GENERAL PRECAUTIONS COMMON TO OPERATION AND MAINTE-
NANCE
During the aftertreatment devices regeneration, avoid getting near the exhaust pipe outlet and around the after-
treatment devices to prevent being burnt. Also, keep combustible materials away from the exhaust pipe outlet
and around the aftertreatment devices to prevent a fire.
When there are thatched houses, dry leaves or pieces of paper near the job site, stop the regeneration before
starting the work in order to prevent fire hazards due to highly heated exhaust gas during the aftertreatment de-
vices regeneration.
Explosion caused by lighting equipment
• When checking fuel, oil, battery electrolyte, or coolant, always use lighting with anti-explosion specifica-
tions.
• When taking the electrical power for the lighting equipment from the machine, see “POWER SUPPLY OUT-
LET (3-106)”.

contact (both feet and one hand, or both hands and one
foot) with the handrails and steps to ensure that you sup-
