6. 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. 7. Replace the oil filter and refill the engine with new oil as instructed in the engine operator's manual. Refer to the Engine Operator's Manual for information regarding the volume and weight of engine oil. 8. Route the hose back along the frame as it was before removal. Lubrication Periodically lubricate all pivot points with a quality lubricating oil. Tires Check the tire air pressure after every 50 hours of operation or weekly. Keep the tires inflated to the recommended pressures. Improper inflation will shorten the tire service life and produce an uneven cut. The recommended operating rear tire pressure is 14 psi. Observe the following guidelines: • Do not inflate a tire above the maximum pressure shown on the sidewall of the tire. • Do not reinflate a tire that has been run flat or seriously under inflated. Have it inspected and serviced by a qualified tire mechanic. Battery Information WARNING Should battery acid accidentally splatter into the eyes or onto the skin, rinse the affected area immediately with clean cold water. If there is any further discomfort, seek prompt medical attention. If acid spills on clothing, first dilute it with clean water, then neutralize with a solution of ammonia/water or baking soda/water. NEVER connect (or disconnect) battery charger clips to the battery while the charger is turned on, as it can cause sparks. Keep all sources of ignition (cigarettes, matches, lighters) away from the battery. The gas generated during charging can be combustible. As a further precaution, only charge the battery in a well ventilated area. Always shield eyes and protect skin and clothing when working near batteries. Batteries contain sulfuric acid and may emit explosive gases. Use extreme caution when handling batteries. Keep batteries out of the reach of children. Battery Maintenance • The battery is filled with battery acid and then sealed at the factory. However, even a "maintenance free" battery requires some maintenance to ensure its proper life cycle. • Spray the terminals and exposed wire with a battery terminal sealer, or coat the terminals with a thin coat of grease or petroleum jelly, to protect against corrosion. • Always keep the battery cables and terminals clean and free of corrosion. • Avoid tipping. Even a sealed battery will leak electrolyte when tipped. WARNING Batteries contain sulfuric acid and may emit explosive gases. Use extreme caution when handling batteries. Keep batteries out of the reach of children. 14 Section 4- Product Care Battery Storage 1. When storing the mower for extended periods, disconnect the negative battery cable. It is not necessary to remove the battery. 2. All batteries discharge during storage. Keep the exterior of the battery clean, especially the top. A dirty battery will discharge more rapidly. 3. The battery must be stored with a full charge. A discharged battery can freeze sooner than a charged battery. A fully charged battery will store longer in cold temperatures than hot. 4. Recharge the battery before returning to service. Although the mower may start, the engine charging system may not fully recharge the battery. Removing the Battery 1. Remove the flange lock nut (a) and carriage screw (b) holding the battery hold-down bracket (c) in place. See Figure 4-5. (c) (a) (b) Figure 4-5 2. Remove the battery hold-down bracket. 3. Remove the hex cap screw and sems nut securing the black negative battery lead (b) to the negative battery post (marked NEG). Move the cable away from the negative battery post. 4. Remove the hex cap screw and sems nut securing the red positive battery lead (c) to the positive battery post (marked POS). 5. Carefully slide the battery out of the mower. 6. Install the battery by repeating the above steps in the reverse order. Using the Transmission Bypass Rods If for any reason the mower will not drive or you wish to move the mower, the two hydrostatic transmissions are equipped with a bypass rod that will allow you to manually move the mower short distances. WARNING Do not tow the mower, even with the bypass rod engaged. Serious transmission damage will result from doing so. 1. Engage the transmission bypass by pulling out on the bypass rod (a) and then placing it down in the slot before releasing. See Figure 4-6. Pull Out (a) (a) Down Figure 4-6 2. To release the transmission bypass, pull out and let the bypass rod slide back into the frame. Hydrostatic Transmission The mower is equipped with dual integrated hydrostatic pumps/transaxles that are sealed. 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: Note: See the Maintenance Schedule table on page 12 for transmission oil changing intervals. WARNING Check the oil level ONLY before starting the mower when the transmission oil is fully cooled. 1. Clean the reservoir cap and the area around the cap to prevent debris from contaminating the transmission oil. See Figure 4-7. Figure 4-7 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 4-7. DO NOT FILL THE RESERVOIR.
