MACHINE OPERATIONS AND CONTROLS
WORK EQUIPMENT CONTROLS AND OPERATIONS
If the lever is operated when the auto-deceleration is being actuated, the engine speed will suddenly
rise, so be careful when operating the lever.
If the work equipment control lever is operated quickly, the work equipment will move quickly; if the
lever is operated slowly, the work equipment will move slowly.
The work equipment is operated by the left and right work
equipment control levers. The left work equipment control lever
operates the arm and swing, and the right work equipment con-
trol lever operates the boom and bucket.
The movements of the lever and work equipment are as shown
in the diagrams on the right. When the levers are released,
they automatically return to the neutral position and the work
equipment is held in place.
If the work equipment control levers are returned to the neu-
tral position when the machine is stopped, even if the fuel
control dial is set to FULL, the auto-deceleration mecha-
nism will act to reduce the engine speed to a mid-range
speed.
REMARK
With this machine, an accumulator is installed in the oper-
ating circuit, so if less than 15 seconds has passed since
the engine was stopped, when the starting switch is turned
to the ON position even when the engine is stopped, it is
possible to operate
the levers to lower the work equipment to the ground.
In addition, this operation can also be used to release the
remaining pressure in the hydraulic cylinder circuit or to
lower the boom after the machine has been loaded onto a
trailer.
