To remove the bucket from the linkage, proceed as
follows:
1. Operate the arm and bucket controls so that the arm
stands vertical and the bottom side of the bucket leans
against a hard and level ground.
NOTICE: never push the bucket onto the ground. The
bucket pins should be unloaded in order to be properly
extracted from the bushings.
2. Place the gate lock lever in central position, stop the
engine and remove the starter key.
3. Slide the O-ring seals onto the inner bosses of the
bucket.
4. Unlock the bucket pins by removing either the retain-
ing pins or the locking bolts. Check the locking tools
for wear or damage. Make sure to properly store the
locking tools to prevent damage.
5. Place a punch on the flat edge of the pin (1) , and push
it out using a hammer. Extract the pin (2) using the
same procedure. Make sure to properly handle and
store the bucket pins to prevent damage.

lock lever in the forward position.
7. Gently retract the bucket cylinder to release the bucket
connecting rod from the bucket hangers.

the arm top from the bucket hangers. Check the O-ring
seals and the mounting spacers for wear or damage.

mounting spacers to prevent damage.
NOTICE: If the bucket linkage does not easily come
out from the bucket hangers, lower the bucket to the
ground. In order to unstick the mating surfaces, gently
operate the bucket control to extend the bucket cylin-
der or the boom control to push down the arm top.
