Work Levers (Joysticks) (ISO Pattern)
NOTE: When starting work, move work levers (joysticks)
slowly and check movement of swing and front
attachment.
This equipment is manufactured u
sing 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 stopped.
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 can cause
it to move faster than the amount of oil being
supplied.
