INTRODUCTION
Basic instructions
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. Anti-rust additives
and ethylene-glycol can mix and work against each other, reducing anti-corrosion protection, forming deposits in the
cooling system, and causing 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 system 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 conditions ( ASTM D975).
Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard (North America). In Europa,
fuel must comply with specification standard EN 590 or ITS EQUIVALENT.
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.
Engine oil
NEW HOLLAND AMBRA UNITEK CJ-4 ENGINE OIL SAE
15W-40 is recommended for your engine. This oil insures
correct lubrication of your engine in all working conditions.
See General specification () to choose the correct oil for
climate/temperatures.
If NEW HOLLAND AMBRA UNITEK CJ-4 ENGINE OIL SAE
15W-40 cannot be obtained, use only oil of the API CI4
category.
NOTE: Do not put any performance additive or other additive in the sump. Oil change intervals shown in this
manual are based on tests carried out utilizing NEW HOLLAND CONSTRUCTION lubricants.
LELI12WL30004AA
1
Fuel storage
Prolonged storage of fue l 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.

INTRODUCTION
Hydraulic fluid
NEW HOLLAND AMBRA HYDROSYSTEM 46 HV is specifically designed for high pressure applications and for NEW
HOLLAND CONSTRUCTION hydraulic systems. Your NEW HOLLAND CONSTRUCTION Dealer can provide hydraulic fluid to fulfill different climate/temperature conditions. Refer to the General specification ().
Transmission component oil
Extreme pressure oil should be used for enclosed transmission components. Choose an oil that is manufactured for
your climate/temperature conditions such as NEW HOLLAND AMBRA MULTI G 134™ HYDRAULIC TRANSMISSION OIL.
See General specification ().
Grease
The type of grease to use depends on ambient temperature such as: NEW HOLLAND AMBRA GR 75 MD.
Environment
Before you service this machine and dispose of oil, fluids, 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.

During these tests the engine runs at full throttle
and works against the torque converter, the hydraulic
system, or both the torque converter and the hydraulic system. The results of these tests will show if
the cause of poor performance is one or more of the
following:
1.
Engine
2.
Torque converter or transmission
3.
Hydraulic system

engine at this speed for 30 s.
9.
Decrease the engine speed to low idle and move the
transmission control lever to the neutral position for
15 s.
10.
Repeat steps 7, 8, and 9 until the temperature of the
torque converter oil is 82 - 104 °C (180 - 219 °F).

Understanding the results of test No. 1
1.
If the engine speed was as specified, the engine,

are probably good.
2.
If the engine speed was not as specified, do Test No.

Engine - Engine and crankcase
Understanding the results of test No. 2
1.
If the engine speed was as specified, the engine,
torque converter and transmission are probably
good.
2.
If the engine speed was more than specified, the
problem can be in the torque converter or the transmission. See Mechanical transmission - Dynamic
description (21.114) for troubleshooting information.
3.
If the engine speed was less than specified, do Test
No. 3.
Test No. 3 - Hydraulic stall
1.
Sit in the seat.
2.
Start the engine and run the engine at low idle.
3.
Increase the engine speed to full throttle.
4.
Hold the bucket control lever in the ROLLBACK position and raise the lift arms. The stall speed must be
read while the lift arms are in motion.
5.
Check the engine speed.
6.
Release the bucket control lever.
7.
Decrease the engine speed to low idle.
8.
Lower the bucket to the ground.
9.
Stop the engine.
Understanding the results of test No. 3
1.
If the engine speed was as specified, the engine and
hydraulic system are good.
2.
If the engine speed was more or less than specified the main relief setting may be too low or too
high. See Hydraulic systems - Service instruction
(35.000) for troubleshooting information.
3.
If the engine speed was less than specified in all
tests, the engine is probably the cause.
