nut (1) “COUNTERCLOCKWISE” to loosen it and

Remove the blade nut (1), the square washer (2), and 
the blade (3).

To re-install the blade, position the blade with the 
cutting edges toward the ground and align the blade 
on the alignment tabs (one round and one semi-round). 

NOTE: 

The blade can only be placed one way for a 

proper and correct fit. Assemble the balde, the square 
washer and the blade nut as shown in the following. 
Using a 15-mm wrench or socket, turn the blade nut 
“CLOCKWISE” to secure the blade.

NOTE:

 Be sure to replace the parts in the exact order in which 

they were removed. When installing the cutting blade, verify 
that it is installed with the curved ends pointing toward the 
mower deck.

Cleaning the Mower 

m

 WARNING:

 

To reduce the risk of electric shock, do not 

expose the mower to water.
The underside of mower deck should be cleaned after each 
use as grass clippings, leaves, dirt and other debris will 
accumulate causing rust and corrosion.
Remove any buildup of grass and leaves on or around the 
motor cover (do not use water). Wipe the mower clean with a
dry cloth occasionally.

• If debris build up on the underside of the unit while using, 

stop the motor and disconnect it from the power supply. 
Tilt the mower forward, or on its side, and scrape it clean 
with an appropriate tool.

Storage

The following steps should be taken to prepare the lawn 
mower for storage.

• Make certain the power cord is disconnected.
• Clean mower as instructed in previous section.
• Inspect and replace or sharpen blade. Refer to the 

Maintenance section.

• Store mower in a dry, clean area. Do not store next to 

corrosive materials, such as fertilizer or rock salt.

• Store mower indoors, in a cool, dry place, out of reach 

of children. Do not cover lawn mower with a solid plastic 
sheet. Plastic coverings trap moisture around the mower 
causing corrosion.

• The handle may be folded away completely for storage.
• Loosen the handle knobs on the sides of the handles, and 

fold the upper handle down.

• Loosen the handle knobs, pull outwards on each side of 

the lower handle, and lift the sides of the lower handle 
past the edges of the handle mounting brackets. Fold the 
lower handle forward. Make sure not to bend or kink the 
power cord.
