• Inspect lawnmower cord periodically and if damaged, have it repaired by an authorized servicefacility.
• Only use approved replacement parts.
MOWING AREA
• Before mowing any area, thoroughly inspect the area for any hazards. Walk the area to ensure thereis
adequate traction and no holes, drop-offs, or hidden objects that could cause issues. Clear thearea
of objects such as rocks, wire, toys, etc., which could be thrown by the blades.

SLOPE OPERATION
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe
injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you
feel uneasy on it, do not mow it.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn
themachine. Tall grass can hide obstacles.
• Choose a low ground speed so you will not have to stop or shift while on a slope.
• Do not mow on wet grass. Tires may lose traction.
• Always keep the machine in gear when going down slopes. Do not shift to neutral and coast downhill.
• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blade(s)
andproceed slowly straight down the slope.
• Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction,

8 P0803466-00 v.2.0
SAFETY INFORMATION
which could cause the machine to roll over.
• Use extra care while operating machine with attachments; they can affect the stability of the machine.
Do not use on steep slopes.
• Do not try to stabilize the machine by putting your foot on the ground.
• Do not mow near drop-offs, ditches or embankments. The machine could suddenly roll over if awheel
goes over the edge or if the edge caves in.
CHILD SAFETY
Tragic accidents can occur if the operator is not aware of the presence of children. Children are often
attracted to the machine and the mowing activity. Never assume that children will remain where you last
saw them.

obscure your view of a child who may run into the path of the mower.
• Before and while backing, look behind and down for small children.
• Never carry children on the mower with you, even with the blade(s) shut off. They may fall off and
beseriously injured or interfere with safe machine operation. Children who have been given rides in
thepast may suddenly appear in the mowing area for another ride and be run over or backed over by
themachine.
USING A RAMP
• Use extreme caution when loading and unloading this mower onto a truck or trailer with a ramp.
• Use only a single, full-width ramp. This provides a surface for the mower frame to contact if the
unitstarts to tip backwards. It also reduces the risk of a wheel going off and the machine tipping over.
• Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and
thetrailer or truck.
• Become familiar with the mower’s controls and condent in its smooth operation before attempting
todrive it up or down a ramp.

SAFETY INFORMATION
BATTERY & CHARGER
CAUTION
Use only Greenworks approved replacement batteries, as other batteries may cause injury or damage to
the mower. Only to be used with Greenworks 82V Batteries.
BATTERY SAFETY RULES
• Battery-operated mowers and 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-
operated mower or when changing accessories. Following this rule will reduce the risk of electric
shock, re, or serious personal injury.
• Do not place battery-operated machines or tools -- or the batteries themselves -- near re 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, like a pilot light. To reduce the risk
of serious personal injury, never use any cordless product in the presence of an open ame. An
exploded battery can propel debris and chemicals. If exposed, ush 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-operated machine should be charged in a location where the
temperature is more than 0°C (32° F) but less than 45°C (113° 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 this 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.
• Charge batteries in an open, well-ventilated area away from spark and ames. Unplug charger before
connecting or disconnecting battery to/from the charging port. Always wear safety glasses and
protective clothing/gear. Use insulated tools.
• Sparks can cause a battery gas explosion, which will result in serious personal injury. Prevent the
battery terminals from touching any metal mower parts when removing or installing the battery. Do
not allow metal tools to short between the battery terminals and metal mower parts. Use insulated
tools. Always keep protective battery cover and rear cover in place.
• Follow rst aid directions for contact with battery uid. Get medical attention immediately.
• Incorrect battery cable routing could cause damage to the mower and battery cables. This can cause
sparks, which can cause a battery gas explosion that will result in serious personal injury.
