pieceswhich cannot be secured firmly
with the vise. The piececut off may be caught by
the blade,causingdangerous scattering of chips and/or damageto the carbide-tips.
Pos-
sible serious injury may result.
*Do not apply excessive pressure on the handle when cutting. Too much pressure
may result in overloadof the motor, decreased cutting efficiency and/or damage to the
carbide-tipsor bladeitself.

amount
of sparks.
When the cut is completed, switch off the tool and WAIT UNTILTHE BLADE HAS COME
TO A COMPLETE STOP before returning the handle to the fully elevated position.
If the
handle is raised while the blade is still rotating, the piece cut off may be caught by the
blade, causing dangerous scattering
of chips. When cutting only part of the way into a
workpiece, raise the handlewhile the blade is rotating. Switching off during the cut may
