Carbon Express Piledriver 390

Sometimes due to improper handling, your crossbow might run into some problems. But don’t worry, because it’s not something that you can’t fix. 

Here we've detailed 5 possible problems you might run into with your piledriver 390.

Problem 1 of 5: Crossbow Failing To Cock

Sometimes the cocking mechanism might slip and it won’t fire. It happens when the string isn’t pulled all the way back. This inadequate force in the string can cause it to not cock properly. 

Also, you might run into some issues when the safety mechanism is on. 


To fix this, make sure the string is pulled properly. For that, you can invest in a good arrow puller. Using the hook, pull the string until you hear the cock. After that, you’ll have no problem firing it.  

But in case you’re doing it by hand, it’s a little hard work. You have to do the same thing here as well. Pull the strings uniformly with your finger until you hear the cock. 

Sometimes the problem can be with the strings. In that case, you have to replace it with a new one. 

Make sure that the safety is off while firing. Check and grease the cocking mechanism for easy movement.

Problem 2 of 5: The Sight Isn't Accurate

In some cases, your sights may not be totally accurate from the box. It might be because of bent iron sights or a hasty setup. Moreover, the condition you’re hunting around also matters.  

Inaccurate sights decrease your accuracy and lead to a waste of arrows. In turn, it makes your hunting adventure a frustrating ordeal.


To fix the iron sight you have to recalibrate it according to the user manual. But if the sight is bent or faulty, replacing it is the only solution. You can calibrate the new one according to the manual and start using it.

However, to solve it permanently you can buy a good archery sight that’s 3D. This will reduce your downtime while hunting and it's easier to operate. Moreover, it also gives you the best experience with proper sight.

Problem 3 of 5: Fails To Fire While Cocked And Loaded

This problem usually happens because the bolt isn’t seated properly. Hence, it slides forward or gets stuck. It leads to the failure to fire. 

Moreover, at times the bolt can be faulty and this causes the issue. 


To fix this, make sure if the bolt is seated properly. If misaligned, you have to recalibrate the alignment. For that, you need to tighten or loosen the screw holding the receiver.

Now, if the receiver rattles a lot, you’ll have to tighten the screw. However, you’ll have to loosen it if it’s too tight. Then, adjust it so that it’s on the same length as your bolt. 

Check the bolt receiver has any defects or damage. In that case, you’ll have to replace it with a new one.
