How to Troubleshoot a Compound Bow

Compound bows use multiple moving parts to control and operate a system of cables and pulleys. A properly-tuned bow should fire in a consistent pattern, however, performance issues do happen. Monitoring all parts and performance of a bow makes it easy to pinpoint issues. Troubleshooting an unfamiliar bow requires inspection of all parts to ensure the bow is safe and functional. Troubleshooting isn't difficult, but requires attention to detail.

      Check all of the accessories for loose hex bolts. The sights, arrow rest, stabilizer and string stopper must be stable for consistent performance. Loose hex bolts cause the items to shift and accuracy is affected. Test each bolt with a hex wrench to ensure the items remain stable.

      Inspect the string for loose serving thread. Loose thread will begin to unravel and the peep sight and nock loop will shift position. Remove and replace loose and worn serving thread with fresh material and tight wraps.

      Inspect the bowstring and cables for damage and dry areas. Cover worn sections of the bowstring with serving thread to add protection. Add bowstring wax to dry sections of the string. Replace the entire bowstring if the material is stiff and damaged with nicks and heavy wear.

      Draw the bowstring and feel for uneven resistance. Listen for squeaking as you draw. Slowly return the string to the resting position. Locate the axles on each end of the bow. Add a drop of silicon grease to the eccentric on the axle. The eccentric is the point where the axle pivots.

      Inspect the limbs for fractures and uneven curves. Damaged limbs render the bow useless and the entire bow must be replaced. Save the string and accessories, they can be reused.
