SAFETY PRECAUTIONS
Be Sure To Follow All Safety Rules In This Manual!

and/or serious injury.
• The term “power tool” in all of the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
• Save all warnings and instructions for future reference.
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not
matching outlets will reduce risk of electric shock.
• 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.
• Do not 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 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.
• When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• Stay alert, watch what you are doing and use common sense when operating a
drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and / or battery pack, picking up or carrying the tool.
have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
• 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.
• If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection can

Power Tool Use and Care
Service
• 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.
• 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.
• 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.
• 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.
• Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tool’s operation.
If damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
replacement parts. This will ensure that the safety of the power tool is maintained.

the spindle of the power tool. Accessories with arbor holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate excessively and may cause loss
of control.
• Do not use a damaged accessory. Before each use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and installing an accessory, position yourself
and bystanders away from the plane of the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged accessories will normally break apart
during this test time.

Kickback and Related
Warnings
Grinding and Abrasive
Cutting-Off Operations:
resist kickback forces. Always use auxiliary handle, if provided, for maximum control
reactions or kickback forces, if proper precautions are taken.
• Never place your hand near the rotating accessory. Accessory may kickback over your
hand.
• Do not position your body in the area where power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite to the wheel’s movement at the point of
snagging.
• Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create
designed for the selected wheel. Wheels for which the power tool was not designed cannot
• The guard must be securely attached to the power tool and positioned for maximum
safety, so the least amount of wheel is exposed towards the operator. The guard helps to
protect operator from broken wheel fragments and accidental contact with wheel.
• Wheels must be used only for recommended applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to shatter.
• Do not use worn down wheels from larger power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a smaller tool and may burst.
• Keep bystanders a safe distance away from work area. Anyone entering the work area
• Hold power tool by insulated gripping surfaces only, when performing an operation where
the cutting accessory may contact hidden wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal parts of the power tool “live” and shock
the operator.
• Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into the spinning accessory.
• Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your control.
• Do not run the power tool while carrying it at your side. Accidental contact with the
spinning accessory could snag your clothing, pulling the accessory into your body.
• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the
materials.
may result in electrocution or shock.
Safety Precautions
Additional Safety Warnings
Cutting-Off Operations:
• Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and the possibility of kickback or wheel
breakage.
• Do not position your body in line with and behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your body, the possible kickback may propel
the spinning wheel and the power tool directly at you.
• When wheel is binding or when interrupting a cut for any reason, switch off the power tool
and hold the power tool motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective action to eliminate the cause of wheel
binding.

kickback. Large work pieces tend to sag under their own weight. Supports must be placed
under the work piece near the line of cut and near the edge of the work piece on both sides
of the wheel.
• Use extra caution when making a “pocket cut” into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause
kickback.
