SAFETY
ATTACHMENT INSTALLATION
When installing optional parts or attachments, there may be problems with safety or legal restrictions. Therefore
contact your Komatsu distributor for advice.
Any injuries, accidents, product failures or other property damages resulting from the use of unauthorized
attachments or parts will not be the responsibility of Komatsu.
When installing and using optional attachments, read the instruction manual for the attachment, and the general
information related to attachments in this manual.
ATTACHMENT COMBINATIONS
Depending on the type or combination of work equipment, there is a hazard that the work equipment may hit the cab
or other parts of the machine. Before using unfamiliar work equipment, check if there is any hazard of interference,
and operate with caution.
CAB WINDOW GLASSES
If the cab glass on the work equipment side is broken, there is a hazard that the work equipment may contact the
operator's body directly. Stop operation immediately and replace the glass.
The ceiling window is made of organic glass (polycarbonate), and as such it is apt to break easily when receiving
damage on the surface, thereby deteriorating its protective characteristic. If there is a crack or damage caused
by a fallen rock, or when any sign of them is noticed, replace it with a new window.
If the cab door does not open for any reason, remove the glass from the rear window and use the window as an
emergency escape exit.
For details, see "EMERGENCY EXIT FROM OPERATOR'S CAB (PAGE 3-44)" in this manual.
UNAUTHORIZED MODIFICATIONS
Any modification made without authorization from Komatsu can create hazards. Before making a modification,
consult your Komatsu distributor.
Komatsu will not be responsible for any injuries, accidents, product failures or other property damages resulting
from modifications made without authorization from Komatsu.
SAFETY AT JOBSITE
Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous.
When carrying out operations near combustible materials such as thatched roofs, dry leaves or dry grass, there
is a hazard of fire, so be careful when operating.
Check the terrain and condition of the ground at the worksite, and determine the safest method of operation. Do
not operate where there is a hazard of landslides or falling rocks.
If water lines, gas lines, or high-voltage electrical lines may be
buried under the worksite, contact each utility and identify their
locations. Be careful not to sever or damage any of these lines.
Take necessary measures to prevent any unauthorized person
from entering the operating area.
If any fire is lit near the machine, there is danger that sparks will
be sucked in and cause a fire.
Be extremely careful when handling flames.
When traveling or operating in shallow water or on soft ground, check the shape and condition of the bedrock, and
the depth and speed of flow of the water before starting operations.
