Operation
3.25 Changeover valve for control pattern’’B’’(option)
Important!
Possible loss of machine control. Changing the control valve mode selection posi-
tion will reverse the function control of the hand levers. The left hand lever controls
the boom, not the stick. The right hand lever controls the stick.
• Confirm the selected mode before starting the engine to avoid uninten-
tional movement of the stick or boom.
• Always secure wing nut J on the directional valve's changeover lever.
