Technical Data
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 86 dB(A); Sound power level 97 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a
h
(triax vector sum) and uncertainty K
determined according to EN 60745:
Drilling into metal: a
h
=3.0 m/s 2 , K<1.5 m/s 2 .
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 in-
crease 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 sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.

Assembly
 Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 5.
Screw the auxiliary handle 5 into the thread 4 on the gear
head.
Changing the Tool (see figure A)
Drilling tools with a MK3 morse taper can be inserted directly
into the tool holder 1. For drill bits with MK2 morse taper, use
the reducing sleeve 10.
Pay attention that the morse cone and the morse taper are
free of grease.

Protection class / II
The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
Starting cycles generate brief voltage drops. Interference with other
equipment/machines may occur in case of unfavourable mains system
conditions. Malfunctions are not to be expected for system impedances
below 0.36 ohm.
