If the steering oil pressure caution lamp (red) (3) lights up, move the machine immediately to a safe place and
stop it there.
Do not operate the machine until the cause is identified and it is repaired.
REMARK
When engine is running at
low speed and when you use some hydraulic system functions, the steering low oil
pressure pilot pump (red) (2) may light up temporarily. There is no problem if the lamp is lit only momentarily.
When the secondary steering system detects the recovery of the oil pressure in the steering system, the secon-
dary steering system stops its actuation.
METHOD FOR OPERATING WORK EQUIPMENT
WARNING
Never perform the boom RAISE operation with the machine articulated and the bucket full. There is a
danger that the machine may tip over.
NOTICE
Even if the engine is
stopped, if the starting switch is at ON position and lock of the work equipment is
canceled (pilot lamp is not lit), the work equipment can move.
The multifunction mono-lever (1) is used to operate the boom
and bucket in the following manners.
METHOD FOR OPERATING BOOM
The multifunction mono-lever is used to operate the boom.
NOTICE
Do not use “FLOAT” position when lowering the bucket.
Use “FLOAT” for leveling work.
Position (a): RAISE
When the multifunction mono-lever is pulled further from the
“RAISE” position, the lever stops in that position.
When the remote boom positioner is enabled, the boom stops
at the preset position and the lever returns to “HOLD” position
at the same time.
The boom stops at the highest position and the lever returns to
“HOLD” position at the same time when the remote boom posi-
tioner is disabled.
Position (b): HOLD
The boom remains in the position where it was stopped.
Position (c): LOWER
Position (d): FLOAT
The boom moves freely under external force. When the multi-
function mono-lever is set at “FLOAT” position, the lever stops
in that position.
