Timing
The timing of the bow is the time it takes to pull the string back fully. The desired timing is achieved when the string is pulled back in one solid motion with a single click. Multiple clicks means a bad timing adjustment. The timing is adjusted by turning the cables at the end of the bow together to the right or left to bring the stops closer together. When the stops feel like one, then the timing is the correct adjustment for your shooting style.
Tiller Adjustment
The tiller holds the placement of the arrow during use. The tiller also helps the arrow align correctly with the shooting mark. The tiller is adjusted by making a mark at the nocking point where the arrow aligns with the string. Increase the tightness of the string to help the bow keep steady during shooting and to keep the arrow flying straight. Loosen the tiller to help make the arrow have more movement.
Arrow Tuning
Tuning the arrow shaft where it attaches to the bow can have a large impact on the quality of the bow shot. Finger-released arrows need a nock point installed about three-eights or one-half inch above the finger rest. If a release agent is used, the nock point is lowered to about one-eighth to one-quarter inch above the rest area. Adjust the position of the nock point until the arrow and string spring out along the same arc.
Shaft Position
The shaft position of the arrow after it hits the target is important. The shaft should hit the target straight on rather than at an angle. The best way to correct this problem is to shoot an arrow at a piece of paper on a target. Inspect the angle that the arrow entered the paper to make adjustments. If the arrow is tail high, lower the nock point. If the arrow is tail low, then move the nock point up. Move the rest to the left for left-pointing tails and right for right-pointing tails.
