OPERATION OF WORK EQUIPMENT
WARNING
If any lever is operated when the engine is at auto decelera-
tion speed, 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
position for 4 seconds, even if the fuel control dial is set to
FULL, the auto-deceleration mechanism will act to reduce the
engine speed to auto-decel speed.
● If the levers are operated within 15 seconds after the engine
stops, 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.
NOTE: This is only possible if the key is returned to the "On"
position after the engine is stopped.
