Do not use the automatic locking of the locking pins at a height of over one metre.
If the locking pins do not return to the normal position when the front plate is tilted, do
not raise the attachment any more. Lower the attachment on the ground and secure
the locking manually.
The automatic return of the locking pins is a useful feature, when mounting an empty attachment to the
loader. In other cases we recommend that you lock the pins manually.

Connecting and disconnecting the hydraulic fittings
The two hydraulic fittings of the telescopic boom are connected to corresponding fittings on the loader.
Before connecting or disconnecting hydraulic fittings, shut down the loader engine and move the auxiliary
hydraulics lever on the loader to its extreme positions a few times. This way, there will be no remaining
pressure in the system and the fittings are easy to connect.
To connect and disconnect the fittings, move the collar at the end of the female fitting. The hoses should be
connected so that the fittings with coloured caps are connected. This way the auxiliary hydraulics control
lever will move the grapple the same way every time the telescopic boom is used.
When removing the attachment, always disconnect the hydraulic fittings before
detaching the quick attach plate, to prevent hose damage and any oil spills. Reinstall
the protective caps on the fittings to prevent impurities from entering the hydraulic
system.
Never connect or disconnect quick couplings or other hydraulic components while the
system is under pressure. High-pressure fluid ejection may cause injuries.
Keep the fittings as clean as possible; use the protective caps for the quick couplings on both the
attachment and the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Note that the
protective caps on the loader and the attachment can be fastened to each other during operation to reduce
the accumulation of dirt. Never leave the hoses hanging on the ground; place them on top of the equipment.

Jib boom operation
•
Before use check that the lifting hook is intact and that its safety latch is in good condition. Do not
use damaged equipment.
•
Use only lifting equipment that are approved for lifting and strong enough for the task. The lifting
rope should have a rated capacity of at least twice the load. Normal load securing straps are usually
not approved for lifting work.
•
Do not tie the lifting ropes. Use suitable hooks or links.
•
Plan the lifting work ahead, avoid hanging the load unnecessarily.
•
Ensure that the loader and the attachment are used in a safe manner and as intended.
•
Ensure that the ground surface is level and solid enough for safe lifting.
•
Operate the attachment only from the driver's seat.
Do not reverse with the loader while simultaneously dragging load. Make sure that the
loader can handle the load being lifted. When lifting load from a high level, the loader
could tip forward when reversing with the loader.
