1 Tips for Preventing Damage
4 Use a torque wrench to make final connection. Tighten until the
“break” point of the torque wrench is reached. Do not push beyond
initial break point. Use additional wrench, if needed, to prevent device
body from turning.
Using the torque wrench
• Hold the torque wrench lightly, at the end of the handle only (beyond
the groove).
• Apply downward force perpendicular to the wrench handle. This applies
torque to the connection through the wrench. Do not hold the wrench
so tightly that you push the handle straight down along its length
rather than pivoting it, otherwise you apply an unknown amount of
torque.
• You don’t have to fully break the handle of the torque wrench to reach
the specified torque; doing so can cause the handle to kick back and
loosen the connection. Any give at all in the handle is sufficient torque.
• Tighten the connection just to the torque wrench break point. The
wrench handle gives way at its internal pivot point as shown in the
figure. Do not tighten the connection further.
• Follow the torque wrench information listed in the following table:
