TESTING AND ADJUSTING
RESETTING PROCEDURE OF ELECTRIC SYSTEM
AND CHECK OF ITS OPERATION
7. Action to be taken when an abnormality
display (error code) is given for Items 5 or
6 (resetting automatic stop position)
★
For details of the abnormality, see Item 2,
Table 1.
• The adjustment range for the automatic
stop position is 300 mm to the front and
rear of the automatic stop position, so with
the normal reset, there is no reset error, but
if an abnormality display is given, carry out
the resetting stop position into the range
that does not give any abnormality display.
★
Adjustment range:
Automatic stop position ± 300 mm
★
If the above resetting operation causes any
problem with normal operations, carry out
the resetting operation again from "1. Reset
potentiometer input signal".
★
If an abnormality display appears during
the resetting operation, remove all the
causes, then reset the system properly.
8. Move position of bucket to left and right and
check automatic stop position
• If the automatic stopping distance has been
reset in Item 5 or Item 6, move the bucket to
the maximum left offset and the center of
the cab, carry out the automatic stop, and
check that there is no extreme difference
between the distance set previously and the
actual distance from the tip of the bucket
teeth to the cab.
1) Set the bucket to maximum left offset posi-
tion (1) and carry out the automatic stop.
2) Set the bucket in line with cab center (2) and
carry out the automatic stop.
★
When measuring after stopping, set the
bucket in a horizontal position.
