Black & Decker 4011 - Manual (Page 4)

Tools built with this insulation
system are not intended to be grounded.
As a result, your Sander is equipped with
a two-prong plug which permits you to
use extension cords without concern for
maintaining a ground connection.
NOTE: DOUBLE-INSULATION
does not take the place of normal safety
precautions when operating this tool. The
insulation system is for added protection
against injury resulting from a possible
electrical insulation failure within the tool.
CAUTION: When servicing Double
Insulated Tools. USE ONLY IDENTICAL
REPLACEMENT PARTS. Repair or
replace damaged cords.
Special Safety
Instructions For Sanders
Always wear eye protection and a
respirator when sanding.
See page 8 for special caution
concerning the removal of lead based
paint.
Double Insulation
Your Sander is DOUBLE-INSU­
LATED to give you added safety. This
means that it is constructed throughout
with TWO separate “layers” of electrical
insulation or one DOUBLE thickness of
insulation between you and the tool’s
electrical system.
Extension Cords
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. The letters “WA” on the cord
jacket indicate that the cord is suitable for outdoor use.
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.
To determine the minimum wire size required, refer to the chart below:

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. Black & Decker has extension cords available that are U.L. (C.S.A. in
Canada) listed for outdoor use.
Tool Care
Keep your machine as clean as
possible by wiping with a clean cloth and
occasionally blowing through with air.
Don't use harsh chemicals or
solvents to clean the tool. These
chemicals could seriously damage the
plastic.
Avoid overloading your sander.
Overloading will result in a considerable
reduction in speed and efficiency and the
unit will become hot. In this event, run
sander at a “no load” condition for a
minute or two.
Brush Replacement
TURN OFF AND UNPLUG THE
SANDER
To replace the tool's brushes, remove
the three screws located in the top cap,
as shown in Figure 9. Lift off the top
cap. Observe the brush holders, as
shown in Figure 10 and the wires
leading from the brushes to the motor
field.
Pull the wires from iriu motor field and
then lift and hold oul of the way one of
the brush springs. Remove the old brush
from the brush holder and discard the
brush/wire assembly. Slil! holding the
brush spring out of
the way, insert the
new brush, release the spring against
the back of the brush and plug the wire
into the motor field. Repeat the proce­
dure for the second brush.
Replace the top cap and tighten the
three screws that hold it in place.
(Always replace both brushes.)
