3. Tilt the mower to the right side so that the fuel cap side is up. This
will help to prevent fuel leakage and hard starting due to carburetor

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, heavily rusted, 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.
Blade bolt torque:
36 ~ 43 ft-lb (49 ~ 59 N·m)
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 or tightened.
Use only Honda Genuine blade bolts and
special washers, since they are specifically
designed for this purpose. Replacement part
