PIVOT BLOCK ADJUSTMENT
(AVAILABLE ON FORMULA EXCEL, HORIZON AND EXCEL RISERS)
Most Hoyt riser and limb combinations do not require adjustment. The riser dovetail pocket is
factory aligned and should only be adjusted by a qualified equipment technician. One full sweep
of the block to the left or right will result in a corresponding .020” of lateral limb adjustment at
the dovetail.
Attention: Remove the left & right locking screws (see photo below) before making any ad-
justments. Do not lose the locking screws. Adjustments may be made with the bow in a strung
position, however, Hoyt recommends unstringing the bow to reduce wear on the paint finish
of the limbs.
Do not attempt to adjust or remove the cen-
ter pivot bolt on the alignment block.
With the locking screws removed, access the
adjustment screws to make adjustments:
• Removing turns from the right side screw
and adding an equal number of turns to the
left side screw (viewed from the face or ar-
cher side of the riser) will move the limb tip
to the LEFT.
• Removing turns from the left side screw
and adding an equal number of turns to the
right sidescrew (viewed from the face or ar-
cher side of the riser) will move the limb tip
to the RIGHT.
• Once the proper alignment is achieved, you should snug BOTH alignment bolts against the
dovetail block to the tightened position. Then, replace the locking screws and snug them tightly.
Adjustments can be made to the string to adjust brace height. Adding twists will increase the
brace height while removing twist will decrease the brace height. Generally, Hoyt does not recom-
mend less than 10 twists in a string. Optimum brace height is one that gives a smooth bow action,
good arrow flight, tight grouping and often yields the quietest shot.
ADJUSTING WEIGHT
I
WARNING: Never loosen your limb weight adjustment bolts (Tiller
Bolts) more than 6 turns from the bottomed-out position as it could
cause the bow to violently disassemble
Hoyt Recurve bows are adjustable over a range of approximately 10%.
Factors which affect this include limb length, limb construction, limb
design and brace height.
1. Unstring the bow using an appropriate recurve bow stringer (see pg. 9).
2. Using the longer of the two supplied Allen wrenches; loosen the tiller
bolt locking screw (see instructions on pg. 6). If you plan to increase
weight you will need to loosen this screw by more turns than you plan to
add to the tiller screw.
3. Turn the weight/tiller adjustment bolt clockwise to increase bow
weight. Turn it counter-clockwise to decrease bow weight.
