Before You Start – Electrical
In the event of a malfunction or short circuit, grounding provides the path of least resistance for electrical
current, and reduces the risk of electric shock for the operator. This tool is equipped with an electric cord
that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a
matching outlet that is properly installed and grounded in accordance with ALL
ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by an
electrician.

IMPROPER CONNECTION of the equipment grounding conductor can result in increased risk of electric
shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding
conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT connect the
equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service personnel if you do not completely understand the
grounding instructions, or if you are not

Use of Extension Cords
USE ONLY THREE-WIRED EXTENSION CORDS that have 3-pronged plugs and 3-holed outlets that
accept the tool’s plug. Repair or replace damaged or worn cords immediately.
Be sure your extension cord is properly wired and in good condition. Do not use damaged extension
cords. Always replace a damaged extension cord.
When using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause
table below shows the correct size to use according to the cord length and the amperage draw of the tool
(specified on the nameplate). When in doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord. (AWG = American Wire Gauge).
Use a separate electrical circuit for your tools. This circuit should not be less than a #12 gauge wire, and
should be protected with a 15 A time-lag fuse. Before connecting the motor to the power line, ensure the
switch is in the OFF position and the electric current is rated the same as the current stamped on the
motor’s nameplate. Running at a lower voltage will damage the motor and is not covered by warranty.

Using Your Bench Grinder
This 8” Bench Grinder is ideal for use in sharpening chisels, axes and other wood-cutting tools. It is also
useful for repairing tips on screwdrivers and drill bits or for removing excess metal burrs from pieces of
cut metal.
With the proper accessories, this tool can be used for cleaning metal surfaces using a wire brush or for
buffing and polishing using a cloth wheel.
ON/OFF
The rocker ON/OFF power switch is located on the front of the grinder.
1. Press the side marked ON to turn the grinder on.
2. Press the side marked OFF to turn the grinder off.
Grinding
Adjust the tool rest to accommodate large or unusually shaped workpieces.
Always keep the workpiece moving across the face of the grinding wheel. Grinding continuously
on the same spot on the wheel will cause grooves to be worn into the wheel. The wheel may
crack or become damaged more easily, and grinding of other objects will be difficult.
If the workpiece becomes hot, dip it into the water or oil to cool it.
Always grind on the face of the wheel (around the diameter), NEVER on the sides. Side pressure
on grinding wheels can cause cracking and damage.
10
If the face of the grinding wheel is worn unevenly, becomes grooved, or is no longer smooth and
flat, the wheel should be reshaped with a dressing tool (not supplied).
If the diameter of the grinding wheel is no longer round, the wheel should be reshaped with a
dressing tool or replaced.
If the surface of the wheel becomes loaded and dull with workpiece material, the wheel should be
cleaned with a dressing tool.
After reshaping, always readjust the tool rests and spark arrestors.
