Safety Instructions
All Operators Must Read These
Instructions Before Use
Before using this electric tool, carefully read and observe the
safety rules and instructions listed below. Before starting work,
make sure that you know how to stop the machine in case of
an emergency. The incorrect use of this machine could cause
serious injury. Keep these instructions in a safe place and on
hand so that they can be consulted when required.
mDANGER! The electric grass trimmer + edger should
only be used for cutting lawns and for trimming along the
borders of ower beds. Other uses of the trimmer + edger that
are not indicated in these instructions could damage the unit
or seriously injure the operator.
General Safety
1. Avoid dangerous environments – Do not use appliances
in damp or wet locations. Do not use in rain.
2. Keep children and bystanders away – Children and
other spectators, including pets, should be kept at least
50 feet (15 meters) away from the work area. When the
grass is cut, stones and debris contained in the grass can
be picked up by the trimmer + edger and dispersed into
the air. These ying projectiles can cause blindness or
other bodily injury.
3. Dress properly – Always wear suitable clothing when
using the trimmer + edger to prevent head, hand, or feet
injuries. Do not wear loose clothing or jewelry. They can
get caught in moving parts.
4. Use safety glasses – Also use safety footwear,
snug-tting clothing, protective gloves, hearing and
head protection.
5. Use the right tools – Do not use tools for any job except
that for which they are intended.
6. Avoid unintentional starting – Do not carry plugged-in
tool with nger on the trigger. Make sure the switch is o
before plugging in the tool.
7. Do not abuse the cord – Never carry the tool by the cord
or yank the cord to disconnect it from the receptacle.
Keep the cord away from heat, oil, and sharp edges.
8. Do not force the tool – It will do the job better and with
less likelihood of injury if it is used at the rate for which it
was designed.
9. Do not overreach – Keep proper footing and balance at
all times.
10. Stay alert – Watch what you are doing. Use common
sense. Do not operate the trimmer + edger when you are
tired, or under the inuence of alcohol or drugs.
11. Disconnect the tool – Turn the trimmer + edger o and
disconnect the plug when: the unit is not in use; it is left
unattended; it is being examined because it is not working
correctly; the power supply cable is damaged; the blade is
being removed or changed; or when the trimmer is being
moved from one place to another.
12. Store idle tools indoors – When not in use, tools should
be stored indoors in a dry and high or locked-up place out
of the reach of children.
13. Maintain tools with care – Keep cutting edges sharp
and clean for best performance and to reduce the risk
of injury. Follow instructions for lubricating and changing
accessories. Inspect the trimmer + edger periodically and
replace if damaged. Repair the trimmer + edger only at an
authorized service facility. Keep handles dry, clean, and
free from oil and grease.
14. Checked for damaged parts – Before continuing to
use the trimmer + edger, a guard or other part that is
damaged should be carefully checked to determine that
it will operate properly and perform its intended function.
Check for the alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any other
condition that may aect the tool’s operation. A guard or
other part that is damaged should be properly repaired or
replaced by an authorized service center unless indicated
elsewhere in this manual.
mCAUTION! The safety guard is critical to the safety of
the operator and the safety of people standing within a safe
distance of the trimmer + edger. The safety guard keeps the
unit in good working order and must always be in place during
operation. Failure to have the guard in place during operation
is dangerous and will void the warranty.
15. Keep away from the cutting line – It can seriously injure
the skin.
16. Do not try to stop the cutting device with your hands –
Always let it come to a stop by itself.

2
17. Inspect electrical cables – The insulation of the power
cord should be perfectly intact. If the power cord is
damaged or shows any signs of cracks, do not use the
trimmer. Contact your authorized Snow Joe®+ Sun Joe®
dealer or call the Snow Joe®+ Sun Joe®customer service
center at 1-866-SNOWJOE (1-866-766-9563).
mCAUTION! The trimmer line spool will continue to rotate
after turning the trimmer OFF. Wait until the trimmer line spool
has completely stopped before making contact.
• Only use the same type of line originally provided with
the tool.
• Do not use the unit to cut grass that is not in contact with
the ground.
• Do not switch the string trimmer + edger ON in enclosed or
poorly ventilated spaces or in the presence of ammable
and/or explosive substances such as liquids, gases, and
powders.
• The user of the trimmer + edger is responsible for any
damage sustained by third parties that has been caused by
the grass trimmer within the working area.
• Only cut during broad daylight or with adequate
articial light.
• Do not cross roads or gravel paths while the unit is
still running.
• When the trimmer + edger is not in use, store it in a dry
place and out of the reach of children.
• The trimmer + edger must be operated in a vertical position,
perpendicular to the ground.
• Check regularly that all screws are properly secured.
Electrical Safety
1. Ground fault circuit interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for
this electric grass trimmer. 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.
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.
mWARNING m
Electric shock may cause SEVERE INJURY or
DEATH. Heed these warnings:
• Do not allow any part of the electric grass trimmer
+ edger 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.
• 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.

the unit.
• Only use an extension cable that is rated for outdoor use.
Keep the extension cord away from the cutting area, sharp
edges, heat, fuels, damp areas, and oily surfaces.
• Damage to unit – If the trimmer + edger strikes a foreign
object or becomes entangled with it, stop the tool
immediately. Unplug it, check for damage, and have any
damage repaired before proceeding with operation. Do
not operate the tool with a broken hub or spool. Contact
your authorized Snow Joe®+ Sun Joe®dealer or call
the Snow Joe®+ Sun Joe®customer service center at
1-866-SNOWJOE (1-866-766-9563).
• Damage to cord – Keep power cord away from the rotating
line. If you damage the cord, unplug it from the power
supply before moving the tool or examining the damage.
A damaged cord must be replaced before further use.
• Do not operate portable electric tools in gaseous or
explosive atmospheres – Motors in these tools normally
spark, and the sparks might ignite fumes.
• Maintain appliances with care – Follow instructions for
lubricating and changing accessories. Inspect extension
cords periodically and replace if damaged. Keep handles
dry, clean, and free from oil and grease.
Double-Insulated Appliances
In a double-insulated appliance, two systems of insulation
are provided instead of grounding. No grounding means is
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
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 grass trimmer + edger 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 grass trimmer
+ edger only as described in this manual.

Trimming
• Wear non-slip gloves for maximum grip and protection.
• For the best cutting action against walls, fences, and in high
grass, move the grass trimmer slowly so grass is cut with
the tip of the high speed nylon line.
• Avoid dragging the grass trimmer and string spool hub in
contact with the ground.
• Trim only when grass and weeds are dry.
NOTE: As the weather becomes cooler, the tendency for the
nylon line to break becomes greater. DO NOT USE WHEN
TEMPERATURE IS BELOW 50ºF (10ºC).
• Cut tall grass from top down. This will prevent grass from
wrapping around the shaft housing and string head which
may cause damage from overheating.
• If grass becomes wrapped around the string head:
–Stop the trimmer.
– Unplug the string trimmer.
– Remove the grass.
• Hold the grass trimmer with your right hand on the rear
handle and your left hand on the front auxiliary handle.
The trimmer + edger should be held at a comfortable
position with the rear handle about hip height.
mWARNING! Always hold the trimmer away from
body. Any contact with the grass trimmer cutting head while
operating can result in serious personal injury.
• The life of your nylon line is dependent upon following
instructions for proper use, as well as what is being cut,
and where the cutting is being done.
mWARNING! Remove stones, loose pieces of wood, and
other objects from the cutting area. The string continues to
rotate for a few seconds after switching o the trimmer. Let the
motor come to a complete stop before resuming operation.
Do not rapidly switch the trimmer o and on.
mCAUTION! Always wear eye protection.

1. Hold the trimmer at an angle of approximately 10 – 30
degrees to the work area (Fig. 16).
2. Slowly swing the trimmer from side to side (Fig. 17).
3. Do not overload your trimmer; instead, take small “bites”
of grass, working from the top to the bottom. This will
keep the machine operating at high speed and will greatly
improve its cutting eciency (Fig. 18).
Edging
1. To convert for maintenance edging, turn OFF and unplug
the tool.
2. To use the edger guide + ower guard, ip it down from its
stored position (Fig. 19).

4. Rotate the whole unit 180 degrees. The tool is now ready
to be used in edger mode (Fig. 21).
5. Use the edge of the guard as a guide when cutting near
fences and walls (Fig. 22).
6. Move the edger in a backwards direction when trimming
around edges to avoid damage.
mWARNING! Do not trim near electrical wires.
Advancing Strings
NOTE: Your trimmer uses 0.063 in. (1.6 mm) diameter nylon
line to cut grass and weed quickly and easily. In time, the
tip of the nylon line will become worn and the auto-feed
mechanism will automatically feed and trim a fresh length of
line. The cutting line will wear faster if the cutting is done along
sidewalks or other abrasive surfaces or heavier weeds are
being cut.
The trimmer + edger is equipped with an auto-feed head.
Bumping the head to try to advance the string will damage
trimmer.
1. With the unit running, release the ON/OFF switch trigger.
2. Wait two seconds, and press the ON/OFF switch trigger.
NOTE: The strings will extend approximately 1/4 in. with each
stop and start of the switch trigger until the strings reach the
length of the safety guard.
3. Resume the trimming + edging.
mWARNING! Do not operate the grass trimmer + edger
in a tree, on a ladder, or on a scaold; this is extremely
dangerous.
mWARNING! Do not bump the unit on ground in attempt
to feed line or for any other purpose.
Maintenance
mWARNING! Make sure to unplug your electric grass
trimmer + edger before inspecting its parts.
mWARNING! Always wear protective gloves during
maintenance tasks. Do not carry out maintenance when the
motor is running or hot.
• Your trimmer line can dry out over time. To keep your line in
top condition, store spare pre-wound spools or bulk line in
a plastic resealable bag with a tablespoon of water.
• Never use water or chemical cleaners to clean your grass
trimmer + edger. Wipe it clean with a dry cloth.
• Plastic parts may be cleaned by using mild soap and a
damp rag.
• Always store your grass trimmer + edger in a dry place.
Do not allow any liquid to get inside it.
