When it comes to power cutting tools, a few tips will help get the most out of your investment.
Chain Tensioning
A diamond chain that is too tight may rob power, reducing cutting performance and increasing chain friction, which can result in chain stretch. A diamond chain that is too loose could be thrown off the bar or allow the sprocket to turn without turning the chain, which will damage the drive links.
A chain should originally be tensioned so that the drive links on the bottom of the guidebar just touch the guidebar groove. When a chain stretches to a point where the drive links are hanging approximately 1/2” to 3/4” below the guidebar groove, it is time to tension the chain.
Proper use of power cutters can increase the life of your product.
Water Pressure
Insufficient water supply may cause chain breakage, as well as damage to the guidebar, nose and drive sprockets. Heat generated by running a chain “dry” can disintegrate O-rings and degrade the diamonds. Proper water pressure (a minimum of 20 psi with a flow rate of 2 gpm) reduces wear on the chain chassis and bar rail/nose sprockets.
Drive Sprocket
There’s a point in the life of the drive sprocket where it no longer functions but rather causes damage to the chain and potentially the guidebar. It’s important to check the drive sprocket for wear before each use and every time a new chain is installed. If it’s noticeably worn down — to the point that the teeth become pointed or a groove cuts through the top of the tooth — it should be replaced. Generally, every 2-3 chains. WW
