5.1. Mounting the jib boom to the loader
If your machine is equipped with a hydraulic locking system, refer to the relevant manuals for
additional mounting and safety instructions.
Mounting the jib boom to the loader is quick and easy, but it must be done carefully. An attachment that has
not been locked may come off the loader and cause hazardous situations. In the worst case, the attachment
may slide onto the driver along a raised boom. For this reason, the attachment must under no circumstances
be raised over one metre when it has not been locked. To prevent hazardous situations, always follow the
attachment mounting instructions provided in the following pages. Also remember the safety instructions in
Section 3 and the instructions provided in the loader manual.
The attachment is mounted to the loader boom by using the quick attach plate and the counterpart on the
attachment. The locking is semi-automatic; when the boom front plate is tilted towards the loader, the
locking pins are released as they hit the pin guides. The attachments are mounted to the loader as follows:
Never move or raise an attachment that has not been locked.
Step 1:
•
Lift the quick attach plate locking pin / locking pins up and turn them backwards
into the slot so that they are locked in the upper position.
•
Ensure that the hydraulic hoses are not in the way during installation.
Step 2:
•
Turn the quick attach plate hydraulically to an obliquely forward position.
•
Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can utilise this.
•
Depending on the storage position of the lift boom it may be necessary to assist
the mounting of the attachment by hand. Drive the loader of the boom to as
close as possible next to the attachment, and tilt the plate fairly to make it
easier to lift the digger on the plate.
Step 3:
•
Lift the boom slightly – pull the boom control lever backward to raise the
attachment off the ground.
•
Turn the boom control lever left to turn the bottom section of the quick attach
plate onto the attachment.
•
Turn the boom control lever further left so that the automatic locking of the
attachment triggers the locking pins.
Before moving or raising the attachment,
ensure that the locking pins are in the lower
position and come through the fasteners on
both sides. Unlocked attachment may fall on
the boom or operator and cause injuries.
