• Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used on
• Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in
the Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of electric shock or injury.

Specific Safety Rules
• Always use proper guard with grinding wheel. A guard protects operator from broken
wheel fragments. Always position the guard so that as much of the exposed disc as
possible is pointing away from you.
• Accessories must be rated for at least the speed recommended on the tool warning
label. Wheels and other accessories running over rated speed can fly apart and cause
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will
make exposed metal parts of the tool "live" and shock the operator.
Additional Safety Rules
• ALWAYS WEAR EYE PROTECTION.
• WEAR EAR PROTECTION. NOISE LEVEL MAY BE AMPLIFIED WHEN GRINDING IN
• KEEP GUARDS IN PLACE.
• Use only accessories having a maximum operating speed at least as high as the speed
specified in the warning on the tool’s label.
• Before using, inspect recommended accessory for cracks or flaws. If such a crack or flaw
is evident, discard the accessory. The accessory should also be inspected whenever you
think the tool may have been dropped.
• When starting the tool (with a new or replacement wheel or brush installed) hold the tool in
a well protected area and let it run for one minute. If the wheel or brush has an undetected
crack or flaw, it should burst or separate in less than one minute. Never start the tool with
a person in line with the accessory. This includes the operator.
• In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the
tool and inspect the wheel.
• ALWAYS USE GUARDS with grinding wheels and wire brushes. Always position the
guard so that as much of the exposed wheel or wire brush as possible is pointing away
• Clean your tool out periodically.
• Do not use Type 1 flat cut-off abrasive or diamond wheels without proper guard. (Guard
not included with unit.)
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
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, and work with
approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disperse dust, which may cause
serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved
respiratory protection appropriate for the dust exposure. Direct particles away from face and
CAUTION: Wear appropriate hearing protection during use. Under some conditions
and duration of use, noise from this product may contribute to hearing loss.
• Do not operate this tool for long periods of time. Vibration caused by the operating
action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to
provide extra cushion, take frequent rest periods, and limit daily time of use.

General Safety Rules
WARNING! Read and understand all instructions. Failure to follow all instructions
listed below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
• Keep your work area clean and well lit. Cluttered benches and dark areas invite
• Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or
• Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
• Double insulated tools are equipped with a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit
fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician
to install a polarized outlet. Do not change the plug in any way. Double insulation
eliminates the need for the three wire grounded power cord and grounded power supply
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
• Don’t expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
• Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
• When operating a power tool outside, use an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor use and reduce the risk of electric shock.
• Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use tool while tired or under the influence of drugs, alcohol, or
medication. Amoment of inattention while operating power tools may result in serious
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your
hair and clothing away from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts.
• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or key that is
left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
• Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to a loss
• Do not force tool. Use the correct tool for your application. The correct tool will do the
job better and safer at the rate for which it is designed.
• Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing the tool. Such preventative safety measures reduce
the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind and are easier to control.
INFORMATION YOU SHOULD KNOW
• Wait until grinding wheel reaches full speed before applying work.
• Hold grinder at proper angle, as shown in Figure 11 and 12.
