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 105ºF (40.5ºC), such as in direct sunlight or inside a vehicle or metal building during the summer.

Information about the battery

1. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
2. Store the battery pack in a cool place, ideally at 77°F (25°C) and charged to at least 40%.
3. Lithium-ion batteries are subject to a natural aging process. The 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 trimmer + edger, and therefore pose a safety risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion.
5. Do not ignite the battery pack or expose it to fire.
6. 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 battery falls noticeably or the electronic protection system triggers. Place the battery pack in storage only after it has been fully charged.
7. 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.
8. 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.
9. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equipment for safety reasons.
   
   Do not press the ON/OFF switch any more if the protective cut-off has been activated. This may damage the battery pack.

10. 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

1. Please check the data marked on the rating plate of the battery charger. 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.
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 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).
3. 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.
4. Keep the battery charger, battery pack and the cordless tool out of the reach of children.
5. Do not use the supplied 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 suffered dangerous damage (exhaustive discharge).
9. Charging batteries at a temperature below 41°F (5°C) will cause chemical damage to the cells and may cause a fire.
10. Do not use batteries that have been exposed to heat during the charging process, as the battery cells may have suffered dangerous damage.
11. 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.).
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.

Protection from environmental influences

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 flammable liquids.
4. Use the battery charger and cordless tools only in dry conditions and at an ambient temperature of 41ºF – 105°F (5°C – 40.5°C).

Secrets to a Long Lasting SharperBlade

CONGRATULATIONS! You are about to experience a faster, easier way of grooming your lawns edge and managing weeds.

First, you will notice that there are obvious differences between your SharperBlade and string line, among which are size and shape. These differences require you to operate your trimmer + edger slightly different:

1. Use MINIMAL pressure when edging against concrete, brick, or stone. Since the SharperBlade is more rigid than string, you may feel the need to put pressure on the blade while edging. The more pressure you apply, the FASTER the blade will wear. In contrast, the less pressure you apply against hard surfaces, the LONGER the blade will last! The SECRET is to keep the blade just off the hard surface.
2. NEVER FORCE your SharperBlade. High speed, along with an impact against any hard surface, may cause the blade to buckle near the center hub, and tear.
   The SECRET is to allow the SharperBlade to do ALL the work without extra effort.

Operation

TOOL ONLY
BATTERY + CHARGER SOLD SEPARATELY
In order to operate this cordless trimmer + edger you will need an iON+ 24V System battery and charger. For battery and charger options and specifications, or for more information visit sunjoe.com.

The cordless grass trimmer + edger is designed to cut grass and weeds under bushes, and on slopes and edges that cannot be reached with the lawn mower. The trimmer + edger must be used outdoors only, at an ambient temperature between 32ºF (0ºC) and 113ºF (45ºC).

Remove stones, small sticks and other objects from the cutting area. The SharperBlade continues to rotate for a few seconds after the trimmer + edger is switched off. Let the motor come to a complete stop before switching the trimmer + edger back on. Do not rapidly switch the trimmer + edger off and on.

Rocks or debris may ricochet or be thrown into eyes and face, cause blindness, or other serious injury.
Never lean over the trimmer head and always wear eye protection.

When operating the machine, check for the following:

• Wear eye protection and heavy clothing.
• Hold the rear handle with one hand and auxiliary handle with the other hand.
• Keep the trimmer + edger below your waist level.
• Cut only from your right to your left to ensure debris is thrown away from you. Without bending over, keep the trimmer + edger near and parallel to the ground.

Use only Sun Joe SharperBlade trimmer + edger replacement blade (Model SB10-BLD-3PK) with this unit. Other products will not work properly and will result in improper cutting head function or can cause serious injury. Do not use other materials such as steel blades, wire, string, rope, etc. Other materials can break off during cutting and become a dangerous missile that can cause serious injury.

Fanning action can be used for quick and easy clean up. Keep the SharperBlade parallel to and above the surfaces being swept and move the tool from side to side.

Edging

Because this procedure is close to the On/Off switch, make sure to remove the battery before converting the machine.

1. To convert your SharperBlade trimmer into an edger, slide the Twist-N-Groom locking collar downward and twist the handle clockwise to an angle of 180° while holding the pole. Release the collar and ensure it snaps into place.
   
2. Loosen the handle knob and adjust the auxiliary handle by pivoting it to a comfortable position. Tighten the handle knob to secure.
   
3. Use the edge of the guard as a guide when cutting near fences and walls.
   

Do not trim near electrical wires.

4. To convert your edger back to a trimmer, hold the handle, slide the Twist-N-Groom locking collar downward and twist the handle counterclockwise to an angle of 180° while holding the pole. Release the collar and ensure it snaps into place. Adjust the auxiliary handle as needed.

Proper Care for Battery and Charger

To reduce the risk of injury, always unplug the charger and remove the battery pack from the charger before performing any maintenance task. Never disassemble the battery pack or charger. Contact your Snow Joe + Sun Joe dealer or the Snow Joe® + Sun Joe customer service center for ALL repairs.

1. To reduce the risk of injury and damage, never immerse your battery pack or charger in liquid or allow any liquid to flow inside these components.
2. Clean out dust and debris from charger vents and electrical contacts by blowing with compressed air.
3. Use only a soft, clean and dry brush to clean the battery pack and charger, keeping away from all electrical contacts. Certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around battery packs, battery chargers or tools.
4. The iON+ 24V lithium-ion battery chargers have no serviceable parts.

Storage

Follow these recommendations for storing the grass trimmer + edger.

• Clean the grass trimmer + edger thoroughly before storing.
• Store the trimmer + edger in a stable and safe location out of the reach of children. Keep the trimmer + edger in a dry place where the temperature is not too hot or too cold.
• Do not store the grass trimmer + edger resting against the floor. Hang it by the upper handgrip so that the guard does not touch anything. If the guard rests against a surface, its shape and dimensions could be permanently altered, and could render the machine unsafe to use.

Battery and Charger Off-Season Storage

1. Do not expose your battery pack or charger to water, rain or allow them to get wet. This could permanently damage the charger and the battery pack. Do not use oil or solvents to clean or lubricate your battery pack as the plastic casing can become brittle and crack, causing a serious risk of injury.
2. Store the battery pack and charger at room temperature away from moisture. Do not store in damp locations where corrosion of terminals may occur. As with other battery pack types, permanent capacity loss can result if the pack is stored for long periods of time at high temperatures (over 120ºF/49ºC).
3. iON+ 24V lithium-ion battery packs maintain their charge during storage longer than other battery pack types.
   As a general practice, it is best to unplug the battery charger and remove the battery pack when they are not in use. Recharge the battery pack every 6 months to 50% capacity (2 lights on) during off-season storage to maintain optimal battery performance.

Battery Caution and Disposal

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

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.

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.

1. Batteries vary according to device. Consult your manual for specific information.
2. Install only new batteries of the same type in your product (where applicable).
3. 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.
4. Do not mix old and new batteries.
5. Do not mix Alkaline, Standard (Carbon-Zinc) or Rechargeable (Nickel Cadmium, Nickel Metal Hydride, or Lithium-Ion) batteries.
