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 instructions 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.

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. Pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning.
Secure the workpiece against slipping, e.g. with the help of clamping devices.
Wear ear protectors when working for long periods of time. High noise levels over a prolonged period of time may affect your hearing.
Hold the machine from the handles provided.
Reducing dust exposure:
Some of the dust created using this power tool may contain substances known to cause cancer, allergic reactions, respiratory disease, birth defects or other reproductive harm. Some examples of these substances are: lead (from lead- based paints), crystalline silica (from bricks cement, etc.), additives for wood treatment (chromate, wood preservative), some types of wood (like oak and beech dust), metals, asbestos.
The risk from exposure to such substances will depend on how long the user or nearby persons are being exposed. Do not let particles enter the body. To reduce exposure to these substances: work in a well-ventilated area and wear protective equipment, such as dust masks that are specially designed to filter out microscopic 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 only suitable accessories. In this way, 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 it clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
Vacuum or wash protective clothing. Do not blow, beat or brush.

Commissioning

Before plugging in, check to see that the rated mains voltage and mains frequency, as stated on the rating label, match your power supply.
Always install an RCD with a maximum trip current of 30 mA upstream.
6.1 Additional handle (removable)
If necessary, you can unscrew the additional handle (3) (right-hand thread).
6.2 Installation of the sanding disc
Simple attachment and removal thanks to the velcro-type fastening.
Simply press on the sanding disc such that the holes in the sanding disc (1) are aligned with the support plate (2).

Use

7.1 Duo oscillating circuit setting (only with SXE 450 TurboTec)

You can choose between two oscillating frequency settings:

• Oscillating circuit high setting (6.2 mm): coarse sanding with high material removal rate
• Oscillating circuit low setting (2.8 mm): fine sanding, polishing

Changing oscillating circuit:
– Disconnect the mains plug!
– Press in the locking button (8) and hold in place.
– Rotate support plate (2) in a counter-clockwise direction until you can hear it engage.
– Continue holding in the button.
– Continue turning the support plate half a revolution to the next snap-in point.
– Release the locking button.
7.2 On/Off switch, continuous activation
To start the machine, press the trigger switch (7).
For continuous operation, the trigger switch can be locked using the lock button (6). To stop the machine, press the trigger switch (7) again.
7.3 Setting oscillating frequency
When the TurboBoost switch (5) is switched off, the oscillating speed can be set at the setting wheel (4). This is also possible during operation.
Recommended oscillating frequency settings:
Plastic materials . . . . . . . . . . . . . . . . . . . . .1-2Metal, Plexiglas® , old coats of paint . . . . .3-4
Coarse and fine sanding, polishing, wood 5
The best way to determine the ideal setting is through a practical trial.
7.4 TurboBoost switch
Actuate the TurboBoost switch (5) during the operation to switch on additional power reserves for maximum material removal rate.
7.5 Dust extraction
To optimize the dust extraction performance, fit the sanding disc such that the holes on the sanding disc (1) are aligned with the support plate (2).
Note: We recommend connecting a suitable extraction device when sanding abrasive material (e.g. plaster, etc.).
Own extraction units:
Fit the dust bag (12) to the ejection nozzle (11). Pull the dust bag (12) backward to remove it.
Empty the dust bag (12) in good time to optimize dust extraction.
Third-party extraction units:
Connect a suitable extraction device to the ejection nozzle (11).

Cleaning, Maintenance

Emptying the dust bag: remove the closure band (13). Empty the dust bag (12), and clean it with an extraction device if necessary. Close the dust bag again with the closure band (13).
They clean the machine regularly, frequently, and thoroughly.
This includes vacuum cleaning the ventilation louvers on the motor.
Replacing a worn support plate
Note: If abrasive material (e.g. filled or painted surfaces, etc.) is being sanded, the support plate inevitably wears faster.
-Use the hexagon spanner (10) to unscrew the fixing screw (14) on the support plate.
– Remove support plate (2).
– For replacement support plates, refer to the Accessories chapter.
– Mount support plate (2) and rotate until it engages on carrier disc.
– Insert locking screw (14) again and tighten.
Replacing a support plate brake/braking ring
If the idle speed of the support plate increases in course of time, the braking ring (15) is worn and must be replaced.
Note: If abrasive material (e.g. filled or painted surfaces, etc.) is being sanded, the braking ring inevitably wears faster.
– Use the hexagon spanner (10) to unscrew the fixing screw (14) on the support plate.
– Remove support plate (2).
– Replace the old braking ring (15) with the new braking ring (see page 2), ensuring that the new braking ring is in the same position as the old braking ring. Ensure that the position of the marking on the braking ring is correct.
– For proper functioning, apply a thin layer of grease (see page 2) on the braking ring at its contact surface to the support plate.
– Mount support plate (2) and rotate until it engages on carrier disc.
– Insert locking screw (14) again and tighten.

Tips and Tricks

Do not press the device too firmly against the surface being sanded. This does not improve, but rather impairs, the sanding performance.
Empty the dust bag (12) in good time to optimize dust extraction.
Use a suitable sanding disc to achieve the best possible work results:
Removal of old paint layers = P 40
Pre-sanding of wood = P 60, P 80
Finishing of wood = P 100, P 120
Sanding of veneers, sealing primer, filler, paint = P 180, P 240, P 320, P 400
