MOWER SAFETY
IMPORTANT SAFEN INFORMATION
Most accidents with walk-behind mowers can be prevented if you
follow all instructions in this manual and on the mower. The most
common hazards, according to accident statistics, are discussed
below, along with the best way to protect yourself and others.
Avoid Rotating Blades
Rotating blades can cause serious cuts and even amputate fingers,
hands, toes, or feet. Keep away from the mower deck whenever the
engine is running. If you need to adjust the cutting height, or work
around the deck for any other reason, always shut off the engine.
Wear heavy gloves and disconnect the spark plug cap when you
need to clean the mower deck or handle the blade(s).
Clear Mowing Area
Mower blades can throw rocks and other objects with enough force to
cause serious injury. Before mowing, carefully inspect the area and
remove all sticks, stones, pieces of wire, and other loose objects.
Never operate the blade(s) over gravel.
Keep Shields in Place
Guards and shields are designed to protect you from being hit by
thrown objects and from hot engine parts and moving components.
For your safety and the safety of others, keep all shields in place
when the engine is running.
Refuel with Care
Gasoline is extremely flammable and gasoline vapor can explode.
Refuel only outdoors, in a well-ventilated area, with the engine OFF.
Never smoke near gasoline, and keep other flames and sparks away.
Always store gasoline in an approved container.
Wear Protective Clothing
Wearing protective clothing will reduce your risk of injury. Long pants
and eye protection reduce the risk of injuries from thrown objects.
Sturdy shoes with aggressive soles will help protect your feet and
give you better traction on slopes or uneven ground.
Turn Engine Off When Not Mowing
If you need to leave the mower for any reason, even just to inspect
the lawn ahead, always turn the engine OFF.

MOWER SAFETY
IMPORTANT MESSAGE TO PARENTS
YOUR CHILDREN’S SAFETY IS VERY IMPORTANT to Honda.
That’s why we urge you to read this message before letting your
youngster operate this lawn mower. Lawn mowers are tools, not toys.
As with any equipment, bad judgments can result in serious injuries.
You can help prevent accidents by making good decisions about if,
when, and how your youngster operates this equipment.
The first question you’ll need to ask is whether your youngster is
capable of operating this mower safely. Remember, young people
vary widely, and AGE IS NOT THE ONLY FACTOR.
Physically, a youngster must be LARGE ENOUGH AND STRONG
ENOUGH to easily start the mower and control its direction. The
youngster also needs enough size, strength, and coordination to
comfortably reach and operate the controls.
Another, tougher question you need to ask is if your youngster has
enough MATURITY AND RESPONSIBILITY to safely operate this
mower. Does the young person think through problems and come to
logical solutions? Be honest! Anyone who takes unnecessary risks
and doesn’t obey rules should not operate this lawn mower.
If you decide that your son or daughter can handle the mower safely,
CAREFULLY READ THE OWNER’S MANUAL with your youngster.
Make sure you both understand all instructions and safety
information. Also, be sure your youngster wears sturdy shoes and
other protective clothing when operating or handling the mower.
SUPERVISION is also very important. Walk with your youngster
during the first few minutes of mowing. Even after the youngster has
become confident with the mower, do not let the young person use
the mower without good adult supervision. An adult should also be
present during refueling and maintenance. In fact, it’s up to parents to
make sure that the mower is properly maintained and kept in safe
operating condition.
By always placing safety first, your youngster will acquire useful skills
and a sense of accomplishment. And you’ll both get the best results
from your lawn mower.

BEFORE OPERATION
ARE YOU READY TO MOW?
Be sure to wear protective clothing. Long pants and eye protection
can lower your risk of injury from thrown objects. Wear footwear that
protects your feet and won’t let you slip if you mow on slopes or
uneven ground.
CHECK YOUR LAWN
For your safety and for the safety of others, always inspect the area
before mowing.
Objects
Anything which can be picked up by the blade(s) and thrown is a
potential hazard to you and others. Look for things like stones, sticks,
bones, and wire. Remove them from the mowing area.
People and Pets
People and animals near the mowing area can move into your path or
into a position where they could be struck by thrown objects. Clear
the area of people and pets, especially children. Their safety is your
responsibility.
Lawn
Check the length and condition of the grass, so you will know what
cutting height and mowing speed to use.
Avoid mowing wet grass. Not only will wet grass clog your mower
deck and collect in clumps on the lawn, it also gives poor traction,
increasing your risk of losing your footing.
16
CHECK YOUR MOWER
Rh
Blade(s)
1. Turn the engine OFF and turn
the fuel valve to the OFF
position (see page 31).
2. Disconnect the spark plug cap
from the spark plug (see page 48).
3. Tilt the mower to the right, so
the carburetor side is up. This
will help to prevent fuel leakage
and hard starting.
4. Inspect blade(s) for wear and damage.
A worn, cracked, or damaged blade can
break, and pieces of the damaged blade can
become dangerous projectiles.
Thrown objects can cause serious injury.
BLADE B
BEFORE OPERATION
BLADE(S)
Inspect the blade regularly, and do not
operate the mower with a worn or damaged
blade.
hl I-J U
NORMAL
A dull blade can be sharpened, but a blade that is worn out, bent,
cracked, or otherwise damaged must be replaced. A worn or damaged
blade can break, causing blade pieces to be thrown from the mower.
When a blade needs sharpening or replacement take the lawn mower
to an authorized Honda servicing dealer. Or, if you have a torque wrench,
you can remove and install the blade(s) yourself (see pages 56 - 57).
Check that the blade bolts are tight (see page 57).

BEFORE OPERATION
Engine Oil Level
Check the engine oil level with the engine stopped and the mower on
a level surface.
1. Remove the oil filler cap, and
wipe the dipstick clean.
2. Insert and remove the dipstick
without screwing it into the filler
neck. Check the oil level shown
on the dipstick.
FILLER CAP/DIPSTICK
3. If the oil level is low, add the
recommended oil (see page
46) to reach the upper limit
mark on the dipstick. Do not
overfill.
4. After checking the engine oil
level, screw in the filler
cap/dipstick securely.

Fuel
Fuel tank capacity: 0.26 US gal (1.0 t)
Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Refer to page 51 for fuel
recommendations and page 85 for information about oxygenated
fuels.
Remove the fuel tank cap and check the fuel level. Refill the tank if
the fuel level is low. Refuel carefully to avoid spilling fuel. Do not
overfill; there should be no fuel in the filler neck. After refueling,
tighten the fuel tank cap securely.
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when
handling fuel.
l Stop the engine and keep heat, sparks,
and flame away.
l Handle fuel only outdoors.
l Wipe up spills immediately.
Never refuel the mower inside a building where gasoline fumes may
reach flames or sparks. Keep gasoline away from appliance pilot
lights, barbecues, electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental damage.
Wipe up spills immediately.

BEFORE OPERATION
Grass Bag (HRB215)
A lawn mower works like a vacuum cleaner; it blows air through the
bag, which traps the grass clippings. Always empty the grass bag
before it becomes filled to the limit of its capacity. Bagging
performance will diminish after the bag becomes about 90% filled.
Also, the bag is easier to empty when it is not packed full.
Inspection
Inspect the grass bag for tears, holes, and excessive wear. The grass
bag wears during normal use and will eventually require replacement.
Grass bag replacement is explained on page 58.
Installation
1. Raise the discharge guard, and
hook the grass bag onto the
mower deck as shown.
DISCHARGE GUARD
2. Release the discharge guard to
secure the grass bag.
Removal
1. Raise the discharge guard,
grasp the grass bag handle
and remove the grass bag.
2. Release the discharge guard.
3. When the grass bag is clear of
the discharge guard, you can
lift it through the handlebar
opening, or you can remove it
to the rear of the mower below
the handlebar.
22
HANDL
Mulching Plug
The mulching plug contours the
mower deck for efficient mulching.
Raise the discharge guard to
remove or install the mulching
plug. When installing, be sure the
plug is fully inserted, and the
discharge guard is closed.
DISCHARGE GUARD
Cutting Height
Bagging or Side-Discharge*
(all models): Move all four levers
to the same position.
Mulching (HRM): Move all four
levers to the same position.
Mulching (HRB): Move the front
levers one position higher than
the rear levers.
To adjust cutting height, pull each
adjustment lever toward the
wheel, and move it into another
notch.
If you are not sure what cutting
height to select, start with a high
setting and check the appearance
of the lawn after mowing a small
area. Then readjust cutting height
if necessary.

OPERATION
MOWING PRECAUTIONS
Before operating the mower for the first time, please review the
IMPORTANT SAFETY INFORMATION beginning on page 6 and the
previous chapter, titled BEFORE OPERATION.
Even if you have operated other mowers, take time to become
familiar with how this mower works and practice in a safe area until
you build up your skills.
For your safety, avoid starting or operating the engine in an enclosed
area such as a garage. Your mower’s exhaust contains poisonous
carbon monoxide gas which can collect rapidly in an enclosed area
and cause illness or death.
