Anyone having problems pushing down the head of their Kapex?
My saw has always been stiff, just getting worse.
Hi there Sully! Sorry to hear that your Kapex is getting stiff. It has been my experience that this is pretty common for Kapex saws after they have been in use for a few years (I've seen this on my saw and at least two others). On the back side of the motor, on the bearing that Shane has referenced, there is a shiny metal arm that rides on top of the bearing. It has been my experience that, over time, this arm deforms where it rides on the bearing. Over time, the arm "mushrooms" out and develops a bit of a divot. This divot prevents the arm from sliding smoothly on the bearing, thus preventing the blade guard from retracting, thus preventing the head assembly from smoothly plunging down into the work.
How to fix it? Well, you can go two ways. I attempted the repair myself a year ago. I ordered the parts, and spent well over two hours attempting the repair. Ultimately, I almost lost a small spring, spent a lot of time mucking around, and eventually got the part replaced. After all of that, the saw still didn't operate properly. Eventually I shipped the saw to Festool Service. I wish I had done this in the first place. I think I spent ~$275 for the service, including shipping. Festool replaced the fences, armature, a whole slew of other parts, recalibrate the lasers, fixed the stiff operation, and had the saw back to me within ~8 days of when I originally shipped it.
If the shiny arm is indeed deformed, while you might be able to fix it yourself, I strongly recommend sending the saw in for service. These tools, while tough, DO require maintenance, and you'll probably be money ahead having Festool fix it, versus downtime and lost revenue by you trying to do it yourself.
I covered this in another thread roughly a year ago, in which I think I included the part #'s you'd want if you were to try it yourself.
Best of luck, I hope your saw is back up and running smoothly soon! [smile]
