Maintenance 3. Reassemble the grass collection bag to the mower body.
Mowing TipsmWARNING! Inspect the area prior to mowing andremove all the stones, sticks, wires, and other debris that might be thrown by the rotating blade.NOTE: A sharp blade will greatly enhance the performance of the lawn mower, especially when cutting tall blades of grass.· Be sure to check the blade periodically for signs of wear and sharpen it at least once per year, as described in the maintenance section.· In order to prevent electric shock, do not operate the lawn mower in damp or wet conditions.· Do not mow in a circle. Travel back and forth across the lawn following the path outlined below (Fig. 15).· When cutting thick grass, reduce your walking speed in order to allow for a more effective cut and a proper discharge of the clippings. For a healthy lawn, always cut off one-third or less from the total length of the grass. The average lawn should be approximately 1.5 in. to 2 in. (3.8 cm to 5 cm) long during cool months, and more than 2 in. (5 cm) long during hot months. If there is growth, the lawn should be cut in the fall.Fig. 15
