place by inserting its bolt, from the top, through the
Tool and through the Carrier Bracket. Fix with its nut
from underneath - tighten nut.

sides of the Tool, The Safety Pin will restrict the
torsion spring's movement backwards under tension,
when the spring retaining screw is removed.
Slowly unscrew and remove the torsion spring
retaining screw (Tx30) so that the spring plate pushes
against the Safety Pin.
Using a suitable pair of
adjustable pliers fit the
jaws to span across from
the back of tool to the
front of the torsion spring
plate.
Carefully relieve the
spring pressure off the
Safety Pin by slightly
closing the Plier jaws
and whilst retaining the
jaws in this position, pull
out the Safety Pin.
Carefully and slowly, in a
controlled manner, allow
the Plier jaws to open in
order to release the
torsion spring pressure
fully.

spring together with the
associated D818 Clamp
and intermediate
lever.(Remember to
identify the position of
the lever)
