Lifting Height Upper Limit Switch and
LED (Orange)
Use this switch to set or cancel the lifting height
upper limit.
While the lifting height is restricted by detecting
the height of the tip of the boom, the lifting height
on the display panel shows the lifting height
when the hook was raised to the over winding
detection status.

Setup
With no upper limit value being set, set the boom
to the lifting height you would like, and press the
switch for 2 seconds.
The lifting height at this point is set as the upper
limit.
At the same time, the LED lights up indicating
that the upper limit value was set.
To enable this setting, turn the key switch to the
"ON" position again after turning it to the "OFF"
position, or reduce the lifting height by "1.3 m" or
more from the set lifting height to get out of the
pre-warning zone while the engine is being
started.
NOTICE: Be sure to verify that the boom
automatically stops at the set lifting height before
performing the actual operation. If the boom does
not stop automatically, re-set the lifting height
using the procedure above.
When the boom reaches the pre-warning zone or
stops at the upper limit with the lifting height
upper limit set, the lifting height upper limit LED
flashes.
Cancel
With the upper limit value being set (LED ON),
press the switch for 5 seconds.
The current upper limit value setting will be
cleared. At the same time, the LED goes off
indicating that the upper limit value setting is
cleared.
NOTICE: The setting and cancelling will not
repeat even if you keep the switch pressed for
more than 2 seconds. Let your hand go off the
switch and press the switch again.
