to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
Always wait until the power tool has come to a com-
u
plete stop before placing it down. The application tool
can jam and cause you to lose control of the power tool.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Do not touch any application tools or adjacent housing
u
components shortly after operation. These can become
very hot during operation and cause burns.
The application tool may jam during drilling. Make
u
sure you have a stable footing and hold the power tool
firmly with both hands. Otherwise you could lose con-
trol of the power tool.
Take care when carrying out demolition work using
u
the chisel. Falling fragments of the demolition material
could injure you or any bystanders.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
