GENERAL PRECAUTIONS

PRECAUTIONS RELATED TO SAFETY

If attachments or options other than those authorized by Komatsu are installed, this will not only affect the life of the machine, but will also cause problems with safety.

When installing attachments not listed in this Operation and Maintenance Manual, please contact your Komatsu distributor first.

If you do not contact Komatsu, we cannot accept any responsibility for any accident or failure.

WARNING

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 out the 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), 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 centre 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 unqualified person. For details of the removal and installation operations, please contact your Komatsu distributor.

PRECAUTIONS WHEN INSTALLING ATTACHMENTS

WARNING

Long work equipment reduces the stability of the chassis, so if the swing is operated on a slope, or when going down a steep hill, the machine may lose its balance and overturn. The following operations are particularly dangerous, so never operate the machine in these ways.

Going downhill with the work equipment raised

Traveling across slopes

Swinging the upper structure on slopes If heavy work equipment is installed, the overrun of the swing becomes greater (the distance from the point where the operator operates the control levers to stop the swing to the point where the upper structure stops completely), so there is danger of mistaking the distance and hitting something. Always operate so that there is an ample margin to the stopping point. Furthermore, the hydraulic drift also becomes larger when the work equipment is stopped in mid-air, it will gradually move down under its own weight). Always follow the correct procedure when installing the boom and arm. If the correct procedure is not followed, this may lead to serious damage or injury, so please consult your Komatsu distributor before carrying out installation.

If long work equipment is installed, the working range will suddenly become larger, so there is danger of mistaking the distance and hitting something. Always operate the work equipment so that there is ample space from any obstacles in the area INCORRECT CORRECT
