WPTC (2.4GHZ) TORQUE WRENCH OPERATING INSTRUCTIONS
Models to which these instructions apply:
WPTC-5 WPTC-15 WPTC-25 WPTC-60
WPTC-100 WPTC-200 WPTC-300 WPTC-400
WPTC 2.4 GHz torque wrenches are designed and manufactured to provide consistent
torque application in multiple manufacturing and maintenance applications. They meet or
exceed the requirements of ASME B107.300 and ISO 6789. These wrenches are accurate
to +/-4% of the preset value from 20% to 100% of rated capacity.
Interchangeable Heads
Any Bahco interchangeable head may be used with the wrench. Note: It is imperative that
the head used to preset the torque wrench have the same common centerline length as
the head that will be used in assembly. Failure to do so will create a different torque output
during assembly than that which was preset.
Torque Setting
A torque tester of +/- 1% indicated value
accuracy or better, an especial Combination
Adjusting and Release Tool (CART) (shown
at right), and an interchangeable head
having the same common centerline length
as the head that will be used in assembly
and capable of engaging the tester are
required.
Torque
Adjustment
Key
Locking Key

WPTC
1. Insert the Torque Adjustment Key fully into the rear of
the wrench so the hex engages the adjustment nut. Do
not engage the Lock Key. Rotate the Torque Adjustment
Key slightly clockwise to disengage the adjustment nut
from the lock nut.
2. Slide the Lock Key in until it engages the lock nut. You
may need to rotate the lock key slightly to align it with
the internal hex of the lock nut. Rotate the Lock Key
counterclockwise several turns to assure the lock nut is
fully disengaged from the adjustment nut and that there
is sufcient travel available for the adjustment nut to
attain the torque setting desired.
3. Install the interchangeable head on the wrench. Engage
the wrench to the tester and click the wrench once or
twice while noting the readings. To adjust the wrench
to a higher torque setting, rotate the Torque Adjustment
Key clockwise. To adjust the wrench to a lower torque
setting, rotate the Torque Adjustment Key counter-
clockwise. Torque adjustments should be made in small
increments with several checks made between each
movement of the Torque Adjustment Key.
4. Once the desired torque has been attained, hold the Torque Adjustment Key steady and
rotate the Lock Key clockwise until the lock nut rmly engages the torque adjustment
nut, locking it in place. Remove the CART from the wrench and perform a nal torque
check on the tester. When the reading matches the desired torque and the lock nut is
rmly engaged to the torque adjustment nut, the procedure is complete.
Radio Communications - 2.4 GHz Communication Overview
These tools use the 2.4GHz band for communication with the controller. As with all
radio communications, there are limits on the distance at which reliable bi-directional
communication may be obtained. Physical barriers such as steel framing, sheet metal and

7
other objects that impede radio waves can signicantly reduce the reliable communication
distance. Another factor affecting the reliability and distance combination is the radio
environment in which the unit will be used.
The controller and torque wrench may operate on any of the 12 channels these products
use. It is generally best to think about this even before the unit is installed.
The radio modules in the controllers and torque wrenches used with them comply with the
IEEE 802.15.4 standard. The channel numbers loosely match the channels used by the
IEEE 802.11b/g WLAN standard. It may be benecial to use channels that do not match the
channels used by a nearby wireless network. The graph below depicts both standards and
illustrates the center frequencies and channel overlap for each standard.
Notice that the channels we use leave a much smaller footprint than WLAN. Also notice
that one WLAN channel radiates energy onto several of the adjacent WLAN and process
monitor (PM) channels.
For the most reliable communication
between the Bahco PM and the tool in a
802.11b/g LAN environment, it is usually
best to choose a channel for the controller
and tool that is separated from the channel
of the LAN.
Unlike IEEE 802.15.1 (Bluetooth) radios,
our 2.4GHz radio modules do not frequency
hop, use less power and have faster
response times with less impact on other
wireless devices. A wrench only transmits
a small packet of data after each torque
operation, and each transmission lasts
about 30ms (0.03 seconds).
The 2.4GHz radio used by the unit and the
tool is certied in the United States (FCC),
Canada (IC), and Europe (CE).

Establishing RF Communication With Bahco Process Monitors
The transceiver in the PM and the one in the torque wrench each have identication
numbers. When communication between the two is rst established, the numbers are
exchanged and stored in memory. The PM and tool will thereafter ignore communications
from other radios until the number stored in memory is replaced with a different identication
number.
The second element is that under all conditions the controller and the tool to be used with it
must be on the same channel. If the channel on the controller is changed and the channel on
the tool is not, they will not communicate or will cease communicating if they have previously
been associated with each other.
To remove the identication of the unit from the tool memory, click the wrench and hold it
in the clicked position until the LED on the wrench ashes. This will take about 5 seconds.
Release the pressure on the tool and allow it to return to the normal position.
The ashing of the LED occurs when the Process Monitor with which the tool was associated
has been erased. The tool is now ready to be associated with another PM\.
Note that when the battery has been removed and replaced in the wrench the LED will
alternate between emitting red and green light several times very quickly. If the alternating
color emission stops and then a red light pulse is emitted, the tool is not associated with
a specic controller and can be associated with whatever unit is desired. If the alternating
color emission stops and then a green light pulse is emitted, the tool has a specic controller
unit identication number in memory and is ready to be used with that unit.
To establish communication with the controller, it is necessary to follow the instructions
included with the specic controller to be used.
Raised LED Fresnel emits Green or Red during the “learning in” or
radio connection process.
Even when faceplate is tilted away from the user the raised Fresnel
is easily seen.
Battery and Battery Replacement
These tools are shipped with an alkaline battery. Always respect polarity requirements for
our tools.
1. The battery compartment is located directly under the LED on the underside of the
wrench. Turn the wrench over so the face plate is facing the oor.

2. Use a pen head or small screwdriver to
depress the battery cover security spring
and slide the battery cover plate off.
3. Remove the old battery and recharge it.
4. Reinstall the battery and battery cover.
5. Note: We strongly urge that NiMH
rechargeable AAA batteries are the
only battery used in these products.
Other batteries have different operating
characteristics and are highly unlikely to
provide satisfactory performance.
Radio Transceiver Replacement
Under normal circumstances the transceiver is well protected and the system is robust and
durable. This procedure should only be needed on rare occasions.
1. Remove the four screws in the radio
housing and gently lift the cover straight
up off of the internal components.
2. The radio board is now visible.
Notice the location of the spring steel
trigger on the micros witch (red arrow
on right). The trigger location is critical
to tool function. The screw rising from
inside the wrench (indicated by red
arrow on left) triggers the micros witch
that activates the electronic functions. When the electronics are reassembled the trigger
must be on the inside of this screw for the tool to function.
3. Gently lift the circuit board off of the mounting plate without damaging the gray insulating
paper between it and the mounting plate. The insulating paper is essential to preventing
shorts on the circuit board. Examine the paper for tears and replace if torn or damaged
4. Reassemble the components in the reverse order oft heir removal. Place the circuit
board on the insulating paper on the mounting plate, ensuring that the micros witch
trigger is inside the activating screw. Install the upper cover and screws holding it in
place. Then install the battery in the battery holder and slide the battery cover back to
the original position.
Operation & LED’s
Once the tool has been preset, the appropriate interchangeable head installed and the
radio transceiver has been associated with the appropriate controller and specications
exchanged, the tool is ready for use. In normal operation, the tool will emit a strong tactile
and sound impulse when it clicks. If the tool is jerked (too little time in the clicked position)
the LED on the tool will not illuminate. If the tool has been properly used (force applied,
click attained, force released within specied time frame) the LED on the circuit board will

WPTC
illuminate with a green color. This will shine through the cover and be highly visible. If the
tool has been pulled past the click (too much time in the clicked position) the LED on the
circuit board will illuminate with a red color. Under either of the latter two circumstances, the
information will be immediately transmitted to the controller.
Reversible ratchet heads
Even though the ratchet is reversible, the tool only applies measured and controlled torque
in the clockwise direction, so thought must be given to the task to be accomplished before
the ratchet is reversed and the tool used in the counter-clockwise direction. Exceeding the
capacity of the tool in a CCW torque application is likely to damage the tool and is not
covered by warranty.
Cleaning
This wrench should be cleaned with a soft cloth dampened with water. Do not immerse this
tool in liquid or use any solvent other than water to clean the tool.
Presetting, Calibration and Repair
Presetting from our Internal After Sales Centers is available. Contact your Bahco distributor
for details. Parts and factory repair are also available.
