Examples for Determining the Impact Duration (GDS 30)
Screw/bolt size M 24 of property class 8.8 = Screw/bolt tight-
ening torque 650 Nm
For 650 Nm, the GDS 30 diagram reveals an impact duration
of 0.8 seconds. (Diagram for GDS 30 see page 13)
Tips
Torque rods have shanks with precisely calibrated, reduced
diameters. Thus, they act torque-limiting. A torque rod is
placed between the impact wrench and the bit.
Rule of thumb for the application: Core diameter of the
screw/bolt = effective diameter of the torque rod. The impact
duration is to be determined through practical testing.
For hanging up, a suspension hook 1 is mounted at the ma-
chine's centre of gravity.
The position of the handle can be changed with an angle piece
(accessory).
At temperatures below the freezing point, run the machine for
approx. 3 minutes at no-load to improve its lubricating capac-
ity.
