RETRACTING THE SIDE FRAME

WARNING: Do not loosen side frame guide, bolts (2)
IMPORTANT: Remove and clean mud and gravel from con-
tact area of track frame (3) and side frame (4)
using compressed air.
Required Tools: Power Boost Wrench (including accessories)
Torque Wrench (width across flats: 50 mm)
Air Compressor (slide surface cleaning)
1. Remove twenty two mounting bolts (1) (11 used for each
side) from the retracting side frames.
2. Retracting Side Frame (Track Gauge)
Turn the boom mode switch OFF so that the machine can
be raised off the ground with front attachment.
3. Raise track (6) to be retracted using the front attachment,
as illustrated.
Slowly rotate raised track (6) back and forth. The side
frame will be retracted with its own weight and stop
when it comes into contact with guide (2).
IMPORTANT: Maintain a 90 to 110° angle; never make an
acute angle between the boom and the arm.
If side frame (4) does not retract completely, lower the un-
dercarriage and turn the upperstructure 180°. Raise the op-
posite side track about 15° from the ground using the front
attachment. Slowly push the arm out, to retract side frame
(4).
IMPORTANT: Do not raise track (6) excessively high or op-
erate the arm-control lever abruptly. Dam-
age to the track frame may result.
4. Slowly lower track (6) to the ground. Tighten eight
mounting bolts (5) (4 used for each side) to the specifica-
tion.
Tightening Torque: 2800 N•m (280 kgf•m, 2025 lbf•ft)
5. Retract the opposite side, following procedures 1 to 4
above.
