[3] BOOM ANGLE LOWER LIMIT SWITCH
Use this switch to set or reset the boom angle lower limit.
[Setting]
With no value being set for the lower limit angle, move the
boom to an angle you want to set as an upper limit angle,
and push and hold the switch for 2 seconds.
The boom angle at this time will be set as a lower limit
angle.
At the same time, the illuminated blue indicator lamp on the
switch turns orange to indicate that the lower limit angle
has been set.
To enable this setting, turn the key switch to the “OFF” position and then turn it to the “ON”
position again, or raise the boom with the engine running so that the boom angle becomes larger
than the set value by at least “7 degrees” to get out from the warning alarm zone.
NOTES
Before performing a practical operation, be sure to check if the boom automatically stops at the
specified angle. If the boom does not stop, set the boom angle again by repeating the
procedure mentioned above.
[Resetting]
To reset the lower limit angle that has been set (the indicator lamp is illuminating in orange), push
and hold the switch for 5 seconds,
The currently effective lower limit angle will be reset. At the same time the illuminated orange
indicator lamp at the switch turns blue to indicate that the set value for the lower limit angle has
been reset.
NOTES
The setting and resetting operations cannot be performed in a row even if the switch is touched
and held for 2 seconds. To perform these operations consecutively, release your finger from
the switch between each operation.
[4] WORKING RADIUS LIMITER SWITCH
Use this switch to set or reset the upper limit for the
working radius.
[Setting]
With no value being set for the upper limit, move the boom
to a working radius you want to set, and push and hold the
switch for 2 seconds.
The working radius at this time will be set as an upper limit.
At the same time, the illuminated blue indicator lamp on the switch turns orange to indicate that
the upper limit for the working radius has been set.
To enable this setting, turn the key switch to the “OFF” position and then turn it to the “ON”
position again, or move the boom with the engine running so that the working radius becomes
smaller than the set value by at least “1.3 m” to get out of the boom from the warning alarm zone.
NOTES
Before performing a practical operation, be sure to check if the boom automatically stops at the
specified working radius. If the boom does not stop, set the working radius again by repeating
the above procedure.
