General Safety Rules
WARNING! Read all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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 fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock. Replace or repair dam-
aged cords. Make sure your extension cord is in good condition. Use only 3-wire exten-
sion cords that have 3-prong grounding-type plugs and 3-pole receptacles that accept
the tool's plug.
e) When operating a power tool outdoors, use an extension cord suitable for out-
door use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
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 following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heav-
ier gage. The smaller the gage number, the heavier the cord.

3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tool may
result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate condi-
tions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging
in. Carrying power tools with your finger on the switch or plugging in power tools that
have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables bet-
ter control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts. Air vents often cover moving parts and should also be avoided.
g) If devices are provided for the connection of dust extraction and collection facil-
ities, ensure these are connected and properly used. Use of these devices can
reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power
tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools oper-
ation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool,
taking into account the working conditions and the work to be performed. Use
of the power tool for operations different from those intended could result in a haz-
ardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
b) If the replacement of the supply cord is necessary, this has to be done by the
manufacturer or his agent in order to avoid a safety hazard.
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 injury.
• 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
ENCLOSED SPACES.
• 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
from you.
• 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 body.
CAUTION: Wear appropriate hearing protection during use. Under some conditions
and duration of use, noise from this product may contribute to hearing loss.
CAUTION: 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.
