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, contact your Komatsu distribu-
tor first.
If you do not contact Komatsu, we cannot accept any responsibility for any accidents or failures.
WARNING
General precautions
● Attachments are strong tools. Handle them correctly to prevent serious injury.
● Read the operation manual for each attachment carefully, and do not use the machine before you
understand the operation method completely.
If you lose your operation manual, be sure to order another copy from the manufacturer or your
Komatsu distributor.
● Place your foot on a pedal only when necessary for prevention of serious injury caused by malfunc-
tion.
Precautions for removal and installation
When removing or installing an attachment, observe the following items and work safely.
● Install or remove an attachment on a level and hard place.
● When working by two persons or more in cooperation, decide signs and work according to them.
● When carrying a heavy part (25kg (55lb) or heavier), use a crane.
● When removing a heavy part, be sure to prepare a support for it in advance.
When removing it with a crane, take care of its center of gravity particularly.
● It is dangerous to work on a part lifted up with a crane. Be sure to place the part on a stand and check
safety.
● When leaving a attachment removed or installing it, place it in a stable position.
● Do not stand under a part lifted up with a crane.
Stay a place apart from the part where your are safe even if the part falls.
