I spray coat the guide rail and the bottom of the saw with a dry lubricant such as Topcote.
Silicone and wax will also work well. Is this a necessary step? Not at all. The saw and guide
rail work excellently without any lube. I just find they work even better with it. There’s your
first $10 tip. The next step is to trim the splinterguard on the new guide rail. It’s hard to get
this wrong no matter how you do it (as long as the guide jaws are set properly). But I’ll
show you the way I think gives the best results.
First set the speed on your saw to 1. You want to run the saw nice and slow for trimming.
Next, set the depth on the saw to about 6mm or 7mm and set the guide rail on top of a
piece of scrap plywood. I find that if I trim the splinter guard without a backerbaord, with
the edge hanging in space, I don’t get as clean an edge.
