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)
