HYDRAULIC TANK LEVEL SENSOR
CALIBRATION
See Figure 2-33 for the following procedures.
The following calibration procedures apply only to crane
Serial Number 18001082 and newer.
Perform the calibration procedures:
• If you are installing a new level sensor (1)
• If you see faulty level readings in the digital display
Empty Calibration
1. In the operator cab, turn the engine stop/run/start switch
to the STOP position.
2. Disconnect electric cable (4) from level sensor (1).
3. Remove level sensor (1) from hydraulic tank (3).
4. Wipe the level sensor rod dry with a clean rag.
5. Depress CAL button (5) hold.
6. Turn the engine stop/run/start switch to the RUN
position.
7. Connect electric cable (4) to level sensor (1) while
continuing to hold the CALL button down for 5 more
seconds.
8. Release the CAL button.
9. Empty calibration is now set. The hydraulic oil level in
the digital display should read 0%.
10. Turn the engine stop/run/start switch to the STOP
position.
11. Disconnect electric cable (4) from level sensor (1).
12. Securely install adapter (2) and level sensor (1).
Apply Loctite® 569 to the threads of the adapter and the
level sensor.
13. Connect electric cable (4) to level sensor (1).
14. Perform the Full Cold Calibration procedure.
Full Cold Calibration
Perform the following calibration procedure when the
hydraulic oil is cold.
1. In the operator cab, turn the engine stop/run/start switch
to the STOP position.
2. If not already done:
a. Securely install adapter (2) and level sensor (1).
Apply Loctite® 569 to the threads of the adapter and
the level sensor.
b. Connect electric cable (4) to level sensor (1).
3. Fill the hydraulic tank with approved hydraulic oil to the
FULL COLD mark on sight gauge (5).
4. Turn the engine stop/run/start switch to the RUN
position.
5. Depress the CAL button on the top of the sensor and
hold for 5 seconds to set full cold calibration.
6. Full cold calibration is now set. The hydraulic oil level in
the digital display should read 100%.
NOTE: As the hydraulic oil warms up, the level in the digital
display will rise to a maximum of 110% when the oil
is at FULL HOT mark on the sight gauge.
