Reassemble power and wiring questions

[John Scholz]

Hello, I'm a newbie and recently bought a used BT3000. I ended up having to disassemble it to replace the belts and shims to get it to raise and lower the blade. While doing so, I took apart the power assembly to get better access to the motor and, stupidly, didn't take pictures. So now I am attempting to reassemble the power related parts to be able to turn the saw on and off with the on and off buttons, etc. FYI, I can turn the motor on and off directly by plugging the machine into a wall outlet. I have some pictures of parts that I have attached that I cannot figure out how they connect.

Any info, pictures, etc. that people here can provide is much appreciated and thank you in advance.

My only comment is that the switch pictured is the old switch they used for the first year production about 1992-1993.
Never had one or had one apart.
There was a recall on the switch, sadly they are no longer able to send replacement switches. Lots about the switch in the old threads if you search for it. Or read the my BT3_FAQ document.

Where's the rest of it? The switch looks to be a momentary switch with the plastic parts operating and canceling the switch. I will look to see if I still have that switch, but as Loring points out, those were recalled. I received one of the last free replacements, and I'm thinking a lot about replacing that with one more accessible. As it is now, I have to reach under the overhang and fumble the switch blind, as you would have to do if that switch were operational. I'm thinking to replace the original with a plug-n-play switch like these:

and mount it in a better position

Here's my comment:
As I mentioned it looks like you have the original switch from the front, altho its hard to tell from your front panel photo which is dark. The original switch had two buttons one red (off) and one green (on) when you pushed on the other popped out.


Speculation:

From your pics It appears to me that the switch comes into two parts, a front assy with the two buttons stuck to your saws front panel and a "microswitch" assembly that snaps on the back (or else you broke it) The red button on the back part is the plunger, pushed by the actuator button to turn on the switch. This is totally guessing but the back part looks like it might snap into the front part and be retained. Probably only two possible orientations. All the wires are already connected to the back part of the switch.

Maybe there's a back cover for the assembly that holds the microswitch in place and protects against shorts? I see four mounting holes threaded in the corners of the front piece

Wouldn't it be possible, and a better idea to simply swap this switch out for one of the newer style safety switches anyway?

Direct Ryobi replacement No longer available.

I agree with DB, just replace it with something like this and move on. It’s much easier to locate to stop the saw, and will likely last 100 times longer than the junk it came with.

Sorry LCHIEN not the switch I was talking about. capncarl got it though... I guess I wasn't clear enough... My saw came with a spare switch, which is getting funky now and I will likely go with one of these heavier duty paddle swtiches as a replacement.

[LCHIEN]

so how's it going?
Back together?

I have a spare machine just like that. Where do you get parts for it?

[John Scholz]

Thank you all. I'm just now reviewing your replies. As suggested. I'll pass on trying to get what I have to work and get a replacement switch and work on installing it. Everything takes me extra time. I'll let you know how it goes. I was working on joining 2 4x4s end to end with a lap joint for part of shed foundation using my circular saw. It would have been 2 cuts with a 3 3/4 table saw blade on my BT3k but with my circular it was a battle and required chiseling and still requires more chiseling to even out the laps. I'm also not using the best of wood so I'm paying the price in terms of accurate measurability and time and effort but that's the tradeoff. Thanks again.

Shipping to the Philippines likely will be problematic for our members.
