• 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
Perform at every indicated month/year or operating hour interval,
whichever comes first.
1. Service more frequently when used in dusty areas.
2. See the FAQ section of the Honda Power Equipment web site at
www.hondapowerequipment.com/faq for more information.
3. 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.
4. The HMA model requires the battery to be charged for
20~24 hours before and after winter storage.
Failure to follow this maintenance schedule could result in
non-warrantable failures.
BLADES
Inspection
1. Move the fuel valve to the OFF position (page 8) and disconnect
the spark plug cap from the spark plug (page 13).
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.
