Installation

1. Clean dirt and grass from around the blade mounting area.
2. Install the blade(s) using the two blade bolts and special washers
as shown. Be sure to install the special washers with the concave
side toward the blade(s) 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 Honda
Genuine replacement parts.
3. Tighten the blade bolts with a torque wrench. Use a wooden block
to prevent the blade(s) from turning when tightening the bolts.
Blade bolt torque: 36 ~ 43 ft-lb (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 blade(s) to fly off while you
are operating the mower.
GRASS BAG CLEANING AND REPLACEMENT (HRR)

Cleaning

Wash the bag with a garden hose, and allow it to dry completely
before use; a wet bag will clog quickly.

Replacement

Replace a worn or damaged bag with a Honda replacement bag or its
equivalent (page 19).
Removal
1. Unclip the plastic edges of
the bag from the frame.
2. Remove the frame from
the bag.
Installation
1. Insert the frame into the
bag, as shown.
2. Clip the plastic edges of
the bag onto the frame, as
shown.
ENGINE MAINTENANCE

Engine Oil Level Check

1. Unscrew and remove the filler cap/dipstick and wipe it clean.
2. Insert and remove the
dipstick without
screwing it into the filler
neck. Check the oil level
shown on the dipstick.
3. If the oil level is low, add
oil to reach the upper limit
mark on the dipstick. Do
not overfill. If the engine
is overfilled, the excess
oil may get transferred to
the air cleaner housing
and air cleaner filter.
NOTICE
Running the engine with
a low oil level can cause
engine damage.
4. Screw in the filler
cap/dipstick securely.

Engine Oil Recommendations

Oil is a major factor affecting performance and service life. Use
4-stroke automotive detergent oil.
Always change the oil in accordance with the MAINTENANCE
SCHEDULE (page 9).
SAE 10W-30 is recommended for
general use. Other viscosities
shown in the chart may be used
when the average temperature in
your area is within the
recommended range.
The SAE oil viscosity and service
classification are in the API label
on the oil container. Honda recommends API service category SJ or
later oil.
B WARNING
Operating the HRR mower with only one blade will result in
an improperly seated blade that can be thrown from the
mower and seriously hurt or kill someone.
Always install both blades as a set.
