DOUBLE INSULATION
Only for EU countries
Do not dispose of electric equipment
together with household waste material! In
observance of the European Directive, 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 col-
lected separately and returned to an envi-
ronmentally compatible recycling facility.
Intended use
The tool is intended for cutting in ferrous materials with
appropriate abrasive cut-off wheel. Follow all laws and
regulations regarding dust and work area health and
safety in your country.
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.

Power tool use and care
1. Do not force the power tool. Use the correct
power tool for your application. The correct
rate for which it was designed.

Cut-off machine safety warnings
1. Position yourself and bystanders away from
the plane of the rotating wheel. The guard helps
to protect the operator from broken wheel frag-
ments and accidental contact with wheel.
2. Use only bonded reinforced cut-off wheels for
your power tool. Just because an accessory can
be attached to your power tool, it does not assure
safe operation.
3. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of a cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to
shatter.

accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.

may cause loss of control.
8. Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If the
power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool
at maximum no load speed for one minute.
Damaged wheels will normally break apart during
this test time.

materials. Do not operate the power tool while
placed on a combustible surface such as
wood. Sparks could ignite these materials.
14. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
stalling of the rotating wheel which in turn causes the
uncontrolled cutting unit to be forced upwards toward
the operator.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface
of the material causing the wheel to climb out or kick
out. Abrasive wheels may also break under these
conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
1.
position your body and arm to allow you to
resist kickback forces. The operator can control
upward kickback forces, if proper precautions are
taken.
2. Do not position your body in line with the
rotating wheel. If kickback occurs, it will propel
the cutting unit upwards toward the operator.
3.
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.
Such blades create frequent kickback and loss of
control.
4.
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of kick-
back or wheel breakage.
5. When the wheel is binding or when interrupt-
ing a cut for any reason, switch off the power
tool and hold the cutting unit motionless until
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
6. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
7.
the risk of wheel pinching and kickback. Large
workpieces tend to sag under their own weight.
Supports must be placed under the workpiece
near the line of cut and near the edge of the work-
piece on both sides of the wheel.

operation; it is extremely hot and could burn
your skin.
14. Store wheels in a dry location only.

INSTALLATION
WARNING: This tool produces spark when
cutting a workpiece. Do not install this tool in

tool. Also make sure that there is no such material
near the tool before starting the operation.
Securing the base
