9. MAINTENANCE BLADE REMOVAL AND INSTALLATION
When the blade needs sharpening or replacement, take the lawn mower to
an authorized Honda lawn mower dealer. Or, if you have a torque wrench, you
can remove and install the blade yourself. Wear heavy gloves to protect your
hands.
Blade sharpening: To reduce the possibility of weakening the blade, or causing
imbalance or poor cutting performance, have the blade sharpened by an
authorized Honda lawn mower dealer.
Blade replacement: Install a genuine Honda replacement blade or its equivalent.
Use the standard HRM21 low-lift blade for mulching. Use the optional high-
lift HRM21 blade for side-discharge mowing or bagging.
Blade Removal 2
1. Turn the fuel valve OFF, and rest the mower on its left side, so the carburetor
side is up.
NOTE: hard starting and fuel leakage may result if the mower is placed with
the carburetor side down.
2. Remove the two blade nuts with a 17 mm socket wrench. Use a wooden
block to prevent the blade from turning when removing nuts.
3. Remove the blade from the blade holder.
