Vibration
The vibration total value (tri-axial vector sum) deter -
mined according to EN60745-2-3:
Work mode: surface grinding with normal side grip
Vibration emission (a
h, AG
) : 5.5 m/s 2
Uncertainty (K) : 1.5 m/s
2
Work mode: surface grinding with anti vibration side grip
Vibration emission (a
h, AG
) : 7.0 m/s
2
Uncertainty (K) : 1.5 m/s
2
Work mode: disc sanding with normal side grip
Vibration emission (a
h, AG
) : 2.5 m/s
2
or less
Uncertainty (K) : 1.5 m/s 2
Work mode: disc sanding with anti vibration side grip
Vibration emission (a
h, AG
) : 2.5 m/s
2
or less
Uncertainty (K) : 1.5 m/s

NOTE: The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
NOTE: The declared vibration total value(s) may also
be used in a preliminary assessment of exposure.
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 mea-
sures 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 applica-
tions, 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 Abrasive 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 are not rec-
ommended 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.
3. Do not use accessories which are not specifi -
cally designed and recommended by the tool
manufacturer.
Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
4.
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.
5. 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.
6. 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.
7. 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 acces-
sories will normally break apart during this test time.
8. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appropri-
ate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small
abrasive or workpiece fragments. The eye pro -
tection 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.
9. 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.
