TESTING AND ADJUSTING
RESETTING PROCEDURE OF ELECTRIC SYSTEM
AND CHECK OF ITS OPERATION
5. Automatic stop position is closer than
specified value
★
Even if the value is slightly closer than the
specified value, there is no problem in
actual operations, so except in special cases
(for example, a request from the user), do
not carry out the resetting (adjustment)
operation unnecessarily.
• Carry out the resetting (adjustment) opera-
tion as follows.
1) Operate the arm in the OUT direction and
move the bucket about 400 mm away from
the cab.
2) Set cancel switch (4) to the ON (automatic
return) position, operate the arm slowly in
the IN direction, and set distance L between
the tip of the bucket teeth and the cab to
260 -- 300 mm.
★
Because of inertia when stopping, the
work equipment will move about 50
mm closer than the set position, so
allow a margin when setting.
3) Turn the starting switch OFF and stop the
engine, then turn the starting switch ON
again.
4) Set the mode selection switch to DEPTH
SET 0, then connect reset power supply ter-
minal (1) and reset terminal (2).
★
Reset power supply terminal (1) is a
female 1-pin connector (red wiring har-
ness).
Reset terminal (2) is a male 1-pin con-
nector (yellow/white wiring harness
without tape).
5) Check that the electrical system caution
lamp on the monitor panel starts to flash 2
seconds later in a 1-second cycle.
6) Disconnect terminals (1) and (2), then turn
the starting switch OFF.
7) When the starting switch is turned ON
again, the resetting operation is completed.
8) After finishing the operation, tape the reset
terminals to their original positions.
