SAFETYOPERATIONMAINTENANCE SETUP
Personal safety
1� 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
tools may result in serious personal injury.
2� Use personal protective equipment.
Always wear eye protection.
Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
3� Prevent unintentional starting.
Ensure the Switch is in the off-position
before connecting to power source, picking
up or carrying the tool.
Carrying power tools with your finger on
the Switch or energizing power tools that
have the Switch on invites accidents.
4� Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the power
tool in unexpected situations.
5� 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.
6� If devices are provided for the connection
of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these devices
can reduce dust-related hazards.
7� Only use safety equipment
that has been approved by an
appropriate standards agency.
Unapproved safety equipment may
not provide adequate protection.
Eye protection must be ANSI-approved and
breathing protection must be NIOSH-approved
for the specific hazards in the work area.
Power tool use and care
1� 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.
2� 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.
3� Disconnect the battery pack from
the power tool before making any

storing power tools. Such preventive
safety measures reduce the risk of
starting the power tool accidentally.
4� 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.
5� 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.
6� Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
7� 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 result in a hazardous situation.

SAFETY OPERATION MAINTENANCESETUP
Safety Warnings Specific for Grinding and
Abrasive Cutting-off Operations
1� Use only wheel types that are
recommended for your power tool and
the specific guard designed for the
selected wheel. Wheels for which the
power tool was not designed cannot be
adequately guarded and are unsafe.
2� 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.
3� Always use undamaged wheel flanges
that are of correct size and shape for your
selected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of
wheel breakage. Flanges for cut-off wheels
may be different from grinding wheel flanges.
4� 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.
5� Dress appropriately.
Do not wear pants with cuffs,
shirts with open pockets, or any clothing that
can catch and hold molten metal or sparks.
Safety Warnings Specific for Wire Brushing Operations
Be aware that wire bristles are thrown by the brush even during ordinary operation.
Do not overstress the wires by applying excessive load to the brush.
The wire bristles can easily penetrate light clothing and/or skin.
