Measuring a chainsaw bar length is a simple process that can be accomplished in minutes with just a measuring tape. The chainsaw bar length identifies the size of the cutting area of the chainsaw.Continue Reading
The bar length includes the cutting part of the chainsaw, so you typically measure only to the point where the chain is present.
The end of the bar is the furthest point of the bar from the housing.
After you find the point where the chain enters the housing and the end of the bar, simply measure the distance between the two points with a measuring tape.
Turn on the chain brake and clamp the bar in a bench vice. Using a round file and a file guide, file each cutter using two to three steady strokes. Expose new metal, leaving the cutter faces shiny. When a metal burr exists on the edge of the cutter, sharpening is complete. Repeat this process for each cutter, disengaging the chain brake, advancing the chain, and re-engaging the brake as necessary.Full Answer >
To sharpen a chainsaw, switch on the chain brake, place the bar in a vice, and secure a guide between the rivets. Make sure that the arrows on it are facing the nose of the bar. When sharpening the saw, do it at the angle of the top plate of the cutter. Do several strokes using the file on each cutter, which should become shiny when sharp.Full Answer >
If a chainsaw is inoperable, the most likely culprits are the machine's bar or chain. Uneven cutting may be caused by cutters that are filed at different angles, cutters with blunt edges, or uneven pressure caused by mismatched chain sides. Misshapen bar rails are another common area of concern.Full Answer >
Automatic chainsaw oilers utilize a pump and plunger assembly to push the oil into the groove around the bar. As the chain moves around the bar, it forces the oil around the rest of it.Full Answer >
