using the string trimmer 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 the tool with
nger on the trigger. Make sure the switch is o before
inserting the battery.
7. 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.
8. Do not overreach – Keep proper footing and balance at
all times.
9. Stay alert – Watch what you are doing. Use common
sense. Do not operate the string trimmer when you are
tired, or under the inuence of alcohol or drugs.
10. Disconnect the tool – Turn the string trimmer o and
remove the battery when: the unit is not in use; it is left
unattended; it is being examined because it is not working
correctly; the cutting line is being removed or changed;
or when the trimmer is being moved from one place to
another.
11. 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.
12. Maintain tools with care – Keep cutting lines sharp
and clean for best performance and to reduce the
risk of injury. Follow instructions for maintenance and
changing accessories. Repair the string trimmer only at an
authorized service facility. Keep handles dry, clean, and
free from oil and grease.
13. Checked for damaged parts – Before continuing to
use the string trimmer, 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 aect the tool’s operation. A guard or

Battery + Charger
Safety Instructions
NOTE: The battery and the charger are not included and must
be purchased separately. The iON100V-16ST-CT is compatible
with the following batteries (models iON100V-2.5AMP and
iON100V-5AMP) and charger (model iON100V-RCH). See page
19 for more information.
We pay a great deal of attention to the design of every battery
pack to ensure that we supply you with batteries that are safe,
durable and have a high energy density. The battery cells have
a wide range of safety devices. Each individual cell is initially
formatted and its electrical characteristic curves are recorded.
This data is then used exclusively to be able to assemble the
best possible battery packs.
Despite all the safety precautions, caution must always be
exercised when handling batteries. The following points must
be obeyed at all times to ensure safe use. Safe use can only
be guaranteed if undamaged cells are used. Incorrect handling
of the battery pack can cause cell damage.
IMPORTANT! Analyses conrm that incorrect use and poor
care of high-performance batteries are the main factors
responsible for personal and/or product damage.
mWARNING! Use only approved replacement batteries;
other batteries may damage the string trimmer and cause it to
malfunction, which can lead to serious personal injury.
mCAUTION! To reduce the risk of injury, charge the
iON100V-2.5AMP battery pack or the iON100V-5AMP battery
pack only in their compatible charger (model iON100V-RCH).
Other types of chargers present risk of re, personal injury, and
damage. Do not wire a battery pack to a power supply plug or
car cigarette lighter. Such misuse will permanently disable or
damage the battery pack.
• Avoid dangerous environments – Do not charge the
battery pack in rain, snow or in damp or wet locations.
Do not use the battery pack or charger in the presence of
explosive atmospheres (gaseous fumes, dust or ammable
materials) because sparks may be generated when inserting
or removing the battery pack, which could lead to a re.
• Charge in a well-ventilated area – Do not block the
charger vents. Keep them clear to allow for proper
ventilation. Do not allow smoking or open ames near a
charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery is
-4°F (-20°C) to 113°F (45°C). Do not charge the battery
outside in freezing weather; charge it at room temperature.
• Maintain charger cord – When unplugging the charger, pull
the plug, not the cord, from the receptacle to reduce the
risk of damage to the electrical plug and cord. Never carry
the charger by its cord or yank it by the cord to disconnect
it from the receptacle. Keep the cord away from heat, oil
and sharp edges. Make sure the cord will not be stepped
on, tripped over or subjected to damage or stress when the
charger is in use. Do not use the charger with a damaged
cord or plug. Replace a damaged charger immediately.
• Do not use an extension cord unless it is absolutely
necessary – Using the wrong, damaged or improperly
wired extension cord poses a risk of re and electric shock.
If an extension cord must be used, plug the charger into a
properly wired 18 gauge or larger extension cord with the
female plug matching the male plug on the charger. Make
sure that the extension cord is in good electrical condition.
• Charger iON100V-RCH is rated for 100 – 120 volt AC
only – The charger must be plugged into an appropriate
receptacle.
• Use only recommended attachments – Use of an
attachment not recommended or sold by the battery
charger or battery pack manufacturer may result in risk of
re, electric shock or personal injury.
• Unplug charger when not in use – Make sure to remove
battery pack from unplugged chargers.
2
mWARNING! To reduce the risk of electric shock,
always unplug the charger before performing any cleaning
or maintenance. Do not allow water to ow into the charger.
Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock
hazards.
• Do not burn or incinerate battery packs – Battery packs
may explode, causing personal injury or damage. Toxic
fumes and materials are created when battery packs are
burned.
• Do not crush, drop or damage battery packs – Do not
use the battery pack or charger if they have sustained a
sharp blow, been dropped, run over or have been damaged
in any way (i.e. pierced with a nail, hit with a hammer,
stepped on, etc.).
• Do not disassemble – Incorrect reassembly may pose
a serious risk of electric shock, re or exposure to toxic
battery chemicals. If the battery or charger are damaged,
please contact an authorized Snow Joe® + Sun Joe® dealer
or call the Snow Joe® + Sun Joe® customer service center
at 1-866-SNOWJOE (1-866-766-9563).
• Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth. If a
damaged battery pack leaks battery chemicals, use rubber
or neoprene gloves to safely dispose of it. If skin is exposed
to battery uids, wash the aected area with soap and
water and rinse with vinegar. If eyes are exposed to battery
chemicals, immediately ush with water for
20 minutes and seek medical attention. Remove and
dispose of contaminated clothing.
• Do not short circuit – A battery pack will short circuit if
a metal object makes a connection between the positive
and negative contacts on the battery pack. Do not place a
battery pack near anything that may cause a short circuit,
such as paper clips, coins, keys, screws, nails and other
metallic objects. A short-circuited battery pack poses a risk
of re and severe personal injury.
• Store your battery pack and charger in a cool, dry
place – Do not store the battery pack or charger where
temperatures may exceed 104ºF (40ºC), such as in direct
sunlight or inside a vehicle or metal building during the
summer.
Protection from environmental inuences
1. Wear suitable work clothes. Wear safety goggles.
2. Protect your cordless tool and the battery charger from
moisture and rain. Moisture and rain can cause dangerous
cell damage.
3. Do not use the cordless tool or the battery charger near
vapors and ammable liquids.
4. Use the battery charger and cordless tools only in dry
conditions and at an ambient temperature of 50˚F – 104°F
(10°C – 40°C).
5. Do not keep the battery charger in places where the
temperature is liable to reach over 104°F (40°C).
In particular, do not leave the battery charger in a car that
is parked in the sunshine.
6. Protect batteries from overheating. Overloads,
overcharging and exposure to direct sunlight will result
in overheating and cell damage. Never charge or work
with batteries that have been overheated – replace them
immediately, if possible.
7. Store the charger and your cordless tool only in dry
locations with an ambient temperature of 50˚F – 104°F
(10˚C – 40°C). Store your lithium-ion battery pack in a
cool, dry place at a temperature of 50˚F – 68°F
(10˚C – 20°C). Protect the battery pack, charger and
cordless tool from humidity and direct sunlight. Only place
fully charged batteries in storage (charged to at least
40%).
8. Prevent the lithium-ion battery pack from freezing. Battery
packs that were stored below 32°F (0°C) for more than
60 minutes must be discarded.
9. When handling batteries, be wary of electrostatic charge.
Electrostatic discharges can damage the electronic
protection system and the battery cells. Avoid electrostatic
charging and never touch the battery poles.
Information about the battery
1. The battery packs (model iON100V-2.5AMP or iON100V-
5AMP) must be purchased separately for use with this
cordless string trimmer are only partially charged. The
battery packs have to be charged completely before you
use the tool for the rst time.
2. For optimum battery performance, avoid low discharge
cycles by charging the battery packs frequently.
3. Store the battery packs in a cool place, ideally at
59°F (15°C) and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural aging
process. The battery packs must be replaced at the latest
when its capacity falls to just 80% of its capacity when
new. Weakened cells in an aged battery pack are no
longer capable of meeting the high power requirements
needed for the proper operation of your cordless string
trimmer, and therefore pose a safety risk.
5. Do not throw battery packs into an open re as this poses
a risk of explosion.
6. Do not ignite the battery packs or expose them to re.
7. Do not exhaustively discharge batteries. Exhaustive
discharge will damage the battery cells. The most
common cause of exhaustive discharge is lengthy
storage or non-use of partially discharged batteries. Stop
working as soon as the performance of the batteries falls
noticeably or the electronic protection system triggers.
Place the battery packs in long-term storage only after
they have been fully charged.
8. Protect batteries and the tool from overloads. Overloads
will quickly result in overheating and cell damage inside
the battery housing even if this overheating is not apparent
externally.
9. Avoid damage and shocks. Immediately replace batteries
that have been dropped from a height of more than one
meter or those that have been exposed to violent shocks,
even if the housing of the battery pack appears to be
3
undamaged. The battery cells inside the battery may have
suered serious damage. In such instances, please read
the waste disposal information for proper battery disposal.
10. If the battery pack suers overloading and overheating,
the integrated protective cuto will switch o the
equipment for safety reasons. If this situation happens,
stop the tool and let the battery cool down for a few
minutes before restarting.
11. Use only original battery packs. The use of other batteries
poses a re risk and may result in injuries or an explosion.
Information about the charger and the
charging process
1. Please check the data marked on the rating plate of the
battery charger (sold separately). Be sure to connect the
battery charger to a power supply with the voltage marked
on the rating plate. Never connect it to a dierent mains
voltage.
2. Protect the battery charger and its cord from damage.
Keep the charger and its cord away from heat, oil and
sharp edges. Have damaged cords repaired without delay
by a qualied technician at an authorized Snow Joe® +
Sun Joe® dealer or call the Snow Joe® + Sun Joe®
customer service center at 1-866-SNOWJOE
(1-866-766-9563).
3. Electrical plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
grounded appliances. Unmodied plugs and matching
outlets will reduce the risk of electric shock.
4. Keep the battery charger, battery pack(s) and the cordless
tool out of the reach of children.
5. Do not use the battery charger to charge other cordless
tools.
6. During periods of heavy use, the battery pack will become
warm. Allow the battery pack to cool to room temperature
before inserting it into the charger to recharge.
7. Do not overcharge batteries. Do not exceed the maximum
charging times. These charging times only apply to
discharged batteries. Frequent insertion of a charged or
partially charged battery pack will result in overcharging
and cell damage. Do not leave batteries in the charger for
days on end.
8. Never use or charge batteries if you suspect that it has
been more than 12 months since the last time they were
charged. There is a high probability that the battery pack
has already suered dangerous damage (exhaustive
discharge).
9. Charging batteries at a temperature below 50°F (10°C) will
cause chemical damage to the cells and may cause a re.
10. Do not use batteries that have been exposed to heat
during the charging process, as the battery cells may have
suered dangerous damage.
11. Do not use batteries that have suered curvature or
deformation during the charging process or those that
exhibit other atypical symptoms (gassing, hissing,
cracking, etc.)
12. Never fully discharge the battery pack (maximum
recommended depth of discharge is 80%). A complete
discharge of the battery pack will lead to premature aging
of the battery cells.
