What to do if my Performax 240-3669 Saw blade binds, jams, burns wood, saw vibrates or shakes, or laser line projection is hard to see?

  If your Performax Saw blade binds, jams, or burns wood, and the saw vibrates or shakes, or the laser line projection is hard to see, several factors could be at play. It might be due to improper operation (refer to the OPERATION section), a dull, warped, or damaged blade, or an improper blade. Ensure the arbor bolt is tightened. If the light in the work area is too bright, move the saw to an area with proper lighting. If there's sawdust on the laser lens, clean it with a soft, dry brush.

Why doesn't the brake stop the blade within 10 seconds on my Performax 240-3669 Saw?

  If the brake on your Performax Saw doesn't stop the blade within 10 seconds, there are a few potential causes. The motor brushes might not be sealed or are lightly sticking, so inspect, clean, or replace them, referring to the MAINTENANCE section. The motor brake could be overheated due to using a defective or wrong size blade, or rapid ON/OFF cycling, so use a recommended blade. Lastly, the arbor bolt might be loose, so retighten it.

  If the angle of cut is inaccurate on your Performax Saw, make sure the miter table is locked using the miter locking knob to tighten it. Also, too much sawdust under the table can cause this issue, so vacuum or blow out the dust, wearing eye protection.

  If the cutting arm cannot fully raise or the blade guard cannot fully close on your Performax Saw, it could be due to parts failure, so contact an authorized service center. It might also be that the pivot spring was not replaced properly after service, so contact an authorized service center. Sawdust buildup can also cause this, so clean and lubricate the moving parts.
