SERVICING YOUR LAWN MOWER

Blade Installation
1. Clean dirt and grass from around the blade mounting area.
2. Install the blades using the two blade bolts and special washers as
shown. Be sure to install the special washers with the concave side
toward the blades and the convex side toward the bolts.
The blade bolts and washers are specially designed for this
application. When replacing bolts and washers, use only genuine
Honda replacement parts.
3. Finger tighten the blade bolts until both blades are secured on the
blade holder. Make sure that the bolt holes on the upper blade are
fully seated over the locator pins.
If the blades are not fully seated on the locator pins, they will cause
excessive vibration and damage your lawn mower. Do not continue
to run the engine if you notice excessive vibration. Re-check the
positioning of the blades.
4. With the blades properly seated, hold the blades so they cannot
rotate and tighten the bolts with a torque wrench.
Blade bolt torque: 36 ~ 43 ft-lb; 5.0 ~ 6.0 kg-m (49 ~ 59 N·m)
If you do not 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 blades to fly off while you
are operating the mower.
5. Install the spark plug cap on the spark plug.
