- Only qualified, trained operators are authorised to
install, adjust or use the air tool.
- The air tool must not be modified. Any modifica-
tions may reduce the efficiency of the safety
measures and increase risks for the operator.
- Never use air tools that have been damaged. Look
after your air tools carefully. Regularly check that
all moving parts are functioning correctly and do
not jam. Also ensure that no parts are broken or
damaged to an extent that they affect the opera-
tion of the air tool. Check that all signs and labels
are legible and intelligible. Have damaged parts
repaired or replaced before using the device.

air tools.
4. Special Safety Instructions
4.1 Risks associated with ejected parts
- Disconnect the air tool from the compressed air
supply before replacing the mounted tool or
accessory parts, and also before carrying out
repairs or settings.
- If either the workpiece, accessory parts or the air
tool breaks, parts may be ejected at high speed.
- While operating, maintaining or repairing the air
tool, or replacing accessory parts, you must
always wear impact-resistant safety goggles. The
degree of protection required for each individual
task must be evaluated separately in each case.
- Ensure that the workpiece is securely attached.
- You must ensure that the abrasive is securely
mounted on the grinder for abrasives.
- Check that the maximum operating speed of the
abrasive (calculated in revolutions per minute)
equals or exceeds the rated speed of the spindle.
Furthermore, you must not attach brushes to the
machine if their rotational speed is higher than the
maximum permissible speed for brushes;
- Ensure that the safety guard is fitted, in good
condition and properly secured. It must be
checked regularly.
- Regular checks must be carried out to verify that
the air tool's rotational speed does not exceed the
speed specified on the tool. These speed checks
must be conducted when no mounted tool is fitted.
Metabo's Service Centre can perform these
checks for you.
- Ensure that any sparks or fragments emitted
during operation do not pose a risk.
- Disconnect the air tool from the compressed air
supply before replacing the mounted tool or
accessory parts, and also before carrying out
maintenance, settings or cleaning.
- Check that the clamping flanges comply with the
manufacturer's instructions. Also check that they
are in good condition, for example, that they are
even and do not have cracks;
- You must check whether the spindle and spindle
thread are damaged or worn.
