3. RIGHT WORK EQUIPMENT CONTROL LEVER
(with auto-deceleration device)
WARNING
If an lever is operated when in the deceleration range, the
engine speed will suddenly increase, so be careful when
operating the levers.
This lever is used to operate the boom and bucket.
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 (5), 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).
