The drill chuck is driven out of the drilling
spindle using the supplied ejector wedge.
To do so, move the drilling spindle down
until the ejector slot in the side of the spind-
le is visible. Insert the ejector wedge into
the slot and strike it with a hammer to drive
out the drill chuck.

cautIon! Workpieces must be
secured against twisting and lif-
ting.
The workpiece may be twisted or pushed
away when fitting the drill bit. Also, the spi-
ral shape of the bit may pull the workpiece
upward and so cause it to be spun around.
This may result in serious injury. So the
workpiece must be secured:
•
Small workpieces should be clamped in
a suitable machine vice. The vice can be
fixed using the grooves in the machine
plate and appropriate fixings (screws and
sliding blocks).
•
Larger workpieces can be fixed directly
on the plate or base using clamp straps.
