setting torque
1. Pull the lock knob out downside. The locking and unlocking directions are indicated by ap-
propriate icons on the lock knob.
2. Turn the grip in the clockwise direction to increase the torque, and in the counterclockwise to
decrease it.
3. The major scales show the amount of torque in both primary and secondary units. The minor
scale shows fine increments in primary units. See examples on the next page.
4. Push the lock knob back to lock the grip. The minor scale may move a small amount to either
side of the centerline mark without affecting the accuracy of your setting.
Use of Extensions
Extensions that put the center of the fastener being tightened away from the centerline of the
ratchet drive, result in the effective torque being different from the one shown on the wrench.
Consequently, the torque set on the wrench must be corrected using the formula shown on the
next page.
