Battery + Charger Safety Instructions

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 confirm that incorrect use and poor care of high- performance batteries are the main factors responsible for personal and/or product damage.

WARNING! Use only approved replacement batteries;
other batteries may damage the lawn mower and cause it to malfunction, which can lead to serious personal injury.

CAUTION! To reduce the risk of injury, charge the
iON100V-5AMP battery pack only in their compatible charger (model iON100V- RCH). Other types of chargers present risk of fire, 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 flammable materials) because sparks may be generated when inserting or removing the battery pack, which could lead to a fire.
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 flames near a charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery is 50°F (10°C) to 104°F (40°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 fire 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 120V 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 fire, electric shock or personal injury.
Unplug charger when not in use  Make sure to remove battery pack from unplugged chargers.

WARNING! To reduce the risk of electric shock,
always unplug the charger before performing any cleaning or maintenance. Do not allow water to flow 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, fire 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 fluids, wash the affected area with soap and water and rinse with vinegar. If eyes are exposed to battery chemicals, immediately flush 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 fire 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 influences

Wear suitable work clothes. Wear safety goggles.
Protect your cordless tool and the battery charger from moisture and rain. Moisture and rain can cause dangerous cell damage.
Do not use the cordless tool or the battery charger near vapors and flammable liquids.
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).
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.
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.
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%).
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.
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

The battery packs (model iON100V-2.5AMP or iON100V-5AMP) must be purchased separately for use with this cordless lawn mower are only partially charged. The battery packs have to be charged completely before you use the tool for the first time.
For optimum battery performance, avoid low discharge cycles by charging the battery packs frequently.
Store the battery packs in a cool place, ideally at 59°F (15°C) and charged to at least 40%.
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 aged battery packs are no longer capable of meeting the high power requirements needed for the proper operation of your cordless lawn mower, and therefore pose a safety risk.
Do not throw battery packs into an open fire as this poses a risk of explosion.
Do not ignite the battery packs or expose them to fire.
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.
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.
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 undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read the waste disposal information for proper battery disposal.
If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equipment for safety reasons. If this situation happens, stop the tool and let the battery cool down for a few minutes before restarting.
Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explosion.

Information about the charger and the charging process

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 different mains voltage.
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 qualified 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).
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack and the cordless tool out of the reach of children.
Do not use the battery charger to charge other cordless tools.
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.
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.
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 suffered dangerous damage (exhaustive discharge).
Charging batteries at a temperature below 50°F (10°C) will cause chemical damage to the cells and may cause a fire.
Do not use batteries that have been exposed to heat during the charging process, as the battery cells may have suffered dangerous damage.
Do not use batteries that have suffered curvature or deformation during the charging process or those that exhibit other atypical symptoms (gassing, hissing, cracking, etc.)
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.

Charging the Battery Packs

1. Flip open the battery compartment cover, push the battery
releasing button to release the battery pack. Pull the
battery out of the equipment. (Fig. 4).

2. Check that the main voltage is the same as that marked
on the rating plate of the battery charger. Then, insert the
charger’s plug into the electrical wall outlet. When you
plug in the charger, the red light will illuminate steadily
(Fig. 5).

CAUTION! Charger iON100V-RCH is rated for
100 – 120 volt AC only. DO NOT plug the charger into any
outlet that will provide power with a higher voltage.
Over voltage charging will be harmful to both the battery and
charger, and may cause the charger to burn out.

3. Place the battery pack into the charger by sliding the
pack as shown until it clicks into the position. When the
battery is inserted properly, the green light will slowly
flash to indicate that the battery is charging. The red light
will turn off. You will also hear a fan sound (Fig. 6).

4. When the green light stays on, the battery is fully charged
(Fig. 6).

NOTE: If the green light is off while the red light flashes slowly,
this indicates a temperature abnormality (i.e. that the
battery pack is too hot). If the green light is off while the
red light flashes rapidly, this indicates there’s something
wrong with the charger or the battery. Wait for a while and
try to reinsert the battery into the charger. If the situation still
persists, contact Snow Joe® + Sun Joe® customer service at
1-866-SNOWJOE (1-866-766-9563).

5. A fully discharged iON100V-5AMP battery pack with an
internal temperature in the normal range will fully charge
in 1 hr 40 minutes (between 50ºF/10ºC and 104ºF/40ºC).
Heavily discharged battery packs may take longer to
charge completely.
6. When charging is complete, remove the battery from the
charger by pulling the battery backward to unlock it from
the charger (Fig. 7).

7. Timely recharging of the battery will help prolong the
battery’s life. You must recharge the battery pack when
you notice a drop in the equipment’s power.

Operation

This lawn mower is intended for private residential use to cut
grass in small lawns and gardens. This lawn mower is not
intended to cut grass in public parks, playing fields, farms or
forests. Do not use this lawn mower for any application other
than that for which it is intended.

Adjusting the Cutting Height

This cordless lawn mower is equipped with a 7-position height
adjustment lever to tailor grass cutting heights from 1.2 in. to
3.75 in. (30 mm to 95 mm). To change the cutting height of the
grass, follow the instructions below.

WARNING! Before making these adjustments, remove
the battery and the safety key from the lawn mower and wait
until the rotating blade has come to a complete standstill.

ALWAYS FOLLOW ALL SAFETY PRECAUTIONS AND
RECOMMENDATIONS LISTED PREVIOUSLY IN THIS
MANUAL.

1. Power off the lawn mower and remove the battery and the safety key.
2. Push the cutting height adjustment lever to the outside of the original slot (Fig. 14).

(3) 1.97 in. (50 mm)
(4) 2.36 in. (60 mm)
(5) 2.76 in. (70 mm)
(6) 3.35 in. (85 mm)
(7) 3.75 in. (95 mm)

4. Reinsert the battery and the safety key to the lawn mower
and resume normal use.

Starting + Stopping

WARNING! Before switching on the 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 mower in tall grass.
1. Make sure the unit’s switch lever is not squeezed on.
Insert the battery and the safety key in their slots (Fig. 15).
Close the battery compartment cover.

2. To start the machine, press and hold the safety lock button
while pulling the switch lever toward you (Fig. 16).

3. Once the machine powers on, release the safety lock
button and proceed with operation.
4. To stop the mower, release the switch lever.

WARNING! The mower blade will continue to rotate for
a brief period after the unit has been switched off. Do not tilt or
carry the unit while the motor is still running and do not touch
the blade while it is still rotating. Failure to comply could result
in severe personal injury.

Using the Self-Propelled System

The cordless lawn mower is equipped with a variable-speed
self-propelled system, which is independent and can be
operated without the blade rotation. For example, when you
have completed cutting your lawn, you can use the
self-propelled system to propel the mower back to your
storage location without blade rotation. Or you may choose to
operate the mower as a non-self-propelled mower to maximize
battery run time.

To operate the self-propelled system without blade rotation,
push and hold the self-propel lever to the handle. To turn off
the self-propel system, release the self-propel lever (Fig. 17).
The system has variable speeds. Adjust the speed by turning
the speed-adjusting dial as shown (Fig. 17).

To operate the self-propelled system with the blade rotating for cutting:
1. Start the lawn mower as indicated by step 1 to step 3 in
Starting + Stopping section.
2. While holding the switch lever against the handle with
your left hand, push the self-propel lever to the handle
with your right hand.
3. Proceed with operation with both hands holding the
self-propel lever and the switch lever together with the
soft grip (Fig. 18).

NOTE: When the self-propelled system is turned off, the lawn
mower may lock itself from mowing backwards. In this case,
simply push ahead slightly and then move the mower back
as needed.
During operation, it may be easier to mow around an object
with the self-propelled system turned off.

WARNING! To reduce the risk of injury, never attempt
to override the operation of the switch or self-propelled
system. Use the self-propelled system for its intended
purpose only.

Grass Bag Filling Level Indicator

1. The grass bag is equipped with a filling level indicator
window that is opened by the airflow that the lawn mower
generates during operation (Fig. 18).
2. If the flap closes during mowing, this indicates that the
grass bag is full and must be emptied (Fig. 19).

NOTE: To ensure that the filling level indicator functions
properly, keep the holes under the flap clean and permeable.

Mowing Tips

WARNING! 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 replace as needed, 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/
self-propelled speed in order to allow for a more effective
cut and a proper discharge of the clippings. For a healthy
lawn, always cut off 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 off 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.

WARNING! If you strike a foreign object, stop the motor
and remove the battery. Thoroughly inspect the mower and
repair any damage before resuming work.
• IMPORTANT! Never open the ejector flap 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 flap and grass
collection bag. Switch off 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.
• For effective mulching, do not cut wet grass; it tends to
stick to the underside of the deck, preventing the proper
mulching of grass clippings. The best time to mow grass
is in the late afternoon, when the grass is dry and the
newly cut area will not be exposed to direct sunlight.
• For the best mulching performance, set the cutting height
to remove approximately one third of the grass length,
ideally no more than 1.5 in. at one time. If the grass is
overgrown, it may be necessary to increase the cut height
to make it easier to mow and to prevent overloading
the motor. Slow your cutting pace in tall or thick grass
conditions. For mulching extremely thick or tall grass, it is
advisable to first cut at a high cut-height setting, and then
re-cut to the final cut height. Otherwise, make narrower
cuts and mow slowly. ALWAYS MAKE SURE THAT THE
BLADE IS SHARP

Maintenance + Care

WARNING! Before cleaning, repairing or inspecting the
mower, stop the machine, remove the battery and the safety
key. 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 hand brush.
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 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 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 fine 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:
1. Disconnect the power supply to the mower by removing
the batter and the safety key.
2. Turn the mower on its side to expose the underside of the
blade housing.
3. Check the blade.
a. If the blade is blunt or has minor wear, then resharpen.
b. If the blade shows signs of major wear or damage
(i.e. gouged, bent), replace.

WARNING! An excessively vibrating mower indicates
that the blade is not properly balanced or has become
deformed from striking an object. In this case, the blade must
be repaired or replaced. Please follow the proper maintenance
procedures for blade care.

Blade Replacement

IMPORTANT: Only use original replacement parts specified
for this mower. The use of parts that do not meet the original
equipment specifications may lead to improper performance of
the lawn mower, may compromise operator safety.
1. Remove the battery and the safety key from 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 a 27 mm lug wrench (not provided), remove
the lug nut securing the blade by turning the lug nut
counterclockwise, then carefully remove the blade
(Figs. 20 to 21).

5. Fit the new blade on the same position and secure with
the original lug nut (Fig. 22).
