C.3.2 Compressed air
The compressed air connection is preinstalled on the
machine. It comprises the following components:
•
Pressure reducer
1 with manometer 4 and water
separator
3,
• Pressure hose with push-in plug
2.
The pressure reducer is mounted to the side mounting wall
of the worktable.
Connecting the machine to the compressed air sup-
ply system:
1. Connect pressure hose plug to on-site terminal unit.
2. Open on-site compressed air supply.
3. Set pressure reducer to a machine operating pressure
of 6 bar by rotating pressure reducer knob
5 and read
value on manometer
4:
• To increase pressure, rotate in clockwise direction,
• To reduce pressure, rotate in counter-clockwise di-
rection.
Setting pressures:
The operating pressures are set at the three valves:
•
To increase the pressure, rotate the switch in the clo-
ckwise direction.
• To reduce the pressure, rotate the switch in the counter-
clockwise direction.
Function of the valves:
•
Pneumatic spring 6: approx 0.4 bar, controls the tra-
veling speed of the clamp to the stop.
• Downholder 7: approx 0.4 bar, controls the pressure
of the roller on the clamp.
• Clamp pressure 8: 0.4 - 0.5 bar, controls the pressu-
re of the clamp on the sewing material.
