MAINTENANCE 8.1 8.1.4 50 HOUR SERVICE CHECK 2 Hydraulic/Hydrostatic The following service check is to be performed by your dealer after the first 50 hours of operation. 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. 1 Engine 1.1 Oil Filter: Change the engine oil filter. Use only original replace- ment parts. Refer to section 7 for installation details. Change the oil filter every 150 hours thereafter. 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 SE/CD oil. Fill to the line marked next to the sight gauge. 1.2 Engine Oil: Change the engine oil. Use only 10W30 API classifica- tion SE/CD oil. Refer to section 7 for procedure. Change engine oil every 150 hours thereafter. 2.3 Hoses and Pipes: Make a visual inspection of all hydraulic lines and fit- tings for leaks, chaffing and tightness. Check that steel lines do not touch one another and clamps are tight. 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. 2.4 Cylinders: Inspect cylinders for leaks.
Extend cylinders and check for rod damage. Check pivot pins and bushings for wear. 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. 2.5 Hydraulic Functions: Check that the following operate properly: control valve float position, auxiliary hydraulic detent, hydraulic cylinders. 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. 2.6 Pumps & Motors: Inspect pumps and motors for leaks.
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. WARNING To avoid personal injury: never work under raised boom arms without the boom supports properly engaged. Shut off the engine and remove the key to prevent accidental engagement of the engine. Never repair or tighten hydraulic hoses or fittings with the engine running or the system under pressure. 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.
Check all hose clamps and check the air inlet outlet hoses for cracks or chaffing. 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 or replace. 8 1.9 Engine Speed: Check and if necessary adjust engine R.P.M. Maximum no load high idle: 3000 RPM. 8-8
