Sound information
The A-weighted equivalent continuous sound level at the work place of the machine operator is
typical 82 dB (A).
This value was determined according to DIN 45 635 T3 (11.85).
4.5
Vibration information
The weighted effective value of the acceleration typically amounts to less than 2,5m/s
2
.
This value was determined according to DIN EN 28 662 T1 (01.93).

INSTALLATION
5.1
Compressed air connection
The compressed air is connected to the hose angle N6.5108 using a coupling. An air-unit consisting of a
separator for water and dirt, a pressure regulator with a manometer and a lubricator should be installed within
a range of 15 ft / 5 meters. The compressed air must be free from dirt, rust and moisture.
For special attention:
The allowed maximum pressure adjusted at the manometer of the air unit is 5 bar/ 70 psi.
5.2
Suspension of tool
The tool should always be suspended on a balancer. The suspension bracket A3H.1803 which is supplied
with the tool as a standard item allows the use of the tool in the normal and vertical position. Using the tool in
the horizontal position the suspension bracket A3H.1811 should be ordered as an optional item. The
suspension bracket A3H.1812 is offered for using the tool in both positions.

Quality:
Fundamentally the A3H allows the use of all current steel straps with tensile strengths
ranging from 700 to 850 N/mm

(100 000 - 123 000 psi).
Straps with a low breaking elongation are unsuitable for the A3H tool.
