OPERATIONS OPERATION OF WORK EQUIPMENT WARNING ●
For machine with auto-deceleration device, if any lever is operated when in deceleration range, the engine speed will suddenly increase, so be careful when operating the levers.
●
If work equipment control levers are jerked, the engine speed will suddenly increase, so be careful when operating the levers.
The work equipment is operated by left and right control levers, and the bottom dump switches. The LEFT work equipment control lever controls SWING, ARM and bottom dump closing. The RIGHT work equipment control lever controls BOOM, BUCKET and bottom dump opening. The levers and switches, and movement of the work equipment are as shown in the diagrams. If the levers and switches are released, they will return to the NEUTRAL position, and the work equipment will be held in position. ● If the work equipment control lever is returned to the neutral position when the machine is stopped, even if the fuel control lever is set to FULL, the auto-deceleration mechanism will act to reduce the engine speed to a mid-range speed (for the machine with auto-deceleration device). REMARK If the levers are operated within 15 seconds after stopping the engine, it is 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. Arm operation
