carrier, the hydraulic attachment can be operated using
the carrier‘s hydraulic system. All functions for normal
carrier operation remain intact.
The hydraulic attachment is switched on and off using
electrical and hydraulic signals.
If you have any questions about electric / hydraulic com-
mands, consult the carrier manufacturer and/or the au-
thorized Customer Center / Dealer in your area.
