2. Using a bow stringer,
unstring the bow and dismount
the limbs.
3. Before adjusting the Hardlock
dowels on the Helix/Nexus, note
the relationship of the dowel
and slot to the riser. This is the
factory zero point and by using
it during reassembly, you will find it quick and easy to re-set
the dowel to the factory radial settings. (You may use a paint
pen or pencil to mark dowel settings).
4. In order to make a riser alignment adjustment, you will need
to use the two included Allen wrenches. Engage the hex
head broaches on both ends of the dowel (one of which is a
locking screw) and twist the lock screw counter-clockwise to
loosen the system. Note that under the washer that engages
this screw, there will be several brass alignment washers. A
factory-shipped riser will have two but if the riser has been
adjusted the number may vary.
5. Helix/Nexus hardware dow-
els have a radial locking feature
which prevents dowel rotation,
even under severe dry-fire con-
ditions. The next step in adjust-
ing the Helix Hardlock system
is to loosen the radial locking
screw by two complete turns
(as shown in figure to right).
Once the radial screw is loose, the entire dowel assembly
will easily slide out of the riser. Be certain to always install
the dowel from the sight window side, as the dowel is asym-
metrical and designed to mate with the recessed area on the
sight window side of the riser.
6. Refer to the condition chart on page 12. If your limb is
showing Condition A, add washers to the sight window

side of the alignment dowel. If your limb shows condition
B, remove washers from the sight window side and shuffle
them to the opposite side during re-assembly. Note that only
washers on the sight window side control the alignment, so
you can store unused washers on the non-sight window side
without affecting any settings.
7. Reassembly is accomplished by inserting the dowel into the
sight window side of the riser, and aligning the dowel radially
as shown in the figures on page 8. Then, snugly lock the radial
set screw to pin the dowel in place. Re-install any leftover
washers and the alignment cap, then using the two supplied
Allen wrenches; complete the reassembly by re-installing the
dowel cap washer and lock screw. Tighten snugly.
8. Re-check all locking screws for tightness and reassemble
the bow.
ECLIPSE ALIGNMENT:
Tiller and weight adjustments for the Eclipse follow the same
directions as those for the Helix and Nexus. The Hardlock
dovetail limb mounting system on the Eclipse is factory pre-
set and is not user adjustable.
ADJUSTING BRACE HEIGHT (“FISTMELE”)
Brace height, or “fistmele,” is the perpendicular distance from
the bowstring to the pivot point of the handle. This height is
an important aspect of tuning. The following chart gives you
the recommended brace height range for your Hoyt recurve
bow. (See chart on page 10)
