OPERATING INSTRUCTIONS
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 Care and 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, wires,
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 in. (10 cm), mow the
lawn twice in order to reduce the grass height to a maximum of 3-1/4 in. (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.
WARNING
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.
5. Emptying the grass catcher bag
• Stop mower, allow blades to completely stop, and
remove the battery.
5
• 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.

CARE AND MAINTENANCE
Replacing the cutting blade
WARNING
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 Kobalt replacement blade (Item #0812963, sold separately).
• 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 nut is being
removed.
• Using an adjustable wrench or 15mm socket (not
included), loosen the blade bolt (R) and remove the
blade (Q). Turn the bolt counterclockwise to loosen it
and clockwise to tighten it.
• Remove the bolt and the blade.
• To re-install the blade, position the blade with the
cutting edges toward the ground. Assemble the bolt as
shown. Using a socket or wrench, turn the blade bolt
“CLOCKWISE” in order to secure the blade.

WARNING
• 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, remove the battery, and then tilt the mower on its side, and scrape it
clean using an appropriate tool.

CARE AND 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 Replacing the cutting blade
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. Ensure that the handles “click” or lock into
place in the storage position.
• Remove the battery and store it in a cool dry location.
STORAGE SWITCH:
When the handle is rotated into the fully locked storage position, the mower is equipped with a storage switch that will disable the mower from running in the storage position. The storage switch does

Service
Servicing requires extreme care and knowledge and should be performed only by a qualied service
technician. For service, it is suggested you return the product to your nearest AUTHORIZED SERVICE CENTER for repair. When servicing, use only identical replacement parts.
WARNING
• When servicing the mower, use only identical replacement parts that are available from the man-
ufacturer. In order to obtain replacement parts, call the toll-free helpline, at 1-888-356-2258. The
use of parts that do not meet the original equipment specications may lead to improper performance, and may compromise safety.
• Before cleaning, repairing, or inspecting; verify that the blade and all moving parts have come to a
complete stop. Remove the battery when making any adjustments or when any of the four wheels
must be lifted off the ground.
• Follow the instructions for lubricating and changing accessories.
• Keep the handles dry, clean, and free of oil and grease.
• In order to reduce the risk of re, keep the motor free of grass, leaves, and debris build-up.
• Check the blade and motor mounting bolts for proper tightness frequently. Visually inspect blade
for damage (e.g., bent, cracked, or worn).
• For best and safest performance, maintain the mower with care. Keep the mower blade sharp and
clean. Mower blades are sharp and can cut. Wrap the blades or wear gloves, and use extra caution when servicing.
• Keep all nuts, bolts, and screws tight in order to be sure that the equipment is in safe working
condition.
• Never tamper with safety devices. Check them regularly for proper operation.
• After striking a foreign object, stop the motor. Thoroughly inspect the mower for any damage. Re-
pair any damage before operating the mower.
• The grass catcher components, discharge cover, and trail shield are subject to wear and damage,
which could expose moving parts or allow objects to be thrown. As a safety precaution, check
these components frequently, and immediately replace any parts that show signs of wear, or that
are cracked or broken. Use original equipment manufacturer's (OEM) parts only, as listed in this
manual.
• When it is not in use, store the mower indoors in a dry area, and out of the reach of children.
