SAFETY RULES 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. I. GENERAL OPERATION • Read, understand, and follow all instructions on the machine and in the manual(s) before starting. [. . . ] 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. MAX 1/3 • • • FIG. 10 • Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut, mow across (perpendicular) to the first cut path. Change your cutting pattern from week to week. Mow north to south one week then change to east to west the next week. This will help prevent matting and graining of the lawn. • • 9 MAINTENANCE BEFORE EACH USE Check for Loose Fasteners Clean / Inspect Grass Catcher * Check Tires Check Drive Wheels *** Clean Lawn Mower **** Clean under Drive Cover *** Check Drive Belt / Pulleys *** Check / Sharpen / Replace Blade Lubrication Clean and Recharge Battery ** Check Engine Oil level Change Engine Oil Clean Air Filter Inspect Muffler Replace Spark Plug Replace Air Filter Paper Cartridge Empty fuel system or add Stabilizer AFTER EACH USE EVERY 10 HOURS EVERY 25 HOURS OR SEASON EVERY 100 HOURS BEFORE STORAGE * (if so equipped) ** Electric-Start mowers *** Power-Propelled mowers **** Use a scraper deck to clean under 1 - Change more often if operating under a heavy load or in high outdoor temperatures. 2 - Service more often if operating in dirty or dusty conditions. 3 - Replace blades more often when mowing in sandy soil. 5 - And after each 5 hours of use.
