4. INSPECTING BLADE—Carefully examine
blade for sharpness and wear, especially where
flat and curved parts meet (Fig. 25A). 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. 25B & C), replace
blade. Refer to step 5.
