Safety Devices; Locking The Controls; Locking The Swivel Frame - Kubota U17-3a Operating Instructions Manual

Safety rules

Safety devices

Before starting the excavator, all safety devices must be installed properly and operational. No manipulation of
safety devices, e.g. the shorting of limit switches, is allowed.
Protective devices may only be removed after

The excavator is standing still and the engine is stopped

and secured against restarting (starter switch in STOP position and key removed).

Locking the controls

The left and right control levers (2 and 3) and the drive levers (1)
are completely disabled when the console (4) is raised. This
allows safe getting on and off. The console is unlocked and
raised with the control lever lock (5).
The functionality for the boom swing and the dozer,
however, are not affected by the control lever lock.

Locking the swivel frame

If the swivel frame lock (1) is in the bottom position, the swivel
frame and the track frame are interlocked.
Prior to locking the swivel frame, the swivel frame
and the track frame have to be aligned together in a
parallel position.
