repaired by authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean, and
free from oil and grease.
• DISCONNECT APPLIANCES. Disconnect the appliance from
the power supply when not in use, before servicing, and when
changing accessories such as blades and the like.
• AVOID UNINTENTIONAL STARTING. Don't carry plugged-
in appliance with finger on switch. Be sure switch is off when
plugging in.
• GROUND FAULT CIRCUIT INTERRUPTER (GFCI) protection
should be provided on the circuits or outlets to be used for the
gardening appliance. Receptacles are available having built in
GFCI protection and may be used for this measure of safety.
• STAY ALERT. Watch what you are doing. Use common sense.
Do not operate appliance when you are tired.
• CHECK DAMAGED PARTS. Before further use of the appliance,
a guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any other conditions that
may affect its operation. A guard or other part that is damaged
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this manual.
• USE OF ACCESSORIES AND ATTACHMENTS. The use of
any accessory or attachment not recommended for use with this
appliance could be hazardous. Note: Refer to the accessory
section of this manual for further details.
• EXTENSION CORDS. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An undersized
extension cord will cause a drop in line voltage resulting in loss of
power and overheating. The table below shows the correct size
to use depending on cord length and nameplate ampere rating.
If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord. To reduce the risk of disconnection
of the appliance from the extension cord during operation, use the
extension cord retainer described in this manual.

or the like. Do not use cutting line heavier than that recommended by
the manufacturer. See the accessory section of this manual for more
detailed information about the proper cutting line to use.
2. Keep the cutting line trimmed to the proper length (done automatically
by the appliance). Make sure that the guard is firmly in place, in
working order and positioned between yourself and the cutting line.
3. Wear long pants and substantial footwear to protect yourself from
injury caused by flying debris. This is especially important when
edging with the appliance.
