As with any bow, the strings of a Barnett crossbow will eventually fray, wear out and need to be replaced. Crossbow strings can last from a minimum of 100 shots to several hundred, according to BarnettCrossbow.com. If you're a hunter who subjects your bow to extreme temperatures and moisture, care for your strings to ensure longevity. By waxing your Barnett crossbow every after eight to 10 firings, you can decrease the wear and tear on your strings and extend their use.
Remove the bolt from your Barnett crossbow, and place the bowstring in the uncocked position. Removing the bolt will allow you to wax the strings properly and will prevent accidental discharge.
Remove with a slightly damp cloth any grime from the entire bow, including the strings. You may need to use a putty knife to dislodge large chunks of dirt or caked-on material.
Dry your bow thoroughly with a dry towel, removing all moisture from the bow, including the strings. Also let it air-dry for several hours.
Inspect the strings. If you notice "wooling"--gray fibers threading out from the bowstring--you should wax the bow and strings. However, if you see fraying that goes beyond wooling, you might need to replace the string.
Scoop up some wax using your finger. With your thumb and index finger, massage the wax into the string. Start at one nockend of the crossbow, and work your way evenly and thoroughly to the other nockend.
Apply wax in the same way to any part of the crossbow that the string touches during firing, including any Teflon tape. To reduce friction and improve arrow speed when firing, also apply the wax to the groove that holds the bolt.
- Don't try to speed up the drying process by using a hair dryer or space heater. This will defeat the purpose of using wax on your strings and crossbow to protect it from damaging temperatures and harsh conditions.
- Keep a record of how many times you fire your bow. This will help you keep track of how often you need to wax the strings and how often you might need to replace them.
