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 conrm 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 125 »Lowering loader arms«.
