Daily preoperational checks
The aerial device should be inspected at the beginning of each work day, before going
out on the job. By spending a few moments every day inspecting the unit, potential service
and safety problems may be detected.
The following inspections and tests shall be
performed by the operator immediately prior to first use at the beginning of each
shift
.
The following items should be checked during the daily pre-operation inspection.
1. Check the oil level of the hydraulic reservoir. The oil level must be between the Add
and Full marks on the sight gauge with the truck on level ground, booms in the rest
position. If necessary, add oil of the proper type as described in the Maintenance
Manual. The need to add oil on a regular basis indicates a leak in the hydraulic system
