Unplug the tool and make sure that the switch is off if the tool is not
under supervision, e.g. during preparation and take-down works, at
power failures, for insertion or mounting accessories.
Unplug the tool if it stops for any reason. So you avoid sudden starts in
unattended condition.
Don't use the machine if a part of the housing is damaged or in case of
damages on the switch, the cable or plug.
Always lead the mains and extension cables as well as the dedusting
hose from the tool to the back.
Electrical tools have to be inspected visually by a specialist in regular
intervals.
On using the tool, in no case cooling water may seep into the motor or
the electric components.
If water comes out of the drainage hole at the gear neck, stop your
work and have the tool repaired by an authorised service centre.
Perform overhead drilling only with suitable protective appliances
(water catcher).
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 reducethe risk of electrical shock.
When the bit is jammed, stop applying downward pressure and
turn off the tool. Investigate and take corrective actions to eliminate
the cause of the bit jamming.
When restarting a diamond drill in the workpiece check that the bit
rotates freely before starting. If the bit is jammed, it may not start,
may overload the tool, or may cause the diamond drill to release from
the workpiece.
Always wait until the machine has come to a complete stop before
placing it down. The tool insert can jam and lead to loss of control
over the power tool.
Keep the handles dry, clean and free of oil and grease.
Do not touch rotating parts.
Persons under 16 years are not allowed to use the tool.
During use, the user and other persons standing nearby have to wear
suitable goggles, helmets, ear protectors, dust mask, protective cloves
and boots.
During manual operation, always hold the tool with both hands
and be fall-safe. Consider the tool's reaction torque in case of
blocking.
When securing the drill stand with anchors and fasteners to the
workpiece, ensure that the anchoring used is capable of holding
and restraining the machine during use. If the workpiece is weak or
porous, the anchor may pull out causing the drill stand to release from
the workpiece.
