it cools or you will be burned!
Operation:
Always observe the safety
instructions and adhere to the
current regulations.
Ensure that the blade guard is in the
correct position before you start

that is situated on the inside of the
control handle.
Allow the saw blade 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 saw blade to come to a
complete standstill before using the
saw again or making adjustments.
Attention:
The condition of the saw blade should
be checked before each machining
process.
Work only with flawless saw blades.
Do not allow anyone to stand behind
the saw or close to the workpiece
where debris can be thrown.
Flying sparks may occur when
