TROUBLESHOOTING
Troubleshooting
• Check all fuses inside the control panel(s). Replace
any blown fuse(s) with a fuse of equal specification.
• Make sure the correct voltages are present at the
proper locations inside the control panel(s).
Before performing the detailed troubleshooting procedures, check the following items first:
When service under the dock leveler is required,
always lock all electrical disconnects in the OFF
position after raising the platform and engaging the
maintenance prop. Failure to do this may result in
serious personal injury or death.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
maintenance is complete. Failure to do this may
result in serious personal injury or death.
