4 - OPERATING INSTRUCTIONS
Normal operation of the machine
When rolling in the arm, the roll-in movement stops mo-
mentary at point
(X)
as shown, then recovers speed again
after passing point
(X)
.
The reason is that the movement by the arm weight is
faster than the speed of oil flow into the cylinder. When
lowering the boom, a sound may be heard continuously.
This is caused by the oil flow in the valve.
If the machine is overloaded, a sound is caused by the
relief valves, which protect the hydraulic systems.
NOTICE:
do not exceed the machine performance. It may
result in accident or failure.
NOTICE:
perform lifting operations within the specified
load limit.
The upper-structure swings when the left control lever
is moved rightward or leftward. The swinging speed is
determined by the stroke of the lever.
• When moving the left control lever leftward, the upper-
structure swings leftward.
• When moving the left control lever rightward, the upper-
structure swings rightward.
• When returning the left control lever centrally (neutral
position) the upper-structure stops moving.
When you stop swinging the machine, a noise near the
swing motor may be heard. The noise is generated by
the brake valve.
