Use only original replace- ment parts. Refer to section 7 for installation details. Change the oil filter every 150 hours thereafter. 1.2 Engine Oil: Change the engine oil. Use only 10W30 API classifica- tion CF oil. Refer to section 7 for procedure. Change engine oil every 150 hours thereafter. 1.3 Coolant Level: Check that the coolant is to the proper level. The cool- ing system is filled with a 50% mixture of ethylene gly- col and water. 1.4 Radiator for Leakage and Dirt:
If necessary flush the radiator with compressed air and / or water. (40 psi [27 kPa] max) Dirt buildup on the radiator cooling fins can cause both engine and hydraulic system overheating. Check rubber gasket on radiator to door baffle. 1.5 Fan Belt Tension and Condition: Check fan belt for cuts or wear, if necessary replace. Check tension and adjust as shown in section 7. 1.6 Fuel System for Leaks: Make a visual inspection of fuel system for leaks and potential hazards such as fuel line(s) touching exhaust manifold, flywheel, etc. Replace fuel filter every 400 hours. 1.7 Air Intake and Cleaner System: Follow the manufacturers inspection procedures.
Check that the filter indicator is not indicating that fil- ter service is required. 1.8 Exhaust System: Visually inspect the exhaust system and ensure all clamps are secure and the manifold bolts/nuts are tight. Check muffler for carbon and soot build up and plug- ging. If necessary clean. Inspect for exhaust leaks. 1.9 Engine Speed: Check and if necessary adjust engine rpm Maximum no load high idle: 2950 rpm. 1.10 Universal Joint: Check the condition of the engine universal joints and splines. Lubricate the u-joints with 2 ~ 3 pumps of multi purpose grease. 2 Hydraulic/Hydrostatic 2.1 Hydraulic Oil Filter: Change the hydraulic oil filter.
Change the hydraulic filter every 150 hours after the initial change. Lubricate the filter cartridge seal with system fluid. 2.2 Hydraulic Oil Level: If oil is visible in the oil level sight glass the level is satisfactory. If additional oil is required use only 10W30 API classification SJ oil. Fill to the line marked next to the sight gauge. 2.3 Hoses and Pipes: Make a visual inspection of all hydraulic lines and fit- tings for leaks. Check that steel lines do not touch one another and clamps are tight. 2.4 Cylinders: Inspect cylinders for leaks. Extend cylinders and check for rod damage. 2.5 Hydraulic Functions: Check that the following operate properly:
control valve float position, auxiliary hydraulic detent, hydraulic cylinders. 2.6 Pumps & Motors, Leakage: Inspect pumps and motors for leaks. 2.7 Oil Cooler: Inspect the oil cooler for leaks, fin damage or clogged with dirt. If necessary flush fins with compressed air and / or water. WARNING To avoid personal injury:never repair or tighten hydraulic hoses or fittings with the engine running or the system under pressure.
