Coolant Mixtures
T3-009_3
Check the strength of the coolant mixture at least once a
year, preferably at the start of the cold period.
Replace the coolant mixture according to the intervals
shown in the machine's Service Schedule.
!MWARNING
Antifreeze can be harmful. Obey the manufacturer's
instructions when handling full strength or diluted
antifreeze.
7-3-4-4_1
You must dilute full strength antifreeze with clean water
before use. Use clean water of no more than a moderate
hardness (pH value 8.5). If this cannot be obtained, use
de-ionized water. For further information advice on water
hardness, contact your local water authority.
The correct concentration of antifreeze protects the engine
against frost damage in winter and provides year round
protection against corrosion.
The protection provided by JCB High Performance
Antifreeze and Inhibitor is shown below.
Important: Do not exceed a 60% concentration, as the
freezing protection provided reduces beyond this point.
If you use any other brand of antifreeze:
– Ensure that the antifreeze complies with International
Specification ASTM D6210.
– Always read and understand the manufacturer's
instructions.
– Ensure that a corrosion inhibitor is included. Serious
damage to the cooling system can occur if corrosion
inhibitors are not used.
– Ensure that the antifreeze is ethylene glycol based
and does not use Organic Acid Technology (OAT).
Fuel
Introduction
The quality and grade of fuel can seriously affect the
service life of the fuel system. It is vitally important that the
correct grade of fuel is used, a high standard of fuel
storage is maintained and the use of old fuel is avoided.
The following factors should be used to ensure that the
service life of the fuel system is maintained.

Fuel Specifications
!MCAUTION
Consult your fuel supplier or JCB distributor about the
suitability of any fuel you are unsure of.
GEN-9-2
Recommended Fuel Specification
The following fuels are recommended for use with Tier III
machines.
– EN590 Diesel Fuel Types - Auto/Co/C1/C2/C3/C4.
– ASTM D975-91 Class 2, US DF1, US DF2, US DFA.
– JIS K2204 (1996) Grades 2, 3, and Special Grade 3.
Acceptable Fuel Specification
The following fuels will require some additional care and
service requirements.
!MCAUTION
The fuel specification below is acceptable, however
this fuel may reduce the life of the fuel injection
equipment. The use of this fuel may also affect the
engine performance.
GEN-9-3
– ASTM D975-91 Class 1-1DA.
– JP7, MIL T38219 XF63.
–NATO F63.
– French EN590 (RME5) with 5% maximum.
– RME content blended with mineral derived diesel (5%
maximum)
Low Sulphur Fuels
Low sulphur fuels must have the appropriate fuel lubricity
additives added to prevent premature wear of the pump
50% Concentration (Standard)
Protects against damage down to -40 °C (-39 °F)
60% Concentration (Extreme Conditions Only)
Protects against damage down to -56 °C (-68 °F)
