5. Fault Finding
In the event of faulty operation, the following procedure is recommended.
•
Check that all moving components are clean and are able to move freely and that they are
free from any obvious damage or wear.
•
If the lift fails to raise:
1.
Check the fuses.
2.
Use a test meter to check that the correct voltage is present at the motor terminals when
the control buttons are operated. If the voltage is low/missing, check back through the
circuit to locate the loss of voltage, usually a loose or dirty connection is the cause (on DC
units- finally, check the condition of the motor brushes and their freedom to move).
•
If the lift fails to lower:
1.
Check the fuses.
2.
Check the voltage at the dump solenoid – if all is OK then the solenoid has probably failed.
If not check back check back through the circuit to locate the loss of voltage.
•
If the table drifts/drops slightly over time:
1.
Visually check for leaks throughout the system (Power pack, ram, hose) (possible seal
failure).
2.
Check dump valve solenoid – could be debris under the seating or a valve failure.
