7 - MAINTENANCE
Fuel
Use diesel fuel suitable for the ambient temperature con-
ditions (ASTM-D-975).
Use fuel which is to ASTM (American Society for Testing
and Materials) D975 standard.
Use grade No. 2 fuel. The use of other types of fuel can
result in a loss of power of the engine and may cause high
fuel consumption.
In very low ambient temperatures, use a mixture of fuels
No. 1 and No. 2 as necessary. Consult your fuel supplier
for appropriate fuel supply.
If the temperature falls below the fuel cloud point (point
at which wax begins to form) the wax crystals will cause
power loss or will prevent the engine from starting.
In cold weather, fill the fuel tank at the end of the day's
work in order to prevent the formation of condensation.
Coolant solution
Put only ethylene-glycol coolant solution in the cooling
system. Use good quality ethylene-glycol that has a high
boiling point with no additives to prevent leakage. Do not
use non-approved anti-rust additives.
NOTICE: Anti-rust additives and ethylene-glycol can mix
and work against each other, reducing anti-corrosion pro-
tection, forming deposits in the cooling system, and caus-
ing damage to the cooling system and radiator. Contact
your dealer who can supply you with the suitable coolant
solution.
Anti-freeze/Anti-corrosion
Use anti-freeze in all seasons to protect the cooling sys-
tem from corrosion and risk of freezing. For areas where
the ambient temperature is over
-36 °C ( -32.8 °F ) use a
blend of 50 % ethylene-glycol based anti-freeze.
For areas where the temperature is below -36 °C
( -32.8 °F )- it is advisable to use a blend of 40 % water
and 60 % anti-freeze.
Fuel
Use diesel fuel suitable for the ambient temperature con-
ditions (ASTM-D-975).
Use fuel which is to ASTM (American Society for Testing
and Materials) D975 standard.
Use grade No. 2 fuel. The use of other types of fuel can
result in a loss of power of the engine and may cause high
fuel consumption.
In very low ambient temperatures, use a mixture of fuels
No. 1 and No. 2 as necessary. Consult your fuel supplier
for appropriate fuel supply.
If the temperature falls below the fuel cloud point (point
at which wax begins to form) the wax crystals will cause
power loss or will prevent the engine from starting.
In cold weather, fill the fuel tank at the end of the day's
work in order to prevent the formation of condensation.
Fuel storage
Prolonged storage of fuel can lead to the accumulation of
impurities and condensation in the fuel. Engine trouble
can often be traced to the presence of water in the fuel.
The storage tank must be placed outside and the temper-
ature of the fuel should be kept as low as possible. Drain
off water and impurities regularly.
Hydraulic fluid
Akcela Hydraulic excavator fluid is specifically de-
signed for high pressure applications and for Case hy-
draulic systems. Your Case Dealer can provide hydraulic
fluid to fulfill different climate/temperature conditions.
Refer to the charts at the beginning of this section.
Transmission component oil
Extreme pressure oil should be used for enclosed trans-
mission components. Choose an oil that is manufactured
for your climate/temperature conditions such as
Akcela
NEXPLORE™ fluid See charts at the beginning of this
section.
Grease
The type of grease to use depends on ambient tempera-
ture such as:
Akcela Moly grease .
Environment
Before you service this machine and dispose of oil, flu-
ids, and lubricants, obey environmental regulations. Do
not drain oil or fluids on to the ground or into containers
that leak. Check with your local environmental, recycling
center or your dealer for correct disposal information.
Engine oil
Akcela Unitek CJ-4 engine oil is recommended for your
engine. This oil insures correct lubrication of your engine
in all working conditions. See charts at the beginning of
this section to choose the correct oil for climate/temper-
atures. If
Akcela Unitek CJ-4 engine oil cannot be ob-
tained, use only oil of the API SERVICE CI-4 category.
NOTE: Do not put any Performance Additive or other ad-
ditive in the sump. Oil change intervals shown in this
manual are based on tests carried out utilizing Case lu-
bricants.
