2.2 General precautions
Checking signalman's signals and signs
Set up signs to inform of road shoulders and soft ground. If
the visibility is not good, position a signalman if necessary.
Operators should pay careful attention to the signs and fol-
low the instructions from the signalman.
Only one signalman should give signals.
Make sure that all workers understand the meaning of all
signals and signs before starting work.
Emergency exit from operator's cab
Machines equipped with a cab have doors on the left and right
sides. If the door on the one side does not open, escape from
the door on the other side.
Be careful about asbestos dust
Asbestos dust in the air can cause lung cancer if it is inhaled.
There is danger of inhaling asbestos when working on jobsites
handling demolition work or work handling industrial waste.
Always observe the following.
Spray water to keep down the dust when cleaning. Do not
use compressed air for cleaning.
If there is danger that there may be asbestos dust in the air,
always operate the machine from an upwind position. All
workers should use an approved respirator.
Do not allow other persons to approach during the operation.
Always observe the rules and regulations for the work site
and environmental standards.
This machine does not use asbestos, but there is a danger that
imitation parts may contain asbestos, so always use genuine
KOMATSU parts.
