Page 40: Replace Rubber Hoses Periodically
SAFETY Replace Rubber Hoses Periodically  Rubber hoses that contain flammable fluids under pressure may break due to aging, fatigue, and abrasion. It is very difficult to gauge the extent of deterioration due to aging, fatigue, and abrasion of rubber hoses by inspection alone.
Page 41: Prevent Fires
SAFETY Prevent Fires Check for Oil Leaks:  Fuel, hydraulic oil and lubricant leaks can lead to fires.  Check for oil leaks due to missing or loose clamps, kinked hoses, lines or hoses that rub against each other, damage to the oil-cooler, and loose oil-cooler flange bolts.
Page 42: Evacuating In Case Of Fire
SAFETY Check Key Switch:  If a fire breaks out, failure to stop the engine will escalate the fire, hampering fire fighting. Always check key switch function before operating the machine every day: 1. Start the engine and run it at low idle. 2.
Page 43: Beware Of Exhaust Fumes
SAFETY Beware of Exhaust Fumes  Prevent asphyxiation. Engine exhaust fumes can cause sickness or death.  If you must operate in a building, be sure there is adequate ventilation. Either use an exhaust pipe extension to remove the exhaust fumes or open doors and windows to bring enough outside air into the area.
Page 44: Avoid Applying Heat To Lines Containing Flammable Fluids
SAFETY Avoid Applying Heat to Lines Containing Flammable Fluids  Do not weld or flame cut pipes or tubes that contain flammable fluids.  Clean them thoroughly with nonflammable solvent before welding or flame cutting them.

Page 95: Aftertreatment Device Regeneration
OPERATOR'S STATION Aftertreatment Device Regeneration To keep the system working correctly, periodically, the collected deposit is removed by purging it at a high temperature. This process is known as "regeneration". The regeneration is done in three ways; automatic regeneration (abbreviated as auto-regeneration), manual regeneration, and service regeneration.
Page 96: Automatic Regeneration (Auto-Regeneration)
OPERATOR'S STATION Automatic Regeneration (Auto-Regeneration) The machine automatically increases the exhaust temperature during normal operation to purge the deposit. There are no actions on the part of the operator when auto-regeneration is performed.  Auto-regeneration may start while operating the machine, and there is no need to stop the machine when this happens.
Page 97: Manual Regeneration
OPERATOR'S STATION Manual Regeneration When the deposit level increases to a level that is more than an auto-regeneration can remove, a manual regeneration is required. The yellow regeneration symbol (shown below)(1) and service indicator (2) appear to make the operator aware that this is required.
