Operation Controls 2-15
When the bucket manipulating handle is again pulled back-
wards to the extreme left position, the manipulating handle
will not be stuck by Bucket Receive holding magnet (it will
return back to the middle position under the force of spring
when you release your hand) because the Bucket Receive
holding magnet is de-energized all the time due to the
Limiting and Holding function of the bucket leveling limit
switch. Only when you push manipulating handle forwards
and the tilting of bucket (unloading) exceeds the bucket
leveling position, can the bucket leveling limit switch be
reset and the bucket auto leveling function be restored. At
this time, if the manipulating handle is again pulled back-
wards to the extreme left position, the manipulating handle
will be held at the Extreme Left Position.
The manipulating handle does not have holding function
when it is at the front position. When the bucket tilts out-
wards from the maximum bucket receive angle to the un-
loading angle, you need, at all time, push the manipulating
handle in excess rightwards(the manipulating handle will
return back to the middle position under the force of spring
when you release your hand), which will not stop even
when the bucket passes the leveling position. When shov-
eling and loading, you should fully use arm lifting limit, arm
floating device and bucket leveling limit device, which will
effectively reduce the labor intensity of to operate the ma-
nipulating device, thus improving the comfort of operation.
