SPECIFIC RULES FOR THE BENCH GRINDER
11. USE ONLY GRINDING WHEELS that comply with ANSI B7.1 and are rated greater than 3550 RPM.
12. GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces. For ex-
ample: pipes, radiators, ranges, refrigerator enclosures.
13. DO NOT use wheels with incorrect size holes. NEVER use wheel washers or wheel screws that are defective or
incorrect, and NEVER touch a grinding wheel or other moving parts.
14. NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the grinding path of
the wheel.
15. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your
hand to move into the wheel. ALWAYS make sure you have good balance.
16. NEVER stand or have any part of your body in line with the path of the wheel.
17. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches re-
placed by an authorized service center.
18. DO NOT TURN THE MOTOR SWITCH ON AND OFF RAPIDLY. This could cause the wheel to loosen
and create a hazard. Should this ever occur, stand clear and allow the wheel to come to a complete stop. Disconnect
your grinder from the power supply and retighten the wheel nut securely.
19. RISK OF INJURY DUE TO ACCIDENTAL STARTING. Do not use in an area where children may be
present.
20. NEVER START THE GRINDER when the wheel is in contact with the workpiece.
21. SECURE WORK. Always hold the workpiece firmly against the work rest.
22. DO NOT USE THE BENCH GRINDER if the flange nut or clamp nut is missing or if the spindle shaft is bent.
23. FREQUENTLY clean grinding dust from beneath the grinder.
24. ALWAYS EASE THE WORKPIECE AGAINST THE ABRASIVE WHEEL when starting to grind. A harsh
impact can break the wheel. Use light pressure when starting to grind. Too much pressure on a cold wheel can cause
the wheel to crack.
25. USE ONLY FLANGES furnished with this bench grinder.
26. IF ANY PART OF THIS GRINDER IS MISSING, broken, bent, or damaged in any way, or if any electrical
component fails to perform properly, shut off the power switch, remove the machine plug from the power source
and have the damaged, missing, or failed parts replaced before operation.
27. 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, balance the blade by removing
additional material.
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an electric current and reduces the risk of electric shock. 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 local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conduc-
tor 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 licensed electrician or service personnel if you do not completely understand the grounding instruc-
tions or whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets that accept the
tool’s plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a li-
censed electrician check the outlet.
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
EXTENSION CORD GUIDELINES
Make sure your extension cord is in good condition. 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 a drop in line voltage resulting
in loss of power and overheating. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than
a #12 wire and should be protected with a 15 A time-delayed fuse. Before con-
necting the motor to the power line, make sure the switch is in the OFF position
and the electric current is rated the same as the current stamped on the motor
nameplate. Running at a lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator
from electric shock.

ASSEMBLY
TOOL RESTS
Two different tool rests are included with this
bench grinder. To install these tool rests:
1. Attach the tool rest support (Fig. A - 1) to the
inside surface of the wheel cover using a flat washer
(Fig. A - 2) and a hex head screw (Fig. A - 3).
2. Attach the tool rest (Fig. A - 4) to the tool rest
support (Fig A - 1) using a flat washer (Fig. A - 5)
and an adjustment knob (Fig. A - 6).
3. Adjust each tool rest until its inside edge is 1/16
of an inch from the grinding wheel. Tighten the
hex head screws holding the supports in place.
4. If you are wanting to sharpen drill bits, there
is also a drill bit sharpening plate included in this
package. Attach it to the tool rest support in the
same way as you would the regular tool rests. The
divot running diagonally down the center of the
tool rests allows for easy sharpening of the tips of
bits. Only use this plate for sharpening drill bits.
SPARK ARRESTORS AND EYE SHIELDS
1. Attach the spark arrestors (Fig. B - 1) to the
inside surface of the wheel covers using two screws
and washers (Fig. B - 2).
2. Position said spark arrestors so that the lower
edge is 1/16 of an inch from the grinding wheel.
Firmly tighten the hex head screws.
3. Attach the eye shields (Fig. B - 3) to the spark ar-
restor by inserting a carriage head screw (Fig. B - 4)
through the eye shield and the spark arrestor.
4. Position the eye shield into its desired position.
Assemble the flat washer (Fig. B - 5) and lock knob
(Fig. B - 6) to the carriage head screw and tighten
until the eye shield no longer moves.

WORKLIGHT
The bench grinder provided has a flexible work light to maximize visibility during operation. A light bulb for the
flexible work light is not included. Use a 120 Volt, 40 watt or less track light bult (type R20, medium base) for the
onboard lamp. Make sure the bulb does not protrude past the rim of the light’s housing.
The flexible work light can be positioned in whatever direction you choose. Using the switch located on the top of
the housing will turn the light on and off.
WARNING: The light’s housing will remain hot for a few minutes after operation. Make sure to not touch either
the bulb or the housing during or directly after use.
PERMANENT MOUNTING
Firmly attach the grinder to a reliable work surface using the mounting pads and the included holes along the base
of the grinder (mounting hardware not included). This will prevent the possibility of vibration, walking or tipping
during operation.
WARNING: Do not operate this machine without first attaching the base to a reliable surface.
ASSEMBLY
OPERATION
1. Turn the variable speed knob to its lowest setting before turning on the bench grinder.
2. To operate the bench grinder, always wear safety glasses and turn the tool on while standing to the side of the
grinder (as opposed to in front). Allow it to reach full speed before grinding.
3. Once the grinder is up and running, set the grinder to your desired speed. The lowest speed setting should be
used for light grinding, sharpening, and paint/rust removal. The highest speed should be used for deburring, mate-
rial removal and other heavier grinding tasks.
4. Hold the work piece firmly against the tool rest. Hold very small pieces with pliers or other suitable clamps.
5. Feed the work piece smoothly and evenly into the grinding wheel. Move it back and forth as to not burn any one
area of the surface and also to make for even grinding.
6. Move the work piece slowly and avoid jamming the work piece against the wheel. If the wheel tends to slow down
from excessive force, you should occasionally release the pressure to let the wheel return to full speed.
7. Grind only on the face of the grinding wheel; never the side of it
8. Place the hot end of the workpiece into the quenching tray to cool it off if you so choose.
9. Once grinding operations are complete, return the variable speed knob to its lowest setting. Once the wheels
have reached their new low speed, turn the bench grinder off and unplug it. Avoid contact with the bench grinder’s
housing until it has cooled down completely.

MAINTENANCE
WARNING: For your own safety, turn the switch OFF and remove the plug from the electrical outlet before
adjusting or performing maintenance or lubrication work on the sharpener.
Before using, check to make sure parts are not damaged, missing, or worn. Check for alignment of moving parts,
binding of moving parts, improper mounting, or any other conditions that may affect the sharpener’s operation. If
any of these conditions exist, do not use until parts are replaced or the sharpener is properly repaired. Frequently
blow or vacuum dust from all surfaces and the motor housing.
WARNING: Any attempt to repair or replace electrical parts on this tool may be hazardous. Repairs should be
done by a qualified service technician only.
1. Regularly check the tool and use a soft brush to remove accumulated dust. Wear safety goggles to protect your
eyes while cleaning.
2. If the body of the grinder needs cleaning, wipe it down with a soft, damp cloth. A mild detergent can be used.
Do not use alcohol, petrol or other similar cleaning agents. Do not make contact with the grinding wheels with any
damp cloth.
3. Always make sure the eye shields are transparent and not blocking the view of the grinding wheel.
SHARPENING GUIDE:
SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer. Remove material only from
the outside surface and work from the heavy end of the blade toward the tip.
KNIVES
Remove metal from both faces of most knives, working from the heavy end of the blade toward the tip.
SCREWDRIVERS
The end of a properly sharpened screwdriver will be a perfectly flat rectangle, perpendicular to the center line of the
shank. The two sides and two faces will taper outward from the edge of the shoulder or shank. They should be flat
with perpendicular intersecting faces. Hold each face of the screwdriver against the wheel to true it up, then ease the
end straight into the stone to grind it true.
LAWN MOWER BLADES
Lawn mower blades are usually sharpened on only one side and dressed up slightly on the other. After sharpening,
be sure to balance the blade by removing additional material from the heavy end. There are a number of inexpen-
sive cone balancers on the market for this purpose. Unbalanced blades can cause serious crank shaft damage to
your lawn mower. Always remove spark plug wires or battery from the mower before servicing the blades to prevent
accidental startups.
DRILL BITS
Use the drill bit tool rest to provide angled support to drill bits during grinding operation. The angled divot running
through the rest allows for a cradle for drill bits during sharpening operations.
