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.
Standard hydraulic oil
CASE AKCELA HYDRAULIC EXCAVATOR FLUID
meets the CNH material specification MAT 3509 and is
specifically designed for high pressure applications and
for CASE CONSTRUCTION hydraulic systems.
Your
CASE CONSTRUCTION dealer can provide hydraulic
fluid to fulfill different climate/temperature conditions.
Refer to the charts at the beginning of this section.
Alternative hydraulic oil – Biodegradable oil
The hydraulic system of this machine can be filled at the
factory with environmentally friendly, biodegradable hy-
draulic fluid (nonstandard). Stickers with corresponding
instructions are then attached to the machine.
For the initial filling, we use only: PANOLIN HLP SYNTH
VG 46
This synthetic hydraulic fluid has been tested by CASE
CONSTRUCTION and approved for use in our ma-
chines. A changeover from mineral hydraulic fluid to this
biodegradable hydraulic fluid can, however, be made at
a later date.
Environmentally friendly, biodegradable, hydraulic fluid
must be properly disposed of in the same manner as
other used oil.
