7-2. Tightening Torque Inspection Prior to Operation

The output tightening torque of the Model WR 22SA is higher than the rated tightening torque of certain bolts.
Accordingly, if the tightening time is prolonged for such bolts, it could cause damage to their threads or, in the
worst case, cause them to be sheared off. (This phenomenon is common to all existing impact wrenches.)
The customer should be advised to carry out several bolt tightening operations and adjust the tightening time as
necessary by measuring the tightening torque before commencing continuous operation.
