CAM ADJUSTMENTS
CAM ORIENTATION:
On cams with orientation marks, a reference mark is found to indicate an approximate
orientation. This line is for reference only and is meant to give approximate orientation only
and may vary between bow models. The orientation of the cams may be changed slightly by
twisting or untwisting the string or cable. If attaching the string to the “+” or the “-“ post,
the orientation marks will not be aligned with the cable.
DRAW LENGTH:
ALL MODULAR CAMS (EXCEPT SU CAM)
To change the draw length in 1” increments, the module must be changed. See your local
PSE dealer for information on how to obtain a replacement module. NOTE: some modules
can be changed without a bowpress. Top and bottom modules must be the same size
designation (the physical size may vary) and draw stop position must correspond.
For minor changes in draw length, the bow must be placed in a suitable bow press and
tension relieved from the string and cable. The string side of the cam may have additional
posts. Moving the string from the post with the dot to the post with the “+” will increase
draw by approximately ¼”. Moving the string from the post with the dot to the post with
the “-“ will decrease draw by approximately ¼”.
ALL INNER CAMS:
This system allows draw length adjustments over a prescribed range without putting the
bow in a bowpress. In all cases, the "A" setting is the longest draw length for that bow
and draw lengths get shorter as you progress up the alphabet (A to B, B to C, etc.) When
adjusting the inner cam on a two-cam bow or hybrid cam bow, both cams must be set in
the same letter position. In cases where there is a separate draw stop, the draw stop must
be moved to the hole marked with the corresponding letter as the inner cam setting.
STOP ADJUSTMENTS:
DRAW STOP:
The position of the draw stop must match the size of the module. For example, if the cam
is equipped with a number 7 module the draw stop must be placed in one of the draw stop
holes marked with a “7”. If the inner cam is in the “B” stop, the stop must be in “B”.
LET-OFF:
Let-off adjustment is part of the draw stop. To adjust from higher to lower let-off, remove
the draw stop from the higher let-off hole and reinstall it in the lower let-off hole
of the corresponding module number. For example, if the cam is equipped with a
number 7 module the stop must be reinstalled in the hole marked “7” in the row
marked with the lower let-off setting. Changing to lower let-off will shorten the draw
length a small amount.
STAGE 3™:
DRAW LENGTH: The draw length is adjusted by placing the bow in an appropriate bow
press and relieving the tension from the string and cables. Move the string to the slot that
will shorten the effective length of the string to shorten the draw length by ½” per wheel.
Move the string to the slot that will lengthen the effective length of the string to lengthen
the draw of the bow by ½” per wheel.
