Continuous mode
When switch is operated to the limit of position (C), the set
maximum flow is held and the third attachment continues the
operation even if the switch operation is stopped. This action is
called the detent control.
Use this control when the installed attachment requires contin-
uous hydraulic oil flow.
Detent control operation pilot lamp (D) lights up during the de-
tent control.
The detent control is canceled by any of the following opera-
tions.
• Operate the switch again.
• Turn the work equipment lock switch ON.
• Turn the starting switch key to OFF position.
• Stop the engine.
• Cancel the continuous mode on the monitor.
Proportional mode
This mode does not have the detent control function which the continuous mode has.
REMARK
The hydraulic oil discharged volume is in proportion to the stroke of the switch in both continuous mode and
proportional mode.
