To Next PageTo Next PageWhy does the head assembly slide on my Bosch Saw when making a chop cut?
If the head assembly of your Bosch Saw slides forward and back when making a chop cut, it is likely that the mechanism lock lever is disengaged. Pull up on the mechanism lock lever tab to engage it.
Why Bosch GCM18V-12GDC head assembly will not fully raise?
If the head assembly of your Bosch Saw will not fully raise or the blade guard will not fully close, first check if the head assembly lock pin is engaged. If it is, pull out the lock pin to allow the head assembly to go up. Sawdust accumulation can also cause this issue, so clean the head assembly.
What to do if head assembly does not slide freely on my Bosch GCM18V-12GDC Saw?
If the head assembly on your Bosch Saw does not slide freely when attempting a slide cut, it's possible that the mechanism lock lever is engaged. Push down on the mechanism lock lever to disengage it.
Why I cannot rotate the table to change miter angle on my Bosch Saw?
If you cannot rotate the table to change the miter angle on your Bosch Saw, first check if the miter lock knob is tightened; if so, turn it counterclockwise to loosen it. Also, ensure the miter detent lever is not engaged with a detent (slot) in the detent plate; pull up on the lever to disengage it. Sawdust accumulation can also be a factor; vacuum or blow out dust around the turntable, wearing eye protection.
What to do if Bosch GCM18V-12GDC Saw blade does not cut completely through workpiece?
If the blade of your Bosch Saw does not cut completely through the workpiece, first check if the depth stop plate is pulled out for non-through cuts. If so, push it inward to set it for full-depth cuts. Also, ensure that the replacement blade is a full 12" (305mm) in diameter.
How to fix Bosch Saw bevel angle that is not securely held?
If the bevel angle on your Bosch Saw is not securely held when the bevel lock lever is pushed, the bevel lock lever likely needs a tension adjustment. Increase the bevel lock lever force by adjusting the tension nut.
Why does my Bosch GCM18V-12GDC vibrate or shake?
If your Bosch Saw vibrates or shakes, it may be due to a saw blade that is not round or is damaged. Try replacing the blade. Also, make sure the blade is properly seated on the inner washer. If the issue persists, it may require authorized service.
What to do if Bosch GCM18V-12GDC blade binds, jams, burns wood, or makes rough cuts?
If the blade of your Bosch Saw binds, jams, burns wood, or causes rough cuts, it could be due to several reasons. First, ensure you are operating the saw correctly. Refer to the Saw Operations section for guidance. The blade may also be dull, requiring replacement or sharpening. Using the wrong type of blade or a bent blade can also cause these issues. Replace the blade with the correct 12" (305mm) diameter blade designed for the material you are cutting.
