8. PRECAUTIONS FOR MAINTENANCE
USE OF LIGHTING
• When checking fuel, oil, or battery electrolyte, always use lighting with anti-explosion specifications.
If such lighting equipment is not used, there is danger of explosion.
• If work is carried out in dark places without installing lighting, there is danger of injury, so always install
proper lighting.
• Even if it is dark, do not use a lighter or flame instead of lighting. There is danger of starting a fire and if the
battery gas ignites it may cause an explosion.
• When using the machine as the power supply for the lighting, follow the instructions in this Operation and
Maintenance Manual.
PREVENTION OF FIRE
There is danger of the fuel and battery gas catching fire during maintenance, so always follow the precautions
below when carrying out maintenance.
• Store fuel, oil, grease and other flammable materials away from flame.
• Use non-flammable materials as the flushing oil for cleaning parts. Do not use diesel oil or gasoline. There is
danger that they will catch fire.
• Never smoke when carrying out inspection or maintenance. Always smoke in the prescribed place.
• When checking fuel, oil, or battery electrolyte, always use lighting with anti-explosion specifications. Never
use lighters of matches as lighting.
• When carrying out grinding or welding operations on the chassis, remove any inflammable materials to a
safe place.
• Be sure that a fire extinguisher is present at the inspection and maintenance point.
