Milwaukee 6180-20 14" Chop Saw Abrasive Cut-off Machine Questions & Answers
Tripping 20 amp breaker
when things start overheating componants start to break down. sounds like you need to check the armature and field for burnt areas. at least change the brushes. were you bearing down hard? sounds like the motor may not be enough to cut quickly, maybe more slowly. hope this helps

How to replace the blade
UNPLUG tool first, there is a spindle lock near the upper guard/gearcase that needs to be depressed and slowly turn the wheel till it locks, The blade bolt is standard thread. You can go to milwaukeetool.com and with your model number download an owners manual for this tool. Let me know if you need more assistance.

I need to know how
Look around the housing where the switch handle bolts on. You should see a spindle lock pin. With the unit unplugged you want to push in the pin and when you go to tighten or loosen the blade bolt the spindle will lock into place. Sometimes you need to turn the spindle a bit for the lock to catch. Once you have changed the blade just release the pin as it is spring loaded.

Bad arcing were brushs
From
[email protected] Hi dkhallquist. When you cleaned the comuntator did you carfully clean the groves as they may have enough trash to make the brushes ride roughly on the comuntator.

6180-20 chop saw trips 20
If it trips the breaker as soon as you hit the switch, check the power circuit. Check the power cord for frays or cuts, especially where the cord goes into the saw. Remove/split the handle and check the wires into and out of the switch and to the brushes and field. Lood for burned or melted wires or case parts. Milwaukee is notorious for running lots of small wires in very tight places. Make sure none of them got pinched when the tool was assembled. Watch for this also when you reassemble the saw. Check the brushes, if they're worn or broke they can cause a short on the armature. If these all check out you need to have the armature checked on a growler for shorts.
If the saw runs for a few seconds then trips the breaker I'd check for gear and bearing problems. Cehck for free, smooth movement of the bearings on the armature and blade drive assembly. The blade should turn freely by hand. Feel for undue resistance or a gritty feel in the bearings and gears. If necessary replace any offending parts.

My 12" Milwaukee Miter saw is making a noise when braking?
Screeching is always caused by dry metal on metal. It need oil on anything that spins or slides. See if the brake actually has fibre pads like the disc brakes on your vehicle.

I have a Milwaukee 6390 circular saw. It keeps blowing a breaker even without an extension cord?
If your Milwaukee 6390 circular saw is tripping the circuit breaker even without an extension cord, it could be due to a few reasons:
- Overloaded circuit: The circuit may be overloaded with too many other electrical devices or appliances. Try unplugging other devices or turning off lights on the same circuit to see if that resolves the issue.
- Short circuit: A short circuit can occur when the insulation on the electrical wires inside the saw becomes damaged or frayed, causing them to come into contact with each other. This can cause a sudden increase in current flow, which can trip the circuit breaker. Check the saw's power cord for any visible damage or wear, and consider having it professionally inspected if you suspect a short circuit.
- Faulty circuit breaker: It's possible that the circuit breaker itself is faulty or worn out. Try plugging the saw into a different circuit and see if it still trips the breaker. If it does, the issue may be with the saw itself.
- Motor overload: If the saw's motor is under strain or is overloaded, it can trip the circuit breaker. Check the blade for any binding or resistance, and ensure that the blade is sharp and properly aligned.
If none of these solutions resolve the issue, you may want to consider taking the saw to a professional repair shop to have it inspected and repaired.
