the safety precautions to reduce the risk of
fire, electric shock, and personal injury.
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.
RULES FOR SAFE OPERATION
•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 away 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.
SPECIAL SAFETY WARNINGS FOR ELECTRIC
POWERHEADS AND BLOWER/VACUUMS
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.
• Prevent disconnection of the blower/vacuum
powerhead from extension cord during operation by
using a plug-receptacle retaining strap, connector, or
by making a knot as shown below:
• 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 use in or around
water.
• 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
