BASIC SETUP Your new Martin bow takes little setup to get started shooting. Please read and familiarize yourself with these starting procedures before shooting. Many of these procedures will have been completed by your authorized Martin dealer. After completing these simple steps, you will be more accurate and will have greater success from the start. A careful and thorough initial setup will make the tuning process much easier. CABLE GUARD INSTALLATION All Martin compound bow models* feature smooth bore holes in the riser that allow direct, bracket-free installation of the cable guard rod. There are set screws within the riser that will secure the rod. The cable guard rod should be rotated toward the grip to provide adequate fletching clearance. Caution should be taken against over-rotating the rod as excessive clearance can cause unnecessary pressures on the limb tips and axle bushings. Only 9/16” offset is necessary to provide adequate fletching clearance. Though most bow models allow either an upper (above the arrow rest) or lower (below the grip) mounting, Martin Archery recommends the upper mounting position on all Fuzion single cam models. *As of this writing, the Scepter II and Rage models did not allow the direct installation of a cable guard rod. A mounting bracket is supplied with these models that threads into the threaded holes provided in the back of the riser. SETTING DRAW LENGTH Z Cams and Mini Z Cams The Z Cam uses draw length modules to adjust the draw length. The size of each module is designated by a number followed by an 'X'. These modules are sized from 2X to 9X. The 9X makes the longest draw and the length decreases one inch for each number. To change the draw length on these cams, simply remove the two screws holding the module to the cam. Take a look at the module number and select a new module that will give you the correct draw length. Install the new modules, making sure that the numbers on each module match. NOTE: Do not draw your bow without the modules installed. It will cause damage to your harness system. Cable Guard 6
Fury Cams & Fury X The Fury Cam is a draw length specific cam. Each cam was designed to give peak performance and speed at each specific draw length. Therefore, changing the draw length requires changing to a different size cam. Fuzion Single Cam System A full explanation on the Fuzion Cam System, including changing the draw length, can be found on page 10 and 11. CHANGING DRAW WEIGHT Martin bows have a fifteen pound draw weight range. Using the 3/16” Allen wrench supplied with each bow, you will turn the limb bolts clockwise to add weight and turn counter clockwise to reduce weight. One complete turn on each limb bolt provides about 4 pounds of adjustment. TIP: Mark a line on each limb bolt in white-out or white paint marker to make it easier to keep track of how far you are turning each bolt. NOTE: Do not shoot your bow with the limb bolts more than 5 turns out from the riser. SETTING TILLER After setting the draw weight on your bow, you will need to set the tiller measurement to make sure that you have adjusted your limbs properly. On all Martin compound bows, “0” tiller will shoot perfectly. However, the tiller measurement can vary up to 1/4” closer at the bottom. There is no set measurement that provides peak performance for every shooter. To measure your tiller, simply measure from the limb pockets to the string on both ends of the bow (see Fig.1). You can custom fit the feel of your bow by experimenting with the tiller setting. Start with even tiller, when both top and bottom limbs are adjusted the same. (Before adjusting your limb bolts, mark a white line from the center of the limb bolt to the outside. This will help you keep track of your settings.) By tightening one bolt a quarter turn at a time you will begin to affect the steadiness of your setup. If the bow begins to become unsteady, move the tiller back to even and tighten the opposite limb bolt. After finding the best spot, make a note so if you ever change the draw weight you can reset the tune where you had it shooting best (i.e., 3/4 bottom would mean three quarters of a turn on the bottom limb bolt). NOTE: Your peep sight position and your nock point will change as you turn one limb bolt. Take measurements and correct your nock and peep each time you turn your bolts. 7 Fig.1
