MOWER SAFETY
Safety 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 work around the
deck to clear grass accumulation, adjust the cutting height, or for
any other reason, always shut off the engine. Disconnect the
spark plug cap from the spark plug. Wear heavy gloves 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.
2
MOWER SAFETY
Keep Shields in Place
Guards and shields are designed to protect you from being hit by
thrown objects and from touching 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. If the engine has been running, allow it to cool.
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.

BLADES AND ATTACHMENTS
Blades
HRB215
HRB215 mowers are factory equipped with a high-lift blade for
maximum bagging and side-discharge performance.
ONE-PIECE HIGH-LIFT BLADE
(standard for HRB215, optional for HRM215)
l Best for bagging and side-discharge.
l Less effective for mulching.
HRM215
HRM215 mowers are factory-equipped with a special two-piece
mulching blade assembly.
With the mulching plug installed (page 9), the two blades
recirculate cut grass under the mower deck, where the clippings
are chopped into small particles that fall through the turf and
decompose quickly. This returns nutrients to the soil and ‘reduces
the need for raking, bagging, and disposal.
0
When the mulching plug is removed, and the optional grass bag
or side-discharge chute is installed, the blades blow cut grass
into the bag or out the side-discharge chute.
It is not necessary to change blades when switching between
mulching, bagging, and side-discharge operation. The mulching
blades perform all three functions.
TWO-PIECE MULCHING BLADE ASSEMBLY.
(standard for HRMPlS, optional for HRB215)
l Best for mulching.
l OK for bagging and side-discharge.
8
BLADES AND ATTACHMENTS
Grass Bag (standard for HRB215, optional for HRM215)
With the grass bag installed, the
lawn mower works like a
vacuum cleaner. It blows air
through the bag, which traps the
clippings.
Bagging should be considered
B
where you want the lawn to be
clear of loose particles, such as
around swimming pools.
Bagging is also a good way to
deal with less frequently mowed
areas where the grass has
grown too tall to mulch easily.
To attach the grass bag, lift the
discharge guard, (remove the
mulching plug if so equipped),
and hook the bag onto the
mower deck as shown. Release
the discharge guard to secure
the grass bag.
Mulching Plug (standard for HRM215, optional for HRB215)
The mulching plug contours the
mower deck for efficient
mulching when the mower is
equipped with the two-piece
mulching blade assembly
(paw 8).
You can quickly remove the
plug to install a grass bag or
side-discharge chute.
DISCHARGE GUARD
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.
MULCHING PLUG
BLADES AND ATTACHMENTS
Side-Discharge Chute
(optional for HRB215 and HRM215)
The chute directs grass clippings away from the operator and
spreads them over the lawn. The clippings will be larger than
mulched particles, and they may need to be removed by raking.
Side-discharge mowing should be considered for less frequently
mowed areas where grass has grown too tall to mulch easily.
To attach the chute, lift the discharge guard, (remove the
mulching plug if so equipped), and hook the chute onto the
mower deck as shown. Release the discharge guard to secure
the chute.

BEFORE MOWING
This section explains how to fuel and check your mower to
be sure it is ready, and it tells you how to prepare your lawn
and yourself before you begin mowing.
For your safety and for the safety of others, always inspect the
area before mowing.
Objects
Anything which can be picked up by the blades 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.

BEFORE MOWING
Check Your Mower
BLADE(S)
/
Blade(s)
With the throttle lever in the
STOP position and the spark
plug cap disconnected, tilt the
mower to the right, so the
carburetor side is up. This will
help to prevent fuel leakage and
hard starting.
Inspect the blade(s) for wear
and damage.
NORMAL
EXCESSIVELY
WORN
Dull blades can be sharpened, but blades that are worn out, bent,
cracked, or otherwise damaged must be replaced. Worn or
damaged blades can break, causing blade pieces to be thrown
from the mower.
BLADE BOLTS
BENT
CRACKED
When the blade(s) needs sharpening or replacement take the
lawn mower to an authorized Honda lawn mower dealer. Or, if
you have a torque wrench, you can remove and install the
blade(s) yourself (see pages 58 - 59).
BLADE SHARPENING: To avoid weakening the blade(s), or
causing imbalance or poor cutting, the blade(s) should be
sharpened by trained staff at an authorized Honda lawn mower
dealer.
BLADE REPLACEMENT: Use genuine Honda replacement
blades or their equivalent.
Check that the blade bolts are tight. Use a wooden block to
prevent the blade(s) from turning when tightening the bolts. Wear
