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

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

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 stay alert and watch what you are
doing. Use common sense. Do not operate the lawn

used by people (including children) with limited physical,
sensory or mental capacities. It should also not be used
by those lacking the proper experience and/or knowledge
unless they are supervised by a person who is responsible
for their safety or they have received instructions from
such a person on how to safely use the equipment.
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.
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

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.
4. 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.
5. Do not abuse the cord. Never pull the lawn mower by the
cord or yank the cord to disconnect it from the receptacle.
Keep the cord away from heat, oil, and sharp edges.

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 double-
insulated appliance requires extreme care and knowledge
VM[OLZ`Z[LTHUKZOV\SKILWLYMVYTLKVUS`I`X\HSPÄLK
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.

Operation
This lawn mower is intended for private residential use to cut
grass in small lawns and gardens. This lawn mower is not
PU[LUKLK[VJ\[NYHZZPUW\ISPJWHYRZWSH`PUNÄLSKZMHYTZVY
forests. Do not use this lawn mower for any application other
than that for which it is intended.
Adjusting the Cutting Height
This electric lawn mower is equipped with a 3-position height
adjustment system to tailor grass cutting heights of 0.98 inch,
1.77 inch, and 2.56 inch. To change the cutting height of the
grass, follow the instructions below.
mWARNING! Before making these adjustments,
disconnect the power supply to the lawn mower and wait until
the rotating blade has come to a complete standstill. Wearing
gloves is recommended due to the close proximity of the
cutting blade.
ALWAYS FOLLOW ALL SAFETY PRECAUTIONS AND
RECOMMENDATIONS LISTED PREVIOUSLY IN THIS
MANUAL.
1. Power VɈHUK\UWS\N[OLSH^UTV^LY
2. The height adjustment slots are behind each wheel. To
adjust the height, place the lawn mower on its side. Pull
the wheel lever out of the original slot, and insert it in
desired slot by moving the wheel on each side (Fig. 8).
3-Position Height Adjustment:
(1) 0.98 in. (25 mm)
(2) 1.77 in. (45 mm)
(3) 2.56 in. (65 mm)
3. Reconnect the power supply to the lawn mower and
resume normal use.
NOTE: Make sure to adjust the two wheel levers in the
same slot on each side to avoid an uneven cut.
Starting + Stopping
Do not switch on the lawn mower until it has been completely
assembled. Before switching on the unit, always check the
appliance cord and the extension cord for signs of damage.
Use only intact cords.
mWARNING! Damaged cords pose a severe risk of injury.
Replace damaged cords immediately.
mWARNING! Before switching on the lawn mower, make
sure that it is not in contact with any foreign objects. Keep
your hands and feet a safe distance away from the rotating
mower blade and the ejector opening. Failure to comply with
these warnings can result in severe personal injury.
IMPORTANT: Do not start the lawn mower in tall grass.
1. Place the unit on a level lawn surface.
2. Push a loop of the extension cord through the slot on the
extension cord restraint holder from the opposite side and
around the cord restraint hook. Insert the appliance cord
into the extension cord (Figs. 9 – 10).
NOTE: Do not plug the extension cord into the outlet until it
had been secured with the extension cord restraint holder and
connected to the lawn mower's appliance cord. Only use a
UL-rated extension cord for outdoor, all-weather use. Do not
use an extension cord over 100 ft (30 m). See Extension Cord
Chart on page 2.
