WARNING
• Never push a load along the ground, or
the vehicle's load space, with the
extension boom. This can cause damage
to the boom system. This will lead to
expensive repairs.
• Never use the extension boom as a jack.
This could damage the slewing bearings
and the connection between the crane
column and the crane base.
• Always lift the load from the ground before
you start to slew. Do not tow the load over
the ground. This can damage the boom
system.
• If you are working with loads in restricted
spaces (for example, windows):
Check that the boom system can move up
and down freely.
The boom system will bend somewhat,
when loading and unloading the crane.
• If the boom system is in a high position
(first boom above 70°), do not allow the
boom to lower at full speed. The crane
could go into an uncontrolled movement.
Be careful if, in particular, the OLP gives
an early warning!
• When loading the vehicle:
Take the load off the stabiliser legs by
withdrawing them slightly. The stabiliser
legs must remain in light contact with the
ground.
CAUTION
• Operate the crane using smooth and gentle lever movements.
• If a cylinder is at its end position, free the operating lever. Otherwise overheating
can occur.
