Electrical Safety - Berner BHD-3-30 Handbuch

f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g ) Use the power tool, accessories and tool bits etc.,
in accordance with these instructions taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
5) Service
a ) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Additional Safety Instructions for
Rotary Hammers
• Wear ear protectors. Exposure to noise can cause
hearing loss.
• Use auxiliary handles supplied with the tool. Loss of
control can cause personal injury.
• Hold power tool by insulated gripping 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.
• Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss of control.
• Wear safety goggles or other eye protection. Hammering
operations cause chips to fly. Flying particles can cause
permanent eye damage. Wear a dust mask or respirator
for applications that generate dust. Ear protection may be
required for most applications.
• Keep a firm grip on the tool at all times. Do not attempt
to operate this tool without holding it with both hands. It
is recommended that the side handle be used at all times.
Operating this tool with one hand will result in loss of control.
Breaking through or encountering hard materials such as
re-bar may be hazardous as well. Tighten the side handle
securely before use.
• Do not operate this tool for long periods of time. Vibration
caused by hammer action may be harmful to your hands and
arms. Use gloves to provide extra cushion and limit exposure
by taking frequent rest periods.
• Do not recondition bits yourself. Chisel reconditioning should
be done by an authorized specialist. Improperly reconditioned
chisels could cause injury.
• Wear gloves when operating tool or changing bits. Accessible
metal parts on the tool and bits may get extremely hot
during operation. Small bits of broken material may damage
bare hands.
• Never lay the tool down until the bit has come to a complete
stop. Moving bits could cause injury.
• Do not strike jammed bits with a hammer to dislodge them.
Fragments of metal or material chips could dislodge and
cause injury.
• Slightly worn chisels can be resharpened by grinding.
• Keep the power cord away from the rotating bit. Do not
wrap the cord around any part of your body. An electric cord
wrapped around a spinning bit may cause personal injury and
loss of control.
WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA or less.
Residual Risks
The following risks are inherent to the use of rotary hammers:
• Injuries caused by touching the rotating parts or hot parts of
the tool.
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment of hearing.
• Risk of personal injury due to flying particles.
• Risk of burns due to accessories becoming hot
during operation.
• Risk of personal injury due to prolonged use.

Electrical Safety

The electric motor has been designed for one voltage only.
Always check that the power supply corresponds to the voltage
on the rating plate.
Your BERNER tool is double insulated in accordance
with EN60745; therefore no earth wire is required.
WARNING: 115 V units have to be operated via a fail-safe
isolating transformer with an earth screen between the
primary and secondary winding.
If the supply cord is damaged, it must be replaced by
a specially prepared cord available through the BERNER
service organisation.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.
WARNING: No connection is to be made to the
earth terminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 13 A.
Using an Extension Cable
An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for the
power input of your tool (see Technical Data). The minimum
conductor size is 1.5 mm²; the maximum length is 30 m.
When using a cable reel, always unwind the cable completely.
