•
Never exceed the maximum lifting capacity of the crane and be aware of potential weight
shifts due to moving load. A load swinging or suddenly jerking at the chain may lead to a tem-
porary increases in weight. This in turn might cause the crane or load to be damaged and can
even be the cause of severe injuries.
•
Maintenance has to be performed regularly in order to guarantee the secure and correct func-
tion of the device. It, however, should only be performed by specially trained personnel. In
case of questions please contact the producer or an authorised service partner.
•
Please note that this product is not suited for lifting aircraft engines or other aircraft parts.
•
Do not try to move the crane while it is carrying weight with its boom in a raised position as
this shift in weight greatly increases risk of the crane tipping over.
•
Only use the crane on even ground capable of withstanding the weight in order to avoid cave-
ins and inadvertent rolling. This at the same times minimises the swinging of the load, which in
turn minimises the risk of injury.
•
Make sure that no one else is standing in the path of the crane when moving the same.
