General Operation for BF-Series models

1. Attach power tool cable to the BF-Series screwdriver and the transformer. Make sure notch at the
cable end aligns with the notch on the driver connector. Tighten knurled ground ring.

2. Plug in power cord to the back of the transformer and power outlet. Flip power switch to
“ON” position located on the back of transformer.

3. Select a bit. Slide the bit collar forward. Insert the bit and release the collar. To avoid damaging
fasteners, make sure the proper bit is suitable for the head of the fastener.

4. The torque limit is determined by the tension of the coil spring housed in the tool. The tighter the coil
spring is wound the higher the torque limit is raised. See Torque Charts on pages 14 & 15 to determine the
appropriate torque adjustment setting.

5. 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. Verify torque setting with a torque testing system.

7. Turn driver on and check for proper rotation. FOR-clockwise, REV-counterclockwise.

8. To apply torque, squeeze the lever (Push-to-Start models - place light downward pressure on the nose
of the driver). The driver will automatically stop when the preset torque has been reached.

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

0.4 & 0.6 seconds).

How to Adjust Speed Setting

1. Press and hold the Speed button for 2 seconds.

2. Two LEDs will display colors that show the current speed
selection of the brushless screwdriver.

3. Position the F/R slide switch in R or F to increase (+) or decrease
(-) RPM setting of the tool Slide switch to "R" position to increase
speed. Slide switch to "F" to decrease speed. Then press the
Speed button until the target speed is selected. The two LEDs
will display colors that show the current speed selection (see
table below for reference) Note! The RPM settings can only be
adjusted to the preset increments as shown on the label
(see chart below).

4. By starting the screwdriver, the selected speed is saved

automatically.

Program Lock Key

The Program Lock Key protects from incidental or operator tampering of the
programmable settings on the side of select BF-Series models* (V3 models
only). To adjust the settings the Program Lock Key must be is plugged into
the STC40 & FT-30D Mini Transformer.

Note! The program Key cannot be used with BF-Series Standard Plus
Models, Soft Stop Plus Models & Angle & Auto Reverse Models.

BF-Series Standard Plus Models & Soft Stop Plus Models

The “Plus” models feature a selectable Double Hit Mode
for soft joint applications and a selectable Soft Start mode
(from 0.2, 0.4 & 0.6 seconds). This option is only available
with Standard & Soft Stop “Plus” models.

Double Hit Mode

The Double Hit mode is for very soft joint applications. When
an electric screwdriver runs down a fastener and the tool
clutches off once the preset torque is achieved there can be
some joint relaxation that can occur. The Double Hit mode
has the electric screwdriver perform a second hit to stabilize
the torque for joint relaxation.

Joint relaxation is caused by the surface of part(s) embedding or by "soft parts" such as gaskets, plastics or spongy material, which
collapses under the clamping force created in a torque condition. For Hard Joint applications there is no need to use the Double Hit
mode.

The clutch of the electric driver works twice at the set torque under the "Double Hit" mode. The Double Hit will increase the
repeatability accuracy at the target torque by double checking.

Operating the Double Hit Feature with “Plus” models

The default setting is OFF.

1. Press the Double Hit button for 2 seconds to turn ON Double Hit. (ON Status is indicated with LED - Orange). Note - When the
motor is operating LED will be Green.

Soft Start Mode

There are 3 different time settings for the Soft Start mode which are (0.2, 0.4 & 0.6 seconds). The default setting is OFF.

1. Press the Soft Start button for 2 seconds to turn on Soft Start.

- Soft Start is ON and set for 0.2s (LED - Orange)

- Soft Start is ON and set for 0.4s (LED - Orange blinks 1 time)

- Soft Start is ON and set for 0.6s (LED - Orange blinks 2 time)

The Soft Start button is “wrap around” button meaning you can toggle through the settings continuously by pressing the button
(OFF - 0.2s-0.4s-0.6s).

Vacuum Adapter Kit

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.

Mouthpieces

T orque Arms

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

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, operated on 30V. 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.
