Safety instructions for fine spray systems

  • Keep your work area clean, well lit, and free of paint or solvent containers, clothes, and other flammable mater­ There is a risk of spontaneous combustion. Ensure that you have access to functioning fire extinguishers or extinguishing equipment at all times.
  • Ensure that the spray area is well ventilated and that there is sufficient fresh air circulating in the whole area. Evaporating flammable solvents create an explosive
  • Do not spray or clean with materials with a flash point lower than 55 °C. Use water-based materials, non-volatile hydrocarbons, or similar materials. Volatile
    evaporating solvents create an explosive environment.
  • Do not spray near ignition sources such as static elec­ tricity sparks, naked flames, pilot lights, hot objects, engines, cigarettes, and sparks created by plugging in and unplugging electric cables or operating switches. These kinds of spark sources can lead to the combustion of the surrounding environment.
  • Do not spray materials if it is not clear whether they might be dangerous. Unknown materials could create hazardous conditions.
  • Do not spray boiling water. Spray only warm water (max. 55 °C) which is free from chemical additives.
  • Wear additional personal protective equipment such as appropriate protective gloves and a protective mask or respirator when spraying or handling chemic­ Wearing personal protective equipment appropriate to the conditions reduces your exposure to hazardous substances.
  • Take note of possible risks posed by the spray mater­ Observe the markings on the container or the man­ ufacturer’s information regarding the spray material, including the instructions about using personal pro­ tective equipment. You must comply with the manufac­turer’s instructions in order to reduce the risk of fire and of injury caused by poison, carcinogens, etc.
  • Keep the mains plug and the spray system trigger switch free from paint and other liquids. Never hold the cable by its plug connection for support. Doing this could cause electric shock.
  • Supervise children. This will ensure that children do not play with the fine spray system.

The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Noise/Vibration Information
Noise emission values were determined according to EN 62841-1.
Typically, the A-weighted sound pressure level of the power tool is 80 dB(A). Uncertainty K = 3 dB. The noise level when working can exceed the volume stated. Wear hearing protection!
Vibration total values  ah (triax vector sum) and uncertainty K determined according to 62841-1: ah < 2.5 m/s 2 , K = 1.5 m/s 2 
The vibration level and noise emission value given in these instructions have been measured in accordance with a standardized measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different
application tools, or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organizing workflows correctly.

Assembly

  • Pull the plug out of the socket before carrying out any work on the power tool.
  • Ensure that the spray gun and base unit are assembled completely and with all seals. Only this will ensure the function and safety of the fine-spray system.
  • Ensure that a nozzle cap that was delivered with the spray gun is fitted. Only this will ensure the function and safety of the fine-spray system.

Connecting the Air Hose (see figures A1–A3) 
– Open the elastic band (28) and completely unwind the air hose (19).
Connecting the base unit:
– Insert a bayonet lock (20) of the air hose securely into the holes in the base unit port (29) according to the arrow marks.
– Turn the bayonet lock a quarter turn clockwise.
Connecting to the spray gun:
– Insert the second bayonet lock (20) of the air hose securely into the holes in the spray gun port (9) according to the arrow marks.
– Turn the bayonet lock a quarter turn clockwise.
Note: Remove the air hose (19) before pouring in spray material (quarter-turn of the bayonet lock (20) anticlockwise; pull the bayonet lock (20) out of the port (9)).

Changing the Nozzle Cap (see figures B1–B2) 
The fine-spray system is supplied with two nozzle caps:

Nozzle cap
(10) (11)
Paint White Grey
Delivery condition Mounted In the accessory compartment (30) under the air filter cover (26)
Application “Wall” “Wood”

Note: Check the spray material by stirring it before selecting the nozzle cap. Thin-viscosity material (e.g. wood paint) can be sprayed better with the grey nozzle cap (11). Thick-viscosity material (e.g. wood lacquer or wall paint) can be sprayed better with the white nozzle cap (10).

– To change the nozzle cap, unscrew the cap nut (3).
– Pull off the air cap (2).
– Unscrew the mounted nozzle cap.
– Open the air filter cover (26) and take the required nozzle cap out of the accessory compartment (30).
– Screw the required nozzle cap into the thread in the spray gun.
– Put the air cap (2) on the nozzle cap and tighten it with the cap nut (3).

Operation

  • Pull the plug out of the socket before carrying out any work on the power tool.
  • Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.

Work preparation

  • Spraying on the sides of water bodies (lakes, rivers, etc.) or neighboring surfaces in the direct catchment area is not permitted.
  • When purchasing paint, lacquer, and spray material, pay attention to their environmental compatibility.

Preparing the spray surface
The sprayed surface must be clean, dry, and grease-free.
– Roughen smooth surfaces and then remove the sanding dust.
When spraying, all non-covered surfaces can be contaminated by the spray mist. Therefore, thoroughly prepare the area around the surface to be sprayed:
– Carefully cover floors, furnishings, doors, and windows as well as door and window frames, etc. Painting substrate, for example, is recommended for covering the floors.
– Fix the cover material in place. A cover material that is not fixed in place securely can be detached or blown away by the powerful air jet.

  • Carefully mask off plug sockets and switches. Uncovered plug sockets and switches may cause a short circuit and increase the risk of electric shock.

Preparing the spray material

  • When diluting, make sure that the spray material and the diluting agent are compatible. When using a faulty diluting agent, lumps can develop that can lead to clogging of the spray gun.
  • When diluting the spray material, make sure that the flashpoint of the mixture is above 55 °C again after diluting. Diluting substances such as solvent-based lacquers lower the flashpoint.
  • Note the specifications of the paint manufacturer relating to sprayability, e.g. in the technical information sheet or datasheet. Make sure that you do not spray any paints that are not suitable according to the manufacturer’s specifications.
    – Stir the spray material thoroughly.
    Using spray material at room temperature will yield a better spray pattern.
    – Dilute the spray material if necessary.
    If the spray test does not produce a good spray pattern, dilute in 5 % increments until an optimal spray pattern is achieved.

Filling the spray material (see figures C1–C2)
Note: Remove the air hose (19) before pouring in spray material (quarter-turn of the bayonet lock (20) anticlockwise; pull the bayonet lock (20) out of the port (9)).
– When using large buckets, pour the spray material into a smaller transfer bucket (13) if necessary (e.g. 10 l wall paint into an empty 2.5 or 5.0 l bucket).
– Hold the spray gun in place with one hand and use the other hand to turn the container (7) towards the open symbol.
– Pull the spray gun off the container (7).– If you are using already opened spray material, place the thoroughly cleaned filling sieve (12) on the container (7) to hold back any lumps of paint when pouring in.
– Pour the spray material into the container (7) up to no more than the 1000 mark.
– Put the spray gun on the container (7). Turn the container (7) towards the close symbol until you hear the lock ring (6) engage. – Carry out a test-spray run on a test surface. If the spray pattern is optimal, you can begin spraying. or
If the spraying results are unsatisfactory or no paint is emitted: (see “Troubleshooting”, page 26)

Starting Operation

  • Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the power tool.
  • Make sure that the base unit cannot draw in dust or other contamination during operation.
  • Make sure never to spray on the base unit.
  • Stop spraying if fluid escapes from places other than the intended nozzle during spraying, and restore the spray gun to its proper condition. There is a risk of electric shock.
  • Do not direct the fine-spray system against yourself, other persons, or animals.

Switching On (see figure D)
– Check whether the correct nozzle cap is fitted (see “Changing the Nozzle Cap (see figures B1–B2)”, page 22).
– Plug the mains plug into a plug socket.
– Grasp the spray gun by the handle and point it at the target area.
– Set the sliding switch (25) to the required application to regulate the airflow (see “Setting the Air Flow (see figure D)”, page 24).
– Pull the trigger switch (5) on the spray gun.
Note: Air always flows out at the air cap (2) when the base unit is switched on.

– Pull the mains plug from the plug socket.

Working Advice
Spraying (see figures E–H)
Note: Pay attention to the wind direction when you are using the power tool outdoors.
– Firstly, carry out a spray test and adjust the spray pattern and the spray material volume according to the spray material. For adjustments, see the following
sections.
– Make sure to hold the spray gun with a uniform clearance of 20–25 cm vertical to the object being sprayed.
– Begin the spraying procedure outside the target area.
– Move the spray gun evenly horizontally or vertically according to the spray pattern configuration.
Even surface quality can be achieved when the spray paths overlap by 4–5 cm.
– When spraying horizontal objects or spraying overhead, hold the spray gun at a slight angle and move back from the sprayed surface.
Risk of tripping! Be aware of potential obstacles. 
– Avoid interruptions when spraying the target area. Guiding the spray gun evenly will provide uniform surface quality.
A non-uniform spraying angle and distance will lead to a heavy formation of paint mist and consequently an uneven surface.
– End the spraying procedure outside the target area.
Never completely empty the container for the spray material by spraying. If the suction tube is no longer immersed in the spray material, the spray jet will be interrupted and this will result in an inconsistent surface.
– After breaks or refilling the container (7), check the nozzle cap (10)/(11) and the air cap (2) and clean them if required.
– If spray material settles on the air cap (2) or the nozzle cap, clean the components with the supplied cleaning brush (27) or a commercially available washing-up brush.

Setting the spray pattern (see figure I)
• Never actuate the trigger switch (5) while adjusting the air cap (2).
– Turn the air cap (2) to the required position.
