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 this cordless lawn mower, basic safety
precautions 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
catcher, discharge guard, rear guard 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
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. The only individuals who should use the
mower are those who have a thorough understanding of the
instructions and who know how to operate the machine.
Children should never be allowed access to the mower.
Retain this manual for future reference and reread it at the start
of each mowing season.
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 mower a safe
distance away from ammable or combustible items until
surfaces that are hot have completely cooled. Do not store
the 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.
1. Avoid dangerous conditions – Do not use the 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 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 mower.
Loose clothing, long hair or jewelry may get caught in the
moving parts.
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 – Turn OFF and remove
safety key when the mower is not in use, before servicing
it, 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.
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 insert the safety key, 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.

Mowing Tips
mWARNING! Inspect the area prior to mowing and
remove all the stones, sticks, wires and other foreign objects
that could be picked up and thrown by the rotating blade.
Failure to comply not only will damage the mower blade,
but can also lead to serious personal injury.
• Be sure to check the mowing blade periodically for signs
of wear and sharpen it at least once per year, as described
in the maintenance section.
NOTE: A sharp blade will greatly enhance the
performance of the mower, especially when cutting tall
blades of grass.
• 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 in. 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.
• The lawn will look better if it is always cut to the same
height and in alternate directions.
• When crossing any gravelled surfaces, release the switch
bar lever to turn o the mower. The stones can be picked
up and thrown by the rotating blade.
• Set the 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 remove the safety key. Thoroughly inspect the mower and
repair any damage before resuming work.
• IMPORTANT! Never open the ejector ap when the grass
collection bag has been detached (to be emptied) and the
motor is still running. A rotating blade can cause serious
injuries!
• Always carefully fasten the ejector ap and grass
collection bag. Switch o the motor before emptying the
grass collection bag. Always ensure that a safe distance
(provided by the length of the long handles) is maintained
between the user and the mower housing. Be especially
careful when mowing and changing direction on slopes
and inclines.
• Maintain a solid footing and wear sturdy, non-slip footwear
and long trousers. Always mow across an incline
(not up and down).
• For safety reasons, the lawn mower may not be used to
mow inclines with gradients exceeding 15 degrees.
• Use special caution when backing up and pulling the lawn
mower towards you as such maneuvering of the machine
poses a tripping hazard.
Maintenance + Care
mWARNING! Before cleaning, repairing or inspecting
the mower, disconnect the power supply by plugging out the
safety key and verify that all moving parts have come to a
complete stop.
General
• Always keep the 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 assembly 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 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:

sunjoe.com or calling our toll-free customer service helpline
at 1-866-SNOWJOE (1-866-766-9563). The use of parts that

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

Storage
Follow the steps below to prepare the lawn mower for storage:
1. Remove the safety key from the slot.
2. Clean the mower with a damp cloth or hand brush.
3. Inspect the 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
