SETUP
典
In the status where the lower limit is not set, set the angle for the boom
and press the switch for two seconds or more. This boom angle is set
as the lower limit.
At the same time, the LED comes on to notify that the lower limit has
been set.
To enable this setting, set the key switch to OFF once, and then set it to ON. Another way to enable this
setting is to raise the boom 7° or more over the specified angle to place the boom out of the advance warning
range while the engine is running.
NOTES
Before starting the actual work, be sure to check if the boom automatically stops at the specified angle. If the
boom does not automatically stop, set the boom angle again by implementing the above procedure.
If the boom enters the advance warning range or stops due to the lower limit restriction in the status where
the boom angle lower limit is set, the boom angle lower limit LED will blink.
