Running Concrete Chain Saws

Running Concrete Chain Saws

Regardless of the Brand (ICS, Husqvarna, Stihl), concrete chain saws can be an effective tool for deep cutting through masonry and concrete walls for the installation of various openings such as egress windows and doorways.

A few points to consider when running concrete chain saws.

• Chain tension is critically important to the longevity of your saw’s power head, as well as the life of your chain. Proper chain tension is checked by pulling the chain around the bar by hand. There should not be any tight spots as it moves past the nose of the bar and the drive sprocket. If you cannot easily pull by hand the chain is too tight and needs to be loosened slightly.

• Periodically, an operator should stop the saw and check and adjust chain tension accordingly. If he chain is too loose it could come off the bar or allow the drive sprocket to spin without turning the chain and potentially chew up drive links. When the chain stretches to a point where the drive links are hanging approximately ½” to ¾” below the bar, it is time to tension the chain.

• Concrete chain saws must be run with water. Dry cutting is not allowed. Water is the lubricant that is cooling the chain, and preventing premature chain stretch.
• Typically, a pressurized pump will not provide enough sustainable water for cutting. A dedicated water source should be used - either from a water truck or a house spigot. The minimum water pressure required is 20 psi. Insufficient water supply may result in excessive wear to the diamond chain.
• Filter life is almost a non-issue with concrete chain saws due to the nature of cutting. 12 times per year, or during your regular maintenance schedule, you should clean or replace the filter element.
• Concrete chain saws use mixed gas and oil. A high-quality, fully synthetic oil and higher octane gas should be used for best performance and longevity of the power head.
• After cutting or at days end, the power head, bar, chain and starter rewind should be sprayed off with pressurized water to rinse out and wash away concrete slurry from the saw. Once rinsed off, spray the saw down with a lightweight lubricant, such as WD40, to prevent rust and prepare the saw to be in good working order for the next use.

Following these few simple points will prolong the life of the power head and give you trouble free operating hours when running your concrete chain saw.
