VISIBILITY FROM OPERATOR'S SEAT
The visibility of this machine required by visibility standards (ISO 5006) are shown in the drawing below.
Proximity visibility
The figure below shows a visibility from the machine at a spot 1.0m (3 ft 3 in) away from outside the machine
and 1.5m (4 ft 11 in) above the ground. Shaded area (A) in the figure shows an area whose view is blocked by a
part of the machine when the machine is equipped with the mirrors and other visibility assistant devices. Be fully
aware that there is an area where the operator cannot see when operating the machine.
12m radius visibility
The figure below shows a visibility from the machine for a radius of 12m (39 ft 4 in). Shaded area (B) in the
figure shows an area whose view is blocked by a part of the machine when the machine is equipped with the
mirrors and other visibility assistant devices. Be fully aware that there is an area where the operator cannot see

ACTIONS TAKEN TO MEET EXHAUST GAS REGULA-
TIONS
This machine conforms to either regulation of Tier4 Final (North America) or Stage IV (Europe).
This machine is equipped with the following two exhaust gas treatment systems:
• Komatsu Diesel Particulate Filter (hereafter KDPF): A device which captures soot in the exhaust gas to pu-
rify exhaust gas. This process performs the combustion of soot referred to as "regeneration".
• Urea SCR system: A device which decomposes the toxic nitrogen oxides (NOx) mixed in the exhaust gas
into harmless nitrogen and water. Spraying aqueous urea solution into the exhaust gas produces a reaction
between the nitrogen oxides and ammonia generated from the urea solution and decomposes the nitrogen
oxides into nitrogen and water.
Either AdBlue® or DEF may be used as the aqueous urea solution for the SCR system.
AdBlue® is a registered trade-mark of VDA (Verband der Automobilindustrie e.V.: Automobile Association of
Germany).
DEF is the abbreviation for Diesel Exhaust Fluid.
Commercial DEF that is API approved and meets all the requirements defined in ISO 22241-1.
This solution will be represented as AdBlue/DEF throughout this manual.
About AdBlue/DEF
AdBlue/DEF is necessary for the urea SCR system. AdBlue/DEF is a colorless transparent 32.5% aqueous urea
solution. Urea as main constituent is a material which is used for cosmetics, medical and pharmaceutical prod-
ucts, and fertilizer, etc.
If you add any additional additive agents or water to AdBlue/DEF and use it, the devices will not function proper-
ly, and conformance to the exhaust gas regulations will be lost. In addition, it will cause failure of the machine.
• In Europe, use AdBlue.
• In North America, use DEF (Diesel Exhaust Fluid) which is certified by API (American Petroleum Institute).
The certified DEF has the API DEF Certification Mark shown as follows. Look for the API DEF Certification
Mark when purchasing DEF.
API Diesel Exhaust Fluid Certification Mark is the trade
mark of API (American Petroleum Institute).

WARNING
Be sure that you fully understand the correct position, content and how to avoid a danger shown in the
safety labels.
Handle the warning signs and safety labels used on this machine as follows.
• Always keep the safety labels clean so that you can read it properly. When cleaning the safety labels, do
not use organic solvents or gasoline. These may cause the labels to peel off.
• If the safety labels are damaged, lost, or cannot be read properly, replace them with new ones. For details
of the part numbers for the safety labels, see this manual or the actual label, and place an order to your
Komatsu distributor.
• There are also other labels in addition to the warning signs and safety labels. Handle those labels in the
same way.
