Battery Figure 6 OF4110 HYDRAULIC FLUID Check Hydraulic Fluid Level Check the system with the unit cold and parked on a flat, level surface. Then run the unit for about one minute and recheck the levels. To Add Hydraulic Fluid: 1. Remove the cap from the expansion tank. 2. Fill the expansion tank with 20W-50 engine oil with an SL API classification until oil level reaches the cold fill line on the tank. 3. Install the expansion tank cap and then purge the system. See Purging the Hydraulic System on page 20. The hydraulic fluid should be at the cold fill line of the expansion tank. WARNING: HYDRAULIC FLUID can result in severe burns. Fluid in hydraulic system can penetrate skin and result in serious injury or death. Be sure to stop the engine before doing any work on hydraulic parts. Keep body and hands away from pin holes or nozzles which expel hydraulic fluid when under pressure. Use paper or cardboard, not hands, to search for leaks. Ensure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to system. FOREIGN FLUID INJECTED INTO BODY can result in gangrene. Fluid must be surgically removed within a few hours by a doctor familiar with this form of injury. Figure 7 Change Hydraulic Fluid and Filter NOTE: Change hydraulic fluid and filter after the first 75 hours of operation and then every 400 hours. Use 20W-50 engine oil with an SL API classification. 1. Place container under oil filter to catch oil. 2. Remove the filter guard and oil filter from the transaxle. 3. Remove the oil drain plug or fitting from the inlet port and allow the transaxle to drain completely. 4. Clean the filter mounting surface and then lubricate rubber gasket on new oil filter with clean hydraulic oil. 5. Spin new oil filter onto filter housing until it makes contact. Tighten oil filter another 3/4 turn. 6. Install the filter guards removed in step 2. Tighten the mounting screws to 65 lbf-in (7.3 N•m). GB - 19
