Saw Chain Troubleshooting
8. Backslope on the side plate. Cause: File held too high or the file is too large. Grinders: Saw chain ground at the wrong top- plate cutting angle, grinding wheel is too large, or the grinding wheel is not grinding deep enough into the body of cutter. Symptoms: Slow cutting. Premature wear to saw chain and guide bar rails. Remedy: Resharpen cutters using the correct file guide in the right size held in the correct position. 9. Low depth gauges. Cause: Too much depth gauge removed; depth gauge damaged in use. Symptoms: Rough cutting. Saw chain grabs. Excessive wear to the heel of cutters, opposing tie-straps, guide bar rails. Top-plate breakage and/or saw chain stretch. Remedy: In most cases, cutters cannot be filed back enough to correct for depth gauges that are too low. Replace the saw chain. 10. High depth gauges. Cause: Depth gauge never lowered. Symptoms: Slow cutting. Excessive wear to the saw chain and guide bar rails. Remedy: File depth gauges down to their correct height.
NOTE: Refer to "How to Sharpen Cutters" on page 23 when performing the remedies above.
