For 6904VH only
When driving screws, install a bit adapter (optional
accessory) on the tool and insert a driver bit (optional
accessory) into the bit adapter.
Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw. Start the tool
slowly and then increase the speed gradually. Release
the switch trigger just as the screw bottoms out.

NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• Hold the tool pointed straight at the screw or the screw
and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece. The pilot holes should be slightly smaller than the wood
screws in diameter.
