1. INTRODUCTION
The mini torque wrenches listed in Figure 1 are used to properly install or disassemble the described
connectors.
Figure 1 also lists the previous part numbers of the wrenches, description and size, and preset torque for each
wrench.
NOTE
All numerical values in this instruction sheet are in U.S. customary units. Dimensions are in metric units [with U.S. customary
units in brackets]. Figures and illustrations are for reference only and are not drawn to scale.
Reasons for reissue of this instruction sheet are provided in Section 5, REVISION SUMMARY.
2. DESCRIPTION
Each mini torque wrench consists of a protective cover, torque wrench, and a “fillister head” screw (which
permits replacement or change of various wrench heads).
Type A wrench is equipped with an open-end head, and Type B wrench is equipped with a partially- closed
socket head and extension arm. Refer to Figure 2 for head and extension arm replacement part numbers.
The wrenches are designed to be used in the clockwise or counterclockwise direction.

3. OPERATION
NOTE
If a wrench has not been used recently, move the head back and forth several times, listening for audible “clicks”. Moving the
head back and forth spreads lubricant throughout the internal mechanism to improve wrench performance.
Using the appropriate-sized head (refer to Figure 1), and turn the wrench clockwise or counterclockwise until
there is an audible “click”. This “click” indicates that the torque has been achieved.
CAUTION
DO NOT over-tighten the connector with the wrench. Over-tightening could result in inaccurate torque settings.
4. REPLACEMENT (Refer To Figure 3)
Type “A” heads are interchangeable. Remove the screw securing the head to the wrench. Remove the head.
Then install the appropriate head listed in Figure 2.
Type “B” heads are replaceable. Remove the screw securing the head and extension arm to the wrench.
Remove the head and extension arm. Break the press fit between the head and extension arm. Replace the
components in the reverse order of removal. See Figure 2 for replacement parts.
