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 op-
eration 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 sys-
tem. Cycle the hydraulic system a few times. If
the controls become smooth, the air has been
eliminated from the system. If the problem per-
sists, do not operate the machine in this condi-
tion. Advise the supervisor and have a techni-
cian 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.
