Over Heat Protection (OHP) and Over Current Protection (OCP) Settings.

The BF drivers offer Over Heat Protection (OHP) and Over Current Protection (OCP) to protect the driver from damage or malfunc­tion. Features a LED display that signals the tool status for the operator. It’s located on the side. Below is the LED display indicator for
reference.

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.

9. To remove the screw, turn the FOR/REV switch to REV.

Torque Cover

(BF035 & BF045 models only)

Item # 145773

Protects from incidental or operator tampering of torque setting.

The EZ-Glider torque arms are designed to improve production and quality control during the assembly
process. The arms securely keep electric or pneumatic drivers in perpendicular alignment to help prevent
side loading or cross threading occurring during the assembly process. The EZ-Glider helps remove the
operator’s influence in the assembly process and strengthens quality control.

The ergonomic design of the EZ-Glider torque arms reduces RMI (repetitive motion injury) and CTS
(carpal tunnel syndrome). The effortless handling of the torque arm provides comfortable tool operation
and increased production. The torque arm can be installed in space-restricted areas.

Accessories

Screw Counter

Scout screw counter helps manufacturers detect and eliminate costly screw-fastening errors during the
assembly process. Using a screw counter is like putting the eyes and ears of a quality control manager
where they are needed most - right on the assembly area. The Scout is designed to detect cross
threading, omissions, unfinished rundowns and cycle complete. The screw counter takes the control of
the assembly process out of the operator's hands.

Item # 145790

Screw presenters are small, tabletop devices used to organize and automate work areas and produc­tion cells. Screw presenters make assemblers and the assembly process more efficient by mechanical­ly presenting a screw to a fixed pick up point. The inexpensive screw presenter is an alternative tool
instead of the cumbersome and very expensive screwfeeder systems.

Vacuum Adapter Kit

For: BF035 & BF045 models

Item # 145653

Vacuum adapter kits can be mounted on an electric screwdriver. The screwdriver is fitted with a suction head that holds the screw on
the bit, enabling the operator to pick it up with the tool itself. This is an effective, time saving device that works with most fasteners.

- Accepts different size screws and various length fasteners.

- Allows quick-change set-up at a low cost.

- Mounts with threaded torque nut. The driver remains externally adjustable while allowing semi-automatic pickup of non-ferrous
fasteners.

- Plug driver into vacuum supply or chose the Vacuum Ejector.

- Mouthpiece and bit purchased separately.

Torque Charts

These charts are meant to be used as guidelines for setting the torque on the BF-Series electric screwdrivers. The
drivers have a torque scale on the torque adjustment nut showing reference numbers. These numbers determine the
approximate torque setting. Refer to the charts to determine the reference number setting for your torque requirement.

How to Read the Torque Charts
Torque ranges (lbf.in) approximate tightening torque. Figures below each chart indicate scale setting on the tool. Some

drivers have more than one spring. Select the appropriate spring to achieve the desired torque setting.

Testing Power Tools:

1. Application Method: Use a torque analyzer in “Peak Mode” with a rotary transducer between the power tool and the actual
application. This is the best way to test since you are using the actual joint as the test station. You will see the actual

torque applied to the fastener. Caution: Variances in tool performance may occur do to the addition of the rotary transducer.

2. Simulated Method: Always use a quality joint rate simulator (run down adapter) with a torque analyzer when testing power

tools in a simulated application. Use Joint rate and Breakaway methods to obtain most accurate torque readings in a
simulated rundown.

Care

1. The BF-Series screwdrivers are a precision torque control instrument and should be handled with care at all times.

2. Only use the transformers listed in the Mountz catalog or website for appropriate BF-Series driver model (If you have any questions

regarding the appropriate transformer set-up, contact Mountz Customer Service Department).

3. Operate under safe conditions. Do not place in operation where such objects as hair, strings, clothing, etc. can become

tangled in the rotating bit.

4. Keep away from moisture. Never use in high humid, moist or damp environment.
