Milwaukee PSA-3 Replacement Guide Rail Splinter Strip for GR 800 / GR 1400 / GR 2700, 2780 mm, 4932479070

Milwaukee PSA-3 Replacement Guide Rail Splinter Strip for GR 800, GR 1400 and GR 2700

PSA-3 is not a machine and not part of the saw. It is a consumable for the guide rail - a wearing strip 2780 mm long, replaced once it is chewed up. The pack holds one piece. Milwaukee lists it for the GR 800, GR 1400 and GR 2700.

Where the strip sits

It goes along the cutting edge of the rail, on the top face - the side the blade runs past. That separates it from PSA-5 (article 4932479072), the non-slip strip, which runs along the underside against the workpiece. Milwaukee shows the two with almost the same photograph, so go by the number: 4932479070 is PSA-3.

Why the top face of the cut comes out clean

On the first cut with a given machine and blade, the blade trims the surplus off the strip and its edge ends up exactly on the cut line. From then on the strip holds the wood fibres down against the kerf, so the top surface does not tear out.

When to replace it

The strip is a wearing part. Replace it once the edge is cut away, ragged or lifting, and when moving to a blade with a different kerf or after bevel work - the old edge no longer matches the cut line.

What to check when fitting

Before sticking it down, clear the rail channel of old residue and dust; the surface must be dry and free of grease. Lay the strip without stretching it and without trapped air. One trial cut into scrap then shapes the edge to the machine and blade.

Which rails and which machines

At 2780 mm the strip covers the longest rail, the GR 2700, in one piece; the GR 800 and GR 1400 are cut to length. The M18 FPS55, M18 FCSG66, M18 FMCS66 and CS85 CBE relate to this strip only through the rail - Milwaukee lists them as compatible with the GR 1400, not with the strip.
