RIGHT WORK EQUIPMENT CONTROL LEVER (with auto-deceleration device) N ¤ WARNING If any lever is operated when in the deceleration range, the engine speed will suddenly increase, so be careful when oper- ating the levers. AM089570 This lever is used to operate the boom and bucket. Boom operation Bucket operation 1 RAISE 3 DUMP 2 LOWER 4 CURL N (Neutral) When the lever in this position, the boom and the bucket will be retained in the position in which they stop. For levers 2, 3 and 4, the engine speed changes as follows because of the auto-deceleration mechanism.
When the travel lever and work equipment control levers are at neutral, even if the fuel control dial is above the mid-range position, the engine speed will drop to a mid-range speed. If any of the levers are operated, the engine speed will rise to the speed set by the fuel control dial. If all control levers are set to neutral, the engine speed will drop by approx. 100 rpm, and after approx. 4 seconds, the engine speed will drop to the deceleration speed (approx. 1400 rpm). 2-21
