( 1 ) When you are operating the machine in temperatures below -20°C (-4°F), refer to Special Publication, SEBU5898, "Cold Weather Recommendations for All Caterpillar Machines". This is available from your Caterpillar dealer.

( 2 ) Supplemental heat is recommended for cold soaked starts below the minimum ambient temperature. Supplemental heat may be required for cold soaked starts that are above the minimum temperature that is stated, depending on the parasitic load and other factors. Cold soaked starts occur when the engine has not been operated for a period of time. This allows the oil to become more viscous due to cooler ambient temperatures.

( 3 ) API CF oils are not recommended for Caterpillar 3500 Series and smaller Direct Injection (DI) diesel engines. API CF-4 oils are not recommended for diesel engines for Caterpillar machines.

( 4 ) Cat Arctic DEO SYN is an SAE 0W-30 viscosity grade oil.( 5 ) API CI-4, API CI-4 PLUS, and API CH-4 oils are acceptable if the requirements of Caterpillar's ECF-1 (Engine Crankcase

Fluid specification - 1) are met. API CI-4, API CI-4 PLUS, and API CH-4 oils that have not met the requirements of Cat ECF-1 specification may cause reduced engine life.

( 6 ) API CG-4 oils are acceptable for use in all Cat machine diesel engines. When API CG-4 oils are used, the oil change interval should not exceed 250 hours. API CG-4 oils that also meet API CI-4, API CI-4 PLUS, or API CH-4 must also meet the requirements of the Caterpillar ECF-1 specification.



( 7 ) SAE 10W-30 is the preferred viscosity grade for the 3116, 3126, C7, C-9 and the C9 diesel engines when the ambient temperature is between -18° C (0° F) and 40° C (104° F).

( 8 ) First Choice: Cat Arctic TDTO SYN - SAE 0W-20. Second Choice: Oils of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Third Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.

( 9 ) First Choice: Oils of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Second Choice: Oils with a TO-4 type additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.

( 10 ) Except for the hydraulic drive winch gear case. Use SAE 30 viscosity grade for 0°C (32°F) to 43°C (110°F) or Cat TDTO-TMS for -20°C (-4°F) to 50°C (122°F).

( 11 ) Do not use SAE 50 viscosity grade oil in ICM controlled transmissions. Do not use SAE 50 viscosity grade oil for the hydraulic drive winch case.

( 12 ) Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the TO-4M multigrade specification requirements).

( 13 ) Commercial biodegradable hydraulic oil (HEES) must meet the Caterpillar BF-1 specification. The listed ambient temperature range is for the current Cat BIO HYDO (HEES), not for commercial BF-1 oil.

( 14 ) Refer to the machine Operation and Maintenance Manual or contact your local Caterpillar dealer before using Cat BIO HYDO (HEES) or commercial BF-1 oil in Caterpillar Hydraulic Excavators.

( 1 ) In order to use a non-Caterpillar lubricant, the supplier must certify that the lubricant is compatible with Caterpillar's grease. Otherwise, each pin joint should be fully flushed with the new lubricant in order to entirely remove the Caterpillar lubricant. Failure to meet this requirement may lead to failure of a pin joint due to premature breakdown of the lubricant.
