Safety Instructions
All Operators Must Read These
Instructions Before Use
Always follow these safety guidelines. Failure to do so may
result in serious bodily injury or death.
General Safety WARNINGS!
When using electric lawn mowers, basic safety precautions
should always be followed to reduce the risk of re, electric
shock, and personal injury, including the following:
m WARNING: Risk of injury could occur if the lawn mower
is operated without the catcher assembly attached.
m WARNING: The use of any other accessory or
attachment might increase the risk of injury.
m WARNING: To reduce the risk of injury, inspect
catcher assembly frequently and replace with recommended
replacement if there are signs of wear or deterioration.
Before using the mower, take the time to familiarize yourself
with the controls, especially how to stop the mower in an
emergency. Only allow individuals who have a thorough
understanding of these instructions and operation of the
mower to use the mower. Never allow children to operate
the mower.
Retain this manual for future reference and reread it at the start
of each mowing season.
FOR DOUBLE-INSULATED LAWN MOWERS
1. Only use identical replacement parts when servicing
the mower.
2. Polarized Appliance Connections reduce the risk of
electric shock. This 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
mower’s plug will t into a polarized extension. 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 qualied
electrician to install the proper wall outlet. Do not
change the equipment plug, extension cord receptacle,
or extension cord plug in anyway.
m Contact with moving parts may cause entanglement,

dismemberment, or other serious bodily injury. Always
keep body parts (i.e.: hands, feet) at a distance 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 resulting
in serious injury. Keep the mower at a distance from
ammable or combustible items until surfaces that are
hot have completely cooled. Do not store mower near
ammable or combustible items.
A damaged blade or worn blade nut may break off the
mower assembly and cause serious injury. Replace the
damaged blade or blade nut before using the mower.
FOR ALL LAWN MOWERS
1. Avoid dangerous conditions. Do not use the mower in
the rain or when the grass is damp or wet.
2. Always keep children and spectators at a safe distance
from the mower during operation and as the machine
cools down.
3. Always wear personal safety gear (i.e.: glasses, rubber
gloves, protective footwear and dust mask) and proper
clothing when using the mower. Loose clothing, long
hair or jewelry may get caught in the moving parts.
4. Do not use lawn mower for any purpose except that for
which it is intended.
5. Ground fault circuit interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for
the lawn mower. Receptacles are available having
built-in GFCI protection and may be used for this
measure of safety.
6. To prevent electric shock use only with an extension
cord suitable for outdoor use, such as SW, SOW, STW,
STOW, SJTW, or SJTOW.
EXCEPTION: This warning does not apply to a battery
operated lawn mower.
7. Ensure the extension cord set is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. For lengths less than 100 feet, No. 14 AWG
extension cord should be used. An under sized cord
will cause a drop in line voltage resulting in loss of
power and overheating.
8. To reduce the likelihood of disconnection of lawn
mower cord set during operation:
i) Make a knot as shown in Figure 1, or
ii) Use one of the plug-receptacle retaining straps or
connectors described in this manual. Know Your
Lawn Mower.

m WARNING: Do not mow a slope that has an angle of
greater than 15° (a rise of approximately 2-1/2 ft. [ 75 m] every
10 ft. [3m]). Mow a cross the face of a slope, and never up
and down.
• When cutting thick grass, reduce walking speed in order to
allow for a more effective cut and a proper discharge of the
clippings. For a healthy lawn, always cut off one-third or less
of the total length of the grass. The average lawn should be
approximately 1-1/2 to 2 in. (3.8 to 5 cm) long during cool
month, and more than 2 in. (5cm) long during hot months. If
there is growth, the lawn should be cut in the fall.
Mulching Tips
NOTE: INSPECT THE AREA WHERE THE MOWER IS TO
BE USED AND REMOVE ALL THE STONES, STICKS, WIRES
AND OTHER DEBRIS THAT MIGHT BE THROWN BY THE
ROTATING BLADE.
1. Release the switch to turn the mower off when crossing
any graveled area (stone can be thrown by the blade).
2. Set mower to the highest cutting height when mowing
on uneven ground or in tall weeds.
3. For effective mulching, do not cut wet grass, because it
tends to stick to the underside of the deck, preventing
proper mulching of grass clippings. New or thick grass
may require a narrower cut. The ground speed should
be adjusted to the condition of the lawn. If mowing has
been delayed and the grass has been allowed to grow
longer than 4 in. (10 cm), mow the lawn twice in order
to reduce the grass to the maximum of 3 -1/4 in. (8.3
cm).
4. Walk at a steady pace. Overlap the cutting rows. Do
not let the grass get too tall. If the grass gets too long,
start at the highest cutting position and work down to
the desired cutting height.
m WARNING: If you strike a foreign object, stop the
motor and disconnect the power cord. Thoroughly inspect the
mower for any damage. Repair any damage before operating
the mower.
Cutting Blade Replacement
(Fig. 9 & Fig. 10)
Mowing Tips
NOTE: A sharp blade will greatly enhance the performance
of the mower, especially when cutting high grass.
Be sure to check the blade and to sharpen it at least once per
year, as described in the Maintenance section
• Verify that the lawn is free of stone, sticks, wires and other
objects that could damage the blades or the motor.
These objects could be accidentally thrown by the mower in
any direction, and could cause serious personal injury to the
operator and to others.
• In order to prevent electric shock, do not operate the
mower in damp or wet conditions.
• Do not mow in circle. Travel back and forth across the lawn.
m WARNING: Always protect your hands by wearing
heavy gloves and/or wrapping the cutting edges with rags
or other materials when performing any maintenance on the
blades.
1. Release the switch lever to turn the mower OFF, wait
for the blade to come to a complete stop.
2. While wearing leather padded gloves, wedge a block
of wood between the blade and the mower deck in
order to prevent the blade from turning when the nut is
being removed.
3. Using a 15-mm wrench or socket, loosen the blade
nut (1) “COUNTERCLOCKWISE” to loosen it and
“CLOCKWISE” to tighten it.
4. Remove the blade nut (1), the square washer (2), and
the blade (3).

Clean the Mower
m WARNING: To reduce the risk of electric shock, do not
expose the mower to water.
The underside of mower deck should be cleaned after each
use as grass clippings, leaves, dirt and other debris will
accumulate causing rust and corrosion.
Remove any buildup of grass and leaves on or around the
motor cover (do not use water). Wipe the mower clean with a
dry cloth occasionally.
• If debris build up on the underside of the unit while using,
stop the motor and disconnect it from the power supply.
Tilt the mower forward, or on its side, and scrape it clean
with an appropriate tool.
Storage
The following steps should be taken to prepare the lawn
mower for storage.
• Make certain the power is disconnected.
• Clean mower as instructed in previous section.
• Inspect and replace/sharpen blade, if required. Refer to
the Maintenance section.
• Store mower in a dry, clean area. Do not store next to
corrosive materials, such as fertilizer and rock salt.
• Wipe extension cord to remove any foreign substances
such as oil or stains. Replace extension cord if cut or
damaged in any way.
• Wind the cord in a series of equal loops to prevent it
from tangling.
• Store mower indoors, in a cool, dry place, out of reach
of children. Do not cover lawn mower with a solid plastic
sheet. Plastic coverings trap moisture around the mower
causing corrosion.
• The handle may be folded away completely for storage.
• Loosen the handle knobs on the sides of the handle, and
fold the upper handle down.
• Loosen the handle knobs, pull outwards on each side of
the lower handle, and lift the sides of the lower handle past
