of each mowing season.

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 be 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.

8. Disconnect the lawn mower – Disconnect the lawn
mower from the power supply when it is not in use,
before servicing, when changing accessories, and when
performing any other maintenance task.

9. Store idle lawn mower indoors – When not in use, the
lawn mower should be stored indoors in a dry, locked
place out of the reach of children.

10. Maintain the lawn mower with care – Keep cutting
edges sharp and clean for best and safest performance.

Inspect the lawn mower cord periodically and if damage

is found have it repaired by an authorized service facility.
Extension cords should also be inspected periodically
and immediately replaced if damaged. Keep handles dry,
clean, and free from oil and grease.

11. Use personal protective equipment. Always wear eye
protection – Protective equipment such as safety glasses,

a dusk mask, non-skid safety shoes, a hard hat, and
hearing protection, when used for appropriate conditions,
will reduce the possibility of personal injuries.

12. Avoid unintentional starting – Ensure the switch is in the
OFF position before connecting the power cord, or before
picking up or carrying the tool. Carrying power tools with

your nger on the switch or charging power tools with the

switch ON can lead to accidents.

13. Remove any adjusting key or wrench before starting
the power tool – A wrench or a key left attached to a

rotating part of the power tool may result in personal
injury.

14. Keep cutting blades sharp and clean – Properly
maintained cutting blades with sharp edges are less likely
to bind and are easier to control.

15. Keep all parts of the body away from the cutting blade
– Do not remove cut material or hold material to be cut

when blade is moving. Make sure the switch is o when

clearing jammed material. A moment of inattention while
operating the product may result in serious personal injury.

16. If the lawn mower strikes a foreign object, follow these
steps:

i) Stop the lawn mower by releasing the On/O switch

lever.

ii) Disconnect the power cord.

iii) Inspect for damage.

iv) Repair any damage before restarting and operating

the lawn mower.

17. Only use identical replacement blades and
other genuine parts.

18. Keep guards in place and in proper working order.

Electrical Safety

1. 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.

2. To reduce the risk of electric shock, this appliance has
a polarized plug (i.e. one blade is wider than the other).
Use this appliance only with a polarized, UL-listed (CSA

certied in Canada) extension cord recommended for
outdoor use. The appliance plug will t into a polarized

extension cord only one way.

If the appliance 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. The

extension cord plug will t 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 t,
contact a qualied electrician to install the proper wall

outlet. Do not modify the appliance plug, extension cord
receptacle, or extension cord plug in any way.

3. To prevent electric shock, use only with an extension cord
suitable for outdoor use, such as SW, SOW, STW, STOW,
SJTW, or SJTOW.

Before use, check that the extension cord is in good

condition. When using an extension cord, make sure to
use one heavy enough to carry the current your product
will draw. For lengths less than 50 feet, a 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.

m WARNING m

Electric shock may cause SEVERE INJURY or
DEATH. Heed these warnings:

• Do not allow any part of the lawn mower to make

contact with water while it is in operation. If the

appliance becomes wet while turned o, wipe dry

before starting.

• Use only a UL-, CSA-, or ETL-rated extension cord for

outdoor, all-weather use, such as the Snow Joe
Sun Joe
with lighted end (Model PJEXT50-B). Visit snowjoe.
com to purchase this extension cord online or, to order
by phone, call 1-866-SNOWJOE (1-866-766-9563).

• Do not use an extension cord over 100 ft (30 m).

• Do not touch the appliance or its plug with wet hands

or while standing in water. Wearing rubber boots

oers some protection.

Double-Insulated Appliances

In a double-insulated appliance, two systems of insulation
are provided instead of grounding. No grounding means are
provided on a double-insulated appliance, nor should a means
for grounding be added to the appliance. Servicing a double­insulated appliance requires extreme care and knowledge

of the system, and should be performed only by qualied

service personnel at an authorized Snow Joe® + Sun Joe®
dealer. Replacement parts for a double-insulated appliance
must be identical to the parts they replace. A double-insulated
appliance is marked with the words “Double Insulation” or
“Double Insulated.” The symbol (square within a square)
may also be marked on the appliance.

DOUBLE-INSULATED: GROUNDING NOT

REQUIRED. WHEN SERVICING, USE ONLY
IDENTICAL REPLACEMENT PARTS.

This electric lawn mower is double-insulated, eliminating the
need for a separate grounding system. Use only identical
replacement parts. Read the instructions before servicing
double-insulated appliances. Use this lawn mower only as
described in this manual.

Mowing Tips

mWARNING! Inspect the area prior to mowing and

remove all the stones, sticks, wires, and other debris that
might be thrown by the rotating blade.

NOTE: A sharp blade will greatly enhance the performance of
the lawn mower, especially when cutting tall blades of grass.

• Be sure to check the blade periodically for signs of wear

and sharpen it at least once per year.

• In order to prevent electric shock, do not operate the lawn
mower in damp or wet conditions.

• Do not mow in a circle. Travel back and forth across the

lawn following the path outlined below (Fig. 14).

• When cutting thick grass, reduce your walking speed
in order to allow for a more eective cut and a proper

discharge of the clippings. For a healthy lawn, always

cut o one-third or less from the total length of the grass.

The average lawn should be approximately 1.5 to 2 in.
(3.8 cm to 5 cm) long during cool months, and more than
2 in. (5 cm) long during hot months. If there is growth,
the lawn should be cut in the fall.

10

Fig. 14

• While mowing, make sure that the electric cable is always

behind you and resting on the area of grass already cut.

• The lawn will look better if it is always cut to the same

height and in alternate directions.

• When crossing any graveled area, release the On/O
switch lever to turn o the lawn mower. The stones can be

picked up and thrown by the rotating blade.

• Set the lawn mower to the highest cutting height when

mowing on uneven ground or in tall weeds.

mWARNING! If you strike a foreign object, stop the motor

and disconnect the power cord. Thoroughly inspect the lawn
mower for any damage. Repair any damage before operating
the lawn mower.

Overload Protection

The lawn mower has an internal cut o switch which will stop

the operation of the motor temporarily if overloaded. This cut

o switch will suddenly stop the motor from operating should

the motor become too hot during the operation of the lawn
mower.

1. Disconnect the lawn mower from the power supply and
inspect blade for any obstructions.

2. Wait up to 2 minutes, or longer depending on ambient
temperature and the operation being performed, before
switching on the lawn mower and resuming normal
operation.

mWARNING! The mower blade will continue to rotate for

a brief period after the unit has been switched o. Do not tilt or

carry the unit while the motor is still running and do not touch
the blade while it is still rotating. Failure to comply could result
in severe personal injury.

Maintenance

mWARNING! Before cleaning, repairing, or inspecting the

lawn mower, disconnect the power supply to the unit and verify
that all moving parts have come to a complete stop.

General

• Always keep the lawn mower clean and free of grass, dirt,

or other debris.

• Keep the handles dry, clean, and free of oil and grease.

• After each cutting session, remove accumulated grass

clippings and debris using either a dry cloth or handbrush.
You may also clean the equipment with a damp cloth and
some soft, non-abrasive soap. Do not use cleaning agents
or harsh solvents as they may damage the equipment's
plastic components. Make sure that no water penetrates
the equipment's interior as intake of water can destroy the
switch/plug mechanism and the electric motor.

• Do not clean the lawn mower with running water,

particularly with high-pressure water.

• Check all nuts, bolts, and screws for proper tightness

before each use.

• Frequently inspect the grass collection bag for signs of

wear and replace immediately with a genuine Snow Joe®
+ Sun Joe® part if damage is found.

• Replace excessively worn or damaged parts immediately.

• To maximize your lawn mower's longevity, all screwed

parts, including the wheels and axles, should be cleaned
and lubricated. There are no parts inside the equipment
which require additional maintenance or lubrication.

Blade Maintenance

IMPORTANT: The mower blade is sharp and can cause severe

personal injury if handled incorrectly. Wrap the blade or wear
protective gloves, and use extra caution when handling.

The steel blade is designed to provide a ne cut in long or

tough grass. Deterioration in the quality of cut indicates blade
wear or damage. Follow these steps to determine if the blade
needs to be resharpened or replaced:

1. Disconnect the electrical supply to the lawn mower.

2. Turn the lawn mower on its side to expose the underside

of the blade housing.

Blade Replacement

IMPORTANT: Only use original replacement parts specied for

this lawn mower.

You can purchase a replacement blade (Model MJ404E-BLD)
and other genuine replacement parts by ordering online at
snowjoe.com or, to order by phone, contact Snow Joe® +
Sun Joe® customer service at 1-866-SNOWJOE
(1-866-766-9563). The use of parts that do not meet the

original equipment specications may lead to improper

performance of the lawn mower, may compromise operator
safety, and will void the manufacturer's warranty.

1. Disconnect the electrical supply to the lawn mower.

2. Turn the lawn mower on its side to expose the underside

of the blade housing.

3. Wear heavy-duty gloves, or use a cloth to grip the blade.

4. To remove the blade bolt, hold the blade rmly by one

hand, and use the supplied spanner wrench to loosen the
blade bolt by turning it counterclockwise (Fig. 15).

Storage

Follow the steps below to prepare the lawn mower for storage:

1. Disconnect the power supply to the lawn mower.

2. Clean the lawn mower with a damp cloth or hand brush.

3. Inspect the lawn mower carefully for worn, loose, or

damaged parts. Check connections and screws and
tighten if necessary. Pay special attention to the mower
blade and replace/sharpen if it shows signs of wear. Refer
to the Maintenance section.

4. Store the lawn mower indoors in a dry, clean, and cool
area out of the reach of children. Do not store the unit next
to corrosive materials, such as fertilizer and rock salt.

5. Wipe the extension cord to remove any foreign
substances, such as oil or stains. Replace the extension
cord immediately if it is cut or damaged in any way.

6. Wind the cord in a series of equal loops to prevent it
from tangling.

7. Do not cover the lawn mower with a solid plastic sheet.
Plastic coverings trap moisture around the lawn mower,
which can damage the unit.

compact storage or hanging. Follow the instruction below.

Storage Position

i) Loosen the lower handle knobs on both sides.

ii) Flip the handle assembly to the front until the second
