Zippers in chainsaw pants get a hard time. We’ve tested and trialed every available zip that we could find to get the best performance. Our current zips are rugged with a reverse coil or chain to keep debris out. Dirt, wood chips and other material can still get into coil between the teeth. The slider then starts sticking and the natural reaction is to pull the slider. This can damage the chain but most often it separates the front and back of the slider. The result is that the slider pulls up but the chain or the parts on each side of a zipper fail to mesh.
This video shows you how to use multi grip pliers to gently squeeze the top and bottom of the slider back together so the zip starts functioning again.
Some additional tips for zip care and maintenance
1. Always wash the pants with the zips closed. This helps keep the sawdust fragments out of the zip teeth and makes sure that the slider does not come under pressure during the washing cycle.
2. Stop pulling if the zip is hard to pull and see what is jamming it. Removing the obstruction is the best way to get the zip moving again.
3. You can keep your slider moving freely by running a pencil up and down the teeth of the zip a couple of times. This will help reduce wear on the teeth and slider.
