4. Wind two wire ropes (4) around the front and rear sec-
tions (one wire rope on each section) of the side frame.
Connect lever block (5) to the ends of each wire rope.
Attach soft protectors (6) between the side frame (3) cor-
ners and wire ropes (4) to prevent damage to side frame
(3) and wire ropes (4).
5. Wind two wire ropes (8) around the arm near the bracket
of bucket (7). Connect each rope ends to lever blocks (5).
Then, slowly extend the front attachment so that sag on
wire ropes is removed. Attach soft protectors (6) between
the bucket bracket corners and wire rope to prevent
damage to wire ropes.
6. Retracting Side Frame (Track Gauge)
Turn the boom mode switch OFF so that the machine can
be raised off the ground with front attachment.
7. While lowering the boom, raise the extending side frame
approx. 50 mm (2 in) above the ground. If the side frame
is raised too much, extending force increases.
8. Operate lever blocks (5) so that the rear (travel device
side) and front (front idler side) of the side frame is equal-
ly extended until side frame guide (9) comes in contact
with the track frame stopper.
WARNING: When the lever block becomes inoperable,
it is because too much resistance exists against the
extending force.
Avoid working by force. Otherwise, lever block and/or
wire rope may be damaged and/or fly away possibly
resulting in severe personal injury.
Stop the work and check if the front and rear of the
side frame are equally extended or if the side frame is
raised to the proper height.
Take corrective measures as necessary.
WARNING: After raising the side frame above the
ground, never operate the arm to extend the side
frame. If the arm is operated, the wire ropes are
pulled with excessive tension force. Damage to the
lever block or wire rope may result, possibly causing
severe personal injury.
9. When side frame guide (9) comes in contact with the
track frame stopper, install side frame tightening bolts (1)
(18 used) (9 used in two places) and tighten temporarily
by hand. In case it is difficult to tighten with hand, bolt
and screw hole centers may not be correctly aligned. Re-
align bolt and screw hole centers by operating the lever
blocks.
