Hello to all
Off the bat, I love Festool tools, however my least favorite Festool purchase has been my capex PS 420 EBQ. Ive always found that it suffered from more vibration than my old machine and that the blade bounces around when not under load, making it difficult to align with a mark. I appreciate there is the slow start function, but even at slower speeds the blade does not remain set back between the jaws and is free to move around. Ive always suspected that something was not quite right about the machine, but have lived with it, that is until now.
On the job site the saw started to find it very difficult to cut atall, with a lot of vibration and intermittent rocker action. it was unusable.
I have found im capable of repairing most things so decided rightly or wrongly, to try and repair my tool myself.
On opening the gear box I quickly found a striped small pinion gear. I ordered a replacement part and had hoped it was a simple matter of replacing it and off we go.
Unfortunately there are two counter rotating gears within the head, one for the pendulum motion and one for the cutting up and down motion. I know understand these gears need to be synchronized in order to minimise vibration.
Can anyone advise me how to do this. Are there any 'timing' marks or something?
The machine is now working, and Ive of set the two counterbalance weights to oppose each other as accurately as I can, however the vibration which remains, while not excessive, is undesirable and Im wondering if there is more to the alignment of the gears than what I have managed.
