Operation
If the levers are operated within 15 seconds after the engine
stops, it's possible to lower the work equipment to the ground. In
addition, the levers can also be operated to release any remain-
ing pressure inside the hydraulic cylinder circuit and to lower the
boom after loading the machine on a trailer.
NOTE
This is only possible if the key is returned to the "ON" position
after the engine is stopped.
Hydraulic adjust boom operation:
Depress front of pedal (29) to extend the boom and the rear of
the pedal to retract the boom.
