If you want to keep your crossbow in top condition, proper maintenance is essential. Crossbow maintenance doesn't require a ton of time or effort but attention to a few details can make all the difference.
North American Whitetail's Mike Clerkin shares some tips in this video to help you do the job right along with some bonus tips on ensuring you get the most accuracy from your crossbow.
For proper crossbow maintenance, start with using a good lubricant on the string, being careful to avoid the serving. Also lube the rail ever 100-200 shots to keep any restriction on the arrow at bay.
Also be sure to check all screws and bolts to make sure they're tight.
Proper crossbow maintenance will not only keep your crossbow in good functioning condition longer, it will also help increase accuracy.
