TORQUE WRENCH
TW-1 (0 – 60 Inch Pounds/ 0 – 7 Newton Meters)
TW-2 (0 – 600 Inch Pounds/ 0 – 70 Newton Meters)
To prevent over tightening and under tightening of bolts and nuts, specific torque specifications are
provided by most bicycle component manufactures. TW-1 and TW-2 Torque Wrenches accurately
measure the amount of torque (turning or twisting force) being applied to a bolt or nut.
CALIBRATION
The pointer tip of the TW-1 and TW-2 should line up with the "0" on the scale plate. It should also
"float" over the scale plate, without contact. If this is not the case, simply bend the pointer near the
head of the wrench until the pointer tip is in the correct position. Bending the pointer will not damage
the wrench or impact its accuracy.
TORQUE WRENCH USE
1.
Install desired wrench bit (not included) onto square head of torque wrench. The TW-1 accepts
⁄ " drive bits and ⁄ " drive bits (with the included adapter). The TW-2 accepts
1 3
4 8
2.
Place bit and wrench onto bolt or nut to be tightened.
3.
Grasp handle of torque wrench. NOTE: The TW-2 uses a pivoting handle for greater
accuracy. When using the TW-2, grasp handle so that force is balanced at the pivot point
(Figure 1). Accuracy is affected if other parts of the handle contact the beam while in use.
4.
Turn wrench on bolt or nut with steady pressure until tip of pointer reaches the desired torque
on the scale plate. The bolt or nut should be in motion when the final torque reading is made
on the scale plate.

IMPORTANT INFORMATION
.
1 Clean threads and remove burrs from bolts and nuts before assembly. Lubricate threads with
appropriate grease, oil or anti-seize lubricant for proper tightening and accurate torque reading.
Do not lubricate bolts or nuts using a nylon or "Nylok" thread fitting.
.
2 If flexible adapters or crow-foot extensions are used, re-calculate
the needed torque using the formula:
Torque (T) = Force (F) x Distance (D).
.
3 Torque wrenches are precision tools. Store carefully to
avoid damage. Any defacement of the beam will impact
the accuracy of the wrench and result in failure.
