Switch off the power tool immediately
when the tool insert jams. Be prepared for
high reaction torque that can cause kick-
back. The tool insert jams when:
— the power tool is subject to overload or
— it becomes wedged in the workpiece.
Hold the machine with a firm grip. High re-
action torque can briefly occur while driving
in and loosening screws.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
Always wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
Do not open the battery. Danger of short-
circuiting.
Protect the battery against heat, e. g.,
against continuous intense sunlight,
fire, water, and moisture. Danger of
explosion.
Use only original Bosch batteries with the
voltage listed on the nameplate of your
power tool. When using other batteries, e. g.
imitations, reconditioned batteries or other
brands, there is danger of injury as well as
property damage through exploding batter-
ies.
