Cub Cadet PRO Z 772 L Operation Manual - Page 17

OPERATION 2. Operator must be sitting in the mower seat with both drive control levers in the neutral/start position. 3. Engage the parking brake. 4. Make certain the PTO is in the disengaged (down) position. 5. Lift the choke knob (if equipped) into the ON position. NOTE: If the engine is warmed up, it may not be necessary to choke the engine. NOTE: Some mowers are equipped with EFI (Electronic Fuel Injection) engines and are not equipped with a choke. 6. Move the throttle control to midway between the SLOW positions. and FAST 7. Turn the ignition key clockwise to the START position and release it as soon as the engine starts; however, do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start within this time, turn the key to OFF and wait at least 30 seconds to allow the engine's starter motor to cool. Try again after waiting. If after a few attempts the engine fails to start, do not keep trying to start it with the choke closed as this will cause flooding and make starting more difficult. 8. Once the engine starts, push the choke (if equipped) halfway down and as the engine warms, push the choke (if equipped) all the way down. Electronic Throttle (E-Governor)/EFI (Electronic Fuel Injection) Engines 1. Open the fuel valve(s). NOTE: For dual valve models (if equipped), if both tanks are on, and one is empty, the engine will not start. Be certain to make sure both tanks have fuel or that the empty tank's fuel valve is closed. For single valve models (if equipped), if fuel flow is shut off, the engine will not start. NOTE: To prime a dry fuel system, turn the ignition switch to the ON position for one minute. Allow the fuel pump to cycle and prime the system. Turn the ignition switch to the OFF position. 2. Operator must be sitting in the mower seat with both drive control levers in the neutral/start position. 3. Engage the parking brake. 4. Make certain the PTO is in the disengaged (down) position. 5. Place the electronic throttle knob in the START position. 6. Turn the ignition key clockwise to the START position and release it as soon as the engine starts; however, do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start within this time, turn the key to OFF and wait at least 60 seconds to allow the engine's starter motor to cool. Try again after waiting. NOTE: Failure to follow these guidelines can burn out the starter motor. NOTE: Upon start-up, a metallic ticking may occur. Run engine for 5 minutes. If the noise continues, run the engine at the starting position for 20 minutes. If the noise persists, take the mower to your authorized service dealer. Cold Weather Starting When starting the engine at temperatures near or below freezing, ensure the correct viscosity motor oil is used in the engine and the battery is fully charged. Start the engine as follows: 1. Be sure the battery is in good condition. A warm battery has much more starting capacity than a cold battery. 2. Use fresh winter grade fuel. Winter grade gasoline has higher volatility to improve starting. Do not use gasoline left over from summer. 3. Follow the previous instruction for Starting the Engine. Using Jumper Cables to Start Engine WARNING Batteries contain sulfuric acid and produce explosive gases. Make certain the area is well-ventilated, wear gloves and eye protection, and avoid sparks or flames near the battery. If the battery charge is not sufficient to crank the engine, recharge the battery. If a battery charger is unavailable and the mower must be started, the aid of a booster battery will be necessary. Connect the booster battery as follows: 1. Connect one end of the red cable to the disabled mower battery's positive terminal; then connect the other end of that cable to the booster battery's positive terminal. 2. Connect one end of the black cable to the booster battery's negative terminal; then connect the other end of that cable to the frame of the disabled mower, as far from the battery as possible. 3. Start the disabled mower following the normal starting instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection. 4. Have the mower's electrical system checked and repaired as soon as possible to eliminate the need for jump starting. Stopping the Engine 1. Disengage the PTO. 2. Move the RH and LH drive control levers fully outward in the neutral position. 3. Engage the parking brake. 4. Move the throttle to the SLOW about one minute. position and allow the engine to idle for 5. Turn the ignition key to the OFF position and remove the key from the ignition switch. NOTE: Always remove the key from the ignition switch to prevent accidental starting or battery discharge if the equipment is left unattended. 6. Close the fuel shut-off valve(s). Practice Operation (initial use) Operating a zero-turn mower is not like operating a conventional type riding mower. Although and because a zero-turn mower is more maneuverable, getting used to operating the speed control levers and the control levers takes some practice. It is strongly recommended that you locate a reasonably large, level and open "practice area" where there are no obstructions, pedestrians or animals. You should practice operating the mower for a minimum of 30 minutes. Carefully move (or have moved) the mower to the practice area. When performing the practice session, the PTO knob should not be engaged. While practicing, operate the mower at approximately 1/2-3/4 throttle and at less than full speed in both forward and reverse. Always wear appropriate clothing and personal protective equipment (e.g. safety glasses, long pants, gloves, hearing protection, safety shoes, hard hat) when operating or maintaining this machine. Follow all federal, state and local guidelines regarding the use of personal protective equipment. 17
