The new Festool CSC SYS 50 cordless table saw has been out for a couple of months now, and we’ve heard about some problems with it.
The most common complaint so far has been about alignment issues, which one wouldn’t expect to see on a Festool product, let alone what’s supposed to be a high-precision saw
Early adopters have been complaining that the table saw’s table, sliding table, and extension table are not aligned or coplaner out of the box, requiring users to fix and adjust the tools themselves.
Some users have taken to fixing the sliding table alignment with playing cards or other types of shims.
One user shimmed their saw and then reported the table saw’s blade angle didn’t match the settings at 45°.
A ToolGuyd reader reported a different kind of problem. Mike shared that, after shimming his Festool cordless table saw’s sliding table to compensate for its out-of-the-box tilt issue, he discovered that the very center of the table isn’t flat.
So, in addition to being tilted out of the box, the sliding table is cupped.
Mike says that Festool customer service responded, and said that they said the extruded table is intentionally cupped.
Looking online to see if anyone else has reported this, I found one other user saying that their table is slightly deformed upwards around the blade opening.
We reached out to Festool USA and asked them to comment about the issues, if they will be fixed on future production batches, and if all users should expect to have to shim the table. We also requested a loaner to check out the problems firsthand.
We gave them a full business day to respond and were told they are working on a statement.
Update: Festool USA’s Response
Thanks for sharing your concerns regarding the new CSC SYS 50. It is common when a new product comes to market with a new design and use of technology that some may be skeptical and extra critical of the product and its components. In the case of the CSC SYS 50 we have not had any reported defects concerning the high-pressure cast top. It is purely cast and not machined like a cast iron saw might be; however, we hold a tight tolerance for these tops and if there is truly any defect with the top, it most likely will not be corrected with shims and would have to be replaced. The head of our service department says that they have only replaced one top since the machine was introduced. That top was for a machine that the customer dropped and it caused one corner to be chipped. If the concern is regarding the sliding table mechanism, again shims should not be needed. The sliding table itself is extruded aluminum (using the same processes we use with our guide rails) and also have a tight tolerance for flatness. Some consumers expect that this sliding table should be coplanar with the cast top that is mentioned above. This is not how sliding tables should be set up. The sliding table surface should be slightly proud of the cast portion of the top. This can be adjusted by the consumer if they desire by quite a significant range above and below the cast surface. In case of concern, we suggest customers to contact us directly. Our phone number is right on the tool and we have application and technical staff prepared to support any inquiries.
I have seen some complaints about coplanarity, but the bulk of the complaints seem to be about the sliding table not being flat or in parallel alignment with the cast top, with shims needed to compensate for the tilt.
The misalignment seems to vary, with users reporting a deviation of up to 1°.
After spending about two hours fiddling with this and settling on the solution [playing cards as tilt shims], I did call Festool.
When I explained the problem to the “applications” customer service agent, his response was that “the sliding table should be higher than the saw body in order to allow for the clearance necessary for the cut.”
I explained several times that what I was describing was that the table itself was not level from right to left but after several minutes, it became apparent that my best course of action is to send the saw in.
I found a video showing what looks to be the problem some early adopters are complaining about:
So here’s the question – isn’t the sliding table supposed to be flat and parallel to the main table saw surface?
We asked Festool USA rep How much cup and tilt deviation are acceptable or within tolerances? but have not heard back.
