TEMPERATURE WARNINGS

When the torque wrench is exposed to

temperatures below 64°F and above 82°F, or high

levels of humidity (above 90%), it may cause

inaccurate torque settings.

ALWAYS check the torque wrench with an

approved torque tester before and during use in

these conditions.

The torque wrench is designed to tighten bolts and

nuts to a specific tightening or torque specification.

Take the following safety precautions to prevent

injuries and damage caused by improper handling

and unsafe use of the torque wrench:

 NEVER use the torque wrench for loosening

bolts and nuts.

 NEVER use a damaged torque wrench.

 NEVER modify any parts of the torque

wrench or accessory parts.

 NEVER use a torque wrench or an

accessory part that has been modified.

 ALWAYS inspect the torque wrench,

especially the square drive and the

housing, for damage before use.

 ALWAYS release the torque wrench

IMMEDIATELY after you hear the click

indicating that you have reached the

desired torque setting.

 ALWAYS use the torque wrench ONLY in

the direction of rotation indicated on the

housing.

 ALWAYS use only original accessory parts or

parts approved by the manufacturer.

 ALWAYS reset the torque wrench to the

lowest setting after each use or at the end

of the workday.

 ALWAYS hold the torque wrench in the

center of the handle when using the tool

accessories.

Setting the Torque

ALWAYS make sure that you use the scale with the

requisite unit. Non-compliance of the requisite scale

can result in faulty screw connections. These might

cause damage, SERIOUS INJURY or DEATH

Familiarize yourself with the torque wrench and its

scales. The torque wrenches are equipped with a

double scale (N∙m / lbf∙ft or lbf∙in). Check the unit

and scale required.
