BLADE REMOVAL AND INSTALLATION

If you remove the blade, use a torque wrench for installation. Wear
heavy gloves to protect your hands. To avoid weakening the blade,
or causing imbalance or poor cutting, the blade should be sharpened
by trained staff at an authorized Honda servicing dealer. If replacing
the blade, use a genuine Honda replacement blade 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 from turning when removing the bolts.
Remove the blade from the blade holder.

3.

Installation:

Clean around the blade holder. Install the blade using

the bolts and special washers exactly (concave side of the special
washers toward the blade) as shown.

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 from
turning.

Blade bolt torque: 49 ~ 59 N
