Safety rules
2-15
Ventilation for enclosed areas 0.
Exhaust fumes from the engine can kill.
If it is necessary to start the engine within an enclosed area, or
when handling fuel, flushing oil, or paint, open the doors and
windows to ensure that adequate ventilation is provided to pre-
vent gas poisoning.
Checking signalman’s signals and signs 0.
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 follow 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 0.
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 0.
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 opera-
tion.
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.
Gas, dust, and inflammable vapours 0.
Do not operate combustion engines in an environment that may contain inflammable gases or vapours. These
gases, dusts, or vapours may ignite or be sucked in by the suction system, thus causing a rise in engine speed or
an exceeding of the engine's maximum rpm. This may lead to a fire, an explosion, and major damage to property.
It may also happen that the engine cannot be switched off anymore.
Mirrors, windows and lighting 0.
Clean the windows and the headlights to ensure maximum sight.
Adjust the rear-view mirror in such a way that you have an excellent view of the rear from the driver's seat.
Keep the mirrors clean. See "Adjust rear view mirror on page 3-65".
Ensure that the complete lighting system operates properly and that it is correctly adjusted.
Immediately replace broken window panes by new ones.
