Never cut pieces that are too small.
Support long workpieces with helping
roller stands.
Large, circular or irregular shaped

Do not cut more than one workpiece
at a time.
Remove cut and jammed workpieces
only when motor is turned off and the

Operation:
Always observe the safety
instructions and adhere to the
current regulations.
Ensure that the wheel guards are in
the correct position before you start
sawing.
The chop saw is switched on by
means of the trigger switch (A, Fig 3)
that is situated on the inside of the
control handle.
Allow the abrasive wheel to reach full
speed before cutting.
Push the cutting head slowly and
evenly downwards.
The cutting head must be returned
carefully to its starting position after
cutting.
To stop the saw release the trigger.
Allow the abrasive wheel to come to a
complete standstill before using the
saw again or making adjustments.
Attention:
The condition of the abrasive wheel
should be checked before each
machining process.
Work only with flawless abrasive
wheels.
Do not allow anyone to stand behind
the saw or close to the workpiece
where debris can be thrown.
Flying sparks will occur when cutting.
They can cause injury and ignite
flammable materials.
