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.
