NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
given in EN 61029 and may be used to compare one tool with another. It may be used for a preliminary assessment
of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is
used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total working period. An estimation of the level of exposure to
vibration should also take into account the times when the tool is switched off or when it is running but not actually
doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety
measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.

5 Safety instructions

5.1 Basic information concerning safety
a) CAUTION: The following basic safety instructions
must be followed when using electric tools or
machines to ensure protection against electric
shock, risk of injury and fire hazards.
b) Read all instructions before using this electric tool
or machine and keep the safety instructions in a
safe place.
5.1.1 Proper organization of the work area
a) Approval must be obtained from the site engineer
or architect prior to beginning drilling work. Drilling
work on buildings and other structures may influence
the statics of the structure, especially when steel
reinforcing bars or load-bearing components are cut
through.
b) Ensure that the workplace is well lit.
c) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.

d) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
e) When drilling through walls, cover the area behind
the wall, as material or the core may fall out on
the other side of the wall. When drilling through
ceilings, secure (cover) the area below as drilled
material or the core may drop out and fall down.
Wear personal protective equipment. Wear eye

protection.
g) Wear respiratory protection if the work causes
dust.
h) Dress properly for the work. Do not wear loose
clothing or jewelry as it could be caught in moving
parts. Contain long hair.
i) It is recommended that rubber gloves and non-
skid shoes are worn when working outdoors.
Keep children away. Keep other persons away

from the working area.
k) Children must be instructed not to play with the
machine.
l) The machine is not intended for use by children,
