OPERATION

TO STOP ENGINE

•To stop engine, release operator presence control bar.

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.

1.To start a cold engine, push primer three (3) times before trying to start. Use a fi rm push. This step is not usually necessary when starting an engine which has already run for a few minutes.

2.Hold operator presence control bar down to the handle and pull starter handle quickly.Do not allow starter rope to snap back.

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 fl ood engine, wait a few minutes before attempting to start and do not repeat priming steps.

MOWING TIPS

CAUTION:Do not use de-thatcher blade attachments on your mower. Such at- tachments 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.

•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 fi lled 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 fl ow and extend engine life.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSINGFREEOFBUILT-UPGRASS/TRASH.SEE“CLEANING” IN THE MAINTENANCE SECTION OF THIS MANUAL.

•The special mulching blade will recut the grass clip- pings 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 biode- grade 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.

•Avoid cutting your lawn when it is wet. 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. 13). If the lawn is over- grown 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

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 fi rst 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.
