Remember that an authorized Honda servicing dealer knows your
mower best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new, genuine
Honda parts or their equivalents for repair and replacement.
MAINTENANCE SCHEDULE 1. Service more frequently when used in dusty areas.
2. These items should be serviced by an authorized Honda servicing
dealer, unless you have the proper tools and are mechanically
proficient. Refer to the Honda shop manual for service procedures.
Failure to follow this maintenance schedule could result in
non-warrantable failures.
BLADE(S)Inspection
1. Turn the fuel valve to
OFF. Disconnect the
spark plug cap from the
spark plug (page 12).
2. Tilt the mower to the
right, so the air cleaner
side is up. This will help
to prevent fuel leakage
and hard starting.
3. Inspect the blade(s) for
wear and damage.
A dull blade can be sharpened, but a blade that is excessively
worn, bent, cracked, or otherwise damaged must be replaced. A
worn or damaged blade can break, causing blade pieces to be
thrown from the mower.
If the blade(s) are bent, take the lawn mower to an authorized
Honda servicing dealer for inspection.
4. A torque wrench must always be used when installing the blade(s).
Check that the blade bolts are tight.
Removal and Installation
If you remove the blade(s) for sharpening or replacement, you will
need a torque wrench for installation. Wear heavy gloves to protect
your hands.
BLADE SHARPENING: To avoid weakening the blade(s) or causing
imbalance or poor cutting, the blade(s) should be sharpened by
trained staff at an authorized Honda servicing dealer.
BLADE REPLACEMENT: Use genuine Honda replacement blade(s)
or their equivalent (page 18).
Removal
1. Turn the fuel valve OFF. Disconnect the spark plug cap, then tilt the
mower to the right side, so the air cleaner side is up. This will help
to prevent fuel leakage and hard starting due to carburetor
flooding.
2. Remove the two blade bolts with a 14 mm (6 point) socket wrench.
Use a wooden block to prevent the blade(s) from turning when
removing the bolts. Remove the blade(s).
