Maintenance WARNING! Before performing any maintenance or repairs, disengage the PTO, move the drive control levers fully outward in the neutral position, engage the parking brake, stop the engine and remove the key to prevent unintended starting. Engine Refer to the Kohler Owner's Manual for all engine maintenance intervals, procedures, specifications and instructions. Changing the Engine Oil WARNING ! If the engine has been recently run, the engine, muffler and surrounding metal surfaces will be hot and can cause burns to the skin. Exercise caution to avoid burns. To complete an oil change, proceed as follows: 1. Run the engine for a short time to warm the engine oil. The oil will flow more freely and carry away more impurities. Use care to avoid burns from hot oil. 2. Locate the oil drain hose on the engine. 3. Route the free end of the oil drain hose toward an appropriate oil collection container with at least a 2.5 quart capacity, to collect the used oil. Remove the oil fill cap/ dipstick from the oil fill tube. 4. While holding the free end of the oil drain hose over the oil collection container, unscrew the square-head hose plug from the end of the hose. See Figure 1-1. Drain the engine oil into the collection container. Hydrostatic Transmission Your zero turn tractor is equipped with dual integrated hydrostatic pumps/transaxles that are sealed and are maintenance-free. However, this model is equipped with a transmission oil expansion reservoir. Under normal operating conditions, the oil level in the expansion reservoir does not need to be checked and no additional oil is needed. If checking the reservoir oil level, proceed as follows: WARNING! Check the oil level ONLY before starting the tractor when the transmission oil is fully cooled. 1. Pivot the operator's seat forward and clean the reservoir cap and the area around the cap to prevent debris from contaminating the transmission oil. See Figure 1-2. Full Cold Line Square-Head Hose Plug Figure 1-1 5. After draining the oil, wipe any residual oil from the oil drain hose. Thread the square head plug into the drain hose fitting and fully tighten the plug. 6. Refill the engine with new oil. Refer to the Kohler Owner's Manual for information regarding the volume and weight of engine oil. Figure 1-2 2. Turn the reservoir cap counterclockwise to re-move, then check the oil level in the reservoir. Oil should be visible at the bottom of the cup, but the oil level must NOT be above the "FULL COLD" line. See Figure 1-2. DO NOT FILL THE RESERVOIR. 3. If necessary to add oil because of some type of leakage, use a quality 20W50 motor oil and add only enough oil to bring the level to the "FULL COLD" line. Reinstall the cap and fully tighten. NOTE: Prior to the initial operation of the tractor, the oil level in the reservoir may be slightly higher than the maximum due to air in the oil lines. Operation of the tractor will eventually purge the air from the lines and the oil level will settle to the maximum. Lubrication • Using a pressure lubricating gun, lubricate all grease fittings and points as noted in the Lubrication Chart. • Lubricate all other pivot points with a quality lubricating oil as noted in the Oil Chart. 24 Section 6- Maintenance & Adjustments
