Stop un-winding the hook block when it reaches the ground, otherwise, it may result in irregular
winding of the wire rope to the drum. Once the hook block reaches the ground, avoid
un-winding any more.
Use the following procedure to remove the wire rope.
1. Station the machine on a level and solid ground and set it to a
posture with minimum boom length and 20 degrees of the angle.
2. At the posture as 1. above, un-wind the hook block until it nearly
touches the ground.
3. Operate the right work equipment control lever in the BOOM
LOWER position (push it toward outside) to lower the hook block
on the ground.
4. Remove the mounting bolt (1) and pull out the wire socket pin (2), and then remove the wire socket (3).
5. Remove the wire clip (4).
6. Pull out the wire rope (5) of the wire socket (3), following the
procedure provided below.
(1) Bring a 6 to 10 mm round bar (A) into contact with the rope
wedge (6).
(2) Remove the rope wedge (6), lightly tapping the round bar (A)
with a hammer in the direction indicated by the arrow (a).
7. Remove the wire rope (5) from the weight (8) of the over hoist
detector and the hook block (7).
