Symbols
The following show the symbols used for the equipment.
Be sure that you understand their meaning before use.
･ Read instruction manual.
･ DOUBLE INSULATION
･ Only for EU countries
Do not dispose of electric equipment
together with household waste material!
In observance of European Directive
2002/96/EC on waste electric and
electronic equipment and its
implementation in accordance with
national law, electric equipment that
have reached the end of their life must
be collected separately and returned to
an environmentally compatible recycling
facility.
ENE036-1
Intended use
The tool is intended for fastening bolts and nuts.
ENF002-2
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.

•
The declared vibration emission value has been
measured in accordance with the standard test
method and may be used for comparing one tool
with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
