Safety Notes

General Power Tool Safety Warnings

Workplace safety

  • Keep work area clean and well lit. Cluttered and dark area invite accidents.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to loose 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 and 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 safety equipment. Always wear eye protection. Safety equipment such as dusk 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 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.
  • 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, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

Use and care of the power tool

  • 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 the battery pack 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. 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.
  • Use the power tool, accessories and application tools etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of power tools for operations different from those intended could result in a hazardous situation.

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 Warnings for Fine-spray Systems
  • Keep area clean well lit and free of paint or solvent containers, rags, and other flammable materials. Spontaneous combustion may occur. Fire extinguisher equipment shall be present and working at all times.
  • Provide for good ventilation in the spraying area and for sufficient fresh air in the complete room. Evaporating inflammable solvents create an explosive environment.
  • Do not use materials with a flashpoint below 21 °C for spraying and cleaning. Use water-based materials, non-volatile hydrocarbons or similar materials. Fast evaporating solvents create an explosive environment.
  • Do not spray in the vicinity of ignition sources, such as static electricity sparks, open flames, pilot lights, hot objects, engines/motors, cigarettes and sparks from plugging in or unplugging power cords or operating switches. Such spark sources can ignite the spraying vicinity/environment.
  • Do not spray any liquid of unknown hazard potential. Unknown materials can create hazardous conditions.
  • Wear additional protective equipment such as appropriate protective gloves and protective masks or respirators when spraying or handling chemicals. Wearing protective equipment for the appropriate conditions re-duces the exposure to hazardous substances.
  • Never point the spray jet against yourself, towards other persons or animals. Keep your hands and other body parts away from the spray jet. If the spray jet should penetrate the skin, seek medical attention immediate-ly from a doctor. The material being sprayed can even penetrate the skin through a glove and be injected into your body.
  • Do not treat an injection as a simple cut. A high-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that an injection occurs, seek medical attention immediately.
  • Be aware of possible hazards from the spray material. Observe the information on drums/tanks/tins as well as manufacturer information of the spray material, including the request to wear personal protective equipment. The manufacturer’s instructions are to be observed in order to reduce the risk of fire as well as injuries caused through toxins, carcinogens, etc.
  • Use only nozzles/nozzle inserts specified by the manufacturer. Never spray without the nozzle protection mounted. Use of a special nozzle insert with the corresponding nozzle protection reduces the probability that a high-pressure jet penetrates the skin and injects toxins in-to the body.
  • Exercise caution when cleaning and changing nozzle inserts. If the nozzle insert should become clogged during spraying, follow the manufacturer’s instructions for switching off the system and relieving the pressure before removing the nozzle. Fluids under high pressure can penetrate the skin, inject toxins into the body and lead to serious injury.
  • Keep the plug of the mains cord and the trigger switch of the spray gun clear of paint and other fluids. Never hold the cord by its connectors to support it. Failure to follow the instruction can lead to electric shock.

Products sold in GB only: Your product is fitted with an BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an author-ised customer service agent. The replacement plug should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains sock-et elsewhere.
Products sold in AUS and NZ only: Use a residual current de-vice (RCD) with a rated residual current of 30 mA or less.

When purchasing paint, varnish and spray material, pay attention to their environmental compatibility.

Preparing the Spray Surface
Note: Cover off the vicinity of the spray surface thoroughly and generously.
The spray mist contaminates the environment. When spraying in enclosures, surfaces not covered can become contaminated.
The spray surface must be clean, dry and grease-free.

  • Roughen smooth surfaces and then remove the sanding dust.

Suitable spray materials and recommended diluting agents

  • When diluting, pay attention that the spray material and the diluting agent correspond. When using a faulty diluting agent, lumps can develop that can lead to clogging of the spray gun.

Spray Material

Recommended Dilution

Wood preservatives, mordants/strip-pers, oils, varnishes, impregnations, rust-protection primers

Undiluted

Disinfectants, plant protectants, water, wallpaper stripper

Undiluted

Solvent or water-dilutable paints, primers, radiator paint, automotive top coats, thick-coat finishes

At least 10% diluted

The tool is not suitable for processing dispersion paint (wall paint/latex).
Please also observe the practical advice/tips of the spray ma-terial manufacturers.

Diluting Spray Material
For spray material that needs to be diluted, proceed as follows:

  • Take the measuring cup 22.
  • Stir the spray material thoroughly.
  • Fill a sufficient quantity of spray material into the spray-material container 11.
  • Dilute the spray material by 10% with paint thinner.
  • Stir the spray material thoroughly.
  • Carry out a test-spray run on a test surface.

When the spraying pattern is perfect, start the spray job.
or
When the spraying result is not satisfactory or when no paint comes out, please continue as described under “Correction of Malfunctions”.

Filling in Spray Material
  • Before any work on the machine itself, pull the mains plug.
    • Unscrew the container 11 from the spray gun.
    • Turn the suction tube 10 so that the spray material can be sprayed with almost no residue.
    • Fill the spray material into the container and screw the container firmly to the spray gun.

Starting Operation

  • Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230V can also be operated with 220V.
  • Pay attention that the power tool cannot draw in dust or other contamination during operation.
Switching On
  • Plug the mains plug into a socket outlet.
  • Grasp the power tool and point it at the spray surface.

The power tool is equipped with a two-step trigger switch 16. The first step starts the turbine. The second step transports the spraying material.

  • Pull the trigger switch 16 until spraying material starts to come out.
Switching Off
  • Release the trigger switch 16.
  • Pull the mains plug from the socket outlet.

Working Advice

Spraying

Note: Observe the wind direction when operating the power tool outdoors.

  • Firstly, carry out a test-spray run and adjust the spray pat-tern and the spray material quantity according to the spray material. (For adjustments, see the following sections)
  • Make sure to hold the spray gun vertical to the spray object at a uniform clearance between 5 – 15 cm.
  • Begin the spraying procedure outside the target area.
  • Move the spray gun evenly cross-wise or up-and-down, de-pending on the spray pattern setting.
    An even surface quality is achieved when the paths overlap by 4-5cm.
  • Avoid interruptions within the spray surface.

Guiding the spray gun evenly will provide uniform surface quality.
Non-uniform clearance and spray angle lead to heavy formation of paint mist and thus to an uneven surface.

  • End the spraying procedure outside the target area.

Never spray the container completely empty. When the suction tube no longer immerses in the spray material, the spray jet will break off, resulting in a non-uniform surface.
When coating material builds up on the nozzle and air cap, clean both parts with the corresponding solvent.
Note: Only place down the power tool on a level and clean sur-face so that it can not tip over.

Adjusting the Spray Pattern
  • Never actuate the trigger switch 16 while adjusting the air cap 13.
    • Loosen the union nut 14.
    • Turn the air cap 13 to the requested position.
    • Firmly retighten the union nut.
