WARNING: Do not plug in or operate this tool until the entire manual has
been read and understood.Failure to do so may result in personal injury or
machine damage.
1. Use only the correct grinding wheels that meet the following requirements:
• The speed rating of the wheel is greater than 3450 RPM.
• The wheel complies with ANSI B7.1.
• The size of the wheel is 6 inches in diameter and 3/4 inch thick with a 1/2-inch arbor.
Do not use wheels with incorrect arbor size.
2. Always inspect grinding wheels prior to use for cracks or missing pieces. If imperfec-
tions are present, replace wheel immediately before use. Never use wheel washers
or screws that are defective or incorrect.
3. Thoroughly inspect the grinder. Do not use the bench grinder if the flange nut or arbor
hex nut is missing or if the spindle shaft is bent. Use only flanges furnished with this
bench grinder.
4. Never touch a grinding wheel or other moving parts during operation or immediately
after use. It takes approximately 3 minutes for the wheels to come to a stop after the
tool is switched off.
5. Do not overtighten the wheel nut. Do not use an impact wrench to make adjustments
to the grinding wheel nuts,as it could cause damage to the wheel, which could cause
severe injury.
6. Risk of injury due to accidental starting. Do not use in an area where children may be
present.
7. Always secure the bench grinder by bolting it down to its supporting surface to prevent
the grinder from tipping over, sliding, or walking during operation.
8. Do not remove the wheel guard, unless changing a grinding wheel. Ensure the cover
is replaced before using the grinder. Always use the guards, spark deflectors and eye
shields during operation.
9. Check the ON/OFF switch of your tool. Do not use tool if switch does not turn it on
and off. Have defective switches replaced by an authorized service center.
10.Stand beside the bench grinder during start-up, not directly in front. Never stand or
have any part of your body in line with the path of the wheel.
11.Never start the grinder when the wheel is in contact with the workpiece.
12.Always hold the workpiece firmly against the work rest.
13.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.
14.Do not use the grinding wheel to cut anything.
15.Do not apply excess stress to the grinding wheel. Excessive pressure may damage
the tool, cause the motor to overheat, and prematurely wear down the grinding wheel.
16.New wheels may require dressing to make them round. Use a grinding wheel dress-
ing tool (not included) to shape or remove glaze from grinding wheels.
Your risk from these exposures varies depending on how often you do this type of work.
To reduce your exposure to these chemicals, work in a well-ventilated area with approved
safety equipment such as dust masks specially designed to filter out microscopic particles.

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 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 licensed electrician or service personnel if you do not completely under-
stand the grounding instructions or whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that
have threepronged plugs and outlets that accept
the tool’s plug as shown in Fig. 1.Repairor replace
a damaged or worn cord immediately.
CAUTION: In all cases, make certain the outlet in
question is properlygrounded. If you are not sure,
have a licensed electrician check the outlet.
17.Keep the distance between the wheel and tool rest at most a 1/8-inch (3.2 mm) space.
Adjust the work rest accordingly as the wheel grinds down to a smaller diameter with
use over time.
18.Guard against electrical shock by preventing body contact with grounded surfaces.
For example: pipes, radiators,ranges, refrigerator enclosure, etc.
19.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.
20.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.
21.Do not turn the 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.
22.Frequently clean grinding dust from beneath the grinder.
23.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.

WARNING: This tool is for indoor use only. Do not expose to rain or use in
damp locations.
WARNING: This tool must be grounded while in use to protect the operator
from electric shock.
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 connecting 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 alower
voltage will damage the motor.
