Precautions for removal and installation operations
When removing or installing attachments, obey the following precautions and take care to ensure
safety during the operation.
Carry outthe removal and installation operations on a flat, firm ground surface.
When the operation is carried out by two or more workers, determine signals and follow these
during the operation.
When carrying heavy objects (more than 25 kg (55 lb)), use a crane.
When removing heavy parts, always support the part before removing it.
When lifting such heavy parts with a crane, always pay careful attention to the position of the
center of gravity.
It is dangerous to carry out operations with the load kept suspended. Always set the load on a
stand, and check that it is safe.
When removing or installing attachments, make sure that they are in a stable condition and will
not fall over.
Never go under a load suspended from a crane.
Always stand in a position that is safe even if the load should fall.
NOTICE
Qualifications are required to operate a crane. Never allow the crane to be operated by an
unqualified person.
