COMPRESSOR
CAUTION
When the maximum, operating pressure of the air
compressor exceeds 23 bar, be sure to provide a
reducing valve between the air compressor and screw
driver. Then, adjust the air pressure within the operating
range of 18 – 23 bar. If the air set is installed, lubrication
is also possible, thus providing additional convenience.

Noise Information
Noise characteristic values in accordance with EN 792-13,
JUNE, 2000:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
Uncertainty KpA: 2.5 dB (A).
These values are tool-related characteristic values and do
not represent the noise development at the point of use.
Noise development at the point of use will for example
depend on the working environment, the workpiece, the
workpiece support and the number of driving operations, etc.
Depending on the conditions at the workplace and the form
of the workpiece, individual noise attenuation measures
may need to be carried out, such as placing workpieces on
sound-damping supports, preventing workpiece vibration by
means of clamping or covering, adjusting to the minimum air
pressure required for the operation involved,etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance with
EN 792-13, JUNE, 2000 : 3.4 m/s
Uncertainty K = 1.5 m/s
2
This values is a tool-related characteristic value and does not
represent the infl uence to the hand-arm-system when using
the tool. An infl uence to the hand-arm-system when using
the tool will for example depend on the gripping force, the
contact pressure force, the working direction, the adjustment
of energy supply, the workpiece, the workpiece support.
