should be moved or covered whenever in the vicinity of a
spray job. Be careful of any other surrounding objects that
could be damaged by overspray.

Fan widths measuring 8" to 12" (20 to 30 cm) are preferred
because they offer more control while spraying and are less
likely to plug.
Piston Lube
Specially formulated to prevent materials
from adhering to the piston rod, which
becomes abrasive to the upper seals.
Piston Lube will break down any material
that may accumulate in the oil cup and
keep it from drying.
Accessories
Airless Tip Selection
Tips are selected by the orifice size and fan width. The proper
selection is determined by the fan width required for a specific
job and by the orifice size that will supply the desired amount
of fluid and accomplish proper atomization.
For light viscosity fluids, smaller orifice tips generally are
desired. For heavier viscosity materials, larger orifice tips are
preferred. Please refer to the chart below.
