5-pin levers are used in systems G1 - Old system.

The manoeuvre levers give fully variable proportional operation and are sprung loaded to return to zero position, i.e. "dead-man’s-handle". When the manoeuvre levers are moved from zero position the respective hydraulic function starts to operate slowly and increases in speed as the lever is moved further from zero position and vice versa as the lever is moved back towards zero position. If any levers are not included for a particular installation, a cover plate can be mounted for the unused lever locations.
