43EXCAVATOR OPERATION
7. Press the switch 2 or 3 to preset the maximum flow
volume.
Set the bar to the highest level, and the flow volume
will be maximized.
Set the bar to the lowest level (no bar displayed), and
there will be no oil flow.
Then press the switch 4 to go to the next port, and
make the settings for all the other ports.
A Some attachments might not be activated even when
the bar level is still somewhat above the lowest
position. Or even when the bars of ports 1 and 2 (or of
ports 3 and 4) are at the same level, the same speed
might not be achieved. This does not indicate a
machine problem, however. Readjust the bar to the
optimum level according to your attachment manual.
A Suppose that the same attachment is mounted on
another machine. Even if the same flow control setting
is made, the same speed cannot be achieved. Make
an optimum setting on each machine.
8. Go back to Step 3 to make settings for the next action
mode. When all the settings of all the action modes
have been made, press the switch 1 to return to the
normal screen.
C AUX port MAX. Flow volume
A When the AUX port is not used for a long period, dirt
particles can settle in the lower part of the AUX port
lines. When the plugs on the AUX port lines are
removed to connect attachments, drain approx. 100 cc
(3.4 oz) of oil before making connections.
