Servicing Of Double Insulated Appliances - Black & Decker BV2900 Instruction Manual

WARNING:

reduce the risk of electrical shock; do not expose to
rain, do not use on wet surfaces. Store indoors.
 WARNING:
unplug unit, then wait until fan stops or at least 10 seconds
before removing the blower or vacuum tube assemblies.

Servicing of Double Insulated Appliances

Your Blower/Vac is double-insulated to give you added safety.
In a double insulated appliance, two systems of insulation
are provided instead of grounding. No grounding means is
provided on a double insulated appliance, nor should a means
for grounding be added to the appliance. Servicing a double
insulated appliance requires extreme care and knowledge
of the system and should be done only by qualified service
personnel. Replacement parts for a double insulated appliance
must be identical to the parts they replace. A double insulated
appliance is marked with the words double insulated or
"double insulation". The symbol (square within a square) may
also be marked on the appliance.

Safety Rules and Instructions:
Extension Cords
 WARNING:
injury due to a loose electrical connection between the
appliance's plug and extension cord, firmly and fully attach
the appliance plug to the extension cord. Periodically check
the connection while operating to ensure it is fully attached.
Do not use an extension cord that provides a loose
connection. A loose connection may result in overheating,
fire, and increases the risk of a burning.
Double insulated tools have 2-wire cords and can be used with
2-wire or 3-wire extension cords. Only round jacketed extension
cords should be used, and we recommend that they be listed by
Underwriters Laboratories (U.L.) (C.S.A. in Canada). If the extension
will be used outside, the cord must be suitable for outdoor
use. Any cord marked as outdoor can also be used for indoor
work. An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety, and to prevent loss of power and
overheating. The smaller the gauge number of the wire, the greater
the capacity of the cable, that is 16 gauge has more capacity than
18 gauge. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. Before using an extension cord, inspect it for
loose or exposed wires, damaged insulation, and defective fittings.
Make any needed repairs or replace the cord if necessary.
• To reduce the risk of disconnection of the appliance cord
from the extension cord during operating:
i) Make a knot as shown in figure B, or
ii) Use one of the plug-receptacle retaining straps or
connectors described in this manual. (The manual
shall also include a statement indicating that devices
for retaining extension cords are available. The name
and address of the manufacturer or brand-name
distributor shall be included.); or

iii) Secure the extension cord to the appliance plug as
shown or described in the Operating Instructions.
• Maintain Appliance With Care – Inspect extension cords
periodically and replace if damaged.

Safety Rules and Instructions:
Polarized Plug
To reduce the risk of electric shock, this equipment has a polarized
plug (one blade is wider than the other). This equipment must
be used with a suitable polarized 2 wire or 3 wire extension cord.
Polarized connections will fit together only one way. Make sure
that the receptacle end of the extension cord has large and small
blade slot widths. If the plug does not fit fully into the extension
cord, reverse the plug. If it still does not fit, obtain a suitable
extension cord. If the extension cord does not fit fully into the
outlet, contact a qualified electrician to install the proper outlet.
Do not change the tool plug or extension cord in any way.
