Use and Care Guide
5.  Fit the new blade, the washer and the bolt back on 
following the same steps in reverse order (Fig. 16).
Storage
Follow the steps below to prepare the lawn mower for storage:
1.  Disconnect the power supply to the lawn mower. 
2.  Clean the lawn mower with a damp cloth or hand brush.
3.  Inspect the lawn mower carefully for worn, loose, or 
damaged parts. Check connections and screws and 
tighten if necessary. Pay special attention to the mower 
blade and replace/sharpen if it shows signs of wear. Refer 
to the Maintenance section.
4.  Store the lawn mower indoors in a dry, clean, and cool 
area out of the reach of children. Do not store the unit next 
to corrosive materials, such as fertilizer and rock salt.
5.  Wipe the extension cord to remove any foreign 
substances, such as oil or stains. Replace the extension 
cord immediately if it is cut or damaged in any way.
6.  Wind the cord in a series of equal loops to prevent it 
from tangling.
7.  Do not cover the lawn mower with a solid plastic sheet. 
Plastic coverings trap moisture around the lawn mower, 
which can damage the unit.
