Gasoline and Oil Recommended Gasoline Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. WHAT CAN HAPPEN IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
Gasoline and Oil Stabilizer/Conditioner Filling the Fuel Tank Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine: 1. Shut the engine off and set the parking brake. 2. Clean around each fuel tank cap and remove the cap. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand.
Operation Think Safety First Parking Brake Please carefully read all the safety instructions and symbols in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Always set the parking brake when you stop the machine or leave it unattended. Setting the Parking Brake Controls Become familiar with all the controls (Fig. 1) before you start the engine and operate the machine. 1. Push the brake pedal (Fig. 2) down and hold it in the depressed position.
Operation Positioning the Seat Using the Blade Control (PTO) The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. The blade control (PTO) engages and disengages power to the blade(s). 1. Engaging the Blade(s) 2. Raise the seat and loosen the adjustment knob (Fig. 3). Move the seat to the desired position and tighten the knob. 1. Depress the brake pedal to stop the machine. 2.
Operation Setting the Height-of-Cut 5. Turn the ignition key clockwise and hold it in the “START” position (Fig. 8). When the engine starts, release the key. The height-of-cut lever (deck lift) is used to raise and lower the mower to the desired cutting height. 1. The cutting height may be set in one of seven positions from approximately 1 to 4 inches (25 to 102 mm). 2. Pull on the height-of-cut lever (deck lift) and move it to the desired position (Fig. 5).
Operation The Safety Interlock System Stopping 1. Move the throttle lever to “SLOW” (Fig. 7). 2. Turn the ignition key to “OFF” (Fig. 8). Note: If the engine has been working hard or is hot, let it idle for a minute before turning the ignition key “OFF.” This helps cool the engine before it is stopped. In an emergency, the engine may be stopped by turning the ignition key to “OFF.
Operation Operating–in–Reverse An interlock feature is provided that prevents the Power Take Off (PTO) from operating while the tractor is traveling in reverse. If the unit is shifted into reverse while the mower blade or other PTO driven attachment is engaged, the engine will stop. Do not mow while backing up unless it is absolutely necessary.
Operation Testing the Safety System Test the safety system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. While setting in the seat, perform the following checks. 1 1. Move the ground speed selector into neutral “N.” Set the parking brake. Move the blade control (PTO) to “ENGAGED.” Now turn the ignition key to “START”; the engine should not crank. 2.
