Example for determining the impact duration (GDS 30)
Bolt M 24 with property class 8.8 = bolt tightening torque of
650 Nm
From the diagram for GDS 30, 650 Nm results in an impact
duration of 0.8 seconds (see "Diagram for GDS 30",
page 13).
Tips
Torsion bars have a shank with a precisely calibrated, re-
duced diameter. This means that they limit the torque. A tor-
sion bar is slotted between the impact driver and the bit.
As a rule of thumb for application, the following applies:
Core diameter of the screw = effective diameter of the tor-
sion bar. The impact duration is to be determined through
test screw applications.
A suspension eye (1) is attached to the power tool's centre
of gravity so it can be hung up.
You can use an elbow (accessory) to change the position of
the handle.
At sub-zero temperatures, the power tool should first be op-
erated at no load for approx. three minutes to improve the
lubrication performance in the power tool.
