Troubleshooting - Honda HRS536SDE Owner's Manual

BLADE REMOVAL AND INSTALLATION
If you remove the blade 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 blade, or causing
imbalance or poor cutting, the blade should be sharpened by trained
staff at an authorized Honda dealer.
BLADE REPLACEMENT: Use a Honda Genuine replacement blade
or its equivalent.
Blade Removal
1. Turn the fuel valve OFF. Disconnect the spark plug cap, and then
tilt the mower to the right side so that the air cleaner side is up.
This will help to prevent fuel leakage and hard starting due to
carburetor flooding.

2. Use a 14 mm (6 point) socket wrench and remove the two blade
bolts [1] and special washers [2] from the blade holder [3]. Use a
wooden block to prevent the blade from turning when removing the
bolts.
3. Remove the blade [4].
Blade Installation
1. Clean dirt and grass from around the blade mounting area. Install
the blade [4] using the two blade bolts [1] and special washers [2].
Be sure to install the special washers with the concave side toward
the blade and the convex side toward the head of the bolt.
The blade bolts are specially designed for this application and
must not be replaced with other bolts.
2. Tighten the blade bolts with a torque wrench. Use a wooden block
to prevent the blade from turning.
Blade bolt torque: 49 ~ 59 N·m
If you do not have a torque wrench, have an authorized Honda
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 to fly off while you are
operating the mower.
