Rf1101 makita router lost serious power and is sounding wounded

The brushes seem fine except it seems to me that there is a lot more spark than there should be. about 1/2inch left on the brushes. when the power loss happened there was a slight burned smell but not overly strong like when you burn out a motor. when you turn up the speed it seems to miss or stutter but you can't notice it on low speed. this router has seen a bit of work but not overly abused. i have taken the top off and blown it clean and checked the electrical connections but there was nothing abvious. did not really want to try to take the armature out to check for damage justin case there was something that was a common problem with these routers. please help

You dont have to take the armature out to look at the commutator, just remove the brushes (unplug tool first) and get a flashlight and look into the brush tube and slowly turn the shaft by hand and look for a discoloration or unusual look on the comm bars. The slight burned smell might have come from the speed control or the switch itself, but look at comm and then go from there. You can get a breakdown for this tool at Let me know if you need any more help

Hi David,

I have nearly the exact same issue with a Makita RF1101 router. The brushes still have about 1/2 inch left on them. When I look inside the hole, I can see something shiny metal that when I turn the collet it spins and alternates between a dull dark color and a shiny gold or brass color. How can I fix this?

What hp router is best to make cabinet raised doors

I used to use a Ryobi 2.5 hp and it worked fine but if you are concerned go higher hp. It's probably more important that the router is a variable speed model. The bigger the size of cutter required for raised panel doors the more torque and revs are produced. You need to ensure starting on slowest speed and adjust up to speed required. Speed should be based on size of cutter and to me is set by sound( a nice hum, not screaming) and vibration( NO VIBRATION)! The cut needs to be done in several passes, maintaining constant feed speed,( don't burn your expensive cutter) allowing cutter and machine to do work maintaining the hum and no vibration. And of course set your guards etc!! If this is on going work for you perhaps look into a spindle moulder with attachment to take router cutters

Router making a squeal noise and sparks from the brushes.

Squealing is usually associated with bad bearings. Sparks from the brushes is being caused by the motor pulling harder than usual because of the bad bearing. Sparks come from the carbon being burned off the brushes. I'd replace both, brushes are inexpensive and will make the tool work better and longer.

Won't come on brushes seem fine

The issue I find most with these routers if they are not working is the main power switch. They usually are the culprit. They are easily changed is you want to tackle this job yourself. One other problem I see is the speed control module, just remove the two screws from the top of the tool and inspect the module with the knob. Look, for any burning or melting (this is rare). Just find a Bosch service center in your area, they will have the parts you require.

Vince, it sounds like you will have to replace your variable speed module. It is item number (5) in the breakdown and runs about 80.00.
The part number is 631397-2.
Click on the Parts Beakdown Icon on the left hand side of the page. I hope this helps, let me know if there is anything else you need.

I haven't used my porter cable router for several months. Went to use it today and it won't run...any suggestions?

If it was stored in an area that wasn't dry it could be as simple as replacing the motor brushes. Part number 869659 or 824216 is available for about $5.00. The motor is pretty easy to take apart if you want to give it a good cleaning. Check your brushes first a coin or a screwdriver to take out the black plugs on the sides adjacent to the power cord. they are spring loaded so be careful. I've lost one in my personal bermuda triangle garage floor. if they look corroded take a piece of fine grit sand paper and lightly sand them. see if that does the trick, if it doesn't and you are inclined i would clean the inner and outer fields of the motor.

My freud ft 3000 will not run.i have power to the switch

First thing to check is that your brushes are touching. Remove the 4 screws holding the top cover on. You will see the two brush holders and brushes. Use a multimeter of the ohm setting to check the continuity through the brushes. Do not press on the brushes hard, just make contact with both brushes and the probes. If you get continuity it is not the brushes, it there is no continuity then inspect further to see if the brushes are worn. At this point if it is not the brushes the variable speed switch is more than likely the culprit. If you are getting power to the on/off switch and through the on/offswitch, check to see if you are getting power through the variable speed switch. To do this do not plug the cord in. Use the ohm meter to check continuity of the black wire to the wire coming out of the variable switch with the variable switch at the highest setting. As you turn the dial down the resistance will increase but should not be disrupted. If there is not continuity at all it is the variable speed switch. You can confirm this by bypassing all switches and connecting the power directly to the motor with alligator clips. Make sure you have the router in a vice when you do this though. It has a lot of torque and will jump off the bench if not secured. If you do not feel comfortable doing this please do not attempt it because you could seriously injure yourself or someone else. Any questions please post back and I will check back on this inquiry.

I would first use compressed air and thoroughly blow thru the vents. Second I would take out the brushes they have a black cap over them and after removing wipe them off with a clean rag and reinstall. Look at the cord for cracks in outer jacket. Plug in and try again. If this doesn't work UNPLUG tool and turn collet nut by hand and connect again and retry. That is about the only things you can do safely. When storing sometimes dust and debris gets inside tool and can make the brushes loose contact with the armature
