lead to re and electric shock. Damaging a
gas line can lead to explosion. Penetrating a
water line causes property damage.
2. Switch off the power tool immediately
when the tool inserts jams. Be prepared
for high reaction torque that can cause
kickback. The tool insert jams when:
--the power tool is subject to overload or
--it becomes wedged in the workpiece.
3. Hold the power tool only by the insulated
grpping surfaces, when performing an
operation where the cutting tool may run
into hidden wiring. Contact with a “live”
wire will make exposed metal parts of the
tool “live” and shock the operator.
4. Hold the power tool with a rm grip. High
reaction torque can briey occur while driving
in and loosening screws.
5. Secure the workpiece. A workpiece
clamped with clamping devices or in a vice is
held more secure than by hand.
6. Keep your workplace clean. Blends of
materials are particularly dangerous. Dust
from light alloys can burn or explode.
7. Always wait until the power tool has come to
