4) Use and handling of the electric tool
a) Do not overload the device. Use the appropriate electric tool for your work. With the appropriate elec-
tric tool, you work better and saver in the declared range of performance.
b) Do not use an electric tool whose switch is damaged. An electric tool which can not be switched on and
off is dangerous and has to be repaired.
c) Disconnect the plug from the socket and/or remove the battery before carrying out instrument set-
tings, exchanging accessories or put the device aside. This safety measure avoids the unintended start
of the electric tool.
d) Keep unused electric tools out of reach of children. Do not allow persons to use the device who are
not familiar with it or have not read these instructions. Electric tools are dangerous if they are used by
inexperienced persons.
e) Maintain electric tools with care. Check if movable parts function correctly and do not jam, if parts
are broken or damaged in that way, that the function of the electric tool affected. Have damaged
parts repaired before using the device. Many accidents originate from bad maintained electric tools.
f) Keep the cutting tool sharp and clean. Carefully maintained cutting tools with sharp edges do jam less
and are easier to guide.
g) Use electric tool, accessory, operation tools, etc. according to these instructions. Thereby consider
the conditions of employment and the work to be done. The use of electric tools for others than the
intended task can result in dangerous situations.
h) Keep handles and grip surfaces dry, clean and free of oil and fat. Slippery handles and grip surfaces
do not allow a safe use and control of the electric power tool in unforeseen situations.
5) Service
a) Have your tool only repaired by qualified personnel and only with original spare parts. Thus it is
assured that the safety of the electric tool is being obtained.
6) Safety precautions for drilling machines
a) When performing drilling that requires the use of water, route the water away from the operator's
work area or use a liquid collection device. Such precautionary measures keep the operator's work area
dry and reduce the risk of electrical shock.
b) Operate power tool by insulated grasping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live" and could give the operator an electric shock.
c) Wear hearing protection while using drilling machines. The effect of noise can cause hearing loss.
d) If the cutting tool blocks, stop the feed and switch off the electric power tool. Check the reason of
blocking and remove the cause for blocking cutting tools.
e) If you want to switch on a diamond core drill whose drill bit sticks in the workpiece, check if the
cutting tool can revolve freely before switching on. If the cutting tool is clamped, it possibly will not turn,
may cause an overstress of the tool or cause the diamond core drill to come loose from the workpiece.
f) If attaching the drill stand at the workpiece by means of dowels or screws, make sure that the used
anchorage is able to hold the machine during operation securely. If the workpiece is not resistant or
porose the dowel can be removed whereby the drill stand separates from the workpiece.
g) When fastening the drill stand on the workpiece by means of vacuum pump make sure that the
surface is smooth, clean and non-porous. Do not mount the drill to laminated surfaces such as on tiles
and coatings of composites. If the surface of the workpiece is not smooth, flat or sufficiently secured, the
vacuum plate can loosen from the workpiece.
h) Make sure that the vacuum power is sufficiently safe before drilling. If there is insufficient vacuum
power the vacuum plate can loosen from the workpiece.
i) Never perform overhead drilling when the machine is attached only by vacuum plate. In case of loss
of the vacuum, the vacuum plate detaches from the workpiece.
j) Make sure that persons and working area on the opposite site are protected if you drill through walls
and ceilings. The drill bit can overlap the borehole and the drill core can fall out of the drill bit on the other
side.
k) Do not use this tool for overhead drilling with water supply. Water entering the power tool will increase
the risk of electric shock.
l) Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility
company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas
line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.
