WARNING:
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below and on the machine
may result in electric shock, fire, and/or serious personal injury.
Stop the motor, wait until the blade comes to a complete stop, and
disconnect from power supply before cleaning the lawn mower,
removing the grass catcher, or removing the mulching plug. Never
use a hose, water, or any liquids to clean the lawn mower, as water
can damage electronic components. Remove any buildup of grass
and leaves on or around the motor cover. Wipe the mower clean with
a dry cloth occasionally.
Replace blade if it is bent or cracked. An unbalanced blade causes
vibration that could damage the motor drive unit or cause personal
injury. Sharpen a dull blade equally at each end to maintain the
balance. Clean the blade thoroughly and check its balance by
supporting it horizontally on a thin nail through its center hole. The
nail should be in a horizontal position. If either end of the blade
rotates downward, remove some metal from the heavy or lower end
until the blade is balanced. It is balanced when neither end drops.
When not in use, mower should be stored indoors in a dry, locked up
place—out of reach of children. The extension cord should also be
removed and stored in a separate location out of the reach of
children.
Always use safety protective devices. Do not operate the mower
without the entire grass catcher discharge guard, rear guard, or other
safety protective devices in place and working properly.
Follow manufacturer’s instructions for proper operation and
installation of accessories. Only use accessories approved by the
manufacturer.
To reduce the risk of electric shock, this appliance has a polarized
plug (one blade is wider than the other) and will require the use of a
polarized extension cord. The appliance plug will fit into a polarized
extension cord only one way. If the plug does not fit 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 fit fully into the
wall outlet, reverse the plug. If the plug still does not fit, contact a
qualified electrician to install the proper wall outlet. Do not change the
equipment plug, extension cord receptacle, or extension cord plug in
any way.
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.
Inspect lawn mower cord periodically and if damaged, have it
repaired by an authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean, and
free from oil and grease.
Warning — To prevent electric shock use only with an extension cord
suitable for outdoor use, such as SW, SOW, STW, STOW, SJW,
SJOW, SJTW, or SJTOW.
Extension Cord - Make sure your 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 50 feet, No. 14 AWG extension cord should be used. An
undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. To reduce the likelihood of disconnection of
lawn mower cord from the cord set during operating use the cord
retainer described in this manual.
Under normal usage the catcher assembly is subject to deterioration
and wear and should, therefore, be frequently checked for
replacement. Only use identical replacement catcher assemblies.
Don’t Abuse Cord — Never pull lawn mower by cord or yank it to
disconnect from receptacle. Keep cord from heat, oil, and sharp
edges.
Risk of death or serious personal injury if power lines or electric cords
are contacted. Never operate mower over electrical sources, cords,
or wires.
Clear the work area before each use. Remove all objects such as
rocks, tree nuts, sticks, metal, wire, bones, toys, or other objects
which can be thrown by the blade. Stay behind the handle when the
motor is running.
This lawn mower is capable of amputating hands and feet and
throwing objects. Failure to observe all safety instructions could
result in serious injury or death.
Avoid Dangerous Environment - Do not use the lawn mower in
damp or wet conditions or operate in the rain.
Only allow responsible adults, who are familiar with the
instructions, to operate this machine.
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 lawn mower.
Use extra care when approaching blind corners, shrubs,
trees, or other objects that may block your view of a child.
Dress properly - Do not wear loose clothing or jewelry. They can
be caught in moving parts. Use of rubber gloves and footwear is
recommended when working outdoors.
Don’t over reach - Keep firm footing and balance. Do not
overreach. Over-reaching can result in loss of balance.
Do not operate the equipment with 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 artificial light.
Use safety glasses - Always wear safety glasses with side
shields. 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 environment 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 influence of drugs, alcohol, or
medication. A moment of inattention while operating the lawn
mower may result in serious personal injury.

GENERAL SAFETY
DOUBLE INSULATION – The mower has double insulation. This
means that all external metal parts are insulated from the electrical
supply. This is achieved by introducing an insulation layer between
electrical and mechanical parts. The double insulation guarantees
you the greatest possible safety.
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) protection
should be provided on the circuit or outlet to be used for the
mower. Receptacles are available having built-in GFCI protection
and may be used.
EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord be sure it is heavy
enough to carry the current your product will draw. An undersized
extension cord will cause a drop in line voltage resulting in loss of
power and overheating. The following table shows the correct size
to use depending on cord length and nameplate ampere rating. If
in doubt, use the next heavier gage. The smaller the gage number,
the heavier the cord.
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.
WARNING:
The double insulated system is intended to protect the user from
shock resulting from a break in the tool’s internal insulation.
Observe all normal safety precautions to avoid electrical shock.
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, 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.
WARNING:
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 product with a damaged cord since touching
the damaged area could cause electrical shock resulting in serious
injury.

other obj
ects that could damage the lawn mower
blades or motor. Such objects could be acciden
tally
thrown by the mower in any direc
tion and cause
serious personal injury to the operator a
nd others.
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 m
ore effective cutting and a proper discharge
of the clipping
s.

SHARPENING THE BLADE
See Figure 15
For best mowing performance, the mower blade must be
kept sharp. A dull blade does not cut grass evenly and
overloads the motor. Under normal circumstances,
sharpening the blade twice during the mowing season is
usually sufficient. However, if your lawn has sandy soil,
more frequent sharpening's may be required.
Following the instructions in the Replacing the
Cutting Blade section, remove the mower blade. DO
NOT attempt to sharpen the blade while it is attached
to the mower.
Using a fine tooth file or stone, sharpen cutting edges
on both ends of the blade, removing equal amounts of
material from both ends.
BALANCING THE BLADE
See Figure 16
When sharpening, care should be taken to keep the blade
balanced. An unbalanced blade will cause excessive
vibration when the mower is running. This vibration will
eventually cause damage
to the mower, especially
the motor.
To check blade balance:
Clamp a screwdriver
horizontally in a vise as
shown.
NOTE: If a vise is not
available, a straight nail
can also be used.
WARNING:
When removing, inspect the blade carefully. If blade is
bent or damaged, replace immediately with a new blade.
Failure to replace a bent or damaged blade could cause
an accident resulting in possible serious injury.
MAINTENANCE
Place the center hole of blade on the screwdriver
(or nail) shank.
If blade is balanced, it will remain in a horizontal
position. If either end of the blade drops downward,
sharpen the heavy side until the blade is balanced.
