Kapex and Midi Vacuum
« on: June 07, 2017, 01:32 PM »
Hi.  I am thinking of purchasing the Kapex 120 and wanted to make sure it was compatible/recommended for use with Midi Vac.   I have read about some Kapex problems being attributed to power issues.  Some have suggested that plugging into the vacuum could reduce the power enough to cause problems.

Just want to make sure it won't cause any issues.

The midi vacuum is compatible with all festool tools that have a power consumption of less than 2400 W. Festool limits the CT outlet to 3.1 Amps for all non Festool products. There is an official description in the forum here.

Festool CT Dust Extractors are designed to be used with every Festool product in normal working environments. You should be fine running a KAPEX with a CT MIDI.

The only thing you can know today is what has been stated above.  But to more specifically address your question, there has been a lot of speculation about the Kapex issues, but no confirmation of an issue from Festool or a known cause or even an established pattern among users, so you would be chasing your tail trying to ensure you don't smoke your Kapex.  I use mine with a Mini and they are a great pair and highly portable!

I've been using my Kapex with a dedicated Midi for years with no issues. I swapped out the standard hose for a short bigger diameter hose and the dust collection improved.

I found the letting the dust collector run for a few seconds before beginning the cut improved dust collection. I also move the saw through the cut listening for any signs of the saw bogging down and acting accordingly. A slower cut helps dust collection.

You probably know to let the saw come to a complete stop before lifting the head to reduce the chance of throwing the cut off. I use a zero clearance insert I bought from Betterley (not sure about spelling). It helps with making a cleaner cut.

I know that here are many negative posts about the Kapex, but mine has been flawless. It was perfectly aligned out of the box. I did have to adjust the lasers.  By the way, find the laser Allen wrench that Festool hides somewhere in the box.

I bought the Festool wheeled stand and like it a lot. I don't often move my Kapex, but the wheeled stand works well when I have to.

Even the guys with smoked Kapexes would tell you they liked theirs a lot and they were flawless too...........right up until the time they smoked. 

The problem most people have is the smoking occurs after only a couple years of what they consider normal use. The same use they put on other saws lasting 10+ years.

So what you're really rolling the dice on is whether YOUR kapex is going to last more than 3 years without dying and whether your comfortable with the steep premium you'll pay for the features in exchange for that risk.
