replacing switch on Makita JR3000V reciprocating saw

[775684]

I am replacing the switch in my Makita JR3000V reciprocating saw. The switch part # is 650206-6. I failed to mark the wires from my old switch and am trying to figure out where the wires go. There are 2 blue wires coming from the motor, and a black and a white wire coming from the cord. The switch has 4 holes for attaching the wires. Two of them arer marked M1 and M2. The other 2 are marked C1 and C2. I assume that the M stands for motor wires and the C stands for cord wires. Can anyone tell me if that is correct or not?? If that is correct, does it matter which of the 2 blue motor wires goes into M1 or M2? Also, would it matter which of the black or the white cord wires goes into C1 or C2?
One other thing, the 2 holes in the switch marked C1 and C2 have a set screw in them to tighten the wires, but M1 and M2 do not have set srews. How do you tighten these 2 wires?
Could someone help me with this?
Thanks

Hello,

Here is a link to the Makita JR3000V Wiring Diagram. As for the connections without screws to hold the wires in the switch, here is an article and video on How to Wire a Trap Door Switch.

Hope this helps,
