AmPro tools are manufactured by Frenway Products. Frenway has been in business since 1984 and provides tools and services to 63 countries around the world. Using an AmPro torque wrench allows you to set your own torque specifications for your chosen project. Torque settings are very important when you are working with different engine bolts. If you use too much torque on certain bolts, you may break them and make it harder, if not impossible, to remove from the hole. Always check your bolt torque specifications before you set your torque wrench.

Instructions

1

Hold your AmPro wrench in one hand. With the other hand, grab the locking knob at the end of the torque wrench and turn it counterclockwise to unlock the torque setting.

2

Adjust the handle to your desired torque setting. Start by rotating the handle so the setting reads "0" on the minor graduation scale. The "0" is also in line with vertical scale on the shaft. Both of these scales are in inch pounds (in/lb).

3

Raise or lower the handle to adjust the vertical scale setting. The vertical scale has large numbers (120, 360, 600, etc.) listed in a vertical fashion on the handle.

4

Rotate the handle to your desired setting on the minor graduation scale. This adjustment allows you to add small amounts of torque to your vertical scale setting. "1" on the minor graduation indicates 1 foot/lb and is equal to 12 inch/lb. For example, if you raise the handle on the vertical scale to 360 inch/lb and then rotate the minor scale to "2", you will be adding 24 inches to your 360 setting to make it a setting of 384 inch/lb.

5

Rotate the locking knob clockwise to secure your setting into place.
