General Operation for BF-Series models
1. Attach cord to the BF screwdriver. Make sure notch in plug lines up with the notch on the socket.
Tighten knurled ground ring.
2. Plug in transformer and check power indicator. If it is not on, check fuse in the transformer.
3. Attach cord to the transformer (Transformer required to operate the tool). Make sure notch in plug
lines up with the notch on the socket. Tighten knurled ground ring.
4. Select a bit. Retract the bit collar. Insert the bit and release the retracted collar. To avoid damaging
fasteners, make sure the proper bit is suitable for the head of the fastener.
5. The torque limit is determined by the tension of the coil spring housed in the torque adjustment nut.
The tighter the coil spring is wound the higher the torque limit is raised. See Charts on page 7 to determine the appropriate
torque adjustment setting.
6. Rotate the torque adjustment nut to set the torque limit. Turn clockwise to increase torque and counter clockwise to
decrease torque. The scale adjacent to the Torque Adjustment Nut is a reference guide. The torque output from the
driver can change depending on various fastening factors like friction, type of joint, and the type material being used
like a washer.
7. Turn driver on and check for proper rotation. FOR-clockwise, REV-counterclockwise.
8. To apply torque, squeeze the lever. The driver will automatically stop when the preset torque has been reached.
