5.  Fit the new blade, the washer and the bolt back on 
following the same steps in reverse order (Fig. 15).
Storage
Follow the steps below to prepare the lawn mower for storage:
1.  Disconnect the power supply to the mower. 
2.  Clean the mower with a damp cloth or hand brush.
3.  Inspect the 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 and Care section.
4.  Store the 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 mower, which 
can damage the unit.
8.  The handle on your lawn mower can be folded for 
compact storage. Start by loosening the handle knobs on 
each side of the upper handle and fold down the upper 
handle (Fig. 16).
