(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on
the side of the adapter must be securely connected to a
permanent electrical ground such as a properly grounded
water pipe, a properly grounded outlet box or a properly
grounded wire system.
• Many cover plate screws, water pipes and outlet boxes are
not properly grounded. To ensure proper ground, grounding
means must be tested by a qualified electrician.
EXTENSION CORDS
• The use of any extension cord will cause some drop in volt-
age and loss of power.
• Wires of the extension cord must be of sufficient size to
carry the current and maintain adequate voltage.
• Use the table to determine the minimum wire size (A.W.G.)
extension cord.
• Use only 3-wire extension cords having 3-prong grounding
type plugs and 3-pole receptacles which accept the tool
plug.
• If the extension cord is worn, cut, or damaged in any way,
replace it immediately.
Extension Cord Length
Wire Size ................................... A.W.G.
Up to 25 ft....................................... 18
25 to 50 ft ....................................... 16
NOTE: Using extension cords over 50 ft. long is not
recommended.
ELECTRICAL CONNECTIONS
WARNING: All electrical connections must be performed by
a qualified electrician. Make sure tool is off and disconnected
from power source while motor is mounted, connected, recon-
nected or anytime wiring is inspected.
REWIRING 8" BUFFER (MODEL 211812)
Motor and wires are installed as shown in wiring diagram
(See Figure 3). Motor is assembled with approved, 3-conduc-
tor cord to be used at 115/230 volts. Motor is prewired at the
factory for 115 volts.
To use the buffer with a 240V power supply, have a qualified
electrician rewire motor and attach a 240 volt, 15A three-prong
plug onto buffer line cord.

DESCRIPTION
Craftsman 6" and 8" Buffers are equipped with totally
enclosed 1/2 HP and 3/4HP motors, respectively. The 6" Buffer
is equipped with a single voltage motor and 8" Buffer is
equipped with a dual voltage motor. Armature assembly is
dynamically balanced for smooth operation. Motor housing is
compact so long pieces of work can press against both
wheels without touching the motor frame.
WARNING: Always wear safety glasses complying with
United States ANSI Z87.1 before commencing power tool
operation. Safety glasses are available through your Sears
catalog.
• Load buffing compound, appropriate for your workpiece,
onto the wheel.
• Carefully guide workpiece into wheel.
• Keep a steady, moderate pressure on the work piece and
keep it moving at an even pace for smooth buffing.
• Pressing too hard overheats the motor and prematurely
wears down the buffing wheels.
• The buffing wheel should rotate into object being polished.
