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 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 packs can cause cell damage.

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

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

WARNING! Do not use a battery pack or machine that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

Have your battery packs serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the battery packs is maintained.

CAUTION! To reduce the risk of injury, use only official 24V iON+ designated chargers with the 24V iON+ battery packs. The use of other batteries or chargers poses a risk of fire, personal injury and damage. Do not modify or attempt torepair the machine or the battery packs except as indicated in the instructions for use and care. Do not wire a battery pack to a power supply or car cigarette lighter, as such misuse will permanently disable or damage the battery packs.

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.

Avoid dangerous environments – Do not charge the battery packs in rain, snow or in damp or wet locations. Do not use the battery packs 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 packs, 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 batteries are 41°F (5°C) to 105°F (40.5°C). Do not charge the batteries 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 16 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.
Do not expose the tool or battery packs to fire – Exposure to fire or temperatures above 265°F (130°C) may cause the battery packs to explode, causing personal injury or damage. Toxic fumes and materials are created when battery packs are ignited.
Use only recommended attachments – Use of an unapproved attachment may result in risk of fire, electric shock or personal injury.
Do not crush, drop or damage battery packs – Do not use the battery packs 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 batteries or charger is damaged, 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) for assistance.
Battery chemicals cause serious burns – Never let a damaged battery pack contact the skin, eyes or mouth. If damaged, battery chemicals will react violently with air. Use rubber or neoprene gloves to safely dispose of the battery. If skin is exposed to battery chemicals, wash theaffected area with soap and water. If eyes are exposed to battery chemicals, immediately flush with water for 20 minutes and seek medical attention. Remove and dispose of contaminated clothing.
Risk of 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 abattery pack near anything that may cause a short circuit, such as paperclips, 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 packs and charger in a cool, dry place – Ideally, store the battery packs at 59°F (15°C) and charged to at least 40%. Do not store the battery packs or charger where temperatures may exceed 105ºF (40.5ºC), such as in direct sunlight or inside a vehicle, or where temperatures may drop below 41°F (5°C).
NOTE: Prevent the battery packs from freezing. Battery packs that were stored below 32°F (0°C) for more than 60 minutes must be discarded.
Charge before use – The battery packs supplied with your tool is only partially charged. The battery packs have to be fully charged before using the snow blower for the first time.
Battery Aging – Lithium-ion batteries are subject to a natural aging process. A battery pack 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 tool, and therefore pose a safety risk.
Do not exhaustively discharge the battery packs – A complete discharge will damage the battery cells. The most common cause of exhaustive discharge is lengthy storage. Stop working as soon as the performance of a battery falls noticeably or the electronic protection system triggers. For optimum battery performance, charge the battery packs frequently. Place the battery packs in storage only after it has been fully charged.
Do not overload the battery packs – Protect the tool and batteries from overloading. Overloads will quickly result in overheating and cell damage inside the battery housing even if it is not apparent externally. For safety reasons, the integrated protective cutoff will activate to switch off the equipment. After regular use, allow the battery packs to cool to room temperature before recharging them.
IMPORTANT! Do not attempt to turn on the tool if the protective cutoff has been activated. This may damage the battery packs.
Outlet voltage – Please check the data marked on the rating label of the battery charger. Be sure that the voltage of the power supply matches that marked on the rating label. Never connect it to a different mains voltage. Never modify the plug in any way. Do not use any adapter plugs with grounded tools.
Charger use – Do not use the supplied battery charger to charge other types of battery packs or tools.
Do not overcharge battery packs – Unplug the charger when not in use. Frequently overcharging the battery packs will result in cell damage. Do not leave batteries charging for days on end.
Battery pack abnormalities – Do not use batteries that have suffered swelling or deformation or those that exhibit other atypical symptoms (gassing, hissing, cracking, etc.).
Electrostatic discharge – When handling batteries, be wary of electrostatic charge. Electrostatic discharges can damage the electronic protection system and the battery cells. To avoid electrostatic discharges, never touch the battery terminals.

Operating Tips

WARNING! Foreign objects, such as rocks, broken glass, nails, wire, or string, can be picked up and thrown by the snow blower, causing serious personal injury. Remove all foreign objects from the area to be plowed before operating the snow blower.

Snow is best removed as soon as possible after snow fall.

Keep the area of operation free of foreign objects that can become thrown by the blades. Perform a thorough inspection of the area since some objects may be hidden from view by surrounding snow. If the snow blower hits an obstruction or picks up a foreign object during use, stop the snow blower, remove the battery, remove the obstruction, and inspect the unit for damage. Repair or replace any damaged part before restarting and operating the unit.
Keep children, pets, and bystanders away from the area of operation. Be aware that the normal noise of the machine when turned on may make it difficult for you to hear approaching people.
To clear an area, run unit in an overlapping series of paths. For large areas, start in the middle and throw snow to each side, so snow is not cleared more than once.
Note the wind direction. If possible, move in the same direction as the wind so that the snow is not thrown against the wind (and thus back into your face and on the just cleared path).
Do not push the snow blower with excessive force. Do not exceed the unit’s intake or throw rate.
Some parts of the snow blower may freeze under extreme temperature conditions. Do not attempt to operate the snow blower with frozen parts. If the parts freeze while the snow blower is in use, stop the snow blower, remove the battery, and inspect for frozen parts. Free all parts before restarting or operating the snow blower. Never force controls that have frozen.
For larger areas, a definite pattern of operation is required to thoroughly clean an area of snow. These patterns will avoid throwing snow in unwanted places, a well as eliminate the need for a second removal of snow (Fig. 18).
Pattern A: Throw the snow to the right or left side where it is possible. For areas such as a long driveway, it is advantageous to start in the middle. Plow from one end to the other, throwing snow to both sides.
Pattern B: If the snow can only be thrown to one side of the area to be cleared, start on the opposite side.

Install the new scraper bar and fasten it securely to the snow blower with the original sets of nuts, washers and bolts.

Replacing Auger Blades

During use, the auger blades will wear down over time, which will eventually cause incomplete cleaning. If the unit cannot plow snow completely and leaves snow on ground, consider changing the auger blades.

WARNING! Replacing the auger blades involves close operation with the auger and the blades. To avoid injury caused by unintentional starting, make sure the batteries are not inserted before proceeding with the operation, and wear heavy duty gloves during operation.

Tools Required (Not Provided):

10 mm wrench
13 mm wrench
Heavy duty gloves

In total there are 6 blade pieces fixed by 16 sets of screws, washers and nuts in the unit. When replacing worn auger blades, pay close attention to the order in which you remove them. Remove the 4 blade pieces on the sides first, and then the 2 blade pieces fixed on the middle steel plate. Assemble the new auger blades in the reverse order of the disassembly (Figs. 20 – 21).

To remove the first blade on the side, use a 10 mm wrench to hold the bolt steady, and use a 13 mm wrench to loosen and remove the nut. Repeat the operation to remove all 3 sets of bolt and nut, and gently remove the blade from the auger (Fig. 22).
Follow the same instruction to remove the other 3 blades located on the sides. Rotate the auger when working on the blades on the back.
After 4 blades on the side are removed, move to the two blade pieces that are fixed on the middle steel plate. Use the 10 mm wrench to hold the bolt steady, and use the 13 mm wrench to loosen and remove the nut. Repeat on the other nut and bolt set, and gently remove the blade from the central plate (Fig. 23).
Rotate the auger to expose the other blade on the plate. Follow the same instruction to remove it.
After all old blades are removed, follow the reverse order to assemble the new blades. Use the original sets of hardware to secure the blades on the auger.

Replacing Auger Belt

Tools Required (Not Provided):

10 mm wrench (2)
Heavy duty gloves

Position unit on a hard, flat, smooth level surface, with the batteries removed.
Use 2 10 mm wrenches to remove the bolts and nuts that are used to fix the right side panel. Then remove the right side panel to expose the belt, as shown (Fig. 24).

NOTE: The 2 bolts located on the left have 2 nuts on the back, while the other 4 bolts don’t. Use one 10 mm wrench to hold the left two bolts steady and remove the nuts with the other 10 mm wrench first, and then remove all the bolts.
Remove the drive belt by slowly turning the auger pulley counterclockwise while pulling the belt outwards (Fig. 25)
Install the new drive belt, rotating it onto the pulleys (Fig. 26).

Always dispose of your battery packs according to federal, state, and local regulations. Contact a recycling agency in your area for recycling locations.

CAUTION! Even discharged battery packs contain some energy. Before disposing, use electrical tape to cover the terminals to prevent the battery pack from shorting, which could cause a fire or explosion.

WARNING! To reduce the risk of injury or explosion, never burn or incinerate a battery pack even if it is damaged, dead or completely discharged. When burned, toxic fumes and materials are emitted into the surrounding atmosphere.

Batteries vary according to device. Consult your manual for specific information.
Install only new batteries of the same type in your product (where applicable).
Failure to insert batteries in the correct polarity, as indicated in the battery compartment or manual, may shorten the life of the batteries or cause batteries to leak.
Do not mix old and new batteries.
Do not mix Alkaline, Standard (Carbon-Zinc) or Rechargeable (Nickel Cadmium, Nickel Metal Hydride, or Lithium-Ion) batteries.
Do not dispose of batteries in fire.
Batteries should be recycled or disposed of as per state and local guidelines.
