As you may already be aware, the Bladerunner design concept embodies a truly new and unique isometric design based on perfect symmetry and balance. This new design concept totally eliminates all of the problems inherent to asymmetrical conventional compound bow design that results in tuning difficulties.
SET UP AND TUNING YOUR BLADERUNNER BOW AND ARROW SYSTEM FOR OPTIMUM PERFORMANCE:
You will find that the Bladerunner bow is the easiest to tune for deadly precision arrow flight that you have ever encountered. Additionally, you will find that broadheads of any type will fly to the same point as target points. Further, you can shoot virtually any
shaft of any length and at any poundage and easily tune for precision arrow flight.
To Setup and tune:
First install your nock perfectly in the center of the bowstring from top to bottom. (This is critical for optimum performance). An arrow positioning gauge (APG) is furnished with the bow to make vertical and horizontal arrow positioning a snap.
Place the APG on the shelf of the bow so that it exactly fits the radius of the shelf and riser. Place an arrow of the same diameter you will be using through the APG. Nock the arrow and adjust the arrow rest vertically and laterally such that the arrow rests perfectly in the center of the APG. *NOTE* Make sure that the APG is firmly held against the riser* This is easily accomplished by using the slots along the outside of the APG for reference. The bow is now perfectly tuned and will not need any adjustments when changing from field points to broadheads. Of course, it goes without saying that the arrow used must be properly constructed with proper head and nock alignment, a proper front of center balance, and such that there is no fletch contact with the rest.
Bladerunner Cam Timing and Synchronization:
*CAUTION* DO NOT USE A BOWPRESS ON THIS BOW - DOING SO WILL VOID THE WARRANTY
Your Bladerunner bow was set at the factory to achieve optimum performance and proper cam synchronization and should not require
adjustment under normal conditions. Proper cam timing can be easily checked by simply observing the location of the upper and lower
buss cables in relation to the large lobe of each cam. *See Illustration #1*
Each buss cable should cross the adjacent cam lobe, as viewed from the side of the bow, in the same position as the opposing
cable/cam lobe relationship. If there is a significant difference, the following simple adjustment can be performed to return the cams to
proper timing.
First, observe the synchronization spool and cable system located on the string hand side of the bow. Note that each synchronizing spool has an 8-32 locking screw located in a curved slot on the faceplate of the spool. Loosening this screw allows the outer faceplate of the spool to rotate on the spool body to adjust tension in the synchronizing cable. *See Illustration #2* (The lock screws should never be completely removed, only loosened slightly to allow the faceplate to rotate.) are tight, direction (opposite directions) and at the same rate providing positive synchronization. If the screws are loosened slightly to allow rotation of the faceplate at brace, the cams may be rotated in the same directions such that the exact same orientation of each cam can be achieved. Therefore, to adjust the cam timing, loosen one lock screw slightly to allow slight like rotation in the cams; and by rotating the cams by hand, put each cam into the same position in relation to the adjacent buss cable. adjacent synchronization spool faceplate Check for proper orientation of cams and if additional adjustment is required, repeat the procedure on the second cam. Continue to alternate cam adjustment until both cams are equally oriented with all slack removed from the synchronization cable. Normally, only one or two adjustments are required to properly and quickly place the cams into proper time. Do not over-tighten the lock screws. The Bladerunner uses perfect center-shot, isometric and symmetrical geometry; so, drawing the bowstring tends to maintain synchronization as opposed to conventional, asymmetrical geometry that tends to inhibit synchronization. The synchronization system on the Bladerunner only that any slight imbalance of forces imposed by the archer are held in check.
**Once properly set, cam timing and synchronization will remain set under normal use; and your Bladerunner bow will attain optimum
performance. Under normal conditions, it should never “go” out-of-time, even due to string or cable stretch. If for some reason it does get
out-of-time, it is easily checked and easy and quick to adjust. You don?t need a bowpress or need to experiment with twisting strings or
cables to achieve proper timing. That's just another advantage that the Bladerunner provides that other, conventional bows can't.**
Now you are ready to set your sight pin or pins. Your windage adjustment will be perfectly in line with the arrow and the bow string. This
will be a starting set-up for windage. Some slight left or right adjustment may be required according to your eyesight and/or anchor
characteristics. Elevation adjustments will be according to your draw weight, draw length, and arrow weight and length as to the proper
setting(s) relative to the velocity achieved with your particular set-up. You will find all of these settings to be quick and easy.
Some additional advice: Practice as often as you are able; match your arrows as closely as possible, and check your arrows frequently. If you find one of your shots is routinely out of group, it is most likely one arrow that is not matched to the rest of the set. Number your arrows, identify any flyers and either restore them to match the set or discard them. You should find that your Bladerunner, once tuned with best arrows, will stay in tune and if any tweaking is required, it is easy and quick to accomplish (on your own).
Bladerunner Draw Length Adjustment:
The draw length of the Bladerunner is easily changed without a bowpress by using interchangeable cam modules. Standard draw length modules are available for nominal draw lengths of 26, 27, 28, 29, 30 and 31 inches. The modules are easily changed by removing the one 8-32 mounting screw in each module, removing the existing modules from the cams, and replacing with a different draw length module set. Because the Bladerunner is a very compact, short axle-to-axle bow, either some type of string loop and a mechanical release or a
double contact type release is required. You will need to factor the loop length and the type of mechanical release into your draw length requirements.
Replacement of Bladerunner Bowstring and Cables:
Replacement of the bowstring, buss cables or cam cables on your Bladerunner bow is relatively simple and does not require the use of a bowpress. With a few simple tools, you can quickly replace a damaged or worn bowstring or cable at home or in the field. Remember however, that while the Bladerunner bow provides the valuable advantage of allowing for replacement of the bowstring and cables without the need of a bowpress and even in the field if necessary, careful attention to detail is required. Failure to carefully follow the instructions may result in damage to the bow or personal injury if the bowstring or cables are not installed properly. Keep the instructions in your field kit, follow them carefully, paying attention to every detail. Take your time and you can successfully accomplish the task and avoid a trip to the shop. However, if you are uncomfortable in any way working on your bow, take it to your Bladerunner dealer and they will be happy to handle any maintenance required.
Replacing A Bowstring:
1. Note the depth that each limb bolt is threaded into its limb bolt anchor.
2. Use a 3/16” Allen wrench to unscrew limb bolts by alternating between top and bottom limb bolts, one turn at a time until all tension is removed from bowstring.
3. Remove bowstring from grooves in idler wheels at limb tips.
4. Unwind bowstring from groove in take-up spools and unhook each end loop of the bowstring from the anchor lug. *NOTE* The old bowstring is now free from the bow.
5. Wrap one end of the new bowstring onto one take-up spool in the opposite direction that the old string was removed and hook the end loop of the string over the anchor lug. are required to properly and quickly place the cams into proper time. Do not over-tighten the lock
screws. The Bladerunner uses perfect center-shot, isometric and symmetrical geometry; so, drawing the bowstring tends to maintain synchronization as opposed to conventional,
6. Make sure that the free end of the string is routed through the limbs and around the idler wheels and repeat the take-up spool attachment described in step 5 for the opposite end of the bowstring.
7. Carefully inspect the routing of the bowstring and cables to make sure they are properly aligned with the grooves in which they run.
8. Re-tighten the limb bolts, alternating one turn of each bolt at a time, until the original limb bolt settings are obtained.
9. Check again for proper routing of bowstring and cables, then slowly draw the bowstring to check for proper function.
10. Install new nock clips, D-Loop, and peep sight onto the bowstring as required. *NOTE* You may want to install items such as a
peep sight or string silencers that require installation between the strands prior to re-tensioning the string.
Replacing A Buss Cable - 4 1/2”
1. Note the depth that each limb bolt is threaded into its limb bolt anchor.
2. Use a 3/16” Allen wrench to unscrew limb bolts by alternating between top and bottom limb bolts, one turn at a time, until all tension
is removed from the cables and bowstring.
3. Remove the retainer clip from the cable anchor pin on one cam and remove the pin from the cam to free one end of the cable.
4. Remove one retainer clip from the anchor pin located at the bracket arms extending from the idler axle at the limb tips.
5. Remove the pin to free the grooved sleeve from between the bracket arms.
6. Remove the cable loop from the groove in the sleeve. (Note that the loop of the cable that attaches to the sleeve is unserved, while
the opposite loop that attaches to the cam is served.)
7. Install the unserved loop of the new cable around the sleeve and into the groove making sure that the number of strands in the
loop are equal around the groove.
8. Position the sleeve between the bracket arms, insert the pin through the arms and sleeve, and re-install retainer clip into its groove.
9. Position the opposite (served) loop of the cable into the cam groove so that the loop lines up with the holes for the anchor pin.
10.Insert the anchor pin through the cam and the cable loop and re-install the retainer clip into its groove.
11.If required, repeat steps 3-10 to replace buss cable at opposite end of bow.
12.Carefully inspect routing of cables and bowstring to make sure that they are aligned with the grooves in which they run.
13.Re-tighten the limb bolts, alternating one turn or each bolt at a time, until the original limb bolt settings are obtained.
14.Check again for proper routing of cables and bowstring. Then slowly draw the bowstring to check for proper function
Replacing a cam cable: NOTE: Unlike replacement of the bowstring and buss cables, replacement of the cam cables requires partial disassembly of bow components.
1. Note the depth that each limb bolt is threaded into its limb bolt anchor.
2. Use a 3/16” Allen wrench to unscrew limb bolts by alternating between top and bottom limb bolts, one turn at a time, until all tension is removed from the cables and bowstring.
3. Remove the 8-32 screw and washer that secures one end loop of the cable to the major lobe of the cam and remove the cable from the lug and out of the slot in the cam. NOTE: The loop attached to the cam is unserved.
4. Remove one retainer clip from the take-up spool axle and slide the axle out of the bearings in the side plates, freeing the take-up spool.
5. Slide the take-up spool out from between the side plates (toward the center of the riser).
6. Remove the two 6-32 screws that secure the cover plate to the take-up spool.
7. Remove the opposite end loop from the center lug and the slot.
8. Install the new cable into the slot in the take-up spool with the loop around the center lug, making sure that there are an equal number of strands on each side of the lug.
9. Replace the cover plate and secure it to the take-up spool using the two 6-32 screws.
10.Making sure that the new cable is routed around the spool in the same direction as the old cable, slide the take-up spool back into position between the side plates; insert the axle through the bearings and the take-up spool and replace the retainer clip into its groove.
11.Route the free end of the new cable around the groove in the major lobe of the cam, through the slot, and place the loop over the lug
making sure that there are an equal number of strands on each side of the lug.
12.Replace the washer and 8-32 screw over the loop and tighten securely.
13.If required, repeat steps 3-12 to replace cam cable at opposite end of bow.
14.Carefully inspect routing of cables and bowstring to make sure that they are aligned with the grooves in which they run.
15.Re-tighten the limb bolts, alternating one turn of each bolt at a time, until the original limb bolt settings are obtained.
16.Check for proper routing of cables and bowstring. The slowly draw the bowstring to check for proper function.
