OPERATION OF WORK EQUIPMENT

If any lever is operated when in the deceleration range, the
engine speed will suddenly increase, so be careful when
operating the levers.
The work equipment is operated by the left and right work equip-
ment control levers. The left work equipment control lever oper-
ates the arm and swing, and the right work equipment control
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 equip-
ment is held in place.
If the work equipment control lever is returned to the neutral
G
position when the machine is stopped, even if the fuel control
dial is set to FULL, the auto-deceleration mechanism will act
to reduce the engine speed to a mid-range speed.
If the levers are operated within 15 seconds after stopping the
G
engine, it's possible to lower the work equipment to the
ground. In addition, the levers can also be operated to
release any remaining pressure inside the hydraulic cylinder
circuit and to lower the boom after loading the machine on a
trailer.
