5. Safety precautions

-WARNING- The following basic safety precautions
must always be observed when using electric machines
in order to avoid the risk of electric shock, injury or fire.
Read all of these instructions before using this machine
and keep this list of safety precautions for future ref-
erence.
5.1 The necessary safety precautions at the work-
place
Approval must be obtained from the site engineer or
●
architect prior to beginning drilling work. Drilling
work on buildings and other structures may influ-
ence the statics of the structure, especially when
steel reinforcing bars or load-bearing components
are cut through.
Ensure that the workplace is well lit.
●
Ensure that the workplace is well ventilated.
●
Keep the workplace tidy. Objects which could cause
●
injury should be removed from the working area.
Untidiness at the workplace can lead to accidents.
When drilling through-holes, the area below the ceil-
●
ing, floor or behind the wall where the drilling is tak-
ing place must be secured as the drilled-out core
may fall out.
Use clamps or a vice to secure the workpiece. The
●
workpiece is thus held more securely than by hand
and both hands remain free to operate the machine.
Use protective equipment. Wear eye protection.
●
Wear breathing protection if the work creates dust.
●
Wear suitable working clothing. Do not wear loose
●
clothing, loose long hair or jewelry as it can become
caught up in moving parts. Wear suitable headgear
if you have long hair.
It is recommended that rubber gloves and non-slip
●
shoes are worn when working outdoors.
Keep children and other persons away from the work-
●
ing area.
Do not allow other persons to tamper with the machine
●
or the supply cord.
Avoid unfavorable body positions. Work from a secure
●
stance and stay in balance at all times.
To avoid tripping and falling when working, always
●
lead the supply cord, extension cord and water hose
away to the rear.
Keep the supply cord, extension cord, water hose
●
and vacuum hose away form rotating parts of the
machine.
-WARNING- Before beginning drilling, check that
●
there are no live electric cables located in the area
where the hole is to be made.
Concealed electric cables or gas and water pipes pre-
●
sent a serious hazard if damaged while you are work-

ing. Accordingly, check the area in which you are
working beforehand (e.g. using a metal detector).
External metal parts of the machine may become
live, for example, when an electric cable is drilled
into inadvertently.
Do not work from a ladder.

5.2 General safety precautions

Use the right machine for the job. Do not use the
●
machine for purposes for which it was not intend-
ed. Use the machine only as directed and when it is
in faultless condition.
Use only the original accessories or ancillary equip-
●
ment listed in the operating instructions. Use of oth-
er insert tools or accessories may present a risk of
personal injury.
Take the influences of the surrounding area into
●
account. Do not expose the machine to rain or snow
and do not use it in damp or wet conditions. Do not
use the machine where there is a risk of fire or explo-
sion.
Keep the grips dry, clean and free from oil and grease.
●
Do not overload the machine. It will work more effi-
●
ciently and more safely within its intended perfor-
mance range. The side handle must be fitted for all
types of work.
Never leave the machine unattended.
●
When not in use, the machine must be stored in a
●
dry place, locked up or out of reach of children.
Avoid unintentional starting. Check that the on / off
●
switch is in the "off" position before plugging the
supply cord into the electric socket.
Unplug the machine from the electric supply when
●
it is not in use, during pauses between work, before
maintenance and when changing core bits.
Check the PRCD each time before use.
●
Take care of your core bits. You will be able to work
●
more efficiently and more safely if the core bits are
kept sharp and clean.
Check the machine for possible damage. Protective
●
devices and any parts that may have suffered slight
damage should be checked for correct operation and
functionality before further use. Check that moving
parts function correctly without sticking and that no
parts are damaged. All parts must be fitted correct-
ly and fulfill all conditions necessary for correct oper-
ation of the machine. Damaged safety devices or oth-
er damaged parts must be replaced or repaired prop-
erly by an authorized repair workshop unless other-
wise indicated in the operating instructions.
Avoid skin contact with drilling slurry.
●
Wear respiratory protection when the work creates
●
dust, e.g. during dry drilling. Connect a vacuum clean-
