G: OPERATION OF THE WORKING EQUIPMENT 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 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 HOLD position and the work equipment is held in place. l If the work equipment control lever is returned to HOLD 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.
A If any lever is operated when in the deceleration range, the engine speed will suddenly increase, so be careful when operating the levers. * 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.
