safety clutch which starts to slip for a short-
time immediately after the drilling tool is
jammed. It protects the user from injury
due to the return stroke.
9.2 Antivibration extras for the
device
The device is equipped by antivibration
components, e.g. the main sprung handle
[1-9] and by the soft and fl exible grip part
of the extension handle, damping the vi-
brations transferred from the device to the
operator effectively.
