h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories. 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.
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, 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.
h ) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
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.

Additional Specific Safety Rules
Safety Warnings Common for Grinding,
Sanding, Wire Brushing and Abrasive
Cutting-Off Operation
a ) This power tool is intended to function as a
grinder, sander, wire brush or cut‑off tool. Read
all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.
b ) Operations such as polishing are not
recommended to be performed with this
power tool. Operations for which the power tool
was not designed may create a hazard and cause
personal injury.
c ) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
d ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the
power tool. Accessories running faster than their rated
speed can break and fly apart.
e ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can not
be adequately guarded or controlled.
f ) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g ) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel 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.
h ) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various operations.
The dust mask or respirator must be capable of
filtrating particles generated by your operation.
