Power tool use and care
 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 bind-
ing 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 ac-
cordance 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.
Service
 Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Angle Grinder
Safety Warnings common for Grinding, Sanding,
Wire Brushing or Abrasive Cutting Off Operations
 This power tool is intended to function as a grinder,
sander, wire brush or cut-off tool. Read all safety warn-
ings, instructions, illustrations and specifications pro-
vided with this power tool. Failure to follow all instruc-
tions listed below may result in electric shock, fire and/or
serious injury.
 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.
 Do not use accessories which are not specifically de-
signed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
 The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their rated speed can break
and fly apart.

 The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
 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 con-
trol.
 Do not use a damaged accessory. Before each use in-
spect 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 in-
stall an undamaged accessory. After inspecting and in-
stalling 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 min-
ute. Damaged accessories will normally break apart during
this test time.
 Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye protec-
tion 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.
Prolonged exposure to high intensity noise may cause
hearing loss.
 Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken accessory may fly away and cause injury beyond
immediate area of operation.
 Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord. Cut-
ting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the op-
erator an electric shock.
 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 wheel.
 Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel 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 housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.
