SLOPE GAUGE (See Figure 11)
W A R N I N G
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 A R N I N G
Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2 1/2’ [.75 m]
every 10’ [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 switch 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 A R N I N G
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 12-13)
• Stop the mower and allow blades to completely stop.
• Remove key and battery pack.
• Lift the rear discharge door.
• Lift the grass catcher by its handle to remove from mower.
• Empty grass clippings.
• Lift the rear discharge door and reinstall the grass catcher as described earlier in this manual.

MAINTENANCE
REPLACING THE CUTTING BLADE (See Figure 16-17)
W A R N I N G
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 key and
battery when servicing or transporting the mower.
Only use authorized replacement blades.
• Stop the motor and remove the key. Allow blade to come to a complete stop.
• Remove the battery pack.
• Turn the mower on its side.
• Wedge a block of wood between the blade and mower deck to prevent the blade from turning.
• For the BLADE I, loosen the blade nut by turning it clockwise (as viewed from bottom of
mower) using a 15 mm wrench or socket (not provided). For the BLADE II, loosen the blade
nut by turning it counterclockwise (as viewed from bottom of mower) using a 15 mm wrench or
socket (not provided).
• Remove the blade nut, spacer, blade insulator, and blade.
• Make certain the motor assembly is pushed completely against the motor shaft.
• Place the new blade on the shaft against the motor assembly. Ensure blade is properly
seated with shaft going through center blade hole and the two blade posts inserted into their
respective holes on the blade. Make sure it is installed with the curved ends pointing up
toward the mower deck and not down toward the ground. When seated properly, the blade
should be at against the motor assembly.

REPLACING THE BATTERY
The mower battery is designed for maximum life; however, like all batteries, it will eventually
need to be replaced.
Charge the new battery pack before use.
To install a new battery:

MAINTENANCE
CLEANING THE MOWER
W A R N I N G
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 forward
or on its side, and scrape it clean using an appropriate tool.
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).
• Lubricate the mower (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 2-3)
• Remove the battery and key, 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.
W A R N I N G
This battery must be charged when in storage to maintain running life.
29
SERVICE
• When servicing the mower, use only replacement parts that are available from the
manufacturer. In order to obtain replacement parts, call the toll-free helpline, at 1-888-909-
6757. The use of parts that do not meet the original equipment specifications 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.
Repair 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.
