bones, toys, and other objects that could be tripped over or thrown by the blade. Thrown
objects can cause serious personal injury.
• Plan your mowing pattern in such a way as to avoid discharging material toward roads,
sidewalks, bystanders, etc. Do not discharge material against a wall or obstruction. Doing so

BATTERY & CHARGER
CAUTION
Use only greenworks approved replacement batteries, other batteries may cause injury or
damage to the mower. Use only with GREENWORKS battery LB60A01.
BATTERY SAFETY RULES
• Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards when not using your battery tool or when
changing accessories. Following this rule will reduce the risk of electric shock, re, or serious
personal injury.
• Do not place battery tools or their batteries near fire or heat. This will reduce the risk of
explosion and possibly injury.
• Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has
been dropped or received a sharp blow. A damaged battery is subject to explosion. Properly
dispose of a dropped or damaged battery immediately.
• Batteries can explode in the presence of a source of ignition, such as a pilot light. To reduce
the risk of serious personal injury, never use any cordless product in the presence of open
flame. An exploded battery can propel debris and chemicals. If exposed, flush with water
immediately.Do not charge battery tool in a damp or wet location. Following this rule will
reduce the risk of electric shock.
• For best results, your battery tool should be charged in a location where the temperature is
more than 42.8°F but less than 104°F. To reduce the risk of serious personal injury, do not
store outside or in vehicles.
• Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes
in contact with your skin, wash immediately with soap and water. If liquid gets into your eyes,
ush them with clean water for at least 10 minutes, then seek immediate medical attention.
Following this rule will reduce the risk of serious personal injury.
• When battery pack is not in use, keep it away from other metal objects like: paper clips, coins,
keys, nails, screws, or other small metal objects that can make a connection from one terminal
to another. Shorting the battery terminals together may cause sparks, burns, or a re.
• Always remove battery pack from your tool when you are assembling parts, making
adjustments, cleaning, or when not in use. Removing battery pack will prevent accidental
starting that could cause serious personal injury.
• Always remove battery pack before storing the device. When battery becomes fully charged,
unplug the charger from the power supply and remove the battery pack from the charger.
• Always wear eye protection with side shields marked to comply with ANSI Z87.1, along with
hearing protection. Failure to do so could result in objects being thrown into your eyes and
other possible serious injuries.

77
SAFETY INFORMATION

cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to
clean battery pack.
PROPER BATTERY CARE
Off-season storage
To obtain the longest possible battery life, we suggest the following:
• Remove the battery pack from the charger once it is fully charged and ready for use.
For battery pack storage longer than 30 days:
• Store the battery pack where the temperature is below 80°F and away from moisture.
• Store battery packs in a 30% - 50% charged condition.
• Every two months of storage, charge the pack as normal.
CHARGER SAFETY RULES
• Charge the mower battery in a dry area that is protected from the weather. Do not expose the
mower or the charger to rain. Do not charge the battery in a wet location. Operate the battery
charger in temperatures between 42.8°F and 104°F. In order to reduce the risk of electric
shock, use only the charger that is provided by the manufacturer to charge the battery.
• DO NOT MISUSE THE CHARGE CORD. Never carry the charger by the cord. Do not
disconnect the charger from the outlet or from the mower by pulling the charger cord.
• Do not use a damaged charger. Replace the charger cords or the charger immediately.
• Keep the mower and the charger away from water, heat sources (radiators, heaters, stoves,
etc.), ames, and chemicals.
• Make sure the battery pack is secured in the charger before beginning operation.
• The battery pack will become slightly warm to the touch while charging. This is normal and
does not indicate a problem.
• Do not place the charger and battery pack in an area of extreme heat or cold. They will work
best at normal room temperature.
• When batteries become fully charged, unplug the charger from the power supply and remove
the battery pack.
