The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Values can vary depending on the product and are subject to application and environmental conditions. For further information www.bosch- professional.com/wac.

Noise/Vibration Information

Noise emission values are determined according to EN 60745-2-23.
Typically, the A-weighted noise level of the power tool is: Sound pressure level 80 dB(A); and Sound power level 91 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!

Total vibration values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-23:
Surface grinding (roughing with a grinding tool diameter of 25 mm): ah = 6 m/s2, K = 1.5 m/s2
Surface grinding (roughing with a grinding tool diameter of 50 mm): ah = 21 m/s2, K = 1.5 m/s2
The vibration level given in these instructions has been measured in accordance with a standardized measuring procedure and may be used to compare power tools. It can also be used for a preliminary estimation of exposure to vibra-tion.
The stated vibration level applies to the main applications of the power tool. However, if the power tool is used for different applications, with different application tools, or poorly maintained, the vibration level may differ. This can significantly increase the exposure to vibration over the total working period.
To estimate the exposure to vibration 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 can significantly reduce the exposure to vibration 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 the hands warm, and organizing workflows correctly.

Fitting

Pull the plug out of the socket before carrying out any work on the power tool.

Fitting Abrasive Tools Using an Open-Ended Spanner and Spindle Lock (see Figure A)

Only use open-ended spanners that are suitable and undamaged (see “Technical Data”).
Clean the grinding spindle (3) and all the parts to be fitted.
Press the spindle lock (11) and turn the clamping nut (2) by hand until locked.
Press and hold the spindle lock and loosen the clamping nut (2) with the open-ended spanner (9) by turning it anticlockwise.
Insert the straight shank of the grinding tool all the way into the collet (1).
Press the spindle lock (11) and tighten the application tool by placing the open-ended spanner (9) on the spanner flat and turning it clockwise.
The grinding tools must run completely concentrically. Do not continue to use damaged grinding tools that are out of balance. If the grinding tools are out of balance, they should be replaced.
Do not, under any circumstances, tighten the collet with the clamping nut until a grinding tool has been fitted. The collet may otherwise become damaged.
Only use mounted points with an appropriate shank diameter. A mounting point with a shank diameter that does not correspond to the tool holder of the power tool (see “Technical data”) cannot be held properly and will damage the collet chuck.
The application tool must be clamped at least 10 mm.
The inner shank dimension L0 can be used to calculate the maximum permitted speed of the application tool from the specifications provided by the manufacturer of the application tool. It must not be less than the maximum speed of the power tool.

Fitting Abrasive Tools Using Two Open-Ended Spanners (see Figure B)

Only use open-ended spanners that are suitable and undamaged (see “Technical Data”).
Clean the grinding spindle (3) and all the parts to be fitted.
Use an open-ended spanner (8) on the spanner flat of the grinder spindle (3) to hold it in place.
Loosen the clamping nut (2) by placing an open-ended
spanner (9) on the spanner flat and turning it counterclockwise.
Insert the straight shank of the grinding tool all the way into the collet (1).
Hold the grinding spindle (3) with the open-ended spanner (8) and tighten the application tool by placing the open-ended spanner (9) on the spanner flat and turning it clockwise.
The grinding tools must run completely concentrically. Do not continue to use damaged grinding tools that are out of balance. If the grinding tools are out of balance, they should be replaced.
Do not, under any circumstances, tighten the collet with the clamping nut until a grinding tool has been fitted. The collet may otherwise become damaged.
Only use mounted points with an appropriate shank diameter. A mounting point with a shank diameter that does not correspond to the tool holder of the power tool (see “Technical data”) cannot be held properly and will damage the collet chuck.
The application tool must be clamped at least 10 mm.
The inner shank dimension L0 can be used to calculate the maximum permitted speed of the application tool from the specifications provided by the manufacturer of the application tool. It must not be less than the maximum speed of the power tool.

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some wood types, minerals, and metal can be harmful to one’s health. Touching or breathing in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
Provide for good ventilation of the working place.
It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the materials to be worked.
Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

Starting operation

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.
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. Power tools marked with 230 V can also be operated with 220 V.
Check whether there is visible damage to the collet (1) and clamping nut (2) before each use.

Switching On and Off

To start the power tool, slide the on/off switch (5) forwards.
To lock the on/off switch (5) in position, push the on/off switch (5) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (5); or, if the switch is locked, briefly push the on/off switch (5) backward and down and then release it.

Constant Electronic control

The Constant Electronic keeps the speed at no load and under load virtually consistent, guaranteeing uniform performance.

Speed preselection

You can preselect the required speed using the speed preselection thumbwheel (6), even during operation.
The required speed depends on the material being worked and the diameter of the application tool. Observe the maximal allowable speed of the application tool.

Thumbwheel position No-load speed (min-1)

1	7000
2	9500
3	15000
4	19000
5	25000
6	33000

Kickback Stop

If there is a sudden kickback in the power tool, e.g. jamming when carving, the power supply to the motor will be interrupted electronically.
To restart the tool, set the on/off switch (5) to the off position and then switch the power tool on again.

Restart Protection

The restart protection feature prevents the power tool from uncontrolled starting after the power supply has been interrupted.
To restart the tool, set the on/off switch (5) to the off position and then switch the power tool on again.
Note: Rapidly switching the power tool off and on again may trigger restart protection, meaning the power tool may not start up even if the on/off switch (5) is pressed. Set the on/off switch (5) to the off position and then switch thepower tool on again.

Soft start

The electronic soft start limits the torque when the power tool is switched on and increases the service life of the motor.

Practical advice

Pull the plug out of the socket before carrying out any work on the power tool.
Protect the grinding tools against impact.
Do not load the power tool so heavily that it comes to a stop.
If the power tool has been subjected to a heavy load, continue to run it at no load for several minutes to cool down the accessory.
Grinding tools can become very hot while working. Do not touch them until they have cooled down.
Move the grinding tool evenly back and forth with light pressure to achieve an optimum work result. Pressure that is too strong reduces the performance capability of the power tool and causes the grinding tool to wear more quickly.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any work on the power tool.
To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.
In extreme conditions, always use a dust extractor if possible. Blow out ventilation slots frequently and install a residual current device (RCD) upstream.
When machining metals, conductive dust can settle inside the power tool, which can affect its protective insulation.
Store and handle the accessories carefully.
In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service center that is authorized to repair Bosch power tools.
