manner.

A Spring bolt
B Upper screw M12
Person 1: Take a grip of the spring bolt with a
27 mm wrench (extended shaft) and be pre-
pared to hold against the spring force.
Person 2: Loosen the
upper screw (M12) , with
a 18 mm standard wrench approximately 10-
15 mm.
Note
The spring force will probably not be released
until when the upper screw is tapped down in
the next step, but it is a good idea to be pre-
pared to hold against the force already in this
step.
