Lawn Mower User Manual

Blade Inspection
1. Turn the fuel valve OFF (page 3).
2. Disconnect the spark plug cap from the spark plug (page 13).
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. Inspect the blades for damage, cracks, and excessive rust or
corrosion.
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 they 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 20.
Blade Replacement
1. Remove the two blade bolts with a 14 mm (6 point) socket
wrench. Use a wooden block to prevent the blades from turning
when removing the bolts. Remove the blades.
2. Clean dirt and grass from around the blade mounting area.
3. Install the sharpened or replacement blades using the two blade
bolts and special washers as shown below.
The blade bolts and washers are specially designed for this
application. When replacing bolts and washers, use only Honda
Genuine replacement parts.
4. Tighten the blade bolts with a torque wrench. Use a wooden
block to prevent the blades from turning when tightening the
bolts, as shown on page 12.
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.
Thrown objects can cause serious injury.
Inspect the blades regularly, and do not operate the mower
with worn or damaged blades.
