Special safety instructions.
Secure the power tool with the clamping strap
supplied if there is danger of it falling, especially
for work carried out at a height, on vertical con-
struction elements or above the head.
If there is a
power cut, or the mains plug is pulled out, the
magnetic holding power is not maintained.
If work is carried out on vertical construction ele-
ments or above the head, prevent any fluid (cool-
ant) from penetrating the power tool.
There is
danger of an electric shock. Work here using a
coolant spray.
Avoid touching the drilled core that is automati-
cally ejected by the centering pin when the work-
ing procedure is finished.
Contact with the core
when it is hot, or if it falls, can cause personal
injuries.
Operate the power tool only from earthing contact
sockets that comply with the specifications. Do
not use any connection cables that are damaged;
use extension cables with an earthing contact that
are checked at regular intervals.
A earth conduc-
tor without continuity can cause an electric
shock.
Do not rivet or screw any name-plates or signs
onto the power tool.
If the insulation is damaged,
protection against an electric shock will be inef-
fective. Adhesive labels are recommended.
Wear personal protective equipment. Depending
on the application, use a face shield, safety gog-
gles or safety glasses. Wear ear protection.
The
safety glasses must be capable of protecting
against flying particles generated by the various
different operations. Prolonged exposure to
high intensity noise may cause loss of hearing.
Do not use accessories which are not specifically
designed and recommended by the power tool
manufacturer.
Safe operation is not ensured
merely because an accessory fits your power
tool.
Clean the ventilation openings on the power tool at
regular intervals. The motor blower draws dust
into the housing.
An excessive accumulation of
metallic dust can cause an electrical hazard.
The guard protecting against chippings and acci-
dental contact must always be mounted during
operation.
Hot, sharp chippings can cause per-
sonal injuries.
