Failure to follow all instructions listed below may result in electric shock, fire and/ or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work area safety

Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that may ignite dust or fumes.
keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric
shock.
If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of
electric shock. 

Personal safety

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
  Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
  If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
  Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a  fraction of a second.
Power tool use and care
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
 Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
 Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Service
  Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Safety instructions for fine spray systems
Keep your work area clean, well lit, and free of paint or solvent containers, clothes and other flammable materials. 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 environment.
Do not spray or clean with materials with a flash point lower than 55 °C. Use water-based materials, nonvolatile hydrocarbons or similar materials.
Volatile evaporating solvents create an explosive environment.
Do not spray near ignition sources such as static electricity 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 chemicals. Wearing personal protective equipment appropriate to the conditions reduces your exposure to hazardous substances.

 

Take note of possible risks posed by the spray material. Observe the markings on the container or the manufacturer’s information regarding the spray material, including the instructions about using personal protective 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.

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 determined according to
EN 62841-1.
Typically the A-weighted noise level of the power tool are: 84 dB(A); sound power level 95 dB(A). Uncertainty K = 3 dB.
Wear hearing protection
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 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 standardised 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 organising 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.
Connecting the air hose (see figures A1–A3)
– Open the holding clamp (24) and unwind the air hose (20) completely from the base unit (22).
Connecting the base unit:
– Insert a bayonet lock (21) of the air hose securely into the holes in the base unit port (26) according to the arrow marks.
– Turn the bayonet lock a quarter turn clockwise. Connecting to the spray gun:
– Insert the second bayonet lock (21) 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 (20) before pouring in spray material (quarter turn of the bayonet lock (21) anticlockwise; pull the bayonet lock (21) out of the port (9)).
Changing the nozzle cap (see figures B1–B2) The fine-spray system is supplied with three nozzle caps:

Delivery condition
Mounted In the accessory
compartment (27) under the
holding clamp (24)
Application “Wall” “Wood/glaze” “Wood/lacquer”

Note: Check the spray material by stirring it before selecting the nozzle cap. Thinner-viscosity material (e.g. wood paint) can be sprayed better with the grey nozzle cap (11) or the black nozzle cap (12), whereas thicker-viscosity material (e.g. 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 holding clamp (24) and take the required nozzle cap out of the accessory compartment (27).
– 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 neighbouring 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 spray 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, 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. 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-cir- cuit 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 flash point of the mixture is above 55 °C again after diluting. Diluting substances such as solvent-based lacquers lowers the flash point.
Note the specifications of the paint manufacturer relating to sprayability, e.g. in the technical information sheet or data sheet. 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 (20) before pouring in spray material (quarter turn of the bayonet lock (21) anticlockwise; pull the bayonet lock (21) out of the port (9)).
– When using large buckets, pour the spray material into a smaller transfer bucket (14) 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 (13) 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

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.
u Make sure that the base unit cannot draw in dust or other contamination during operation. u Make sure never to spray on the base unit.
u 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.
u 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.
– Switch on by pressing the on/off button (25).
– Set the on/off button (25) to the required application to regulate the air flow (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.
Switching off

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 quantity 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.
An 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 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)/(12) 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 (28) or a commercially available washing-up brush.
Setting the spray pattern (see figure I) u Never actuate the trigger switch (5) while adjusting the air cap (2).
– Turn the air cap (2) to the required position.
