ATTACHMENTS AND OPTIONS
Precautions for removal and installation operations
When removing or installing the attachment, always do as follows to ensure safety in the operation.
Carry out the removal and installation operation on firm, level ground.
When carrying out the operation with two or more workers, determine the signals and follow these
during the operation.
Always use a crane when you lift or carrying heavy objects (more than 25kg or 55 lb).
When removing heavy components, always support the component before removing it.
When lifting with a crane, be particularly careful about the position of the center of gravity.
It is dangerous to carry out operations with a load left raised by a crane. Always prepare a stand and
ensure that the condition is safe.
When leaving an attachment removed or when installing the attachment, make sure that it is in a sta-
ble condition and cannot fall over.
Never go under a load raised by a crane.
Stay in a safe place where there is no danger if the load should fall.
NOTICE
Qualifications are required to operate a crane. Never allow the crane to be operated by an unqualified per-
son.
For details of removal and installation operations, contact your Komatsu distributor.
