The purpose of safety symbols is to attract your
attention to possible dangers. The safety symbols,
and their explanations, deserve your careful attention
and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions or
warnings they give are not substitutes for proper
accident prevention measures.
SYMBOL MEANING
SAFETY ALERT SYMBOL: Indicates
danger, warning, or caution. Attention is
required in order to avoid serious personal
injury. May be used in conjunction with
other symbols or pictographs.
NOTE: Advises you of information or instructions vital to
the operation or maintenance of the equipment.
DANGER: Failure to obey a safety warning
will result in serious injury to yourself or to
others. Always follow the safety precautions
to reduce the risk of fire, electric shock, and
personal injury.
WARNING: Failure to obey a safety warning

• IMPORTANT SAFETY INFORMATION •
• Move the unit at least 30 feet (9.1 m) from the fueling
source and site before starting the engine. Do not
smoke, keep sparks and open flames from the area
while adding fuel or operating the unit.
• Never start or run the unit inside a closed room or
building. Breathing exhaust fumes can kill. Operate
this unit only in a well ventilated area outdoors.
SAFETY WARNINGS FOR ELECTRIC TRIMMERS
AND LAWN EDGERS
• WARNING: To reduce the risk of electrical shock, use
only extension cords approved for outdoor use, such
as an extension cord of cord type SW-A, SOW-A,
STW-A, STOW-A, SJW-A, SJOW-A, SJTW-W or
SJTOW-A. Extension cords are available from your
local retailer. Use only round-jacketed extension cords
approved for outdoor use.
• CORD SETS: Make sure your cord set is in good
condition. When using a cord set, be sure to use a
cord that is heavy enough to carry the current that
your unit will draw.An undersized cord set will cause a
drop in line voltage resulting in loss of power and overheating. See the operator’s manual for the unit that will
power this add-on for the recommended cord size.
• Inspect all extension cords and the unit power
connection periodically. Look closely for deterioration,
cuts or cracks in the insulation. Also inspect the
connections for damage. Replace the cords if any
defects or damage appear.
• Avoid dangerous environments. Never operate your
unit in damp or wet conditions. Moisture is a shock
hazard.
• Do not use the unit in the rain.
• Do not handle the plug or unit with wet hands or
standing on any wet surfaces.
• Do not leave the unit plugged in when not in use,
changing attachments or add-ons, or while

HOLDING THE UNIT WITH EDGER ADD-ON
WARNING:
Always wear eye, hearing, foot
and body protection to reduce the risk of
injury when operating this unit.
Before operating the unit, stand in the operating position
(Figs. 4 & 5). Check for the following:
• The operator is wearing eye protection and proper
clothing.
• The right arm is slightly bent, and the hand is holding
the shaft grip.
• The left arm is straight, and the hand is holding the
handle.
• The unit is at waist level.
• The edger wheel adjusted for proper cut depth and
edger positioned as shown in Figs. 4 or 5.
ADJUSTING EDGER CUTTING DEPTH
1. Loosen the adjustment knob above the wheel
(Fig 6).
2. Slide the wheel to the desired position.
• Raising the wheel increases the cutting depth.
• Lowering the wheel decreases the cutting depth.
3. Tighten the adjustment knob securely.
TIPS FOR BEST EDGING RESULTS
• Keep the cutting attachment perpendicular to the
ground.
• Do not force the edger. Edge the first time at a lesser
depth, then do the area again with a deeper setting.
• Walk the edger at a slow, even pace
• Check the blade condition, as it wears it becomes
smaller, reducing the cutting depth performance.
Replace with a new blade as required.

EDGER BLADE REPLACEMENT
WARNING:
To avoid serious personal injury,
always wear gloves while handling, removing
or installing the blade.
WARNING: The gear housing gets hot
after long periods of use. To avoid serious
personal injury, do not touch the housing
until it has cooled.
1. Line up the hole in output shaft with the locking rod
slot. Insert the locking rod through the slot into the
output shaft hole (Fig. 7).
2. While holding the locking rod, loosen the nut on the
blade by turning it clockwise with a 5/8 inch wrench
(Fig. 8). Remove the nut, retaining washer and blade.
Keep the nut and blade retainer for installation.
3. Install the new blade, blade retainer, and nut
(Fig. 9). Insert the locking rod through the slot into
the output shaft hole. Make sure that the blade stays
flat and centered against the output shaft while
tightening the lock nut counterclockwise (Fig. 10).
4. If you have a torque wrench, tighten the nut to
325-335 in.•lbs (37-38 N•m), while holding the
locking rod in the slot.
If you do not have a torque wrench, hold the locking
rod in the slot. Rotate the nut
counterclockwise
with a 5/8 inch closed-ended or socket wrench, until
the nut presses against the washer and the blade is
snug. Make sure the blade assembly is installed
correctly, then rotate the nut an additional 1/4-1/2
turn (Fig. 10).
5. Remove the locking rod.
WARNING: Verify the blade is flat against
the output shaft after the nut is tightened. If
the blade is off-center, the unit will be
damaged by vibration, and the blade may fly
off, which can cause serious personal injury.
