SLOPE OPERATION
• Slopes are a major factor related to slip and fall accidents that can result in severe injury. Operation
on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For your safety, do
not attempt to mow slopes greater than 15o.
• Mow across the face of slopes, not up and down. Exercise extreme caution when changing
direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall
grass can hide obstacles. Remove all objects such as rocks, tree limbs, etc., which could be
tripped over or thrown by the blade.
• Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are
losing your balance, release the switch control lever immediately.
• Do not mow near drop-offs, ditches, or embankments; you could lose your footing or balance.
! WARNING: Do not mow a slope that has an angle of greater
than 15° (a rise of approximately 2-1/2’ [75 cm] every 10’ [3 m]).
Mow across the face of a slope, and never up and down.

!
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 a year, as described in the Maintenance section.
! 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.
!
NOTE: ALWAYS INSPECT AREA WHERE MOWER IS TO BE USED
AND REMOVE ALL STONES, STICKS, WIRE, BONES AND OTHER
DEBRIS WHICH MIGHT BE THROWN BY THE ROTATING BLADE.
MOWING TIPS
• 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 lawn height should be approximately 1-1/2 to 2” (3.8 to 5 cm) during
cooler months, and 2-3 3/4” (5 to 8.9 cm) long during hottor months. If there is growth, the lawn
should be cut in the fall.
MULCHING TIPS
• Release switch to turn mower OFF when crossing any graveled area (stones can be thrown by the
blade).
• Set mower at highest cutting height when mowing on rough ground or in tall weeds.
• For effective mulching, do not cut wet grass, as 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 in excess of 4”, mow twice to reduce the grass height to
3 3/4” maximum.
• Walk at a good, steady pace. Overlap your rows. Don’t 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.

REPLACING THE CUTTING BLADE
Use only a YARDWORKS replacement blade.
1. REMOVE BATTERY.
2. 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.
3. Using a 15 mm wrench or socket, loosen the blade nut (1) and remove the blade (4). Turn the nut
COUNTER-CLOCKWISE to loosen it and CLOCKWISE to tighten it.
4. Remove the blade nut (1), the square washer (2), the insulator washer (3), and the blade.
5. To re-install the blade, position the blade with the cutting edges toward the ground. Assemble
the blade nut, the square washer, and the insulator washer as shown. Using a 15 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 4 of this manual.
!
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
isolator key when servicing or transporting the mower.

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. See Battery & Charger section of this manual.
TO INSTALL A NEW BATTERY:
1. Remove the isolator key.
2. Carefully lift the old battery by the handle.
3. Install the new battery pack.
4. Take the old battery pack to a recycling centre that accepts lead acid/lithium ion batteries. Never
dispose of battery in re or regular household trash.
CLEANING THE MOWER
The underside of mower deck should be cleaned after each use as grass clippings, leaves, dirt and
other debris will accumulate, causing rust and corrosion.
• Remove any buildup of grass and leaves on or around the motor cover (do not use water). Occa-
sionally wipe the mower clean with a dry cloth.
• If debris build up on the underside of the unit while in use, stop the motor and remove the battery.
Tilt the mower forward or on its side, and scrape it clean with an appropriate tool.
! WARNING: To reduce the risk of electric shock, do not
expose the mower to water.

STORING THE MOWER
The following steps should be taken in order to prepare the lawn mower for storage.
1. Clean the mower as described in the previous section.
2. Inspect the blade, and replace it or sharpen it, if required (refer to the Maintenance section).
3. Lubricate the mower (refer to the Maintenance section).
4. Store the mower in a dry, clean location. Do not store it next to corrosive materials, such as
fertilizer or rock salt.
5. 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.
6. 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 extend its life.
7. Remove the key and store in a secure location out of the reach of children. Removal of the battery
