ITEM SPECIFICATIONS Engine oil SAE 10W-30 API classification CD Hydraulic system oil SAE 10W-30 API classification CD Biodegradable hydraulic system oil (Only for machines in which the synthetic biode- gradable oil type HEES not of plant origin is used) PAKELO GEOLUBE HYDRAULIC EP-46 Hydraulic transmission oil GM DEXRON ® II D Front and rear axle oil UTTO FLUID Braking system oil GM DEXRON ® II D Fuel With ambient temperature over -10° C: ASTM D975 no. 2 diesel oil With ambient temperature under -10°C: ASTM D975 no.
1 diesel oil Radiator Permanent, ethylene glycol-based antifreeze, with corrosion inhibitor for protection up to -36°C GM DEXRON ® II D (DEXRON ® is a registered trademark of General Motors Corporation) 4.2.1 NOTES REGARDING THE ENGINE 4.2.1.1 ENGINE OIL The engine oil must be selected very carefully, since it lubricates the engine, which is the machine’s heart; the main maintenance operations required for the engine oil are the following: 1 - Daily check of the oil level. 2 - Check of the degree of pollution of the oil. 3 - Periodical change.
4.2.1.2 COOLANT The coolant serves to keep the engine at the correct temperature and therefore to ensure optimal operatng conditions; check the coolant level in the expansion tank daily and top up if necessary. The coolant containing antifreeze is flammable; do not use naked flames near the coolant and do not smoke while topping up. 144
