Impact duration (figure 14).
An unnecessary long impact period increases
the wear of the power tool.
Determine the impact duration for the
respective screwdriving application and check
the actually reached tightening torque with a
torque wrench.
Orientation values for the impact duration are
shown in the diagram.
Recommendation for adjustment of the
impact wrench:
ASCD18-1000W34 (**):When using a 3/4 in to
1/2 in drive adapter, operate the drive impact
wrench maximal at level 3 (600 Nm).
