General Safety Instructions:

For your own protection and for the protection of your electrical tool, pay attention to all parts of the text that are marked with this symbol!

WARNING – Reading the operating instruc-tions will reduce the risk of injury.

WARNING – Read all safety warnings, instructions, illustrations and specifications provided with this power tool. 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. Pass on your electrical tool only together with these documents.

• Always wear protective goggles.
• Secure the workpiece with clamping devices to prevent slipping.
• Use both hands on the handles provided to guide the machine and avoid loss of control.
• Avoid placing hands near rotating parts of the device or the sanding belt.
• Clean sanding dust only when the machine is not in operation.
• Disconnect from the power source before making any adjustments, conversions, or servicing.
• Keep all warnings and instructions for future reference.

Special Safety Instructions

• Hold the power tool with insulated gripping surfaces, because the sanding surface may contact its own cord.
  Cutting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock. Flying sparks are created when sanding metal. Ensure that no persons are in danger. Due to the risk of fire, all combustible materials must be removed from the work area (area affected by flying sparks).

• During machining, of metals, in particular, conductive dust can form deposits inside the machine. This can lead to the transfer of electrical energy onto the machine housing. This can mean a temporary danger of electric shocks. This is why it is necessary when the machine is running to blow compressed air through the rear ventilation slots of the machine regularly, frequently, and thoroughly. Here, the machine must be held firmly.

• We recommend using a stationary extractor system and connecting a residual current circuit-breaker (FI) upstream. When the machine is shut down via the FI circuit breaker, it must be checked and cleaned.
  See Chapter 8. Cleaning for more information on cleaning the motor. Wear ear protectors. Exposure to noise can cause hearing loss.
  Wear protective gloves.
  Always wear protective goggles.

• Secure the workpiece against slipping, e.g. with the help of clamping devices.

• Always guide the machine with both hands on the handles provided. Loss of control can cause personal injury.

• Never place your hand near rotating parts of the device or near the rotating sanding belt.

• Remove sanding dust and similar material only when the machine is not in operation.

• Pull the plug out of the plug socket before any adjustments, conversions or servicing are performed.

• The rated speed of the sanding belt must be at least equal to the belt speed in idling marked on the power tool. A sanding belt running faster than its rated speed can break and fly apart.

• Check prior to each use that the sanding belt is correctly attached and is completely on the rollers. Carry out a trial run: Allow the machine to run at idling speed for 30 seconds in a safe location. Stop immediately if significant vibrations occur or if other defects are noted. If such a situation occurs, check the machine to determine the cause.

Reduce dust exposure:

• Particles generated when working with this machine may contain substances that can cause cancer, allergic reactions, respiratory diseases, birth defects or other propagation defects. Some of these substances include: Lead (in paint containing lead), mineral dust (from bricks, concrete, etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos. The risk depends on for how long the user or nearby persons are exposed to the substance.

• This dust must not be allowed to enter your body. Do the following to reduce exposure to these substances: Ensure good ventilation of the workplace and wear appropriate protective equipment, such as respirators able to filter microscopically small particles.
  Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).

• Collect the generated particles at the source, and avoid deposits in the surrounding area.

• Use suitable accessories for special work (see Chapter 11.), thus fewer particles enter the environment in an uncontrolled manner.

• Use a suitable extraction unit.

Reduce dust exposure with the following measures:

• Do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits.
• Use an extraction unit and/or air purifiers
• Ensure good ventilation of the workplace and keep clean using a vacuum cleaner Sweeping or blowing stirs up dust
• Vacuum or wash the protective clothing Do not blow, beat or brush

Initial Operation

Before plugging in, check that the rated mains voltage and mains frequency, as stated on the rating label, match your power supply.
Always install an RCD with a max. the trip current of 30 mA upstream.

Attaching the additional handle
Always work with the additional handle attached (10)! Attach the additional handle on the left or right of the machine and secure it. Attach the additional handle to the side facing away from the sanding belt (6).

Turning the sanding head (8) to the operating position
Note: To turn the clamping lever (9) the position of the lever must be changed if necessary. The position can be changed without clamping. For this purpose, raise the lever, turn it and then lower the lever again.

• Release the clamping lever (9).
• If necessary and depending on the working conditions, turn the sanding head (8). The sanding head must be positioned in the permitted working area as shown (see illustration A, page 2).
• Firmly tighten the clamping lever (9).
• The clamping lever (9) is tongued. If you pull it out slightly, it can be turned on the hexagon underneath.

Each time before you start work, verify that the clamping lever (9) is sufficiently tightened to ensure that the sanding head (8) does not move. Otherwise, the sanding belt (6) may come in contact with the user. Loss of control can cause personal injury.

Use

On/Off switch, continuous activation

• Always guide the machine with both hands.
• Switch the machine on first before mounting it on the workpiece.
• The machine must not be allowed to draw in additional dust and shavings. When switching the machine on and off, keep it away from dust deposits.
• After switching off the machine, only place it down when the motor has come to a standstill.
• Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut.
• In continuous operation, the machine continues running if it is forced out of your hands. Therefore, always hold the machine using the handles provided, stand in a safe position and concentrate.
