3. In order to avoid contact with the blade or injury caused by a thrown object, stay in the
operating zone behind the handles, and keep children and bystanders at least 100' (30 m)
away from the mower while it is in operation. Stop the motor immediately if someone enters
the mowing area.
4. Thoroughly inspect the area where the mower is to be used. Remove all stones, sticks, wire,
bones, toys, and other objects that could be tripped over or thrown by the blade. Thrown
objects can cause serious personal injury.
5. Plan your mowing pattern in such a way as to avoid discharging material toward roads,
sidewalks, bystanders, etc. Do not discharge material against a wall or obstruction. Doing so
may cause the discharged material to ricochet back toward the operator.
6. Always wear proper eye protection in order to protect your eyes while operating or performing
any adjustment or repair. Thrown objects that ricochet can cause serious eye injury.

SAFE OPERATION

7. Always wear a face mask or a dust mask when operating the mower in a dusty environment.
8. Dress properly. Do not wear loose clothing or jewellery that can get caught in moving parts.
The wearing of protective gloves and safety footwear is recommended.
9. Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or
outlet(s) that will be used to charge the lawn mower battery. Outlets with built-in GFCI
protection are available, and may be used as an added safety measure.
10. Many injuries occur as a result of the mower being pulled over the operator's foot during a fall
caused by slipping or tripping. Do not operate this mower in bare feet, or while wearing
sandals or lightweight (e.g.: canvas) shoes. Do not hold on to the mower if you are falling.
Release the handle immediately.
11. Never pull the mower back toward you while you are walking. If you must back the mower
away from a wall or an obstruction, first look down and behind in order to avoid tripping, and
then follow these steps:
• Step back from the mower in order to fully extend your arms.
• Be sure that you are well balanced.
• Pull the mower back slowly.
12. Do not use the mower for any job except that for which it is intended. Do not force the mower.
13. Do not operate the mower while under the influence of alcohol or drugs.
14. Stay Alert: Do not operate the mower when you are tired. Pay attention to what you are doing.
Use common sense.
15. Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade
can amputate hands and feet.
16. Do not attempt to adjust the wheels or the cutting height while the motor is running.
17. Avoid dangerous environments. Do not operate the mower in the rain or in wet or damp grass.
18. Mow only in daylight or in good artificial light. Do not rush a mowing job.
19. Stop the blade when crossing gravel driveways, walkways, or roads.
20. If the mower starts to vibrate excessively, stop the motor and check for the cause immediately.
Vibration is generally a warning of trouble.
21. Stop the motor and wait until the blade comes to a complete stop before removing the grass
catcher or unclogging the chute. The cutting blade will continue to rotate for a few seconds
after the motor is shut off. Do not place any part of your body in the blade area until you are
sure that the blade has stopped rotating.
22. Never operate mower without a proper trail shield, discharge cover, grass catcher, switch
control, or other safety device in place and in working order. Do not operate the mower with
damaged safety devices. Doing so can result in injury.

SLOPE GAUGE & OPERATION
18
1. Mow across the face of a slope, and never up and down. Exercise extreme caution when
changing direction on a slope.
2. Watch for holes, ruts, rocks, hidden objects, or bumps that may cause a slip or a trip. Tall grass
can hide obstacles.
3. 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.
4. Do not mow near drop-offs, ditches, or embankments, because you could lose your footing or
balance.
5. Do not mow a slope that has an angle of greater than 15°, as determined using the slope
gauge.
6. Do not mow wet or damp grass. Unstable footing can cause slipping.
Use this page as a guide in order to identify slopes that cannot be mowed safely.
WARNING: 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.
WARNING: 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.
SLOPE GAUGE

SLOPE GAUGE & OPERATION
19
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.
1. 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.
2. Do not mow in circles. Travel back and forth across the lawn.
3. When cutting thick grass, reduce walking speed in order to allow for a more effective cut and a
proper discharge of the clippings.
4. 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 more than
2” (5 cm) long during hot months. If there is growth, the lawn should be cut in the fall.
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.
1. Release the switch to turn the mower OFF when crossing any graveled area (stones can be
thrown by the blade).
2. Set mower to the highest cutting height when mowing on uneven ground or in tall weeds.
3. 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).
4. 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.
MOWING TIPS
MULCHING TIPS

MAINTENANCE
20
Use only a YARDWORKS replacement blade (xx-xxxx-x).
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 26 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 fuse key when servicing or transporting the mower.
