Proper use of torque wrench
Check the setting of the wrench before use.
Make sure that the proper measurement unit (kgf􀉾cm, kgf􀉾m, N􀉾m Ibf􀉾in, etc.) is used in setting the wrench.
Avoid submersion in water. Water will cause damage to internal components and ruin the wrench.
Only use a socket in the proper hex size for the bolt being tightened.
The torque wrench handle has an effectivelength mark, which must be used to grip it in the proper place. Improper grip position will reduce accuracy.
A click will signal that the proper amount of torque has been applied. Pay careful attention, and stop tightening when the click is heard or felt.
Use the torque wrench only where there is sufficient clearance and freedom of movement. You may select another wrench, if necessary.
Never use the torque wrench as a hammer or mallet.
Have the torque wrench inspected periodically by someone qualified for that purpose to insure accuracy and proper functioning. Torque wrenches are required periodical inspection.
The loading direction must be at a right angle to the torque wrench. The tolerance is plus/minus 15 degrees of horizontal or vertical deviation. See fig. Before using or storing the wrench, or whenever necessary, remove all debris, oil, water, etc. Keeping the wrench clean will prolong its life.
If the wrench must be stored for long periods, apply rust-proofing oil, and store the wrench in a dry place. Improper storage may cause damage to the wrench, and reduce the accuracy.
