How to Replace a Bow String on a Parker Hunter Mag

The Hunter Mag is a compound bow made by Parker Bows. A compound bow features a string under immense tension which draws smoothly with the help of two cam pulleys. The pressure of the strings gives a compound bow its unrelenting power and range. Since the strings are under so much pressure, they're subject to wear and require annual replacement. If a worn string snaps while on the bow it could cause serious injury to the marksman. Replacing the string on a Parker compound bow is integral to keeping the bow safe to operate, and is relatively straightforward.

Instructions

    • 1

      Place the bow into a bow press with the strings facing up. Loosen the bow's two bottom pins, found where the riser and limbs meet, with an 3/16-inch Allen key.

    • 2

      Turn the lower adjustment screw on the bow press clockwise to tighten the bow press and relieve string tension. Continue to tighten the bow press until you can easily wrap the bow retaining bands around the bow press limbs.

    • 3

      Adjust the left side pin so that it connects with the bow's limb, roughly 1/2 inch below the cam, and attach the side bar to the piston. Repeat this adjustment on the right side pin. The adjustments must be symmetric.

    • 4

      Turn the bow press crank clockwise until the strings sag. Remove the string from the holding pin on both cams and pull the string away from the bow.

    • 5

      Fit one end of the new string on a cam pin and wrap the string around the bottom cam. Confirm that the string is resting in the cam's groove.

    • 6

      Pull the loose end of the string tight, wrap it around the top cam and secure the end to the top cam pin. Confirm that the string rests in the grooves of both cams comfortably.

      Slowly turn the bow press crank counterclockwise to gradually apply tension to the new string. Remove the bow from the bow press.
