5.2 Correct use

The drill stand is for use with the DD EC-1 diamond cor-
ing machine.
It permits holes to be drilled at right angles to the work-
ing surface.
Do not use the drill stand with other drilling machines.
5.3 Take the necessary precautions to make the work-
place safe
● Ensure that the working area is well lit.
● Ensure that the working area is well ventilated.
● Objects which could cause injury should be removed
from the working area.
● When drilling holes through ceilings or floors from
above, secure the area below as the core may fall out,
presenting a risk of injury or damage.
● When working, keep other persons, particularly chil-
dren, outside the range of the equipment.
● Avoid unfavorable body positions.
● Always concentrate on the job you are doing. Pro-
ceed carefully and do not use the equipment if your full
attention is not on the job.
● Use a PRCD residual current device (ground fault
interrupter switch).
● Wear non-slip safety boots or shoes and always work
from a secure stance.
● Wear suitable working clothing.
● Wear protective gloves.
● Do not wear loose clothing, loose long hair or jewel-
ry as it can become caught up in moving parts.
● Wear goggles.
● To avoid tripping while working, always guide the sup-
ply cord, extension cord and water hose away to the rear
of the electric tool.
● 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 were work-
ing beforehand (e.g. using a metal detector). External
metal parts of the equipment may become live, for exam-
ple, when an electric cable is drilled into inadvertently.
● Avoid contact between your body and earthed / ground-
ed objects such as pipes or radiators.

5.4 General safety precautions

● Operate the equipment only as directed and only when
it is in faultless condition.
● Use only the original accessories or additional equip-
ment listed in the operating instructions. Use of other
items or accessories may present a risk of personal
injury.
