INSTRUCTIONS.Failure to follow all instructions
listed below and on the machine may result in electric
shock, re, and/or serious personal injury.
WARNING!
READ ALL INSTRUCTIONS
■ This cutting machine is capable of amputating hands
and feet and throwing objects. Failure to observe all
safety instructions could result in serious injury or death.
■ Do not operate power tools in explosive
atmospheres, such as in the presence of ammable
liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
■ Avoid body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is grounded.
■ Do not use the lawn mower in damp or wet
conditions or operate in the rain.
■ Never allow adults to operate the product without
proper instruction.
■ Keep the area clear of all bystanders, children, and pets
while mowing. Stop machine if anyone enters the area.
■ Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often attracted
to the machine and the mowing activity. Never assume
that children will remain where you last saw them.
• Keep children out of the mowing area and under
the watchful care of a responsible adult other than
the operator.
• Be alert and turn mower off if a child enters the
area.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may block your
view of a child.
■ Do not wear loose clothing or jewelry. They can be
caught in moving parts.
■ Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance.
■ Do not operate the equipment while barefoot or
when wearing sandals or similar lightweight footwear.
Wear protective footwear that will protect your feet and
improve your footing on slippery surfaces.
■ Do not leave the mower unattended while running.
■ Keep hands and feet away from cutting area. Keep
clear of the discharge opening at all times.
■ Operate the lawn mower only in daylight or good
articial light.
■ Always wear safety glasses with side shields marked
to comply with ANSI Z87.1. Everyday glasses have only
impact resistant lenses. They are NOT safety glasses.
Following this rule will reduce the risk of eye injury. Use
face mask if operation is dusty.
■ Wear safety glasses or goggles that are marked to comply
with ANSI Z87.1 standard when operating this product.
■ Use the right appliance. Do not use the lawn mower
for any job except that for which it is intended.
■ Do not force the lawn mower. It will do the job better
and safer at the rate for which it was designed.
■ Stay alert, watch what you are doing, and use
common sense when operating the lawn mower.
Do not operate the mower while tired or under the
inuence of drugs, alcohol, or medication. A moment
of inattention while operating the lawn mower may
result in serious personal injury.
■ Keep machine in good working condition. Keep
blades sharp and guards in place and in working order.
■ Check all nuts, bolts, and screws at frequent
intervals for proper tightness to be sure the equipment
is in safe working condition.
■ Stop the motor and wait until the blade comes to a
complete stop and remove power cord before cleaning
the lawn mower, removing the grass catcher, or
unclogging the discharge guard.
■ When not in use, the mower should be stored
indoors in a dry, locked up place—out of the reach of
children.
■ To reduce the risk of electric shock, this product has
a polarized plug (one blade is wider than the other)
and will require the use of a polarized extension cord.
The plug will fit into a polarized extension cord only
one way. If the plug does not t fully into the extension
cord, reverse the plug. If the plug still does not fit,
obtain a correct polarized extension cord. A polarized
extension cord will require the use of a polarized wall
outlet. This plug will fit into the polarized wall outlet
only one way. If the plug does not t fully into the wall
outlet, reverse the plug. If the plug still does not fit,
contact a qualied electrician to install the proper wall
outlet. Do not change the equipment plug, extension
cord receptacle, or extension cord plug in any way.
■ Do not abuse the cord. Never use the cord to pull
the lawn mower or to disconnect the plug from an
outlet. Keep cord away from heat, oil, sharp edges, or
moving parts. Replace damaged cords immediately.
Damaged cords increase the risk of electric shock.
■ Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gauge size (A.W.G.) of at least 14 is
3 — English
recommended for an extension cord 50 feet or less
in length. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
■ WARNING: Use outdoor extension cords marked
SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or
SJTOWA. These cords are rated for outdoor use and
reduce the risk of electric shock.
■ 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 builtin GFCI protection and may be used for
this measure of safety.
■ Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil
or grease.

ELECTRICAL
8 — English
DOUBLE INSULATION
See Figure 2.
Double insulation is a concept in safety in electric
power tools, which eliminates the need for the usual
threewire grounded power cord. All exposed metal
parts are isolated from the internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.
NOTE: Servicing of a product with double insulation
requires extreme care and knowledge of the system
and should be performed only by a qualied service
technician. Always use original replacement parts as
listed in the Parts List pages of this manual.
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It
should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current).
Do not operate this product on direct current (DC).
A substantial voltage drop will cause a loss of power
and the motor will overheat. If the product does not
operate when plugged into an outlet, double-check
the power supply.
EXTENSION CORDS
See Figure 2.
When using a power tool at a considerable distance
from a power source, be sure to use an extension
cord that has the capacity to handle the current the
product will draw. An undersized cord will cause a
drop in line voltage, resulting in overheating and loss
of power. Use the chart to determine the minimum
wire size required in an extension cord. Only round
jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a product, use an
extension cord that is designed for outside use. This
type of cord is designated with “WA” on the cord’s
jacket.
Before using any extension cord, inspect it for loose
or exposed wires and cut or worn insulation.
It is possible to tie the extension cord and power
cord in a knot to prevent them from becoming
disconnected during use. Make the knot as shown in
gure 2, then connect the plug end of the power cord
into the receptacle end of the extension cord. This
method can also be used to tie two extension cords
together.
READ AND UNDERSTAND ALL
INSTRUCTIONS. Failure to follow all instructions listed
below and on the machine may result in electric shock,
re, and/or serious personal injury.
Keep the extension cord clear of
the working area. Position the cord so that it will not
get caught on lumber, tools, or other obstructions while
you are working with a power tool. Failure to do so can
result in serious personal injury.
Check extension cords before
each use. If damaged replace immediately. Never use
the product with a damaged cord since touching the
damaged area could cause electrical shock resulting in
serious injury.
Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints
• crystalline silica from bricks and cement and
other masonry products
• arsenic and chromium from chemically-treated
lumber
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a
well ventilated area, and work with approved
safety equipment, such as those dust masks that
are specially designed to filter out microscopic
particles.

APPLICATIONS
You may use this product for the purpose listed
below:
■ Mowing your lawn
STARTING/STOPPING THE MOWER
See Figure 8.
■Attach the outlet end of an extension cord to the
plug on the rear of the mower.
NOTE: Use only an approved outdoor extension cord
as described previously in this manual.
■ Press and hold the start button. Pull the bail switch
towards the handle and release the button to release
the mower.
■ To stop the mower, release the bail switch.
NOTE: A high-pitched noise and sparking may occur
as the electric motor decelerates. This is normal.
MOWING TIPS
See Figure 9 - 10.
■ Make sure the lawn is clear of stones, sticks, wires,
and other objects that could damage the lawn mower
blades or motor. Such objects could be accidentally
thrown by the mower in any direction and cause
serious personal injury to the operator and others.
■ To reduce the likelihood of disconnecting the lawn
mower from the extension cord, be sure to use the
cord retainer provided.
■ Do not mow in circles. Start from the point closest to
the outlet and travel back and forth across the lawn,
moving away from the outlet so the cord remains
behind the mower in the cut portion of the lawn.
■ Do not allow the extension cord to wrap around
trees, shrubs, or other obstacles. When picking up
the extension cord, wind the cord in a series of equal
loops to prevent it from tangling.
■ For a healthy lawn, always cut off one-third or less
of the total length of the grass.
■ When cutting heavy grass, reduce walking speed
to allow for more effective cutting and a proper
discharge of the clippings.
■ Do not cut wet grass. It will stick to the underside
of the deck and prevent proper mulching of grass
clippings.
■ New or thick grass may require a narrower cut.
■ Clean the underside of the mower deck after each
use to remove grass clippings, leaves, dirt, and any
other accumulated debris.
SLOPE OPERATION
See Slope Gauge on page vi.
■ Slopes are a major factor related to slip and fall
accidents that can result in severe injury. Operation
on slopes requires extra caution. If you feel uneasy
on a slope, do not mow it. For your safety, do not
attempt to mow slopes greater than 15 degrees.
■ Mow across the face of slopes, not up and down.
Exercise extreme caution when changing direction on
slopes.
■ Watch for holes, ruts, rocks, hidden objects, or
bumps which can cause you to slip or trip. Tall grass
can hide obstacles. Remove all objects such as
rocks, tree limbs, etc., which could be tripped over or
thrown by the blade.
■ Always be sure of your footing. A slip and fall can
cause serious personal injury. If you feel you are
losing your balance, release the switch control lever
immediately.
■ Do not mow near drop-offs, ditches, or
embankments; you could lose your footing or balance.
Do not allow familiarity with this
type of product to make you careless. Remember that
a careless fraction of a second is sufcient to inict
serious injury.
Always wear safety goggles or
safety glasses with side shields when operating this
product. Failure to do so could result in objects being
thrown into your eyes, resulting in possible serious
injury.
Do not use any attachments or
accessories not recommended by the manufacturer of
this product. The use of attachments or accessories
not recommended can result in serious personal
injury.
