8.3.2
ASSEMBLY
Before fitting the new safety system, clean the holes and grease
the safety pin.
Insert the spring and then the safety pin in the correct position
in the hole on the side.
Hold the safety pin so that the guide groove for the ball aligns
with the threaded hole.
Now insert the ball followed by the threaded pin into the
threaded hole.
Screw in the threaded pin only so far that the moving ability of
the safety pin is not restricted.
Check the function of the safety pin by pressing it in several
times. This must move smoothly and of its own accord into the
locking position.
The threaded pin should be secured against unintentional
unscrewing by a threadlocker or sealing wax.
