7. Securely fix the cutting material. Ensure that
the material is securely fastened with the vise.
If it is not, a serious accident could be caused if
the material comes loose or the cut-off wheel
breaks during operation.
8. Check the Power Receptacle. To prevent over-
heating or accidental stopping, confirm that the
power plug fits properly in the electrical recep-
tacle and does not fall out after it is inserted.
Repair or replace the receptacle, if it is faulty.
9. Confirm that the tool’s power cable is not
damaged. Repair or replace the power cord if
an inspection of the cab tire cable indicates that
it is damaged.
AFTER CONNECTING THE POWER PLUG TO AN
APPROPRIATE AC POWER SOURCE, CHECK THE
OPERATION OF THE TOOL, AS FOLLOWS:
• Trial Run. After confirming that no one is
standing in front of it, step away from the front
position and start the power tool and confirm
that no operating abnormalities exist before at-
tempting a cutting operation. Trial run periods:
When replacing the cut-off wheel;
Over 3 minutes.
When starting routine work; Over 1 minute.
• Inspect the rotating stability of the cut-off
wheel. For precise cutting, rotate the cut-off
wheel and check for deflection to confirm that
the wheel is not noticeably unstable; otherwise
vibration might occur and cause an accident.
PRACTICAL APPLICATIONS
WARNING: Never remove or install a work-
piece while the cut-off wheel is rotating to
avoid personal injury.
PROCEDURE TO PLACE THE CUTTING MATERIAL
It is important that the material is safely
clamped in the double material vice, so that it
cannot tilt over or even move during sawing. In
order to work efficiently, the material must al-
ways be clamped in such a way that the contact
surface of the saw and the material is as small
as possible.
For instance, saw flat material on its thinnest
side; this will considerable shorten sawing times.
When very short pieces have to be sawn, and
consequently only half of the material vice will
be used, in order to prevent it from pulling out
of alignment, a piece of material of equal thick-
ness must be clamped in the other half of the
vice. In this way the material is clamped tightly
and evenly. Application of special vice jaws is
recommendable for repetitive work.
SWITCH OPERATION
NOTE: Make sure the material has been fed.
• Check the depth setting of the saw blade.
• Check whether the vice jaws are suited for this
material.
• Adjust the material vice to the material.
• Switch on the machine with the main switch.
• Select the required speed.
• Open the coolant cock on the safety guard
(not in case of atomized lubrication).
• Start machine with the switch on the pulling
rod.
WARNING: Always release the lock-off but-
ton from the handle when the power tool is
not in use. If the lock-off button is left on in the
handle, serious personal injury could result.
OPERATION INSTRUCTIONS
SELECTION OF THE SAW BLADE
The selection of the correct blade depends on
the material to be cut. The selection of the cor-
rect cutting blade and rake angle is of great
importance for the life of the cut-off machine.
CUTTING CAPACITY

ule for the profile figure/cross-cut in relation-
ship with the mitre angle. Whit 90º we mean
straight cutting.

OPERATION
1. Turn ON the cut-off wheel, gently press down
the handle, and bring the cut-off wheel close to
the material to be cut.
2. When the cut-off wheel contacts the mate-
rial, gently press down the handle further and
start cutting.
3. When cutting (or designated slotting) is com-
pleted, raise the handle and restore it to its
original position.
WARNING: Confirm that the trigger switch
is turned OFF and that the power plug has been
removed from the receptacle, whenever the
tool is not in use.
CAUTION: Increased pressure on the handle
will not increase the cutting speed. On the con-
trary, too much pressure may result in overload of
the motor and/or decreased cutting efficiency.
CUTTING AT ANGLES
The machine permits cutting at angles of 45°.
