IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS – To reduce the risks of fire or explosion,
electrical shock, and the injury to persons, read and understand all instructions
included in this manual. Be familiar with the controls and the proper usage of the
equipment.
WARNING – To reduce the risk of fire or explosion:
1. Do not spray flammable or combustible materials near an open flame or sources
of ignition such as cigarettes, motors, and electrical equipment.
2. For units intended for use with only water-based materials - Do not spray or
clean with flammable liquids. For use with water-based liquids only.
3. For units intended for use with only water-based or mineral spirit-type materials
with a minimum flash point of 38°C) - Do not spray or clean with liquids having a
flash point less than 38°C.
4. Paint or solvent flowing through the equipment is able to result in static
electricity. Static electricity creates a risk of fire or explosion in the presence of
paint or solvent fumes. All parts of the spray system, including the pump, spray
gun, and objects in and around the spray area shall be properly grounded to
protect against static discharge and sparks.
5. Do not use a paint or a solvent containing halogenated hydrocarbons. See
operating instructions for examples of these types of materials.
6. Keep spray area well ventilated. Keep a good supply of fresh air moving through
the area. Keep pump assembly in a well-ventilated area. Do not spray pump
assembly.
7. Do not smoke in the spray area.
8. Do not operate light switches, engines, or similar spark producing products in
the spray area.
9. Keep area clean and free of paint or solvent containers, rags, and other
flammable materials.

10. Know the contents of the paints and solvents being sprayed. Read all Material
Safety Data Sheets (MSDS) and container labels provided with the paints and
solvents. Follow the paint and solvent manufacturer’s safety instructions.
11. Fire extinguisher equipment shall be present and working.
WARNING – To reduce the risk of skin injection:
1) Do not aim the gun at, or spray any person or animal.
2) Keep hands and other body parts away from the discharge. For example, do not
try to stop leaks with any part of the body.
3) Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.
4) Only use a nozzle tip specified by the manufacturer.
5) Use caution when cleaning and changing nozzle tips. In the case where the
nozzle tip clogs while spraying, follow the manufacturer’s instructions for turning
off the unit and relieving the pressure before removing the nozzle tip to clean.
6) Do not leave the unit energized or under pressure while unattended. When the
unit is not in use, turn off the unit and relieve the pressure in accordance with the
manufacturer’s instructions.
7) High-pressure spray is able to inject toxins into the body and cause serious
bodily injury. In the event that injection occurs, seek medical attention immediately.
8) Verify that all connections are secure before operating the unit.
9) Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar
with the controls.
WARNING – To reduce the risk of injury:
1) Always wear appropriate gloves, eye protection, and a respirator or mask when
painting.
2) Do not operate or spray near children. Keep children away from equipment at all
times.
3) Do not overreach or stand on an unstable support. Keep effective footing and

- 5 -
balance at all times.
4) Stay alert and watch what you are doing.
5) Do not operate the unit when fatigued or under the influence of drugs or alcohol.
Household Use Only
SERVICING OF A DOUBLE-INSULATED PRODUCT
In a double-insulated product, two systems of insulation are provided instead of
grounding. No grounding means is provided on a double-insulated product, nor
should a means for grounding be added to the product. Servicing of a
double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel. Replacement parts for a
double-insulated product must be identical to those parts in the product.
WARNING: WHEN A COMBUSTIBLE LIQUID IS SPRAYED THERE MAY BE
DANGER OF FIRE OR EXPLOSION, ESPECIALLY IN A CLOSED AREA. READ
INSTRUCTION MANUAL BEFORE OPERATING.
WARNING: DO NOT SPRAY ELECTRICAL APPARATUS AND WIRING.
DO NOT IMMERSE IN WATER OR SOLVENT.

Start-up
Before connecting to the mains supply, be sure that the supply voltage is identical
with the value given on the rating plate.
Unscrew the container from the spray gun.
Aligning suction tube. (Fig. 2)
If the suction tube is positioned correctly, the container contents can be sprayed
without almost any residue.
When working on lying objects: Turn the suction tube forwards. (Fig. 2 A)
Spraying work when working on overhead objects: Turn the suction tube
rearwards. (Fig. 2 B)
Set the container on a sheet of paper, pour in the prepared coating material and
screw the container tightly onto the spray gun.
Put the machine on a level, clean surface. Otherwise the machine could tip
over!
Adjust the spray setting on the spray gun.
Three different spray jet settings can be chosen on the spray gun,
depending on the application and target object.
Selecting the Spray Setting
Fig. 3 A = horizontal fat jet
Fig. 3 B = vertical fat jet
Fig. 3 C = circular jet
Adjusting the desired Spray Setting (Fig. 4)
Turn the air cap to the desired spray setting position.
The spray pattern indication can be found on the front part of the sprayer. With the
arrowhead towards the boss on the tip.( Fig. 4)
IMPORTANT! The air cap only can be turned at an angle . Do not
force.

WARNING! Danger of injury! Never pull the trigger guard
while adjusting the air cap.
Adjusting the Material Volume (Fig. 5)
Set the material volume by turning the regulator on the trigger guard of the spray
gun.
- turn to downside lower material volume
+ turn to upside higher material volume
Spray Technique
The spray result depends heavily on the smoothness and cleanliness of the
surface to be sprayed. Therefore the surface should be carefully prepared and
kept free of dust.
Cover all surfaces not to be sprayed.
Cover screw threads or similar parts of the target object.
It is advisable to test the spray gun on cardboard or a similar surface to find
the correct setting.
Important: Begin spraying outside of the target area and avoid
interruptions inside the target area.
Correct (Fig. 6a). Be sure to hold the spray gun at an even distance of approx.
10 – 30 cm to the target object.
Incorrect (Fig. 6b). Heavy spray fog build-up, uneven surface quality.
Move the spray gun evenly cross-wise or up-and-down, depending on the
spray pattern setting.
An even movement of the spray gun results in an even surface quality.
When coating material builds up on the nozzle (A) and air cap (B) (Fig. 7),
clean both parts
with a solvent or water.

Taking Out of Operation and Cleaning
Proper cleaning is the prerequisite for problem-free operation of the paint
application device. No warranty claims are accepted in case of improper or no
cleaning.
1) Unplug the power plug. Turning open the canister and pulling the trigger guard
and letting the paint into the original paint container.
2) Divide the spray gun. Press the unlock button (Fig. 8) downwards. Pull out
the front part of the spray gun.
3) Unscrew the container. Empty any remaining coating material back into the
material tin.
4) Preclean the container and suction tube with a brush.
5) Pour solvent or water into the container. Screw the container back on. Use only
solvents with a flashpoint over 38°C .
6) Assemble the gun again.
7) Insert the power plug, turn on the machine and spray the solvent or water into
a container or a cloth.
8) Repeat the above procedure until the solvent or water emerging from the
nozzle is clear.
9) Turn off the machine and remove the plug.
CAUTION!
Never clean the seals, nozzles, or air holes of the spray gun with
metal objects.
The seal parts are only solvent-resistant to a limited extent. Do
not immerse in solvent, only wipe.
WARNING! Never hold the spray gun rear part under water or
immerse it into liquids. Clean the housing only with a moistened
cloth.
10) clean the outside of the spray gun and container with a cloth soaked in solvent
or water.
11) Unscrew the union nut and remove the air cap and nozzle. Clean the air cap
and nozzle with a brush and solvent or water and assemble back. Pay attention to
the rib and should be fitted in the slot on the base (Fig 9).
