REMARK
• When the key in starting switch (2) is turned to OFF
position, the engine stops but the power supply to the
machine is not turned OFF immediately.
During this period, the power is supplied to the con-
troller to save the operating condition and then finish
the system. The time to keep supplying the power de-
pends on the operating condition.
• Also when the cooling fan is used for a cleaning pur-
pose, the machine's main power supply is not turned
off immediately, even if engine starting switch (2) is
turned to OFF position.
This is for protection of the hydraulic circuit, and the
power is kept supplied for 7 seconds.
• If the starting switch (2) key is turned to OFF (A) posi-
tion while the engine is still hot, guidance (3) may be
displayed on the machine monitor. To cool down the
engine before stopping, run it at low idle for approxi-
mately 5 minutes, because it may cause damage to
the devices.
