4.3 Seals
19 X 0.9 X 45 mm / 3/4" X.035 X 1 3/4", push-type with overlapping flanges
4.4 Joint
Joint strength: approx. 75% of the tensile strength of the steel strap
A double-notch (two pairs of cut notches) is made per cycle.
4.5 Sound information
The A-weighted equivalent continuous sound level at the work place of the machine operator is
typical 83 dB (A).
This value was determined according to DIN 45 635 T3 (11.85).
4.6 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).

5.1 Compressed air connection
The compressed air should be connected to the tool preferably by a quick disconnector.
It is very important to clean the compressed air with an air unit consisting of a separator for water and dirt, a
pressure regulator with a manometer and a lubricator (see sketch).
Compressed air
Joining thread: G1/4
Working pressure: 5 bar / 72.5 psi
Max. air pressure: 6 bar / 87 psi.
Air flow of air unit: min. 780 Nl/min / 27.55 cu.ft /min with a maximum pressure drop of 0.5 bar / 7.25 psi.
Air consumption
Tensioning: approx. 3.5 Nl / 0.12 cu.ft uncompressed air per second with the air motor running.
Sealing: approx. 7.7 Nl / 0.27 cu.ft. uncompressed air per cycle.
