How to fix a Bosch 3915 Saw if I cannot move the miter adjustment?
If you cannot move the miter adjustment on your Bosch Saw, the lock knob may be tightened or the detent engaged. Loosen the lock knob and move it out of detent. Sawdust under the table can also cause this issue; vacuum or blow out the dust, wearing eye protection.
Why doesn't my Bosch 3915 motor start?
If your Bosch Saw's motor isn't starting, first ensure the unit is properly plugged into a functioning outlet, and try a different outlet if necessary. Check the power source fuse, and replace with a 15-Amp time delay fuse or circuit breaker if needed. Also, worn brushes can prevent the motor from starting; in that case you should replace them.
What to do if my Bosch 3915 blade binds, jams, burns wood, or makes rough cuts?
If your Bosch Saw blade binds, jams, burns wood, or makes rough cuts, it could be due to improper operation. Also, check if the blade is dull and replace or sharpen it. Ensure you are using the correct 10” diameter blade designed for the material you are cutting. A bent blade can also cause these issues, so replace it if necessary.
Why does my Bosch 3915 vibrate or shake?
If your Bosch Saw is vibrating or shaking, it might be due to a saw blade that is not round or is damaged. In such cases, replace the blade. Also, check if the saw blade is loose and tighten the arbor screw if needed.
How to fix a Bosch Saw when the brake does not stop the blade in about 5 seconds?
If the brake on your Bosch Saw doesn't stop the blade within 5 seconds, the brushes may not be seated properly, might be sticking, or could be worn. Inspect, clean, or replace the brushes. It could also be that the motor overheated from using a dull or too heavy blade, a non-recommended accessory, or rapid on/off cycling; use a sharp blade. A loose blade bolt can also cause this issue; tighten the blade bolt.
What to do if the head assembly of my Bosch 3915 Saw will not fully rise or the blade guard will not fully close?
If the head assembly of your Bosch Saw won't fully rise or the blade guard won't fully close, it could be due to sawdust accumulation. Clean the head assembly to resolve this. Ensure the cover plate is tightened after replacing the blade.
What to do if the head assembly of my Bosch 3915 does not slide freely when attempting a slide cut?
If the head assembly of your Bosch Saw does not slide freely when attempting a slide cut, the slide rail lock knob might be tightened. Loosen the slide rail lock knob. If the head assembly slides forward and back when making a chop cut, the slide rail lock knob might not be tightened. Push the head assembly completely against the stop and tighten the slide rail lock knob.
Why does the head assembly on my Bosch Saw not move from the 33.9° position?
If the head assembly on your Bosch Saw does not move from the 33.9° position, the bevel detent lock pin might be engaged. Pull the lock pin out and rotate it 90°.
What does a flash of light from the motor endcap of my Bosch 3915 Saw when the switch is released mean?
A flash of light from the motor endcap of your Bosch Saw when the switch is released is normal, indicating that the brake is working properly.
