USER’S GUIDE

CAM ADJUSTMENTS

WHEELS/CAMS:

Many PSE wheels and cams have adjustable features. Each one comes from

the factory set up and ready to use but there may be occasions that you need to adjust the

characteristics of your bow. In some cases you will need a PSE Tune Chart to determine what

to adjust, and you may need to see a PSE Dealer for information. If you are not sure of the

adjustment you are making, stop and see your PSE Dealer for assistance. In some cases, an

appropriate bow press will be needed to make adjustments to cams and wheels. If you do not

have an appropriate press, see your PSE Dealer.

CAM ORIENTATION:

On cams with orientation marks, a reference mark is found to indicate an approximate

orientation. This line is for reference only 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 cables.

ALL INNER-CAMS:

The inner-cam system allows draw length adjustments over a prescribed range usually without

putting the bow in a bow press. There are two types of inner-cam systems: discrete setting

inner-cams and Posi-Lock inner-cams.

Discrete setting inner-cams have the adjustment screws going through a specific hole in the

inner-cam and threading into the cam. The screws need to be completely removed to make

adjustments. The “A” setting is the longest draw length for that bow and draw lengths get

shorter as you progress through the alphabet (A to B, B to C, etc.)

Posi-lock adjustable inner-cams are adjustable in ½” draw length increments. The “A” setting is

the longest setting for the cam. Draw lengths get shorter as you progress through the alphabet

(“A” to “B”, “B” to “C”, etc.) by roughly ½” per letter.

Second and third generation Posi-lock inner-cams

allow for draw length adjustments in ½” increments

without changing inner-cams. To adjust draw length,

loosen the two 8-32 button head screws two full

turns. This will allow the inner-cam to be lifted far

enough to disengage the positioning pin and allow

the inner-cam to rotate to a new position. Some

cams may require the 8-32 button head screws to

move to alternate locations to reach the new draw

length adjustment position. Some draw length

adjustment positions may not be accessible without

putting the bow in a bow press. When the new

draw length adjustment position has been achieved

with the inner-cam, tighten the two 8-32 button

head screws and move the draw stop to the

matching setting (“A” and “A”, “B” and “B”).

In cases where there is an inner-cam on both the top and bottom cam, both cams must be

set in the same letter position for the bow to tune and shoot properly. In cases where there

is a separate draw stop, the draw stop must be moved to the hole marked with the letter

corresponding to the inner-cam setting.
