Attention: The Otto arms may only
be used on lifts with 4 tons of steel
construction. The lifting capacity
will be reduced to 3500 kg when
the Otto arms are used.
3.2 Safety devices
• Over-pressure valve
Hydraulic system fuse against over-pressure.
• Check valve
Secure the vehicle against unauthorised lowering.
• Main switch with curtain lock device
Fuse to prevent unauthorised use.
• Two independent cylinder systems (each with
a command, follow system)
Secure against unauthorized lowering of the lift.
• Deadman controls
Lift movement stops when the operating lever is re-
leased.
• CE-STOP
• Lifting arm block
Secures the lifting arm against horizontal movement in
a lifted condition.
• Operating lever with curtain lock device
Fuse to prevent unauthorised use.
