Operation
Work Levers (Joysticks) (ISO Style)
NOTE: When starting work, move work levers (joysticks)
slowly and check movement of swing and front
attachment.
This equipment is manufactured using the lever configuration
described in ISO standards. Do not change valving, hoses, etc.,
that would change this standard. The boom, arm and bucket
movements and swing direction of work levers
(joysticks) are as
follows:
Left-hand Work Lever (Joystick) (Figure 44 and Figure 45)
1. Arm dump
2. Arm crowd
3. Left swing
4. Right swing
NOTE: The swing brake is spring applied and
hydraulically released. It is always engaged
when the work lever (joystick) is in "NEUTRAL"
or the engine is shut down.
NOTE: The following is not a mechanical malfunction
but a proper phenomenon of the excavator.
When operating the arm, it may stop
momentarily. When the arm is operated, the
weight of the arm may cause it to move faster
than the amount of oil being supplied.

WARNING!
Check surrounding area before swinging. When operating a
lever while in auto idle, do it carefully, because the engine
speed will increase rapidly.
