1. Stop motor and wait for all moving parts to stop.
Remove the key from the plug.
2. Tip mower on its side.
3. EXAMINING BLADE – Carefully examine blade for
sharpness and wear, especially where flat and curved
parts meet (Fig. 24A). Since sand and abrasive
material can wear away the metal that connects the flat
and curved parts of the blade, check blade before using
the mower. If a slot or wear is noticed (Fig. 24B &
24C), replace blade. Refer to step 4.

Note: For best performance, install new blade before
cutting season begins. During the year, file down small
nicks to maintain the cutting edge.

and blade (Fig. 25).

2. Washer
5. SHARPENING BLADE – Using a file, sharpen top
side of blade and maintain original cutting angle
(Fig. 26). The blade will remain balanced if same
amount of material is removed from both cutting
edges.
IMPORTANT: Check balance of blade by putting it on
a blade balancer. An inexpensive balancer can be
purchased at a hardware store. A balanced blade stays
in a horizontal position and an unbalanced blade settles
to the heavy side. If blade is not balanced, file more
metal off cutting edge on heavy end of blade.

1. Sharpen at this angle only
6. Reinstall sharp, balanced blade, washer and blade bolt.
Sail part of blade must point toward top of mower
housing to ensure correct installation. Washer is
curved and must be reinstalled with curve side down
as shown in (Fig. 25). Tighten blade bolt to 35-40 ft-lb
(48-54 N m).
