TROUBLESHOOTING

The troubleshooting guides are designed to provide logical starting points to locate general problems that could occur
with lift. However, not all possible problems or combinations of problems are listed. For troubleshooting lift, refer to
Table 3-2. The guide does not incorporate routine safety precautions or preliminary procedures, and assumes that ve-
hicle battery is fully charged and battery terminals/connectors are clean and tight.
THE TROUBLESHOOTING GUIDES DO NOT INCORPORATE ROUTINE SAFETY PRECAUTIONS
OR PRELIMINARY PROCEDURES. DURING THE RICON WARRANTY PERIOD ONLY A
TRAINED, AUTHORIZED RICON SERVICE TECHNICIAN CAN PERFORM TROUBLESHOOTING.
AFTER THE WARRANTY PERIOD, IT IS RECOMMENDED THAT TROUBLESHOOTING
CONTINUE TO BE PERFORMED BY AN AUTHORIZED RICON SERVICE TECHNICIAN.
