• Due to our continuing program of research and development, the specications herein are subject to change
without notice.
• Specications may di󰀨er from country to country.
• The weight may di󰀨er depending on the attachment(s). The lightest and heaviest combination, according to
EPTA-Procedure 01/2014, are shown in the table.
Symbols
The followings show the symbols which may be used
for the equipment. Be sure that you understand their
meaning before use.
Read instruction manual.
Wear safety glasses.
Always operate with two hands.
Do not use the wheel guard for cut-o󰀨
operations.
DOUBLE INSULATION
Only for EU countries
Due to the presence of hazardous compo-
nents in the equipment, used electrical and
electronic equipment may have a negative
impact on the environment and human
health.
Do not dispose of electrical and electronic
appliances with household waste!
In accordance with the European Directive
on waste electrical and electronic equip-
ment and its adaptation to national law,
used electrical and electronic equipment
should be collected separately and
delivered to a separate collection point
for municipal waste, operating in accor-
dance with the environmental protection
regulations.
This is indicated by the symbol of the
crossed-out wheeled bin placed on the
equipment.
Intended use
The tool is intended for grinding, sanding, wire brush-
ing, hole cutting and cutting of metal and stone materi-
als without the use of water.
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.

Noise
The typical A-weighted noise level determined according to EN62841-2-3:
Model Sound pressure
level (LpA) : (dB(A)) Sound power level (LWA) : (dB(A)) Uncertainty (K) : (dB(A))

GA4591 90 98 3

GA5092 93 101 3
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 di󰀨er 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 o󰀨 and when it is running idle in addition to the trigger time).
WARNING: Grinding thin sheets of metal or other easily vibrating structures with a large surface can
result in a total noise emission much higher (up to 15 dB) than the declared noise emission values.
Set heavy exible damping mats or such to those workpieces to prevent them from emitting sound.
Take the increased noise emission into consideration for both the risk assessment of noise exposure and
selecting adequate hearing protection.
Vibration
The vibration total value (tri-axial vector sum) determined according to EN62841-2-3:

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 di󰀨er 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 o󰀨 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 di󰀨erent.
EC Declaration of Conformity
For European countries only
The EC declaration of conformity is included as Annex A
to this instruction manual.
SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, re 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.
Grinder safety warnings
Safety warnings common for grinding, sanding,
wire brushing, or cutting-o󰀨 operations:
1. This power tool is intended to function as a
grinder, sander, wire brush, hole cutter or cut-
o󰀨 tool. Read all safety warnings, instructions,
illustrations and specications provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, re and/
or serious injury.
2. Operations such as polishing are not to be
performed with this power tool. Operations for
which the power tool was not designed may create
a hazard and cause personal injury.
3. Do not convert this power tool to operate in
a way which is not specically designed and
specied 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-
cically designed and specied 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 y apart.
