Observe the following safety precautions to avoid injuring
yourself and/or others:
►Operate the machine only with the protective equipment
stipulated in these operating instructions (see section
Personal protective equipment).
►Do not wear protective gloves when the machine is running.
A glove can be caught by the drilling machine and torn off
the hand. Risk of losing one or more ngers.
►Remove loose jewellery before beginning work. Wear a hair
net if you have long hair.
►Always switch off the machine before changing tools,
performing maintenance or cleaning. Wait until the machine
has come to a complete standstill.
►Always remove the plug from the mains socket before
changing tools, cleaning or performing maintenance, in
order to avoid unintentional starting of the machine.
►Do not put your hand into the machine while it is in
operation. Remove shavings only when the machine is at a
standstill. Wear protective gloves when removing swarf.
►When working on scaffolding, the operator must be secured
with a safety belt as the machine can oscillate dangerously
in the event of interruption to the power supply.
►Check for secure clamping of the electromagnets on the
substrate before every use (see section Preparing).
►Secure the machine with the safety chain supplied when
working from an inclined or vertical position or during
overhead work. The machine could fall down if the magnet is
loosened or the power fails.
►Check that the tool is tightened securely before using (see
section Inserting the tool).
►Do not allow the connecting cable to hang over edges
(danger of tripping).

liquids.
►Do not pull the connecting lead across sharp edges or hot
surfaces.
