Operation
Work Levers (Joysticks) (ISO Style)
NOTE: When starting work, move joysticks slowly and check
movement of swing and front attachment and dozer
(outrigger).
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 54 and Figure 56)
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. In some cases while swinging or moving,
the relief valves may make some noise. This is
normal and does not affect the performance of the
equipment.
Right-hand Work Lever (Joystick) (Figure 54 and Figure 56)
5. Boom down
6. Boom up
7. Bucket crowd
8. Bucket dump
NOTE: Even after stopping the engine, the front can be
lowered to the ground by operating joystick. Set
safety lever on "UNLOCK" position and turn starter
switch "ON".
WARNING!
Check surrounding area before swinging. When operating a
lever while in auto idle, do it carefully, because the engine
speed will increase rapidly
