When using carbide burrs and brushes, avoid exceeding the permissible load and circumferential speed in order to
avoid danger to persons or damage to property.
Complete a 30-second test run before starting to use the unit.
Only process a workpiece with the tool, never with other parts of the rotating spindle. Damaged or incorrectly fixed
grinding tools can cause extreme vibration.
It is imperative that you check the tool for any damage after it has been dropped.
Before starting work, and after each interruption, check the machine and tool for signs of damage.
Check the tool is clamped securely in the collet chuck of the handpiece because the tool could become loose and
fly out of the collet chuck!
Only use accessories specially designed and recommended by the manufacturer for this power tool!
Check that the shaft is correctly seated on the drive unit and the handpiece. Incorrect installation can result in
damage to the drive train!
Secure the workpiece in a clamping device or a vice!
Avoid contact with power sources! The device is not insulated against contact with live parts.
Only use the drive unit with an undamaged flexible shaft! Check the components, mains cable and connections for
damages before starting work!
Before changing the tool and during maintenance work, always disconnect the machine from the mains to prevent
uncontrolled startup!
The connecting plug must not be modified. Do not use any plug adapters!
Never remove the handpiece without first turning off the machine! Notice: The tool runs on after being switched off.
Only set the unit down after it has come to a stop!
The electric motor needs longer to stop if there is a power failure.
When setting up the machine, make sure that the machine is standing securely and observe the range of the
flexible shaft!
Do not use insert tools that require liquid coolant!
4.6 Conduct at the Workplace
Keep your place of work tidy.
Work carefully! Do not use the unit if you are tired or under the influence of alcohol, drugs or medicines!
Sparks are caused by grinding and brushing. Remove any combustible objects, substances and materials! Ensure
adequate ventilation!
Always concentrate on the job at hand and keep others away from the work area!
Keep your tools in a safe, secure place and maintain them carefully!
Repair work may only be carried out by authorised specialist personnel.
Use a dust extraction system.
Ensure good lighting and ventilation at the workplace.
Wear a respirator with filter class P2, gloves and protective clothing.
4.7 Behaviour in case of an Emergency
In an emergency, press the "STOP" button.
CAUTION
– Machine continues running!
If you pull out the mains plug, the electric motor cannot be braked by the frequency inverter!
The electric motor needs longer to come to a stop.
4.8 Behaviour in case of Accidents
Inform yourself as a matter of routine at regular intervals regarding possibilities for first-aid.
Immediately inform your superior
– after injured persons are provided with first-aid – if persons are involved in
accidents or if there is damage to units or buildings.
To enable rescue vehicles to provide efficient help, indicate the level of injury and damage to property.
