Special Safety Instructions

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

Hold the power tool by the insulated gripping surfaces because the abrasive belt may contact its own cord.
Damage to a “live” wire may energize metal parts of the power tool and cause an electric shock. When sanding metals: Connect the machine to a suitable extraction device after removing wood dust (from the machine, hose, and extraction device) – the risk of dust explosion and fire through sparks created when sanding metal! 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). Dust from materials such as paint containing lead, some wood species, minerals, and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists.
– Use a dust extractor or the dust bag where possible.
– To achieve a high level of dust collection, use a suitable Metabo vacuum cleaner together with this tool.
– The workplace must be well ventilated.
– The use of a dust mask of filter class P2 is recommended. Follow national requirements for the materials you want to work with. Materials that generate dust or vapors that may be harmful to health must not be processed. Wear ear protectors. Exposure to noise can cause loss of hearing. 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 lead to injuries. Remove chips and similar material only with the machine at standstill. Pull the plug out of the plug socket before any adjustments or servicing are performed. Avoid inadvertent starts by always unlocking the switch when the plug is removed from the mains socket or in case of a power cut.

Commissioning

Before plugging in, check to see that the rated mains voltage and mains frequency, as specified on the rating label, match your power supply.

Additional handle
The additional handle (9) can be fitted in 2 positions (at different heights).
– Unscrew the screw (10) with hexagon spanner (7) and remove.
– Shift the additional handle. The 2nd position is reached when the screw can be pushed in.
– Insert screw with hexagon spanner and tighten.

Use

7.1 Dust extraction
Dust bag: Mount the dust bag (2) with its connector on the machine’s ejection nozzle (3) and turn counterclockwise as far as the stop (bayonet catch). To optimize the extraction performance, empty the dust bag in good time. The dust bag should not be filled with sanding dust beyond 1/3 of its capacity.

** When emptying the dust bag, ensure that sanding dust cannot penetrate your body or harm, other persons.
Dust extraction with a dust extractor:** During long periods of sanding wood and – in commercial applications – materials where the dust that is harmful to health is created during processing (e.g. beech and oak, leaded coatings, metals), the belt sander must be connected to an extraction device suitable for this purpose. Comment: In Germany, extraction devices certified according to TRGS 533 (Technical Rules on Dangerous Substances) must be used to extract wood dust. For other materials, commercial users must clarify the special requirements with the responsible employer’s liability insurance association.

– Remove the dust bag (2).
(Bayonet catch! Turn the dust bag clockwise and remove it from the machine’s ejection nozzle (3) together with its connector.)
– Fit adapter (8) onto ejection nozzle (3).
– Fit the hose on the adapter (8). (Fitting requires exertion of force. Use a hose with connector dia. 35 mm, e.g. the hose from a Metabo universal vacuum cleaner or the hose an
another vacuum cleaner suitable for this purpose.)

7.2 On/Off switch, continuous activation
Note: Switch the machine on first before mounting it on the workpiece.

To start the machine, press the trigger switch (6).
For continuous operation, the trigger switch can be locked using the lock button (5). To stop the machine, press the trigger switch (6) again.
**** In continuous operation, the machine continues running if it is forced out of your hands. Therefore, always hold the machine with both hands using the handles provided, stand in a safe position, and concentrate.

7.3 Setting belt speed
Set the belt speed at the adjusting wheel (4). This is also possible during operation. The required belt speed depends on the material and the working conditions and can be determined through practical tests.
If – as a result of overloading – the motor speed (and thus the belt speed) decreases significantly during work, the adjusting wheel (4) must be set to a higher value (than the previous one).

7.4 Adjusting belt run
**** Use the rotary knob (1) to adjust the sanding belt – with the machine running – so that it runs centrally on the sanding belt roller.

7.5 Sanding procedure
Switch the machine on first before mounting it on the workpiece. Mount the belt sander on the material, holding it with both hands – with the sanding belt parallel to the workpiece surface. Keep the machine in constant motion because otherwise recesses could be produced in the material. It is not necessary to exert additional pressure on the machine when sanding. It is sufficient to guide it and allow its well-distributed weight to run it.

7.6 Sanding belt replacement
**** Pull the mains plug out of the socket.
Swivel out lever (12) as far as it will go. This relieves sanding belt tension and it can now be removed from the rollers. For sanding belts, see Accessories chapter 10. Place the new sanding belt on the rollers such that its direction of circulation (arrows on the inside of the sanding belt) matches the arrow (11) on the machine housing. To tension, the sanding belt, press the lever (12) back into its initial position.

7.7 Stationary use of machine
Fitting stand
(equipment-dependent)
Secure the machine safely on the stand (13) before using it. Slipping of the machine on the stand can result in loss of control.
Place the stand (13) on a firm, flat, horizontal surface. Safe, steady work cannot be guaranteed if the stand slides or wobbles.
– Fit the additional handle (9) in the bottom position.
– Hook in the stand (13) as shown in the illustration.
– Then screw the wing screw (14) of the stand into the machine housing and tighten.
– Place the machine on the stand (the sanding belt faces upwards).
– The stand can be secured to the workbench with two collets 6.27107 (see Accessories chapter 10).

Fitting parallel guide (equipment-dependent)
Once the machine has been set up in this manner, the parallel guide (17) can be fitted. Secure the parallel guide with the wing screw (19) to the machine housing. After releasing the wing screw (15), the plate (16) of the parallel guide can be shifted. For sanding inclined surfaces, the plate (16) of the parallel guide can be inclined by up to 45° after the wing nut (18) is released.

Cleaning, Maintenance

To optimize the extraction performance, empty the dust bag in good time. The dust bag should not be filled with sanding dust beyond 1/3 of its capacity. When emptying the dust bag, ensure that sanding dust cannot penetrate your body or harm, other persons. Clean the machine regularly. This includes vacuum cleaning the ventilation louvers on the motor.

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. Use a suitable sanding disc to achieve the best
possible work results:
– Removal of old paint layers, coarse sanding work on wood: ………………….. P 40
– Finishing of wood, sanding steel: ……………………………..P 60, P 80
– Sanding of veneered surfaces: .. P 100 – P 180
– Very fine sanding of wood and plastics (finishing).
Pre-sanding for subsequent burnishing work (metal)……………..P 240, P 320

Vibration total value (vector sum of three directions) determined in accordance with EN 60745:
ah = Vibration emission value (sanding surfaces)
Kh = Uncertainty (vibration)

The vibration emission level given in this information sheet has been measured in accordance with a standardized test given in EN 60745 and may be used to compare one tool with another. It is also suitable for a provisional estimate of the vibratory load.
The specified vibration level applies to the main applications of the power tool. However, if the tool is used for different applications, with different accessories, or poorly maintained, the vibration emission may differ. This can considerably increase the vibratory load over the entire working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintaining the tool and the accessories, keeping the hands warm, and organization of work patterns.

Typical A-effective perceived sound levels:
LpA = Sound pressure level
LWA = Acoustic power level
