This is the best information I could find. Hopefully this will help you out. http://www.ereplacementparts.com/makita-2704x1-table-saw-parts-c-97_98_216_7512.html Good luck, Marty

You may have a motor winding lead that has touched the case of the motor, shorting out the windings, drawing too much amperage, thus blowing fuses. You may have to disassemble your motor and check the stator windings for a short as well as the armature windings. Also the motor could be hanging up due to bearing trouble and causing the motor to draw too much amperage. Probably the cheapest thing to do would be to replace the motor.

before you replace it, you can try and clean the commutator. To do this first unplug the tool and turn the saw on its backside. remove the brushes and find a emory board (cardboard) while turning the blade by hand (use a glove) lightly touch the board to the commutator to try and clean the surface, While doing this try and notice any raised sections of the comm, if there are any then you would need a new armature and possibly field. I would try cleaning first though. Let me know if you have any more questions.

there are no capacitators that I see. What I would do is unplug the tool and remove the brushes and check there condition for burning/wear and if you can look into the brush tube and carefully turn the motor by hand and look at the commutator for discoloration.

sounds like a faulty switch. before removing write yourself or take a photo of where the wires go. Also check the condition of the brushes, if they are too short the brake won't work either.

Look at eReplacementParts.com and the parts diagrams.

if the motor RPM drops dramatically when the noise starts, it is probably a dry motor bushing, if this just started, lubricating the motor may just fix it.

Just join the two wires together if they work by providing current, or disconnect if they work by being open circuit. Microswitches are normally safety related so bypassing them is not recommended. Just replace the switch if it is faulty. £13.99 https://www.google.com/search?q=microswitches+on+makita+LB1200F+bandsaw ..

First thing I would check are the Carbon Brushes. The are # 75 in the picture

spray with lubricant

You are increasing the load on the bearings.

may be to late for lube noise either bearing or gear worn /debris or damaged

Hello Derek, it seems that your motor or motor brushes have failed please contact the manufacture about replacing the motor brushes.

All portable power tools including saws and most tradesman type saw benches use the light and powerful series wound brush-type motor that doesn't use a start capacitor. The single phase induction motor that does use a start capacitor is far too bulky and heavy for portable tools but is found in many of the static workshop tools. The powerful brush type motor is electrically very noisy and is almost permanently at the edge of self destructing. Good suppression to prevent radio and tv interference is necessary and this also helps protect the motor but a mains transient or power surge while in use can cause an internal surge destroying the insulation of the windings rendering the motor useless in a millisecond. This could be what happened to your saw though it could equally be an internal short circuit in the power cord or inside the saw and these things must be checked before either writing off the tool or sending it for repair.
