k k
WARNING
• The tail of the machine extends outside the tracks.
Visually check safety around the machine before
swinging.
• When performing swing operation on a slope, the ma-
chine may lose its balance and turn over. Avoid such
operation as much as possible.
It is particularly dangerous to swing downhill when the
bucket is loaded.
If it is unavoidable to perform such operations, pre-
pare an embankment to make a platform (A) on the
slope so that the machine is horizontal.
Move L.H. work equipment control lever (1) to the right and left.
The upper structure swings.
(a) Swing RIGHT
The upper structure swings to the right.
(b) Swing LEFT
The upper structure swings to the left.
When you do not swing the upper structure, set L.H. work
equipment control lever (1) to NEUTRAL position (N).
REMARK
To swing upper structure on a slope, run the engine at low idle
and operate the work equipment control lever finely.
In particular, avoid the abrupt operation when bucket is loaded.
When bucket is loaded, the swing parking brake is released
and upper structure swings momentarily by operating the L.H.
work equipment control lever, but it is not a trouble.
