Throttle Control The throttle lever changes the speed of the engine. Move the throttle lever to FAST (rabbit) to increase engine speed. Move the lever to SLOW (turtle) to decrease engine speed. Operator Presence Levers The operator presence control lever must be pressed to operate the PTO or traction drive. When the shift lever or PTO is engaged, releasing the operator presence control lever stops the engine. Choke Control Use the choke control to start a cold engine. Pull the control out to choke the engine. Push the control in when the engine gets warm. Shift Lever The shift lever sets the direction and speed of the unit. R = Reverse N = Neutral = the slowest forward speed = the fastest forward speed. PTO Clutch Pull the PTO (power take off) switch UP to engage the mower blades. Push the PTO switch DOWN to disengage the mower blades. Service Meter Measures the number of hours the engine has been run. Recoil Starter Grip Pull the recoil starter handle to start the engine. WARNING! Fuel is highly flammable and its vapors are explosive. Handle with care. Use an approved fuel container. NO smoking, NO sparks, NO flames. ALWAYS allow engine to cool before servicing. NEVER fill fuel tank when engine is running or hot from operation. NEVER fill or drain fuel tank indoors. Replace fuel cap securely and clean up spilled fuel. Fuel Tank Use regular grade unleaded fuel with an octane rating of 87 octane or higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE reformulated fuel are acceptable. Do not use fuel or additives containing methanol as engine damage can occur. Always use fresh, clean fuel that is purchased in a quantity that can be used within approximately 30 days, or add fuel stabilizer. Fuel is blended to give best seasonal performance. To avoid engine performance problems such as hard starting or vapor lock, use in-season fuel. Use fuel during warm weather that was purchased during that season, and use fuel during cold weather that was purchased during that season. Fuel can become stale in machines with engines that are used seasonally or infrequently during a season. Stale fuel can produce varnish and plug carburetor components which can affect engine performance. Keep fuel storage container tightly covered and in a cool area out of direct sunlight. Fuel can break down and degrade if not sealed properly or exposed to sun and heat. Condensation may collect in the fuel tank because of a variety of operating or environmental conditions and, over time, may affect your machine's operation. Fill fuel tank at the end of daily use and store fuel in plastic containers to reduce condensation. For best year-round performance and fuel handling, add stabilizer to fuel immediately after fuel purchase. Such practice helps prevent engine performance problems and allows fuel storage in the machine all year without draining. Adding fuel 1. Move the unit to an open area. 2. Stop the engine and allow engine to cool. 3. Clean the fuel cap and the area around the fuel cap to prevent dirt from entering the fuel tank. 4. Remove the cap from the fuel tank and fill the fuel tank. Do not overfill. Avoid spills. 5. Reinstall the cap on the fuel tank and tighten. 6. Clean up any spilled fuel before starting the engine. - 13 -
