6. Replace or sharpen the blades. To properly sharpen the cutting blades, remove equal amounts of metal from both ends of the blades along the cutting edges, parallel to the trailing edge, at a 25° to 30° angle. Always grind each cutting blade edge equally to maintain proper blade balance. See Figure 4-9. Figure 4-10 7. Test the blades for balance by balancing the blade on a round shaft screwdriver to check. If out of balance, when sharpening, remove metal from the heavy side until it balances evenly. During sharpening the blade, follow the original angle of grind. Grind each cutting edge equally to keep the blade balanced. WARNING: An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to mower and could break causing personal injury. 8. Slide the blades (b) onto the spindle shafts with the side marked "Grass Side" (or with part number) facing the ground when the mower is in the operating position. 9. Replace the hex flange nuts (a) and tighten to torque: 70 ft-lb (min.), 90 ft-lb (max.). To ensure safe operation of your mower, periodically check the blade bolt for correct torque. Belt Care Several components must be removed and special tools used in order to change the mower's belts. See your authorized service dealer to have belts replaced. Replacing Battery (If Equipped) WARNING: Batteries contain sulfuric acid which may cause burns. Do not short circuit or damage batteries in any way. Do not put batteries in fire as these may burst or release toxic materials. 1. Unhinge cover seal and remove battery cover. 2. Remove positive and negative leads from battery, and pull up on battery to remove. See Figure 4-10. Figure 4-11 3. Replace with new battery. Connect the positive lead (red) to the positive side of the battery pack, then connect the negative lead (black) to the negative side. See Figure 4-11. (+) Positive Terminal (-) Negative Terminal Figure 4-12 4. Reattach battery cover and cover seal. Charging Battery (If Equipped) WARNING: The battery contains corrosive fluid and toxic material; handle with care and keep away from children. Do not puncture, disassemble, damage or incinerate the battery. Explosive gases could be vented during charging or discharging. Use in a well ventilated area, away from sources of ignition. IMPORTANT: The special designed plug on the charger will only fit into plug on battery box. 1. Unhinge the cover seal and plug the battery charger into the port on the side of the battery housing. See Figure 4-12. 2 1 2. Insert the battery charger plug into a standard 120V household outlet. Charge battery for 8 to 10 hours before initial use. Do not charge longer than 12 hours. The battery should only need to be charged upon initial setup, at the end of the season, after any other extended periods of non-use, and as needed. NOTE: If you frequently stop and restart the mower during each cut throughout the season (for instance when bagging), more frequent charging may be necessary. 3. After charging, disconnect charger plug from outlet first, then disconnect charger lead from battery and reattach cover seal. IMPORTANT: Do not remove the battery pack from the electric starter housing for any reason other than replacement. IMPORTANT: Always plug charger lead into battery pack lead first, and then insert battery charger plug into 120V standard household outlet. Follow this order of action every time you charge the battery. Off-Season Storage Mower The following steps should be taken to prepare your lawn mower for storage. • Clean and lubricate mower thoroughly as described in Lubrication section on page 12. • Apply a coat of chassis grease to mower's cutting blades to prevent rusting. • Refer to Engine Operator's Manual for correct engine storage instructions. • Do not use a pressure washer to clean your unit. • Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer. When storing any type of power equipment in a poorly ventilated or metal storage shed, care should be taken to rust-proof the equipment. Using a light oil or silicone, coat the equipment, especially cables and all moving parts of your lawn mower before storage. Battery (If Equipped) • The battery must be stored with a full charge. Extended storage of a discharged battery will reduce life and capacity of the battery. For optimal battery life, charge the battery once per month while in storage. • Remove electric starter push key (if equipped) and keep in a safe place out of the reach of children.
