Bosch Professional GHE 18V-60 Original Instructions Manual page 17

To reach a level finish, fasten a piece of string along the
length of the hedge at the required height and use as an
alignment guide. Cut the hedge just above the string.
Pay attention that no objects such as wires are cut. The
blade or drive can be damaged.
Anti Blocking
If the blade stalls on a tough material, the load of the motor
increases. The intelligent micro-electronics senses this over-
load condition and repeatedly reverses the motor, in order
to prevent stalling and to cut the branch through.

This audible reversing cut action continues for up
to 15 rounds when the switch is actuated.
During repeated heavy cutting scenarios, the anti blocking
function could disable for 15 seconds to allow it to reset.
After cutting through, the garden product continues in its
normal mode, or in case the overload condition continues
the blades automatically stop in the open position (e.g. in
case a piece of metal fence accidentally blocks the garden
product).
