Residual Risks; Electrical Safety - Berner BHD-4-32 Manual De Instrucciones

any other condition that may affect the power
tool's operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
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 Specific Safety Rules 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 or
the fastener 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 30 mA 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 squeezing fingers when changing the accessory.
• Health hazards caused by breathing dust developed when
working in concrete and/or masonry.

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 charger (see Technical Data). The
