If the torque wrench runs roughly, it should be lubricated with silicone
grease (Mat. no. 1.000.6403). The silicone grease is pressed into the tor‐
que wrench in the slots or grease pockets of the locking springs. Then place
a small amount of grease on your fingertip, and press it into the torque
wrench at the indicated location (see arrow). Then rotate the torque wrench
and regrease if necessary.
