These have a strong wear and tear eect on valves, high-pressure

appreciably through this.
3. Description of unit
3.1 Airless process
The main area of application are thick layers of highly viscous coating
material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it
to the tip. Pressed through the tip at very high pressures, the coating
material is atomized. This high pressure has the eect of micro ne
atomization of the coating material.

The inlet valve is opened automatically by the upwards movement

downward.
The coating material ows under high pressure through the high-

the tip it atomises.

Proper earthing (grounding) is important. The
passage of some materials through the nylon uid
hose will build up a static electric charge, which if
discharged, could ignite solvent vapors present and
create an explosion.

9. Strain all paints with a nylon strainer to ensure trouble free
operation and freedom from frequent cleaning of the inlet
screen and gun lter.
10. Make sure the spray area is well ventilated to prevent
hazardous operation with volatile solvents or exhaust fumes.
If lacquer or other flammable materials are to be
sprayed, ALWAYS locate the compressor outside the
immediate spraying area. Failure to do so may cause
an explosion.

Attention
Always keep the trigger lock on the spray gun in the

1. Place the siphon tube into a container of the appropriate
solvent for the material being sprayed.
iIf you are spraying a water-based latex, ush with

4.3 Preparing a New Sprayer
If this unit is new, it is shipped with test uid in the uid section to
prevent corrosion during shipment and storage. This uid must be
thoroughly cleaned out of the system with cleaning agent before you
begin spraying.
Attention
Always keep the trigger lock on the spray gun in the
locked position while preparing the system.
1. Place the siphon tube into a container of mineral spirits.
2. Place the bleed hose into a metal waste container.

The flow from the spray tip is at very high pressure.
Contact with any body part may be dangerous. Do
not place finger on gun outlet. Do not point the gun
at any person. Never operate the spray gun without
the proper tip guard.
5. Cleanup
Attention
The sprayer, hose, and gun should be cleaned
thoroughly after daily use. Failure to do so permits
material to build up, seriously aecting the
performance of the unit.
Always spray at minimum pressure with the gun
nozzle tip removed when using mineral spirits or
any other solvent to clean the sprayer, hose, or
gun. Static electricity buildup may result in a re or
explosion in the presence of ammable vapors.

For long-term or cold weather storage, pump
mineral sprits through the entire system.
16. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual.
17. Store the sprayer in a clean, dry area.
Attention
Do not store the sprayer under pressure.
5.3 Cleaning the Air Filter
The air lter blocks any debris or particles that might be present in
the supplied air from the air compressor. It is important that this lter
be checked after every use.
1. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual.
