General Safety WARNINGS!

should always be followed to reduce the risk of re, electric
shock, and personal injury. These precautions include:
mWARNING! Do not operate without the entire grass
collection bag or other safety protective devices in place and
in proper working order.
mWARNING! The use of any other accessory or
attachment might increase the risk of injury.
mWARNING! To reduce the risk of injury, inspect the
grass collection bag frequently and replace with recommended
replacement if there are signs of wear or deterioration.
Before using the lawn mower, take the time to familiarize
yourself with the controls, especially how to stop the lawn
mower in an emergency. The only individuals who should use
the lawn mower are those who have a thorough understanding

FOR DOUBLE-INSULATED
LAWN MOWERS
1. Replacement parts – When servicing this unit, use only
identical replacement parts. Replace or repair damaged
cords immediately.
2. Polarized plug – Polarized appliance connections reduce
the risk of electric shock. This lawn mower has a polarized
plug (one blade is wider than the other) and will require the
use of a polarized extension cord. There is only one way
the lawn mower’s plug will t into a polarized extension
cord. If the plug does not t fully into the extension cord,
reverse the plug. If the plug still does not t, obtain a
correct polarized extension cord. A polarized extension
cord will require the use of a polarized wall outlet. There
is only one way the plug will t into a polarized wall outlet.
If the plug does not t fully into the wall outlet, reverse
the plug. If the plug still does not t, contact a qualied
electrician to install the proper wall outlet. Do not change
the equipment plug, extension cord receptacle, or
extension cord plug in any way.
mWARNING! Contact with moving parts may cause
entanglement, dismemberment, or other serious bodily
injury. Always keep body parts (i.e. hands, feet) a safe
distance away from moving parts. Ensure all covers and
guards are securely in place before use.
Hot surfaces (i.e. the motor) may ignite ammable or
combustible items and cause a re or explosion, which can
result in serious bodily injury. Keep the lawn mower a safe
distance away from ammable or combustible items until
surfaces that are hot have completely cooled. Do not store
the lawn mower near ammable or combustible items.
A damaged blade or worn blade nut may break o the lawn
mower assembly and cause serious injury. Replace the
damaged blade or blade nut before using the lawn mower.
FOR ALL LAWN MOWERS
1. Avoid dangerous conditions – Do not use the lawn
mower in the rain or when the grass is damp or wet.
2. Keep children, bystanders, and pets away – Always keep
children and spectators a safe distance away from the lawn
mower during operation and as the machine cools.
3. Dress properly – Always wear personal safety gear
(i.e. glasses, rubber gloves, protective footwear, and dust
masks) and proper clothing when using the lawn mower.
Loose clothing, long hair, or jewelry may get caught in
the moving parts. Wear a protective covering to contain
long hair.
4. Use the right appliance – Do not use the lawn mower for
any applications other than those for which it was intended.
5. Do not force the lawn mower – It will perform better with
less likelihood of personal or mechanical injury if it is used
at the rate for which it was designed.
6. Do not overreach – Keep proper footing and balance at
all times.
7. Stay alert – Always stay alert and watch what you are
doing. Use common sense. Do not operate the lawn
mower when you are tired or under the inuence of
alcohol or drugs. This lawn mower is not designed to be
