A dull blade can be sharpened, but a blade that is excessively
worn, bent, cracked, or otherwise damaged must be replaced.
If a blade is bent, take the lawn mower to an authorized Honda
servicing dealer for inspection.
Blade Mounting Bolt Inspection
Inspect the blade bolts for any signs of damage
or looseness. If they are damaged, they must
be replaced.
If the bolts appear loose, a torque wrench must
be used to accurately tighten the blade bolts to
the required torque. If you do not have a torque
wrench, take your lawn mower to an authorized
dealer to have the bolts replaced and/or
tightened.
Use only Honda Genuine blade bolts and
special washers, since they are specifically
designed for this purpose.
Replacement part numbers are on page 21.
Blade Replacement
1. Turn the fuel valve OFF (page 3).
2. Disconnect the spark plug cap from the spark plug (page 14).
3. Tilt the mower to the right side, so the fuel cap side is up. This will
help to prevent fuel leakage and hard starting due to carburetor
flooding.
4. Remove the blade bolts with a 14 mm (6 point) socket wrench.
Wear thick leather gloves and hold the blades with your hand to
prevent the blades from turning when removing the bolts.
Remove the blades.
5. Inspect the blade holder and blade mounting surface for damage.
If damage is found or the blades have impacted a hard object, the
blade holder should also be replaced.
6. Clean dirt and grass from around the blade mounting area.
7. Install the sharpened or replacement blades using the blade bolts
and special washers as shown.
Always install both blades as a set.
The blade bolts and washers are specially designed for this
application. When replacing the bolts and washers, use only
Honda Genuine replacement parts.
8. Tighten the blade bolts with a torque wrench. Wear thick leather
gloves and hold the blades with your hand to prevent the blades
from turning when tightening the bolts, as shown below.
Blade bolt torque: 36 ~ 43 ft-lb (49 ~ 59 N·m)
If you do not have a torque wrench, have an authorized Honda
servicing dealer tighten the blade bolts.
WARNING
A worn, cracked, or damaged blade can break, and pieces of
the damaged blade can become dangerous projectiles.
Blades thrown from the mower could seriously hurt or kill
someone.
Inspect the blades regularly, and do not operate the mower
with worn or damaged blades.
