To mount the bucket to the linkage, proceed as follows:
1. Make sure that the machine and the bucket stand both
onto a hard and level ground. The bucket should stand
on its bottom side.
2. Place the O-ring seals onto the inner bosses of the
bucket.
3. Position the machine close to the bucket, and gently
operate the boom and arm controls in order to align the
arm top between the respective bosses on the bucket.
4. Place the gate lock lever in central position, stop the
engine and remove the starter key.
5. Position the mounting spacers if required. Place a
punch on the flat edge of the pin (2), and push it in
using a hammer.
NOTICE: Make sure to insert the pin by its chamfered
edge. Make sure to insert the pin from the bucket side
opposite to the locking boss.
6. Push the pin until the locking hole on the pin is aligned
to the locking hole on the bucket boss. Install either
the retaining pin or the locking bolt.
7. Get into the cab, start the engine and place the gate
lock lever in the forward position.
8. Gently extend the bucket cylinder to align the bucket
connecting rod between the respective bosses on the
bucket.

engine and remove the starter key.
10. Insert the pin (1) and lock it as described for the pin
(2).
