    ACUdraw 50 Cord Installation

    TenPoint part number HCA-450 (ACUdraw 50 Draw Cords) is required. Do not attempt to use any other cord or material.

    1. Remove the two Phillips-head machine screws from each ACUdraw 50 cover, and then remove the covers.

    2. Pull both ACUdraw 50 hooks and handles all the way out and attach one of the hooks to the crossbow string.

    Note: Keep at least one hook attached to the bow string to prevent the power spring from unwinding. If the power spring has already unwound, you will need to remove both sets of hooks, handles and cords from the unit prior to re-winding the spring (see ACUdraw 50 Power Spring Installation step # 10).

    3. Cut the draw cord that is not attached to the crossbow string (normally you cannot reuse the draw cord once it has been cut). Remove the hook and handle from the cord and remove the cord and knot that is still inside the axle.

    1. Tie a knot in one end of the new draw cord. Insert the unknotted end into the top of the draw handle and then into the brass pulley on the hook (hook facing up and pointing to the front of the crossbow). Note: Insert the cord into the hook from the left side when working on the left side of the unit and insert the cord from the right side when working on the right side of the unit.

    2. Thread the cord through the large hole (non-countersunk) in the axle and tie a knot at the end. Pull the knotted end into the axle’s counter-sunk hole until the knot is fully seated inside the hole.

    3. Making sure that the draw cord exits under the silver guidepost at the front of the mechanism, extend the cord and attach the hook to the bowstring (underneath the string with the open end of the hook facing up).

    4. Remove the draw cord from the opposite side of the ACUdraw 50 unit then repeat steps 3-6.

    5. Count the number of cord wraps on each side of the unit – make sure there is the same amount of wraps on each side. You will have to thread the cord under the silver guide post each time you make a wrap (loosening the Phillips-head screw in the silver guidepost will help when adding cord wraps then make sure you tighten the screw again when finished).

    6. Check to make sure the draw-cords are equal in length. If they are not, re-tie the knot in one or both of the handles until the cords are even.

    7. Once you are certain you do not need to modify the length of either of the draw-cords, you can clip the tail off the knots imbedded in the grip handles. Using a lighter or a match, burn the end of the cord until it forms a molten ball. Press the flat side of a butter knife blade against the ball to compress its surface and seal the knot. Pull the knot back into the recessed hole in the grip handle.

    8. Remove both hooks from the string and work the cords forward and backward several times, making sure the axle is spinning freely (if the unit begins to bind, refer to the ACUdraw 50 Troubleshooting section).

    9. Replace the hooks on the bowstring and re-attach the ACUdraw 50 covers and screws. Note: Inserting the rear cover screw first, loosely, will assist you with lining up the front screw in its proper position.

    10. Remove the hooks from the bowstring and let the retraction spring draw the hooks inside the covers. They will fit perfectly inside the covers if you turn their open ends outward (only the part of the hook with the brass pulley is inserted into the cover).
