    Why is the angle of cut inaccurate on my Performax 240-3687?
    • A
      Angela GordonAug 11, 2025
      An inaccurate cutting angle on your Performax Saw can be due to a couple of reasons. The miter table might be unlocked, so use the miter table locking lever. Also, too much sawdust under the table can cause this issue; vacuum or blow out the dust, and remember to wear eye protection.

    What to do if the brake on my Performax 240-3687 Saw does not stop the blade within 6 seconds?
    • C
      Christopher BryantAug 16, 2025
      If the brake on your Performax Saw fails to stop the blade within 6 seconds, it could be due to a few reasons. The electric hand brake might have failed, in which case you should have the saw repaired by a qualified service technician. Alternatively, the motor brake may have overheated due to the use of a defective or wrong-sized blade, or from rapid ON/OFF cycling, so use a recommended blade. Lastly, the blade screw could be loose, so retighten it.

    What to do if the cutting arm cannot fully raise, or blade guard cannot fully close on my Performax 240-3687 Saw?
    • K
      Kevin MorganAug 20, 2025
      If the cutting arm of your Performax Saw cannot fully raise, or the blade guard cannot fully close, it could be due to several reasons. Sawdust build up can obstruct movement, so clean and lubricate moving parts. The saw-head locking pin might not be set properly, so check, adjust, and properly set the saw-head locking pin.

    Why is the laser line projection hard to see on my Performax 240-3687?
    • J
      John FreemanAug 25, 2025
      If the laser line projection on your Performax Saw is hard to see, it could be because the light in the work area is too bright, so move the Miter Saw to a work area with proper light. Alternatively, there might be sawdust on the laser lens, so clean the laser lens using a soft, dry brush.
