SLO Insulated Wrenches
- For use on electrical systems up to 50 volts.
- Reduces possibility of shorting or shock.
- PVC heat shrink insulation.
- May be used for torque on battery terminals.
Calibrating Torque Wrenches
To calibrate torque wrenches either use a torque analyzer or torque transducer
within the range of the torque wrench. For click wrenches calibrate torque in “First Peak” mode with a digital analyzer or
transducer. Make sure to apply the torque slowly and smoothly at the “Load Point Line” near end of the handle.
1. Select a torque analyzer or transducer that covers the torque range of the wrench. Connect wrench to the torque
analyzer or transducer using the appropriate adapters as needed (not supplied).
2. Apply torque clockwise slowly until wrench ‘clicks’ and note reading.
3. Adjust wrench to required torque setting as described below.
4. Test and repeat adjustment as necessary to obtain desired value.
5. Recalibrate torque wrench at prescribed intervals.
Adjusting Torque Setting
1. Use the adjustment knob to change torque setting.
2. Swing lever clockwise to increase torque or counterclockwise to
decrease torque.
Applying Torque
1. Toward the end of the wrench is the “Load Point Line.” Grab handle at that “Load Point” end to apply torque. (If you the
grab handle closer toward head, then you will apply more torque than what the wrench is set for. The wrench is a length
dependent tool).
2. Tighten nut or bolt by applying a steady even pull using built in ratchet as necessary. Wrench should be kept at 90
degrees to axis of bolt during tightening. When pre-set torque is reached, the wrench will ‘click.’
3. After the “click”, do not apply any more torque or you will over tighten it.
Note:
- Best protection for the operator is using an insulated socket with the wrench.
- For operator protection, red insulation is underneath the yellow insulation. Once the red is visible, remove for service.
