Safe Operation Practices for Walk-Behind Mowers IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS. FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. Look for this symbol to point out important safety precautions. CAUTION: Always disconnect spark plug wire and place wire where it cannot contact spark plug in order to prevent accidental starting when setting up, transporting, adjusting or making repairs. [. . . ] Do not store, spill or use gasoline near an open flame. Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Empty the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • MOWING TIPS CAUTION: Do not use de-thatcher blade attachments. Such attachments are hazardous, will damage your mower and could void your warranty. Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time. For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly. For better grass bagging and most cutting conditions, the engine speed should be set in the fast position. Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off with water and let dry before using. Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life. • • • • MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE “CLEANING” IN MAINTENANCE SECTION OF THIS MANUAL. TO STOP ENGINE • To stop engine, move throttle control lever to STOP position. Wait until blade and all moving parts have stopped and turn fuel valve to OFF position if you do not intend to restart the engine soon. • TO START ENGINE (See Fig. 14) NOTE: Due to protective coatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal. Be sure fuel valve is in the ON position. To start a cold engine, move handle mounted throttle/ choke control lever to CHOKE position.
