Troubleshooting
Always stand clear of the dock leveler lip when
working in front of the dock leveler. Failure to do
this may result in serious personal injury or death.
The platform maintenance prop MUST be in the
service position when working under the dock
leveler. For maximum protection, use an OSHA
approved locking device to lock the maintenance
prop in the service position. Only the person
servicing the equipment should have the key to
unlock the maintenance prop.
Failure to follow these instructions 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.
