READ THE INSTRUCTION MANUAL THOROUGHLY 6
q
Before installing or using any attachment or option, make sure that you thoroughly read and understand the
instruction manuals for the machine and the attachment or option.

If you lose the instruction manual or it is damaged, always obtain an new copy from the attachment manufac-
turer or your Komatsu distributor.
PRECAUTIONS WHEN REMOVING OR INSTALLING 6
When removing or installing the attachment or option, obey the following precautions, and take care to ensure
safety during the operation.
q
Carry out the removal and installation operation on a flat, firm ground surface.
q
When the operation is carried out by two or more workers, choose the leader and follow his instructions.
q
Use a crane when handling heavy objects (more than 25 kg). (The crane must be operated by a qualified
operator.)
q
Never go under a load raised by the crane.
q
Do not carry out operations with the load kept raised by the crane. Always use a stand to prevent the load
from falling.

When removing a heavy part, consider the balance after it is removed. To prevent the machine from tipping
over, set a support in position if necessary before removing the part.

over.
