BLADE REMOVAL AND INSTALLATION

If you remove the blade(s), use a torque wrench for installation. Wear
heavy gloves to protect your hands. 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. If replacing the
blade, use a genuine Honda replacement blade(s) or equivalent.
1. Removal: Turn the fuel valve to OFF. Disconnect the spark plug
cap, then tilt the mower to the right side, carburetor side up.
2. Remove the two blade bolts with a 14 mm socket. Use a wooden
block to prevent the blade(s) from turning when removing the bolts.
Remove the blade(s) from the blade holder.
3. Installation: Clean around the blade holder. Install the blade(s)
using the bolts and special washers as shown (concave side of the
special washers toward the blade(s)).
The blade bolts and washers are specially designed; when
replacing them, use only genuine Honda parts. Tighten the bolts
with a torque wrench. Use a wooden block to stop the blade(s)
from turning.
Blade bolt torque: 36 ~ 43 ft-lb (49 ~ 59 N m)
If you don't have a torque wrench, have an authorized Honda
servicing dealer tighten the blade bolts before you use the mower.
If the blade bolts are overtightened, they could break. If the blade
bolts are not tightened enough, they could loosen or come out. In
either case, it would be possible for the blade(s) to fly off while you
are operating the mower.
