13. MAINTENANCE STANDARD AND TEST PROCEDURE
13.3 MEASUREMENT OF ENGINE SPEED
13.3.1 MEASUREMENT OF ENGINE SPEED
(1) Warming up of engine
Start engine to raise the coolant temperature of
engine to 60 to 90°C (140 to 194°F) at surface of
radiator upper tank.
The E/G coolant temperature gauge is used to
measure. The range in white color shows the
temperature of approx. 65 to 105°C (149 to 221°F),
so confirm that the pointer indicates the
temperature within the white range.
(2) Engine speed measured value through service
diagnosis (See Fig. 13-2)
1) Turn "ON" the starter switch with the buzzer stop
switch pressed.
2) A program No. and an actual engine revolution
are displayed as the No.2 Item.
3) The screen advances -- No.2, No.3, etc. -- each
time the wiper switch on the gauge cluster is
pushed.
4) The screen returns -- No.45, No.44, etc. -- each
time the "washer switch" is pushed.
5) The display does not disappear unless the
starter switch is turned to"OFF".

13.6.3 PERFORMANCE OF SWING PARKING BRAKE
(1) Purpose
To confirm the mechanical performances of the
swing parking brake that is fitted to the inside of the
swing motor.
(2) Conditions
On a slope of 15 degree incline.
Stop the machine at right angles with the slope. Put
the bucket empty, retract the arm cylinder fully and
extend the bucket cylinder fully. And move the
boom so that the arm top pin is positioned at same
height with boom foot pin.

13. MAINTENANCE STANDARD AND TEST PROCEDURE
(5) When the adjustment of unloading valve only is performed; ("C" adjustment)
In the event where only unloading valve and unloading proportional valve are
replaced, perform the adjustment of unloading valve only.
Procedure
1) Turn starter switch ON keeping the work mode selector switch on the gauge
cluster pressed, and hold it for 5~10 seconds, and then release it.
(If the engine is started, the following indication is not displayed. Therefore, do
not start the engine.)
2) Keep buzzer stop switch on gauge cluster pressed for 5 seconds and release
it and the screen for selection of adjustment type is displayed. And "ADJUST"
is displayed.
When adjustment data is not entered in mechatro controller, "READY" is
indicated. If the adjustment operation is once performed, "FIN" is indicated.
And the lever lock solenoid is automatically released, disabling all operations.
3) Change the adjusting items with washer switch ( ) and wiper switch ( ), and
select "ADJUST UNLOAD". (See Fig. 13-35)
Like the output adjustment, when adjustment data is not entered in mechatro
controller, "READY" is indicated. If the adjustment operation is once
performed, "FIN" is indicated.
4) Press selector switch on gauge cluster to display "START ENG".
"ENGINE SPEED", P1, P2 "PUMP PRESSURE" and "STEP" (acceleration
command voltage) are indicated.
5) After starting engine, press selector switch on gauge cluster and "MEMORY

UNLOAD" is indicated, the engine speed is automatically increased and the ENGINE SPEED
adjustment of unloading valve is performed. PUMP PRESSURE

(acceleration command current) are indicated.
6) When the unloading proportional valve operates to the specified value, the
adjustment of unloading proportional valve automatically completes. "FINISH
UNLOAD" is indicated.
The speed is shifted to the speed corresponding to acceleration potentiometer.
The value of adjusting current is indicated on the display of current of P1 and
P2 unloading proportional valves. The adjusting range is usually 520~635mA.
Stop the engine. (The adjusted data is automatically stored.)

21. MECHATRO CONTROL SYSTEM
(1) Positive control
1) When beginning an operation, pilot secondary pressure switches each spool and enters each low pressure
sensor.
2) The output voltage of low pressure sensor is input to mechatro controller and the mechatro controller
processes pilot signal and outputs command according to the input voltage to each unload pressure
proportional valve.
3) Each pump proportional valve outputs pilot secondary pressure according to the command output by
mechatro controller and changes the swash plate angle of each pump and controls the pump output.
4) With this operation, the delivery rate according to lever manipulated movement is fed to the actuator, and
consequently the working speed according to the lever manipulated movement will be obtained.
(2) P-Q control
1) The output voltage of high pressure sensor provided on each pump line is input to mechatro controller and
the mechatro controller processes pilot signal and operates the command according to the input voltage
(load pressure).
2) The lower value between command values calculated by positive control and operated value found by P-Q
control {operated value found in item 1)} is selected and is output to each pump proportional valve as
command value.
3) Each pump proportional valve outputs pilot secondary pressure according to the command output by
mechatro controller and changes tilting angle of each pump and controls the delivery rate.
4) With this operation, the delivery rate according to lever manipulated movement is fed to actuator and
consequently working speed will be obtained according to lever movement.
