WARNING:
The vibration emission during actual use of the power tool can differ from the declared
value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
WARNING:
Be sure to identify safety measures to protect the operator that are based on an estimation
of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the
times when the tool is switched off and when it is running idle in addition to the trigger time).
WARNING:
The declared vibration emission value is used for main applications of the power tool. However if
the power tool is used for other applications, the vibration emission value may be different.

SAFETY WARNINGS
General power tool safety warnings
WARNING Read all safety warnings, instruc-
tions, 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.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Cordless grinder safety warnings
Safety warnings common for grinding, sanding,
wire brushing, or cutting-off operations:
1. This power tool is intended to function as a
grinder, sander, wire brush, or cut-off tool.
Read all safety warnings, instructions, illus-
trations and specifications provided with this
power tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious injury.
2. Operations such as polishing or hole cutting
are not to be performed with this power tool.
Operations for which the power tool was not
designed may create a hazard and cause per-
sonal injury.
Do not convert this power tool to operate in
3.
a way which is not specifically designed and
specified by the tool manufacturer. Such a con-
version may result in a loss of control and cause
serious personal injury.
4. Do not use accessories which are not spe-
cifically designed and specified by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
5. 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.
6. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
7. The dimensions of the accessory mounting
must fit the dimensions of the mounting hard-
ware of the power tool. 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.
8. 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 maxi-
mum no-load speed for one minute. Damaged acces-
sories will normally break apart during this test time.
9. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
flying debris generated by various applications.
The dust mask or respirator must be capable
of filtrating particles generated by the particular
application. Prolonged exposure to high intensity
noise may cause hearing loss.
10. 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
11.
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
12. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
13. 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.
14. Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
