Personal Protective Equipment; Before Use - Hilti DD-CR1 Mode D'emploi

● Keep the grips clean, dry and free of oil and grease.
● Do not overload the equipment. It will operate more
efficiently and more safely within the performance range
for which it is designed.
● Never leave the equipment unsupervised.
● Switch the diamond coring machine on only after
bringing it into position at the workpiece where the hole
is to be drilled.
● When not in use, the drill stand must be kept in a high,
dry place or locked away where it is out of reach of chil-
dren.
● Avoid unintentional starting. Check that the ON / OFF
switch is in the OFF position before plugging the supply
cord into the mains socket.
● Always unplug the supply cord when the diamond
coring machine is not in use, e.g. during pauses between
work, before carrying out care and maintenance and
before changing core bits.
● Switch the diamond coring machine off before trans-
porting it.
● Ensure that the electric tool is switched off (remove
the switch lock insert) before switching on at the PRCD
(ground fault interrupter).
● Test the PRCD each time before use.
● Check that all moving parts are undamaged and that
they function properly without sticking. All parts must
be fitted correctly and fulfil all of the conditions neces-
sary to ensure faultless operation.
● Observe the instructions on care and maintenance
(Section 8).
● If necessary, have the drill stand repaired at a Hilti ser-
vice center in order to ensure that original Hilti spare
parts are used. Failure to observe this point may pre-
sent a risk of injury to the user.
