Installation (Continued)

(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

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.

ELECTRICAL CONNECTIONS

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 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.

Operation

Always wear safety

glasses complying

with United States ANSI Z87.1 (shown

on package) before commencing power

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.

3. Note the original bevel angle on the

item to be sharpened and try to

maintain that angle. Sharpening a

cutting edge requires removing burrs

from edge.

4. Deburring edge is done best by using

the grinder to pull burr from edge

across the bevel angle.

5. The grinding wheel should rotate

into object being sharpened.

6. Dip work into a coolant regularly to

prevent overheating. Overheating

can weaken metals.

Maintenance

1. As wheels wear, tool rests should be

positioned closer to the face of the

wheels.

2. The gap between the wheel and the

tool rest should not be greater than

1/16”. When the wheels are worn to

the extent that the 1/16” maximum

gap cannot be maintained, the

wheels should beaced.

3. Models 2LKR8 and 2LKR9:acement

wheels should have a minimum rated

speed of at least 3600 RPM.

Model 2LKT2:acement wheels must

have a minimum rated speed of 1800

RPM.

4. Maximum wheel diameter is 7” for

2LKR8, 8” for 2LKR9 and 10” for

2LKT2.
