5.4 Work operation
Before starting to work with the loader:
•
Survey the work area to determine if people, vehicles and obstacles are in the immediate work area. Do not start work until the work area is clear.
•
Constantly survey the area during working operation to avoid collision with people, vehicles and obstacles that may inadvertently enter the loader work area.
•
Verify that all controls are working correctly and the indicator lights are functioning. Move the lift arm and attachment hydraulics to assure smooth control response.
•
Jerky, spongy or delayed control response may indicate that air has entered the hydraulic system. Cycle the hydraulic system a few times. If the controls become smooth, the air has been eliminated from the system. If the problem persists, do not operate the machine in this condition. Advise the supervisor and have a technician determine the source of air entrainment.
• Inspect attachments to confirm they are in ser
viceable condition and are properly connected to the loader arms.
In the event of power loss (failure of the engine and/ or driving or working hydraulics), lower the loader lift arms to the ground immediately and relieve the control circuits and hydraulic lines of pressure. Read
Section 7, page 135 »Lowering loader arms«.
