GENERAL INFORMATION
Cleanning
Clean all metal parts except bearings, in a suitable
cleaning solvent or by steam cleaning. Do not use
caustic soda for steam cleaning. After cleaning, dry
and put oil on all parts. Clean oil passages with
compressed air. Clean bearings in a suitable cleaning
solvent, dry the bearings completely and put oil on
the bearings.
Inspection
Check all parts when the parts are disassembled.
Replace all parts that have wear or damage. Small
scoring or grooves can be removed with a hone or
crocus cloth. Complete a visual inspection for
indications of wear, pitting and the replacement of
parts necessary to prevent early failures.
Bearings
Check bearings for easy action. If bearings have a
loose fit or rough action replace the bearing. Wash
bearings with a suitable cleaning solvent and permit
to air dry. DO NOT DRY BEARINGS WITH
COMPRESSED AIR.
Needle bearings
Before you press needle bearings in a bore always
remove any metal protrusions in the bore or edge of
the bore. Before you press bearings into position put
petroleum jelly on the inside and outside diameter of
the bearings.
Gears
Check all gears for wear and damage. Replace gears
that have wear or damage.
Oil seals, O-rings and gaskets
Always install new oil seals, O-rings and gaskets. Put
petroleum jelly on seals and O-rings.
Shafts
Check all shafts that have wear or damage. Check
the bearing and oil seal surfaces of the shafts for
damage.
Service parts
Always install genuine Case service parts. When
ordering refer to the Parts Catalog for the correct part
number of the genuine Case replacement items.
Failures due to the use of other than genuine Case
replacement parts are not covered by warranty.
Lubrication
Only use the oils and lubricants specified in the
Operator’s or Service Manuals. Failures due to the
use of non-specified oils and lubricants are not
covered by warranty.

.
WARNING: Read the operator’s manual to
familiarize yourself with the correct control
functions.
!
WARNING: Operate the machine and
equipment controls from the seat position
only. Any other method could result in
serious injury.
!
WARNING: This is a one man machine, no
riders allowed.
!
WARNING: Before starting engine, study
Operator’s Manual safety messages. Read
all safety signs on machine. Clear the area of
other persons. Learn and practice safe use
of controls before operating.
It is your responsibility to understand and
follow manufacturers instructions on
machine operation, service and to observe
pertinent laws and regulations. Operator’s
and Service Manuals may be obtained from
your Case dealer.
!
WARNING: If you wear clothing that is too

FLUIDS AND LUBRICANTS
Lubricants must have the correct properties for each application.
Hydraulic fluid
CASE/AKCELA hydraulic fluid is specially designed for high pressure applications and for the CASE hydraulic system.
The type of fluid to be used depends on the ambient temperature.
Temperate climates: -20°C to +40°C (-4° to 104° F)
CASE/AKCELA: HYDRAULIC EXCAVATOR FLUID (MS 1230. ISO VG 46. DIN 51524 PART 2 HV)

Biodegradable fluid: -30°C to +40°C (-22° to 104° F)
This yellow-colored fluid is miscible with standard fluid. If used to change standard fluid, it is advised to drain the circuit
completely before refilling with this fluid.
CASE/AKCELA: HYDRAULIC EXCAVATOR FLUID BIO (MS 1230. ISO VG 46. DIN 51524 PART 2 HV)
Transmission component oil

Engine Oil
THE CASE/AKCELA No. 1 engine oil is recommended
for your engine. This oil ensures proper lubrication of
your engine for all operating conditions.
If the CASE/AKCELA Multigrade "No. 1 ENGINE OIL"
cannot be obtained, use the oil corresponding to one of
the following categories: ACEA E7. API CI-4.
CP02N001

Fuel
Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard.
Use grade No. 2-D 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 cold weather (below -7°C (19.4°F)), it is provisionally approved to use a mixture of fuels No. 1-D and No. 2-D. Consult
your fuel supplier or your CASE Dealer.
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.
Required conditions for diesel fuel
The diesel fuel used must:
- be free from dust particles, even minute ones.
- have the proper viscosity.
- have a high cetane number.
- present great fluidity at low temperatures.
- have low sulphur content.
- have very little residual carbon.
Diesel fuel recommendation
- JIS (Japanese Industrial Standard) : No. 2
- DIN (Deutsche Industrie Normen) : DIN 51601
- SAE (Society of Automotive Engineers) Based on SAE-J-313C: No. 2-D
- BS (British Standard) Based on BS/2869-1970: Class A-1
IMPORTANT : Using any other fuel will reduce the operating performance of the engine.
Using fuels other than those recommended can damage the fuel injection pump, the injector and other parts of the fuel
supply system and the engine. CASE disowns any responsibility concerning this kind of damage, which is not
covered by the guarantee. To avoid any damage to the engine fuel supply system, you are recommended to take the
following safety messages into account:
Some fuel suppliers mix used engine oil with diesel fuel. Certain manufacturers of large engines allow them to do this.
However, for your engine, do not use diesel fuel contaminated by engine oil. In addition to damaging the engine, this fuel
can actually adversely affect the correct purification of exhaust gases. Before using any diesel fuel, ask the supplier if
this fuel has been mixed with engine oil.
IMPORTANT : For a proper use of fuel additives consult your supplier or your CASE Dealer. Do not inject fuel oil or
gasoline, both fuels can damage the engine.
IMPORTANT : In cold weather, fill the fuel tank at the end of the day's work, in order to prevent the formation of conden-
sation.
Fuel storage
Long storage 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 temperature of the fuel should be kept as low as possible. Drain off
water and impurities regularly.

Lep SM290B1002-1NA Issued 01-2010
1002-8
Anti-freeze/Anti-corrosion
Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing.
CASE/AKCELA: PREMIUM ANTI-FREEZE (MS 1710)
For areas where the temperature goes down to -38°C (-36.4°F), mix 50/50 with water.
IMPORTANT : Do not mix products of a different origin or brand. The same product must be used when topping up the
system.
Environment
Before carrying out any maintenance operation on this machine and before disposing of used fluids or lubricants,
always think of the environment. Never throw oil or fluid on the ground and never place it in leaking receptacles.
Contact your local ecological recycling centre or your CASE Dealer to obtain information on the correct method of dis-
posing of these lubricants.
Plastic and resin parts
When cleaning plastic parts, the console, the instrument panel, the indicators etc... avoid using petrol, kerosene, paint
solvents etc... Use only water, soap and a soft cloth.
The use of petrol, kerosene, paint solvents etc... causes discoloration, cracks or deformation of these parts.
