Hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter 8 robe to snap back. MOWINGTIPS 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. • The special mulching blade will recur the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recurring action of the blades. • Avoid cutting your lawn when it is wet. Wet grass tends to form clumps and interferes with the mulching acflon. The best time to mow your lawn is the eady afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. • For best results, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades. If the lawn Is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from ovedoading the engine and leaving clumps of mu_ched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly. • 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 or perpendicular to the first cut path. • Change your cutting pattem 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. • Under corta'm conditions, such as very tail 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 positiwn. • For side discharge lawn mowers, cutting in a counter-clockwisa direction, starting at the outside of the area to be cut, spreads grass clippings more evenly and puts less load on the engine. To keep clippings off of walkways, flower beds, etc., make the first cuts in a clockwise direction. • Pores in cloth grass catchers can become filled with dirt and dust with usa 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.

NOTE: If alter cleaning, the ddve wheels do not turn freely, contact your nearest authorized service center. GEAR CASE • To keep your ddve system working properly, the gear case and area around the ddve should be kept clean and free of trash build-up. Clean under the drive cover twice a season. • The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after"every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level. TO CHANGE ENGINE OIL NOTE: Before tipping lawn mower to drain oil, drain fuel tank by running engine until fuel tank is empty. 1.
