Intended use

The tool is intended for grinding without the use of
water.
Noise
The typical A-weighted noise level determined according to EN60745-2-3:

GA5051R
NOTE: The declared noise emission 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 noise emission value(s) may also be used in a preliminary assessment of exposure.
WARNING:
Wear ear protection.
WARNING:
The noise emission during actual use of the power tool can differ from the declared val-
ue(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).
Vibration
The vibration total value (tri-axial vector sum) determined according to EN60745-2-3:
Work mode: surface grinding with normal side grip

Power supply

The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
