TO INSTALL: Grinder must be mounted on hor-
izontal surface.
The Craftsman grinder pedestal is designed espe-
cially for your grinder. Use of the pedestal will
permit greater accessibility to your unit for grind-
ing, buffing, and many other uses.
To mount your grinder to the pedestal, align slots
in base with corresponding holes in table of the
pedestal. Use two 3/8" x 2" bolts (with flat wash-
ers beneath the heads) to secure the grinder.
Tighten nuts until space between grinder base and
pedestal is 3/16"as shown in drawing:

ILLUSTRATION FOR MOUNTING GRINDER
Using a second nut on each bolt, jam-tighten
against the first to prevent loosening by vibration.
A Craftsman workbench provides a good mount-
ing for your grinder, when drawer space is de-
sired as well as surface space.
Mount unit to bench top using two wood screws
through base grommets at front of grinder only.
Use two _" x 1_" round-head screws. Tighten
screws until clearance between base and surface
of bench is 3/16"(see illustration above).
15 ampere lighting circuit fuses should be satisfac-
tory. Otherwise, a "delayed-action" type fuse de-
signed to meet the demands of motor protection
and minimize possible nuisance of "blown" fuses
From momentary overloading.
The following wire sizes are recommended for ex-
tensions or special circuits.

Extension
15 feet or less
50 feet or less

.To start, move the toggle switch to "ON" posi-
tion. (Note: The lamp is also controlled by this
circuit.) If grinder does not start immediately,
disconnect power and check for lack of current
at power source. If, after verification of suffi-
cient power at source, the grinder will not start,
return it to point of purchase for inspection.
TO OPERATE:
BE SAFE! USE EYESHIELDS FURNISHED WITH
GRINDER AND WEAR RECOGNIZED EYE
PROTECTION. STAND AWAY FROM FRONT
OF GRINDER DURING FIRST MINUTE OF
OPERATION.
Before starting grinder, follow instructions in the
next two paragraphs concerning grounding, pro-
viding proper fuses and wire chart for electrical
extension wire sizes.
This grinder is equipped with a 3-conductor cord
having a fixed grounding conductor. Receptacle
not having provision for the grounding pin will re-
quire a plug adapter as shown in illustration below.
Protection of the operator may be insured by AL-
WAYS CONNECTING THE GROUND WIRE 1"O A
PERMANENT GROUND BEFORE PLUGGING IN
THE POWER LEADS. This connection can be rnade
to the receptacle cover screw, if the outlet box is
properly grounded, or to another suitable ground
such as a water pipe.

BE SURE BOX IS GROUNDED
If this grinder is not required to start under load
and is not overloaded after starting, the standard
.
.
The tool rests should be positioned securely to
support the material to be ground so that it
makes contact with the wheel slightly above
center-line of shaft at the desired angle.
Begin grinding by moving workpiece into con-
tact with the wheel gradually. Move from side
to side across the wheel evenly to remove ma-
terial more smoothly and help retain the
squareness of the wheel surface.
DO NOT FORCE WORK AGAINST GRIND-
ING WHEELS! EXCESSIVE PRESSURE MAY
CAUSE DAMAGE OR BREAKAGE.
Grinder should run near full speed for effec-
tive grinding and buffing.
TO MAINTAIN:
1. When vitrified wheels become irregular or
glazed from use they may be trued and
cleaned, returning them to near-new condition
with the cutting face fresh and square. Use a
Sears wheel dresser to keep your wheels in
good condition.
2. Clean out any accumulation of cuttings and
abrasive each time outer cover is removed.
.
Note: Wheel guards (Key No. 9) may be re-
moved for some adaptations of accessory
wheels without voiding the guarantee, how-
ever, disassembly of electrical connections or
end frames (10 & 18) by anyone other than
an authorized electric motor repair station will
void the guarantee.
Lubrication was provided at the factory for the
life of the ball bearings.

GUARANTEE
We will repair, at no cost, grinders that show de-
fects in materials or workmanship, if returned
within one year from the date of purchase.
