Setting
the torque on S/R micrometer adjustable torque wrenches has
three basic steps:
- Unlocking
the grip.
- Setting
the torque.
- Locking
the grip.
In this demonstration the wrench will start at 30 foot
pounds. We will change the torque to 53 foot pounds.
Step
1.
A. Grasp
the rubber grip so the lock is visible.
B. While holding
the grip steady, rotate the lock clockwise (right) to unlock
the grip. The grip is unlocked when the lock moves without
resistance.

Step
2.
A. Hold
the wrench so the scale is visible.
Check the current torque setting.
The current setting is the sum of the major scale setting
and the minor scale setting.
In this image, the number on the minor scale aligned with
the centerline of the major scale is 0. The lowest visible
number on the major scale is 30.
Major scale = 30
Minor scale = 0
Torque Setting = 30
B. Rotate the
grip clockwise (right) to the major scale number of the
desired torque. This is achieved when the 0 on the minor
scale is aligned with the centerline of the major scale
and the major scale number component of the desired torque
is visible.
Note: If desired torque is lower than the current torque,
the direction of rotation is counter-clockwise. The current
torque remains the sum of the major scale number and the
minor scale number.
C. Rotate the
grip further clockwise until the minor scale component of
the number is aligned with the centerline of the major scale.
