Electrical Safety
1. Ground fault circuit interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for
the unit. Receptacles are available having built-in GFCI
protection and may be used for this measure
of safety.
2. Make sure that the mains voltage matches that listed on
the unit's rating label. Using the improper voltage can
damage the motor and injure the user.
3. 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-, CSA- or
ETL-listed extension cord recommended for outdoor,
all-weather use, such as the Snow Joe®+ Sun Joe®
Power Joe SJTW-A 14-gauge 50-foot extension cord
with lighted end (Model PJEXT50-B). Visit sunjoe.com to
purchase this extension cord online or, to order by phone,
call 1-866-SNOWJOE (1-866-766-9563).
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.
4. To prevent electric shock, use only with an extension cord
suitable for outdoor use, such as SW-A, SOW-A, STW-A,
STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A.
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. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
5. To prevent the appliance cord from disconnecting from the
extension cord during operation, make a knot with the two
cords as shown in Table 1.
6. Do not abuse the cord. Never pull the electric lawn mower
+ mulcher by the cord or yank the cord to disconnect it
from the receptacle. Keep the cord away from heat, oil,
and sharp edges.

mWARNING! Before performing any maintenance or
cleaning work, always disconnect the power supply
to the unit.
Mowing Tips
mWARNING! Inspect the area prior to mowing/mulching
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 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, as described in the
maintenance section.
• Verify that the lawn is free of stone, sticks, wires, and other
foreign objects that could damage the blade or the motor.
These objects could accidentally be picked up and thrown
by the mower in any direction, which could lead to 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 a circle. Travel back and forth across the
lawn following the path outlined below (Fig. 11).
• 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.
• 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 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 disconnect the power cord. Thoroughly inspect the mower
for any damage. Repair any damage before operating the
mower.
Mulching Tips
mWARNING! Inspect the area prior to mowing/mulching
and remove all the stones, sticks, wires, and other debris that
might be thrown by the rotating blade.
• The unit is sent in mulching mower mode with the mulch
plug being assembled already. If you have used the unit
as a lawn mower and want to convert your lawn mower to
a mulching mower, lift up the grass collection bag cover
and remove the grass collection bag. Insert the mulch plug
(Fig. 12) and close the grass collection bag cover.
• For eective 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 3¼ in. (8.3 cm).
• 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.

mWARNING! 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.
Maintenance
mWARNING! Before cleaning, repairing, or inspecting the
electric lawn mower + mulcher, disconnect the power supply
to the unit and verify that all moving parts have come to a
complete stop.
1. Do not spray the unit with water. Intake of water may
destroy the switch/plug mechanism and the electric
motor.
2. Clean the unit with a dry cloth or hand brush. Expert
inspection is required:
a) if the lawn mower + mulcher strikes an object.
b) if the motor stops suddenly.

d) if the motor shaft is bent (do not align).
e) if a short-circuit occurs when the cable is connected.
f) if the gears are damaged.
g) if the V-belt is defective.
Replacing and Resharpening the
Mowing Blade
At the end of each mowing season, always resharpen the
mowing blade or, if required, replace the mowing blade
with a new one. You can purchase a replacement blade
(Model MJ403E-32) and other replacement parts online at
sunjoe.com. Always have the mowing blade resharpened or
replaced by an authorized Snow Joe®+ Sun Joe®service
center.
1. Disconnect the electrical supply to the mower.
2. Turn the mower on its side to expose the underside of the
blade housing.
3. Use a cloth to grip the blade or wear heavy-duty gloves.
4. Using an adjustable wrench, remove the bolt securing the
mower blade by turning the bolt counterclockwise, then
carefully remove the blade (Fig. 13).
5. Fit the new blade and the bolt back on following the same
steps in reverse order.
mWARNING! Unbalanced blades will cause the electric
lawn mower + mulcher to vibrate violently and may cause an
accident. Please follow proper maintenance procedures or
call the Snow Joe®+ Sun Joe®customer service center for
assistance at 1-866-SNOWJOE (1-866-766-9563).
Storage
Follow the steps below to prepare the electric lawn mower +

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

verify that they are in proper working order.
8. After striking a foreign object, stop the motor and remove
the power cord. Thoroughly inspect the mower for any
damage. Repair any damage before restarting the mower.

picked up and thrown by the machine. As a safety
precaution, frequently check the mower's components
and replace those that show signs of wear or damage.

and clean area, out of the reach of children.
