[. . . ] • TO START ENGINE 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. To start a cold engine, push primer three (3) times before trying to start. This step is not usually necessary when starting an engine which has already run for a few minutes. Hold operator presence control bar down to the handle and pull starter handle quickly. NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps. The special mulching blade will recut 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 recutting action of the blades. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn is the early afternoon. At this time the grass has dried, yet the newly cut area will not be exposed to direct sunlight. 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 (See Fig. If the lawn is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly. MAX 1/3 MOWING TIPS • CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments are hazardous, will damage yourmowerandcouldvoidyourwarranty. • 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. FIG. 13 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. [. . . ] IMPORTANT: Use only Original Equipment Manufacturer (O. E. M. ) replacement parts. Failure to do so could be hazardous, damage your lawn mower and void your warranty.
