ELECTRICAL
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the product’s plug.
When using a power tool at a considerable distance from
the power source, use an extension cord heavy enough to
carry the current that the product will draw. An undersized
extension cord will cause a drop in line voltage, resulting in
a loss of power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire size
required in an extension cord. Only round jacketed cords
listed by Underwriter’s Laboratories (UL) should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the product outdoors, use an extension
cord that is designed for outside use. This is indicated by the
letters “W-A” or “W” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with a
power tool. Failure to do so can result in serious personal
injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use the product with a
damaged cord since touching the damaged area could
cause electrical shock resulting in serious injury.
ELECTRICAL CONNECTION
This product is powered by a precision-built electric motor. It
should be connected to a power supply that is 120 V, AC only
(normal household current), 60 Hz. Do not operate this
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double check the power supply.
SPEED AND WIRING
The no-load speed of this product is approximately 3,600
rpm. This speed is not constant and decreases under a
load or with lower voltage. For voltage, the wiring in a
shop is as important as the motor’s horsepower rating. A
line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance
will be too light for a greater distance. A line that can
support one power tool may not be able to support two
or three products.
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of a malfunction
or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock.
This product is equipped with an electric cord having 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 local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper connection of the grounding plug can result in a
risk of electric shock. When repair or replacement of the
cord is required, do not connect the grounding wire to
either flat blade terminal. The wire with insulation having
an outer surface that is green with or without yellow
stripes is the grounding wire.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely understood,
or if in doubt as to whether the product is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120 V circuit and has
a grounding plug similar to the plug illustrated in figure 1,
page 13. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter with
this product.

SHARPENING TWIST DRILL BITS
See Figure 9, page 15.
Drill bits are best sharpened on a sharpening jig (available at
most hardware stores). Begin on one side of the point at the
existing angle, then twist the bit while maintaining contact
with the grinding surface. Sharpen only the tip.
This technique requires considerable practice, so take your
time and make a few “dry runs” first with the grinder off. Be
sure to maintain the original cutting edge angle as this is
important to the efficiency of your bits.
CAUTION:
Never sharpen or grind anything made of aluminum,
brass, or copper.
WARNING:
Do not use wheels rated less than the speed of this tool.
Failure to heed this warning could result in personal injury.
APPLICATIONS
This product has been designed only for the purposes listed
below:
Sharpening drill bits
Sharpening lawn mower blades
Sharpening chisels and flat screwdrivers
BASIC OPERATION
To be efficient and work as designed, your tools should be
kept sharp. Dull tools can and will cause accidents.
Bench Grinders are ideal for sharpening tools such as chisels, planer blades, scissors, etc., and for removing rust or
corrosion. Grinders remove material rapidly so pressure is
the key to efficient grinding.
SHARPENING LAWN MOWER BLADES
See Figure 10, page 15.
Lawn mower blades are usually sharpened on only one edge
and dressed up slightly on the other. Perform this sharpening
process on both cutting ends of the blade. After sharpening,
be sure to balance the blade by removing additional material.
CAUTION:
An unbalanced lawn mower blade may cause excessive
vibration which will damage the lawn mower.
SHARPENING CHISELS AND SCREWDRIVER
BLADES
See Figure 11, page 15.
When sharpening chisels and screwdrivers, work rest should
support the chisel at the correct angle against the wheel.
