Safety Alert Symbol and Headline Notations
In this manual, the following safety alert symbol and
signal words are used to alert the reader to the potential
for personal injury of machine damage.
dThis is the safety alert symbol. When you see this
symbol, be alert to the potential for personal injury.
Never fail to follow the safety instructions prescribed
along with the safety alert symbol.
The safety alert symbol is also used to draw attention to
component/part weights.
To avoid injury and damage, be sure to use appropriate
lifting techniques and equipment when lifting heavy
parts.
dCAUTION:
Indicated potentially hazardous situation which could, if
not avoided, result in personal injury or death.
IMPORTANT:
Indicates a situation which, if not conformed to the
instructions, could result in damage to the machine.
fNOTE:
Indicates supplementary technical information.

Variable turbo controller. VGS is an exhaust turbo charged
system to supercharge the exhaust energy while running
the engine at slow idle speed. VGS optimizes the turbine
rotation, improves the performance at slow-speed torque
and the acceleration, reduces fuel consumption, and reduces
particulate matter (PM) by adjusting the nozzle opening of
turbine housing.

Name Explanation
DPF Diesel Particulate Filter DPF is a filter which removes particulate matter (PM)
including the toxic substance of exhaust gas of the diesel
engine. Exhaust particulate removal equipment.
DPD Diesel Particulate Diffuser DPD is an exhaust emission control system, a type of DPF,
which cleans up particulate matter (PM) of diesel engine
exhaust gas. DPD is a ceramic filter which traps and filters
PM of exhaust gas. DPD burns up accumulated PM when PM
increases and regenerates the filter.
DOC Diesel Oxidation Catalyst Oxidation catalyst for the diesel engine. Diesel oxidation
catalyst oxidizes unburnt fuel and raises exhaust
temperature.
CSF Catalyzed Soot Filter Filter. The filter traps, burns, and remove particulate matter
(PM) by using high-temperature-exhaust gas with diesel
oxidation catalyst. Catalyst is applied onto the filter. This
advances PM burning.
PM Particulate Matter Particulate matter in gas
EGR Exhaust Gas Recirculation The EGR control re-circulates a part of exhaust gas in the
intake manifold and combines it with intake-air. Therefore,
combustion temperature is lowered and generation of oxide
of nitrogen (NOx) is controlled.
