MOWER BLADE SHARPENING
Inspect the mower blades before each use to be
sure they are properly installed and are in good
condition. Replace any blade that is bent,
cracked, excessively nicked or worn. Use only
genuine SHIBAURA blades on this mower.
WARNING
To avoid injury when handling blades, wear
leather gloves or wrap the blades in the area
where they will be held with heavy cloth or
other protective material. Always wear eye
protection when sharpening blades.
IMPORTANT: When sharpening blades, remove
the same amount of material from each blade to
maintain balance. Unbalanced blades will cause
excessive vibration, which could damage
gearbox and mower components.
1. Use a mill file or grinder to sharpen the
blades following the original 45° angle
pattern. If using a grinder, use care so the
cutting edge does not get too hot from
friction, causing it to lose its heat treat.
IMPORTANT: DO NOT sharpen cutting edge to
a razor edge. Leave a 0.8 mm edge as shown.
2. Check the blade for balance by placing a
horizontal rod with an O.D. less than 16 mm,
in a vise.
3. Place the blade on the rod. The heavy side
of the blade should drop down.
4. Sharpen on the heavy side of the blade until
the blade remains balanced on the rod.
