° Use _ x 1W' wood screws with flat washers beneath
heads.
• Tighten screws until base is flush with bench top.
POWER SOURCE
WARNING: Do not connect buffer to the power source until
all assembly steps have been completed.
The motor is designed for operation on the voltage and fre-
quency specified. Normal loads will be handled safely on volt-
ages not more than 10% above or below specified voltage.
Running the unit on voltages which are not within range may
cause overheating and motor burn-out. Heavy loads require
that voltage at motor terminals be no less than the voltage
specified on nameplate.
• Power supply to the motor is controlled by a single pole
locking rocker switch. Remove the key to prevent unautho-
rized use.
GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment grounding
conductor can result in the risk of electrical shock. Equipment
should be grounded while in use to protect operator from
electrical shock.
• Check with a qualified electrician if grounding instructions
are not understood or if in doubt as to whether the tool is
properly grounded.
• This tool is equipped with an approved 3-conductor cord
rated at 150V and a 3-prong grounding type plug (Figure 1)
for your protection against shock hazards.
• Grounding plug should be plugged directly into a properly
installed and grounded 3-prong grounding-type receptacle,
as shown (Figure 1).

• Do not remove or alter grounding prong in any manner. In
the event of a malfunction or breakdown, grounding pro-
vides a path of least resistance for electrical shock.
WARNING: Do not permit fingers to touch the terminals of
plug when installing or removing from outlet.
• Plug must be plugged into matching outlet that is properly
installed and grounded in accordance with all local codes and
ordinances. Do not modify plug provided. If it will not fit in out-
let, have proper outlet installed by a qualified electrician.
• Inspect tool cords periodically, and if damaged, have
repaired by an authorized service facility.
• Green (or green and yellow) conductor in cord is the
grounding wire. If repair or replacement of the electric cord
or plug is necessary, do not connect the green (or green
and yellow) wire to a live terminal.
• Where a 2-prong wall receptacle is encountered, it must be
replaced with a properly grounded 3-prong receptacle
installed in accordance with National Electric Code and
local codes and ordinances.
WARNING: This work should be performed by a qualified
electrician.
A temporary 3-prong to 2-prong grounding adapter (see
Figure 2) is available for connecting plugs to a two pole outlet
if it is properly grounded.

(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.

DESCRIPTION
Craftsman 6" and 8" Buffers are equipped with totally
enclosed 1/2HP 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.
