Please be sure to watch the instructional videos first. If you still have problems, the following troubleshooting tips may help.
2. Snaps Stopped Closing After Wash/Dry
3. Snaps Falling Off Fabric
4. Snaps are Cracking
5. Snaps are Uneven
If you are using basic pliers, a slightly uneven press is normal but should not affect the functionality of the snap. Tightening all 3 metal screws may help. These screws should be checked and tightened periodically. If your flattened prongs are severely uneven, try "resetting" the pliers by taking apart the bottom black cap die tray and the top metal shank and then putting the pieces back together.
6. Pliers are Crushing Snaps
This happens when the inappropriate black cap die tray or top metal shank are used. Refer to the video instructions to ensure you have the correct parts in your pliers for the particular snap you are using. Note that instructions may differ depending on the pliers model and snap size.
8. Tool No Longer Applies Enough Pressure
If you've been using your pliers or table press for a while with good results, then one day they just don't seem to work as well or your newly installed snaps won't close, it may be time to replace some of the parts. Just like any mechanical tool, parts may wear out over time.
Basic Pliers: The tension spring, rubber head, and cap die will wear down the most with continued use. If any of the metal screws are significantly loose, those should be replaced as well. Parts are available for K1 or K2 pliers.
Table Press: Any rubber or springs on the dies will lose their elasticity with continued use, so dies will need to be replaced periodically. Dies are available here.
9. Fabric is Tearing
Fabric will tear if it is delicate, thin, or stretchy, like knits. To prevent ripping, reinforce your fabric with a sturdier material at the point of the snaps.
If you are using size 20 plastic snaps on such material, try size 16 plastic snaps instead, which have a slightly gentler grip. Reinforcement may still be necessary.
