Screwdriving
• For best results, hold the screwdriver with the
hand directly in line with the fastener and press
the variable speed switch with the last one
or two fingers of the hand. This reduces the
chance of the screw slipping from the drive
accessory when pressure is applied.
• To drive the fastener, place it on the bit or into
the socket or nutsetter, press the variable speed
switch and push the fastener into the workpiece
with a smooth, continuous motion. When the
fastener is seated, the clutch will disengage
automatically.
Various types of 1/4" hex bits, holders, sockets and
