WHEEL TIMING (FOR TWO CAM SYSTEMS)It is important for consistency and accuracy that your bow’s cams “roll over” atthe same instant and are in the same position when you are at full draw. Your camsshould be synchronized or “timed” to your particular style of shooting. To check thetiming, draw your bow with your fingers or release just as you would while shooting.Different drawing methods will affect the roll over of your cams. Draw the bow usingyour exact shooting method.Cams are in perfecttime.Upper Cam isover-rotated andout of sync withthe bottom camAdjust this yokeby twisting upthe bottom SplitString cable.Adjusting timing using the Split String System (synthetic cables)This procedure can be expertly performed by yourString Anchorlocal archery professional. You will need a bow pressor a bow stringer to adjust your timing using the SplitString System. First, determine which cam is ahead, orout of sync. The Split Strings, or buss cables, shouldSplitreach the end of the cable grooves on the PowerStringSide (back side) of each cam at the same time. Then,while the bow is relaxed, remove the appropriate SplitString off its outside posts and twist in a directionthat shortens or tightens the cable. A few turns willgo a long way so proceed sparingly. If your top cam isahead, or rotates further than your bottom cam, twistthe bottom Split String, do the opposite if the bottomwheel is ahead. After these steps are completed makesure that all of your string loops are firmly secured ontheir appropriate pegs before the pressure is reappliedto the bow.NOTE: Back your bow limbs out five turns from the riser before using a bow stringeror a bow press. Only let a qualified professional put your bow in a bow press.8
