TEST COOLING FAN SPEED
k
Place the machine on a level ground, and then lower the work equipment completely to the ground in
a stable posture. Set the lock lever to LOCK position, and then stop the engine.
For testing the cooling fan speed to perform troubleshooting, refer to this section.
METHOD FOR TESTING COOLING FAN SPEED
1.
Start the engine.
2.
Select “Fan Speed Mode Select”, and select 100 % mode. See “SET AND OPERATE MACHINE MONI-
TOR”.
3.
Select “Pre-defined Monitoring” (11/11) or “Monitoring Se-
lection Menu” and display the following monitoring items
by referring to “SET AND OPERATE MACHINE MONI-
TOR”.
Monitoring code: 10007 “Fan Speed”
4.
Check the cooling fan speed when the fuel control dial is in
MIN (Low idle) position, PARTIAL (Engine speed
1200 rpm) position, and MAX (High idle) position.
See STANDARD VALUE TABLE, “STANDARD VALUE TA-
BLE FOR MACHINE” for standard values.
REMARK
If 100 % mode is not selected in “Fan Speed Mode Select”, the cooling fan speed is set to 500±100 rpm
when the engine coolant temperature is below 85 °C and hydraulic oil temperature is 30 °C. When the en-
gine coolant temperature and hydraulic oil temperature exceed the above level, the cooling fan speed var-
ies with the temperature.
5.
After testing, select the normal control mode on “Fan Speed Mode Select” by referring to “SET AND OPER-
ATE MACHINE MONITOR”.
REMARK
If you turn the starting switch to OFF position, the cooling fan speed is set in the normal control mode when
the engine is started again.
