PRECAUTIONS FOR USING ATTACHMENT AND OPTIONS
PRECAUTIONS FOR USING ATTACHMENT AND OPTIONS
Install only attachments or options authorized by Komatsu. Komatsu cannot accept any responsibility
for any not authorized by Komatsu. Any personal injury, failure, or property damage caused by the use
of unauthorized attachments or options will not be the responsibility of Komatsu.
When installing attachments or options to the machine, it is necessary to pay attention to safety. Observe the
following precautions strictly when selecting, installing or removing, or using attachments or options.
PRECAUTIONS WHEN SELECTING
Consult your Komatsu distributor before installing attachments or options to the machine. Depending on the
type of attachment or option, it may be necessary to install a front guard, overhead guard, or other safety struc-
ture to the machine. There may also be problems of the attachment or option hitting the operator's cab.
READ THE OPERATION AND MAINTENANCE MANUAL THOROUGHLY
Before installing or using any attachment or option, make sure that you thoroughly read and understand the in-
struction manuals for the machine and the attachment or option.
If you lose the instruction manual or it is damaged, obtain a new copy from the attachment manufacturer or your
Komatsu distributor.
PRECAUTIONS WHEN REMOVING AND INSTALLING
When removing or installing the attachment or option, observe the following precautions, and take care to en-
sure safety during the operation.
•
Perform the removal and installation operation on a level and firm ground surface.
•
When the operation is performed by 2 or more workers, choose the leader and follow his/her instructions.
•
Use a crane when handling heavy objects (25 kg or more).
(The crane must be operated by a qualified operator.)
•
Never go under a load raised by the crane.
•
Do not perform 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 machine balance after it is removed. To prevent the machine
from tipping over, set a support in position if necessary before removing the part.
•
Before installing or after removing the attachment or option, set it in a stable condition to prevent it from
falling over.
•
For details of the removal or installation operation, consult your Komatsu distributor.
PRECAUTIONS WHEN USING
When long or heavy work equipment is installed, remember the following precautions. Before starting opera-
tions, move the machine to a safe place and perform a test operation to make sure that you fully understand the
movement, center of gravity, and working range of the machine.
•
Do not perform the swing operation if the machine is at an angle. If the swing is performed with the machine
at an angle, there is a danger that the machine may tip over.
•
Always maintain a safe distance from obstacles in the surrounding area when operating the machine. If
long work equipment is installed, the working range becomes larger.
•
If heavy work equipment is installed, pay attention to the following precautions.
•
The swing overrun (the distance the work equipment moves before completely stopping after the swing
brake is applied) will be greater. There is a danger of hitting objects if the swing overrun is miscalculat-
ed, so allow extra space to the position you want to stop swinging when performing the swing.
