Working Advice
General Cutting Instructions
► Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while working.
► Make sure that the spark guard 22 is properly mounted.
Sparking occurs when cutting metal.
Protect the cutting disc against impact, shock and grease. Do
not subject the cutting disc to lateral pressure. Do not
strain the power tool so heavily that it comes to a standstill.
Excessive feed considerably reduces the performance
capability of the machine and shortens the service life of the
cutting disc. Use only cutting discs that are suitable for the
material to be worked.
Permissible Workpiece Dimensions
Maximal workpiece sizes:
Minimal workpiece sizes (= all workpieces that can be
clamped via the clamping spindle 7): Length 80mm
Cutting depth, max. (0°/0°): 125mm
Cutting Metal
– Set the desired mitre angle.
– Firmly clamp the workpiece as appropriate for its dimensions.
– Switch on the machine.
– Slowly guide the tool arm downward with the handle 3.
– Switch the machine off and wait until the cutting disc
comes to a complete stop.

– Guide the tool arm slowly upward.
Adjusting the Depth Stop (see figure H)
In the delivery condition of the machine, the depth stop 16 is
adjusted in such a manner that a new 355mm cutting disc
does not touch the base plate when cutting. To compensate
the wear of the cutting disc, the depth stop can be set deeper.
When using a new cutting disc, the depth stop must then
always be set back to the original position.
► Always adjust the depth stop in such a manner that the
cutting disc does not touch the base plate when cutting.
– Bring the power tool into the working position. (see
"Releasing the Machine)", page 22.
– Loosen lock nut 29 with the supplied ring spanner 13 (13
mm).
– Swing the tool arm with the handle 3 to the requested position.
– Screw the depth stop 16 in clockwise or anticlockwise
direction until the screw head touches the housing.
– Slowly guide the tool arm upward and tighten the lock nut 29.
Transport
– Always carry the power tool by its transport handle 17.
► The power tool should always be carried by two
persons in order to avoid back injuries.
► When transporting the power tool, use only the
transport devices and never use the protective devices.
