With the handbrake fully off, check that the spring store’s overall
length is 185 to 190 mm and is not applying a force to the U
shaped guide on the side of the overrun lever. Adjusting is by the
nut at the front of the assembly. This procedure should only be
necessary when replacement parts have been fitted.

The setup for the higher capacity couplings is similar to the above,
with the exception of the setting of the handbrake spring store,
which is more powerful due to the higher transmission force
requirements for heavier trailers.
Use the plain nuts behind the compensator to adjust, until the
overrun output lever can be pulled rearwards by firm hand
pressure to a maximum of 18mm (8mm for adjustable height
models).
Maintain the compensator at 90° to the drawbar for even
distribution of force into each cable. Ensure the cables are not
“kinked” or damaged.

Leave the handbrake and spring store connector loose while
setting the overrun system as previously described. Finally, pull
the spring store up to the hexagonal adaptor by sliding the spring
and bracket forward. Tighten the three locking nuts on the
connector.
With these models, the brake transmission linkage runs through
the spring store, which must be set correctly to achieve automatic
operation tensioning of the system.
