Work operation 5.4
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 con-
trol circuits and hydraulic lines of pressure. Read
section 7 page 133 »Lowering loader arms«.
