PRECAUTIONS FOR OPERATING WITH THE OFF-
SET FUNCTION
CAUTION: Never jack up the machine with the front
in the offset position. This is extremely dangerous, as
the machine is unstable.
IMPORTANT: • Never use a hydraulic breaker when the
front is in the offset position, as this will
damage the lower and upper booms.
• Do not perform heavy duty work, or dig
gravel with the front in the offset position.
Do not perform tamping work with a
slope-finishing bucket attached.
These operation will damage the lower
and upper booms.
1. When digging with the front in the offset position, the
bucket will come in contact with the track link if the arm
is crowded.
Even if bucket does not touch the track link, watch for the
bucket digging under the track, as this will cause instabil-
ity.
2. Be sure to follow the precautions shown below.
(1) Do not use the 2.26 m (7' 5") arm and 2.81 m (9' 3")
arm as it will interfere with the cab when in the offset
position.
(2) Do not use the bucket as a pile driver with the boom
in the offset position.
(3) When digging with the boom in offset position, be
careful not to damage the cylinder stay.
3. In order to prevent the offset pins from getting rusty, op-
erate the offset function regularly. Check offset function
operation every time before starting work.
