Do not use a 3-prong to 2-prong grounding adapter unless permitted by local and national codes and
ordinances.
Installation (Continued)
(A 3-prong to 2-prong groundlng 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 property 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
1. The use of any extension cord will cause some drop in voltage and loss of power.
2. Wires of the extension cord must be of sufficient size to carry the current and maintain adequate
voltage.
3. Running the unit on voltages which are not within ±10% of the specified voltage may cause
overheating and motor burn-out.
4. Use the table to determine the mini- mum wire size (A.W.G.) extension cord.
5. Use only 3-wire extension cords hav- ing 3-prong grounding type plugs and 3-pole receptacles
which accept the tool plug.
6. If the extension cord is worn, cut or dam- aged in any way, ace it immediately.
EXTENSION CORD LENGTH FOR 2LKR9
Wire Slze A.W.G.
Up to 25 ft. 18.
NOTE:
Using extension cords over 25 ft. long is not recommended.
EXTENSION CORD LENGTH FOR MODEL MI-15450

ELECTRICAL CONNECTIONS
WARNING
All electrical connec-tions must be
per- formed 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). 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 grinder with a 230V power supply, have
a qualified electrician rewire motor and attach a
230 volt, 15A three-prong plug onto grinder line cord.

Operation
WARNING
Always wear safety glasses complying with United States ANSI 287.1 (shown on
package) before commencing powwer tool operation. Safety glasses are avail- able through
your Grainger catalog.
1. Keep a steady, moderate pressure on the work and keep it moving at an even pace for smooth
grinding.
2. Pressing too hard overheats the motor and prematurely wears down the grinding wheels.
