3.3
1)
The given speeds are to be viewed as maximum speeds for the given wet diamond bit diameters.
Depending on the property of the material to be drilled, such as concrete with steel reinforcement of
different thicknesses, the speed is set “by feel”. When drilling through concreted in steel with large wet
diamond core drill bit diameters the 1st gear is always set.
2) Weight according to EPTA procedure 01/2003.
3)
Measured values for noise determined according to EN 60745. Wear hearing protection!
4) Total vibration values (vector sum in three directions) determined according to EN 60745
The vibration emission values given in this instruction manual have been measured according to a method
of measurement standardised in EN 60745 and can be used for comparison between power tools. They
are also suitable for a preliminary estimate of the vibratory stresses.
The vibration emission values given represent the main applications of the power tool. If the power tool is
used for other applications, with different insert tools or are insufficiently serviced, this can significantly
increase the vibratory stresses over the whole work period. For a precise estimate of the vibration
emission values, the times during which the tool is switched off or is running but not actually in use should
also be taken into account. This can reduce the vibration stresses over the whole work period significantly.
WARNING
Health risk due to vibrations.
Î
Additional safety measures should be taken to
protect the user, e.g. wearing anti-vibration pro-
tective gloves, correct maintenance of power
tools and insert tools, keeping hands warm and
good organisation of work sequences.
