At the sliding table saw , a particularly high number of accidents occur in the woodshop. It is one of the most dangerous machines in the workshop—and things get especially critical when working with narrow workpieces. If the width is less than 120 millimeters, your hand will inevitably come close to the blade. That’s exactly where it gets dangerous.
The RUWI Safety System Premium takes a different approach: You clamp the workpiece tool-free onto the sliding carriage and guide it past the blade. Your hand stays out of the danger zone—even when cutting small, narrow, or angled pieces. Tested by the German Social Accident Insurance Association for the Wood and Metal Industries (BGHM) and awarded the DGUV seal of approval.
What sets it apart from the Classic model is the ability to trim long workpieces. You clamp the plank simultaneously at the front and back using two swivel clamps. This prevents it from tilting and ensures it doesn’t shift during the first cut. The holding tips on the narrow auxiliary stops grip the wood at specific points, ensuring nothing slips under feed pressure.
Here's how to use it
-
Cutting small and narrow pieces: Clamp the workpiece onto the sliding carriage and guide it past the blade—keeping your hand out of the danger zone.
-
Trimming long, warped planks: two swivel clamps hold the front and back at the same time—this way, you can trim a warped oak plank on your own, without a second person or any auxiliary supports.
-
Bevel, miter, and wedge cuts: using the adjustable auxiliary stop, even on tapered workpieces—the rubber edges of the Multiplex stops prevent slipping.
-
Small production runs with varying shapes: tool-free changeovers—everything is set up in about 10 seconds, instead of tightening screws.
-
Everything is organized next to the saw: all components are hung within easy reach on the wall panel (620 × 420 mm, powder-coated sheet steel)—nothing gets in the way, and you never have to search for anything.
Does this fit your sliding table saw?
When ordering, select the model by manufacturer—the swivel arm is designed to fit the respective sliding carriage: Altendorf (100 mm), Format 4 (130 mm), Martin (170 mm), Felder X-Roll (130 mm), and Hammer Series 3 (75 mm). For all other machines, select the “Other Manufacturers” option—the swivel arm will be customized after an individual assessment of your saw.
Many carpenters safely cut small pieces using “Fritz und Franz,” the sawing aid from the employers’ liability insurance association. It’s tried-and-true and affordable. The RUWI system takes it two steps further: tool-free clamping in seconds instead of screws—and the ability to trim long planks, something “Fritz und Franz” can’t do.
The Premium is the ideal choice for workshops that handle a wide variety of workpieces, as well as for schools and training facilities with high safety standards. If you primarily cut small, narrow parts, the Classic model is often sufficient—it can be upgraded later with a second swivel clamp to the Premium model.
