4. 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 7-7. Jump Starting WARNING! Never jump start a damaged or frozen battery. Be certain the vehicles do not touch and ignitions are off. Do not allow cable clamps to touch. 1. Connect positive (+) cable to positive post (+) of your tractor's discharged battery. 2. Connect the other end of the cable to the positive (+) post of the jumper battery. 3. Connect the second cable negative (-) to the other post of the jumper battery. 4. Make the final connection on the engine block of the tractor, away from the battery. Attach to an unpainted part to assure a good connection. CAUTION: If the jumper battery is installed on a vehicle (i.e. car, truck), do NOT start the vehicle's engine when jump starting your tractor. Figure 7-7 CAUTION: If the cutting edge of the blade has previously been sharpened, or if any metal separation is present, replace the blades with new ones. WARNING! A poorly balanced blade will cause excessive vibration, may cause damage to the tractor and/or result in personal injury. 5. Test the blade's balance using a blade balancer. Grind metal from the heavy side until it balances evenly. NOTE: When replacing the blade, be sure to install the blade with the side of the blade marked ''Bottom'' (or with a part number stamped in it) facing the ground when the mower is in the operating position. CAUTION: Use a torque wrench to tighten the blade spindle hex flange nut to between 70 ft-lbs and 90 ft-lbs. Battery CALIFORNIA PROPOSITION 65 WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. CAUTION: If removing the battery, disconnect the NEGATIVE (Black) wire from it's terminal first, followed by the POSITIVE (Red) wire. When reinstalling the battery, always connect the POSITIVE (Red) wire its terminal first, followed by the NEGATIVE (Black) wire. 5. Start the tractor (as instructed in the Operation section of this manual). 6. Set the tractor's parking brake before removing the jumper cables, in reverse order of connection. Charging WARNING! Batteries give off an explosive gas while charging. Charge the battery in a well ventilated area and keep away from an open flame or pilot light as on a water heater, space heater, furnace, clothes dryer or other gas appliances. CAUTION: When charging your tractor's battery, use only a charger designed for 12V lead-acid batteries. Read your battery charger's Owner's Manual prior to charging your tractor's battery. Always follow its instructions and heed its warnings. If your tractor has not been put into use for an extended period of time, charge the battery as follows: 1. Set your battery charger to deliver a max of 10 amperes. 2. If your battery charger is automatic, charge the battery until the charger indicates that charging is complete. If the charger is not automatic, charge for no fewer than eight hours. Fuse WARNING! Before servicing, repairing, or inspecting, always disengage PTO, set parking brake, stop engine and remove key to prevent unintended starting. A 20 Amp fuse is installed in your tractor's wiring harness to protect the tractor's electrical system from damage caused by excessive amperage. If the electrical system does not function, or your tractor's engine will not crank, first check to be certain that the fuse has not blown. It is located under the hood, mounted behind the top of the dash panel on the support bar. 26 Section 7- Service
