Plunge cuts (Pocket cutting)
WARNING:
Never touch the lower guard during operation.
•
Never wedge or tie the lower guard open. For
•
example, do not wedge or tie the retracting lever.
Then lower guard must always be kept free and in
no way restricted in its movement. It must
automatically close immediately after the cut is
completed and the tool is raised.
As soon as you start the cut, release the retracting
•
lever. The lower guard contact with the workpiece
will keep it in position to open freely as you start
the cut.
Lower guard should be retracted manually only for
•
special cuts such

Retracting Lever. As soon as blade enters the
material, retracting lever must be released. For all
other sawing, the lower guard should operate
automatically.
Tilt the tool forward and rest the front of the base on the
workpiece to be cut. Using the right edge of the notch in
the front of the base and the graduation on the right side
of the base, align the blade with the cutting line on the
workpiece. Grasp the tool firmly with the front grip by
your left hand and the rear handle by your right hand.
Switch on the tool and wait until the blade reaches full
speed. Push down the retracting lever with your thumb
to retract the lower guard. As soon as you start the cut,
release the retracting lever. Gradually lower the tool until
its base rests flat on the workpiece to be cut. Then
advance the tool along the cutting line until the cut is
completed. Release the switch trigger and allow the
blade to stop completely before withdrawing the blade
from the workpiece. Never withdraw the blade when it is
still rotating. A dangerous kickback could occur.
