MAINTENANCE
REMOVAL
1. Turn the fuel valve to the OFF position,
disconnect the spark plug cap, and tilt the
mower on its right side.

washers from the blade holder. Use a wooden
block to prevent the blade from turning when
removing the bolts (P.
3. Clean dirt and grass from around the blade
mounting area.
SHARPENING
NOTICE
Do not sharpen a blade that is damaged or excessively worn or
corroded.
1. Grind or file the blade no more than necessary to remove
nicks and restore straight, sharp cutting edges.
• Always wear eye protection when operating a grinder.
• Wear heavy gloves to protect your hands.
• Grind or file the upper surface of the blade only. The
cutting edge must be even with the lower surface of the
blade.
• Taper the blade profile, removing material from the
blade tip, never the inner end of the cutting surface.
Grinding or filing a step in the blade can create a weak
point, causing cracks to develop in the blade during
mower operation.
• Maintain the original bevel angle (30° ~ 40°) while
sharpening. Do not alter the angle.
• Remove equal amounts of material from both cutting
edges to preserve symmetry and balance.
2. After sharpening, dress the cutting edges with a file so
they will not be razor-sharp. Razor-sharp edges will
easily chip and will quickly become dull.
The blade should be 0.1 ~ 0.3 mm (0.004 ~ 0.012 in) thick
at the cutting edges.
