SAFETY WARNINGS FOR GAS UNITS
• Store fuel only in containers specifically designed and approved
for the storage of such materials.
• Always stop the engine and allow it to cool before filling the
tank. Never remove the fuel tank cap or add fuel when the

instructions for later use.
WARNING:Gasoline is highly flammable and

precautions:
SAFETY WARNINGS FOR ELECTRIC UNITS
• 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 attachment 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 power head from the extension
cord during operation by using a plug-receptacle retaining strap,
connector, or by making a knot (Fig. A).
• 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
attachments or while being serviced.
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, STOWA, SJW-A, SJOW-A, SJTW-W or SJTOW-A. Extension
cords are available from your local retailer. Use only roundjacketed extension cords approved for outdoor use.
