DRAW LENGTH ADJUSTMENT (INNER-CAM
ADJUSTABLE MODULES)
Many Hoyt bows utilize the inner-cam adjustable
module for draw length adjustment. The inner-cam
can generally be adjusted without the aid of a bow
press.
CAM & 1/2 DRAW LENGTH ADJUSTMENT
TOP CAM:
To adjust the draw length on Hoyt’s Cam
& 1/2 (inner-cam) model bows, use a standard allen
key to loosen the fastening screw and to remove the
draw length screw. Rotating the inner-cam
in the (+) direction will lengthen the draw. Rotating
the inner-cam in the (-) direction will shorten the
draw. Each lettered position will provide approximately l/2 inch longer/shorter draw than the previous setting. Once the innercam is in the desired location, reinstall and tighten the draw length screw first and then the fastening screw.
BOTTOM CAM:
Remove the draw length screw,
rotate module to the same lettered position as the top
module, and replace.
Note: You must
make the same adjustments to the top and the bottom
inner-cams or the bow will not tune properly.
WARNING:
N e v e r remove the s t a i n l e s s steel control cable peg unless the string is relaxed in a bow press.
