• Read the instructions before you begin, and make sure you have
the tools and skills required.
• To reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a nonflammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks, and flames away
from all fuel-related parts.
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.
BLADES

Inspection

1. Move the fuel valve to the OFF
position (page 7) and
disconnect the spark plug cap
from the spark plug (page 12).
2. Tilt the mower to the right so the
fuel cap is up. This will help
prevent fuel leakage, motor oil
seeping into the air filter and
hard starting.
3. Inspect the blades for damage, cracks, and excessive wear, rust,
or corrosion.
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 a blade is bent, take the lawn mower to an authorized Honda
servicing dealer for inspection.
4. Always use a torque wrench when installing the blades. Check that
the blade bolts are tight.

Blade Removal and Installation

If you remove the blades 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 blades or causing
imbalance or poor cutting, the blades should be sharpened by trained
staff at an authorized Honda servicing dealer.
BLADE REPLACEMENT: Use Honda Genuine replacement blades or
their equivalent (page 18).
