INSTALLATION
MOUNT GRINDER
•
Mount grinder to a solid horizontal surface (hardware not pro-
vided). If mounted to metal pedestal, align mounting holes
with corresponding holes in pedestal. Insert a
1
/
4
-20 x 1¼” hex
head bolt with flat washer through base of grinder. From bot-
tom of pedestal, place a
1
/
4
” flat washer and
1
/
4
”-20 hex nut onto
the bolt. Tighten only until space between grinder base and
pedestal is
1
/
8
” (base should be flush for 82101B). Using second
nut on each bolt, jam tighten against the first to prevent loos-
ening by vibration.
•
To mount grinder to wooden bench top, use
1
/
4
x 1¼” wood
screws with flat washers beneath heads. Tighten screws until
space between grinder base and bench top is
1
/
8
” (base should
be flush for 82101B).
GROUNDING INSTRUCTIONS
WARNING:
Improper connection of equipment grounding con-
ductor 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 grinder is equipped with an approved 3-conductor cord
rated at 300V and a 3-prong, grounding type plug (See Figure
2) for your protection against shock hazards.
•
Grounding plug should be plugged directly into a properly
installed and grounded 3- prong grounding-type receptacle
(See Figure 2).
•
Do not remove or alter grounding prong in any manner. In the
event of a malfunction or breakdown, grounding provides 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 nec-
essary, 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 3) is available for connecting plugs to a two pole outlet
if it is properly grounded.
•
Do not use a 3-prong to 2-prong grounding adapter unless
permitted by local and national codes and ordinances.
(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 per-
manent 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 voltage
and loss of power.
•
Wires of the extension cord must be of sufficient size to carry
the current and maintain adequate voltage.
•
Running the unit on voltages which are not within ±10% of the
specified voltage may cause overheating and motor burn-out.
•
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.

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, reconnected or
anytime wiring is inspected.
•
Motor and wires are installed as shown in wiring diagram (See
Figure 4, page 5). Motor is assembled with approved, 3-conduc-
tor cord to be used at 120/240 volts. Motor is prewired at the
factory for 120 volts.
•
To use the grinder with a 240V power supply, have a qualified
electrician rewire motor and attach a 240 volt, I5A three-prong
plug onto grinder line cord.
