Section 3 - Maintenance Routine Maintenance Fluids, Lubricants and Capacities Coolant Mixtures Fuel T3-009_3 Check the strength of the coolant mixture at least once a year, preferably at the start of the cold period. 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. Replace the coolant mixture according to the intervals shown in the machine's Service Schedule. !M WARNING Antifreeze can be harmful. Obey the manufacturer's instructions when handling full strength or diluted antifreeze.
The following factors should be used to ensure that the service life of the fuel system is maintained. K Fuel Specifications ( T 3-25) 7-3-4-4_1 K Cleanliness ( T 3-26) 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. K Fuel Bulk Storage ( T 3-27) K Fuel Analysis ( T 3-27) Fuel Specifications The correct concentration of antifreeze protects the engine against frost damage in winter and provides year round protection against corrosion.
!M CAUTION Consult your fuel supplier or JCB distributor about the suitability of any fuel you are unsure of. GEN-9-2 The protection provided by JCB High Performance Antifreeze and Inhibitor is shown below. Recommended Fuel Specification 50% Concentration (Standard) The following fuels are recommended for use with Tier III machines. Protects against damage down to -40 °C (-39 °F) EN590 Diesel Fuel Types - Auto/Co/C1/C2/C3/C4. 60% Concentration (Extreme Conditions Only) Protects against damage down to -56 °C (-68 °F) ASTM D975-91 Class 2, US DF1, US DF2, US DFA. JIS K2204 (1996) Grades 2, 3, and Special Grade 3. Acceptable Fuel Specification Important:
Do not exceed a 60% concentration, as the freezing protection provided reduces beyond this point. The following fuels will require some additional care and service requirements. If you use any other brand of antifreeze: Ensure that the antifreeze complies with International Specification ASTM D6210. !M CAUTION 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. 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.
GEN-9-3 Ensure that the antifreeze is ethylene glycol based and does not use Organic Acid Technology (OAT). ASTM D975-91 Class 1-1DA. JP7, MIL T38219 XF63. NATO F63.
