[. . . ] 5521RS Owner’s Manual 532 18 72-39 Rev. 1 07. 28. 04 BY Printed in U. S. A. 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. [. . . ] 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 ON ( ) OFF ON • FUEL VALVE LEVER • FIG. 14 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 east to west the next week. This will help prevent matting and graining of the lawn.
