SAFETY WARNINGS
4
• Thoroughly inspect the trimmer for loose or
damaged parts before each use. Do not use
until adjustments or repairs are made.
• All guards and safety attachments must be
installed properly before operating the unit.
• Use the unit only in daylight or good artificial
light.
• Keep all bystanders, especially children and
pets, at least 30 feet (9.2 m) away from the
unit during operation.
• Before starting, adjust the handle to your size
and make sure that the cutting head is not in
contact with anything.
• Be aware of the risk of injury to the head,
hands and feet.
• Carefully inspect the areas to be cut. Remove
all debris that could become entangled in the
string or blade. Also remove any objects that
could be thrown during cutting.
WHILE OPERATING
• Use the right tool. Do not use this trimmer for
any job except that for which it is intended.
• Avoid accidental starting. Do not carry
plugged-in unit with your finger on the
switch. Be sure switch is off when
plugging in.
• Do not abuse the power cord. Never carry
the unit by the cord or yank the plug out of
the receptacle. Keep the cord away from
heat, oil and sharp edges.
• Always remain alert. To prevent injury to
yourself and others, do not operate this
trimmer if you are fatigued.
• Do not operate the unit while under the
influence of drugs, alcohol or medication.
• Wear safety glasses or goggles at all times
when operating this trimmer.
• Use a face mask or dust mask if operation is
dusty.
• Do not overreach. Keep proper footing and
balance at all times.
• Dress properly. Do not operate this trimmer
when barefoot or wearing open sandals.
Always wear sturdy, rubber-soled footwear.
The use of gloves, ear/hearing protection
and long pants are recommended.
• A nameplate on your unit indicates what
voltage it uses. Never connect the unit to an
AC voltage that differs from this voltage.
• 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. Repair or replace the cords if any
defects 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 the unit with wet
hands.
BEFORE OPERATING
• Read the instructions carefully. Be familiar
with the controls and proper use of the unit.
• Children and adolescents must not
manipulate units, except for adolescents in
training and under the supervision of a
specialist.
• Before each use, check that the cutting head
is correctly fixed and that the trigger returns
automatically in neutral position.
• 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. The table shows the correct size
to use depending on the cord length and
nameplate amperage rating. If in doubt, use
the next heavier size line gauge. The smaller
the gauge number, the heavier the cord. To
reduce the possibility of disconnection of the
unit cord from the cord set during operation,
see Fig. 9.
