Using the Torque Wrench
1. Attach the appropriate fastener engagement device to the tool (socket or interchangeable head). It is imper-
ative that the interchangeable head used on the SLTC have the same common centerline length as that
used in presetting the torque.
2. Engage the fastener completely with the socket or interchangeable head.
3. Grasp the center of the vinyl grip and with a steadily-increasing force move the wrench in the direction of the
torque arrow on the case.
4. Continue increasing the force until an audible and/or tactile impulse (the “click”) is experienced.
5. Immediately stop applying force to the wrench.
Connecting the Torque Wrench to the Programmable Torque Verifier (PTV)
The SLTC, SLTCS and SLTCR-Series torque wrenches have a threaded connector on the Switch Module, and
the PTV has a two-prong connector on its side. Attach the Switch Wrench to PTV cable to the wrench, then to
the PTV.
Connecting the Switch Wrench to a Programmable Logic Controller (PLC)
A special cable, ordered separately, is required to attach these tools to a PLC. This cable has a threaded con-
nector for the switch wrench and it has bare wires for attaching to the PLC I/O connections. Attach the cable to
the I/O connections, then attach the cable to the switch wrench.
Servicing the Switch Assembly - Necessary Tools
To perform any service on the switch mechanism the fol-
lowing tools will be needed:
1. One hex key, 1/16”.
2. One hex key, 0.050”
3. One flat tip screwdriver, with 1/8” wide blade

1. Box Lid
2. Threaded Connector
3. Chassis Plate
4. Tapped Screw Hole
5. Trigger Set Screw (P/N 890002)
6. Microswitch Trigger
7. Microswitch (P/N 811142)

Servicing Procedures
Box Lid Removal
1. Use the 1/8” flat tip screwdriver to remove the four machine screws (P/N 890011) holding the Box Lid in
place.
2. Carefully remove the Box Lid. This will leave the internal components accessible as shown in photograph
above.
Microswitch Replacement
1. To remove the Microswitch, use the 0.050” hex key to loosen and remove the Microswitch Mounting Screws.
2. Lift the Microswitch off the Chassis Plate.
3. Disconnect the wires.
4. Connect the wires to the new Microswitch.
5. Position the Microswitch as shown in the photograph above and install the two Microswitch Mounting
Screws.
