WARNING
Driving Screws
Variable-speed control must be used
with caution for driving screws using bit
attachments. The best technique is to start
slowly, increase the speed as the screw
runs down, and then set the screw snugly by
slowing the tool to a stop. If this procedure is
not followed, the tool will have a tendency to
torque or twist in your hand when the screw
seats.
a. Install a suitable bit.
b. Apply just enough pressure to keep the bit
engaged on the screw.
c. Apply minimal pressure to the variable-
speed trigger switch intially. Increase the
spped only when full control can be maintained.
NOTICE:
a. Always use the correct type and size of bit for your application.
b. When turning in a screw at/near the cross cut end or an edge of wood, pre-drill a pilot hole
in order to avoid cracking of the wood.
c. When screw driving in hard wood, one should pre-drill a pilot hole.
WARNING
avoid damaging the fastener head .
