OPERATION

WORK EQUIPMENT CONTROLS AND OPERATIONS

If the lever is operated when the engine speed has been lowered by the auto-deceleration function, the engine speed will
suddenly rise, so operate the levers carefully.
Use the control levers to operate the work equipment.
Note that when the levers are released, they return to the HOLD position and the work equipment is held in that
position.
If the work equipment control levers are returned to the neutral 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.
REMARK
With this machine, an accumulator is installed in the operating circuit, if less than 15 seconds has passed since the
engine was stopped, when the starting switch is turned to the ON position even with the engine stopped, it is
possible to operate the levers to lower 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.

operate the arm.
Swing control

swing the upper structure.
