PROPER CARE FOR BATTERY
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.
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 45°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

SLOPE GAUGE (See Figure 10)
W ARNING
Slopes are a major factor related to accidents involving slips and falls, which can result in severe
injury. Operating the mower on a slope requires extra caution. If you feel uneasy on a slope,
do not mow it. For your safety, use the slope gauge that is included as part of this manual to
measure slopes before operating this unit on a sloped or hilly area.
• Mow across the face of a slope, and never up and down. Exercise extreme caution when
changing direction on a slope.
• Watch for holes, ruts, rocks, hidden objects, or bumps that may cause a slip or a trip. Tall
grass can hide obstacles.
• Always be sure of your footing. If you feel like you are losing your balance, release the blade/
motor control handle immediately. The blade will stop rotating within 3 seconds.
• Do not mow near drop-offs, ditches, or embankments, because you could lose your footing or
balance.
• Do not mow a slope that has an angle of greater than 15°, as determined using the slope gauge.
• Do not mow wet or damp grass. Unstable footing can cause slipping.
W ARNING
Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2 1/2 feet [.75 m]
every 10 feet [3 m]). Mow across the face of a slope, and never up and down.

OPERATING YOUR LAWN MOWER
MOWING TIPS
NOTE: A sharp blade will greatly enhance the performance of the mower, especially when cutting high grass.
Be sure to check the blade and to sharpen it at least once per year, as described in the Maintenance section.
• Verify that the lawn is free of stones, sticks, wires, and other objects that could damage
the blades or the motor. These objects could be accidentally thrown by the mower in any
direction, and could cause serious personal injury to the operator and to others. In order to
prevent electric shock, do not operate the mower in damp or wet conditions.
• Do not mow in circles. Travel back and forth across the lawn.
• When cutting thick grass, reduce walking 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 of the total length of the grass. The
average lawn should be approximately 1 1/2 to 2” (3.8 to 5 cm) long during cool months, and
between 2" to 3 1/4" (5 cm to 8.3 cm) long during hot months. If there is growth, the lawn
should be cut in the fall.
MULCHING TIPS
NOTE: INSPECT THE AREA WHERE THE MOWER IS TO BE USED, AND REMOVE ALL STONES,
STICKS, WIRE, BONES, AND OTHER DEBRIS THAT MIGHT BE THROWN BY THE ROTATING BLADE.
• Release the bail lever to turn the mower OFF when crossing any graveled area (stones can be
thrown by the blade).
• Set mower to the highest cutting height when mowing on uneven ground or in tall weeds.
• For effective mulching, do not cut wet grass, because it tends to stick to the underside of
the deck, preventing proper mulching of grass clippings. New or thick grass may require a
narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing
has been delayed and the grass has been allowed to grow longer than 4" (10 cm), mow the
lawn twice in order to reduce the grass height to a maximum of 3 1/4” (8.3 cm).
• Walk at a steady pace. Overlap the cutting rows. Do not let the grass get too tall. If the grass
gets too long, start at the highest cutting position and work down to the desired cutting height.
W ARNING
If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower
for any damage. Repair any damage before operating the mower. Excessive vibration of the mower
during operation is an indication of damage. Thoroughly inspect the mower and repair any damage
before operating the mower.

OPERATING YOUR LAWN MOWER
EMPTYING THE GRASS CATCHER BAG (See Figure 11)
• Stop mower, allow blades to completely stop, and remove the battery.
• Lift the rear discharge cover.
• Lift the grass catcher bag by its handle to remove from mower.
• Empty grass clippings.
• Lift the rear discharge cover and reinstall the grass catcher bag as described earlier in this
manual.

MAINTENANCE
REPLACING THE CUTTING BLADE (See Figure 12-13)
W ARNING
Always protect your hands by wearing heavy gloves and/or wrapping the cutting edges with rags
or other materials when performing any maintenance on the blades. ALWAYS remove the battery
when servicing or transporting the mower.
Use only a GREENWORKS replacement blade (Item#: 2903402).
• REMOVE BATTERY.
• While wearing leather padded gloves, wedge a block of wood between the blade and the
mower deck in order to prevent the blade from turning when the bolt (1) is being removed.
• Using an adjustable wrench or 27 mm socket, loosen the bolt (1) and remove the blade (2).
Turn the bolt “COUNTERCLOCKWISE” to loosen it and “CLOCKWISE” to tighten it.
• Remove the bolt (1) and the blade (2).
• To re-install the blade, position the blade with the cutting edges toward the ground. Assemble
the bolt as shown. Using a 27 mm socket or wrench, turn the blade nut "CLOCKWISE” in
order to secure the blade.
NOTE: Be sure to replace the parts in the exact order in which they were removed. When installing the cutting
blade, verify that it is installed with the curved ends pointing toward the mower deck, and not toward the
ground. Refer to the schematic drawing on page 30 of this manual.

MAINTENANCE
CLEANING THE MOWER
W ARNING
In order to reduce the risk of electric shock, do not expose the mower to water. The underside of
the mower deck should be cleaned after each use, because grass clippings, leaves, dirt, and other
debris will accumulate, which will cause rust and corrosion.
Remove any build-up of grass and leaves on or around the motor cover (do not use water).
Occasionally wipe the mower clean with a dry cloth. If debris builds up on the underside of the
mower during use, stop the motor, disconnect it from the battery, and then tilt the mower on its
side, and scrape it clean using an appropriate tool.
MAINTENANCE
STORING THE MOWER
The following steps should be taken in order to prepare the lawn mower for storage.
• Clean the mower as described in the previous section.
• Inspect the blade, and replace it or sharpen it, if required (refer to the Maintenance section).
• Store the mower in a dry, clean location. Do not store it next to corrosive materials, such as
fertilizer or rock salt.
• Store the mower indoors, in a cool, dry place, out of the reach of children. Do not cover the
lawn mower with a solid plastic sheet. Plastic coverings trap moisture around the mower,
which causes rust and corrosion.
The handle may be folded away completely for storage.
(See Figure 14)
• Pull and rotate the handle knobs (1) 90° on both sides to loosen the lower handles (2) on
both sides. Fold the lower handle forward. Make sure not to bend or kink the power cord.
• Remove the battery and store it in a cool dry location, if possible. Charge the battery every
two months when not in use in order to increase its life.
• Remove the battery and store in a secure location out of the reach of children.
