SERVICING YOUR LAWN MOWER
Blade Removal and Installation
If you remove the blades for sharpening or replacement, you will need
a torque wrench for installation. Wear heavy gloves to protect your
hands.
BLADE SHARPENING: To avoid weakening the blades, or causing
imbalance or poor cutting, the blades should be sharpened by trained
staff at an authorized Honda servicing dealer.
BLADE REPLACEMENT: Use genuine Honda replacement blades or
their equivalent (page 73).
Blade Removal
1. Turn the fuel valve OFF. Disconnect the spark plug cap (see
page 42), then tilt the mower to the right side, so the carburetor
side is up. This will help to prevent fuel leakage and hard starting
due to carburetor flooding.
2. Remove the two blade bolts with a 14 mm socket wrench. Use a
wooden block to prevent the blades from turning when removing
the bolts. Remove the blades.
