ENGINE OIL RECOMMENDATIONS
AMBRA UNITEK CJ-4 ENGINE OIL (SAE 15W-40)
engine oil is recommended for use in your engine.
AMBRA UNITEK CJ-4 ENGINE OIL (SAE 15W-40)
engine oil will lubricate your engine correctly under
all operating conditions.
If AMBRA UNITEK CJ-4 ENGINE OIL (SAE 15W-40)
Multi-Viscosity Oil is not available, use only oil
meeting API engine oil service category CH-4
(preferred) or CG-4.
See the chart belo w for
recommended viscosity at
ambient air temperature
ranges.
NOTE: Do not put performance
additives or other oil additive
products in the engine
crankcase. The oil change
intervals given in this manual
are according to tests with
AMBRA UNITEK CJ-4 ENGINE
OIL (SAE 15W-40) lubricants.

DIESEL FUEL SYSTEM
Use No. 2 diesel fuel in the engine of this machine.
The use of other fuels can cause the loss of engine
power and high fuel consumption.
In very cold temperatures, a mixture of No. 1 and No.
2 diesel fuels is temporarily permitted. See the
following Note.
NOTE: See your fuel dealer for winter fuel
requirements in your area. If the temperature of the
fuel lowers below the cloud point (wax appearance
point), wax crystals in the fuel will restrict the fuel
filter and cause the engine to lose power or not start.
The diesel fuel used in this machine must meet the
specifications as shown below in, “Specifications for
Acceptable No. 2 Diesel Fuel”, or “Specification
D975-81” of the American Society for Testing and
Materials.
Fuel Storage
If you keep fuel in storage for a period of time, you
can get foreign material or water in the fuel storage
tank. Many engine problems are caused by water in
the fuel.
Keep the fuel storage tank outside and keep the fuel
as cool as possible. Remove water from the storage
container at regular periods of time.
Fill the fuel tank at the end of the daily operating
period to prevent condensation in the fuel tank.
Specifications for Acceptable No. 2 Diesel Fuel
API gravity, minimum ............................................................................................................................................. 34
Flash point, minimum ............................................................................................................................60°C (140°F)
Cloud point (wax appearance point), maximum ...........................................................-20°C (-5°F) See Note above
Pour point, maximum ..................................................................................................-26°C (-15°F) See Note above
Distillation temperature, 90% point ................................................................................282 to 338°C (540 to 640°F)
Viscosity, at 38°C (100°F)
Centistokes . ........................................................................................................................................ 2.0 to 4.3

What is Selective Catalytic Reduction (SCR)?
The main components of the SCR system include the
SCR catalyst, the Diesel Exhaust Fluid (DEF)/
AdBlue® injection unit, the DEF/AdBlue® tank, and
the DEF/AdBlue® dosing control unit.
How does Selective Catalytic Reduction
(SCR) work?
During combustion, harmful Nitrogen Oxide (NOx)
molecules are formed in the exhaust. By injecting a
DEF/AdBlue® solution into the exhaust prior to a
catalyst, the NOx can be converted to harmless
elemental Nitrogen and water. This happens when
the NOx molecules react inside the catalyst with the
heat generated by the engine and the ammonia in
the DEF/AdBlue® solution.
During cold engine operation at low engine coolant
and ambient air temperatures, water vapor will be
visible from the exhaust when the engine operates.
This water vapor will resemble steam or light white
smoke and will dissipate as the engine and machine
components warm and is considered normal.
NOTE: After engine shutdown, the SCR system will
perform a purge cycle, which permits the supply
module to continue to run for up to 70 seconds. This
is to be considered normal and requires no action
from the operator.
What is Diesel Exhaust Fluid
(DEF)/AdBlue®?
DEF/AdBlue® is a non-toxic aqueous urea solution (
32.5 %) with a slight ammonia odor used to
chemically reduce NOx emissions from heavy-duty
diesel powered vehicles.
DEF/AdBlue® is neither explosive nor harmful to the
environment and is classified under the minimum-risk
category of transportable fluids. DEF/AdBlue®
quality is defined by ISO 22241-1. The
American Petroleum Institute (API®) has a
voluntary certification program for DEF/AdBlue®. To
ensure DEF/ AdBlue® satisfies the requirements of
ISO 22241. DEF/AdBlue®. API Diesel Exhaust Fluid
Certification Mark is a registered trademark of API in
the United States and or other countries.
Storage, handling, and transport
NOTICE: Storage temperatures above 30 °C (86 °F)
greatly reduce the shelf life of DEF/AdBlue®.
DEF/AdBlue® has a typical shelf life of 6-12 months.
Refer to the SHELF LIFE table below. In order for
DEF/AdBlue® to remain in a usable condition, stor-
age requirements need to be met.
• Store between -11 °C (12 °F) and 30 °C (86 °F).
• Use only an approved DEF/AdBlue® container.
• Keep container tightly closed.
• Keep container in a cool, well-ventilated area.
• Keep away from heat and direct sunlight.
Thawing
• The machine is equipped with an internal tank
heater to thaw frozen DEF/AdBlue®. The machine
will still function until the DEF/AdBlue® begins to
flow. The SCR system will then function normally.
• Do not heat DEF/AdBlue® for long periods of time
at temperatures above 30 °C (86 °F). This causes the
solution to decompose, which very slowly decreases
the expected shelf life.
NOTICE: Do not use an anti-gelling or freeze point
improver in your DEF/AdBlue®. The 32.5 % solution
is specifically designed to provide the optimum NOx
reduction properties. Any further blending or adjust-
