CXS Torque Clutch Behavior vs. Description in the Manual
« on: January 06, 2013, 04:32 PM »
Hey Festool,

I was perusing the manual for my new CXS drill/driver and came across this bit in the US manual:

Page 12, Settings | Fastening

Adjust the torque accordingly at the torque thumb-wheel 1-1
Position 1 = low torque
Postion 12 = high torque
The machine switches off when the present torque is reached. The machine only continues running when the on/off switch 1-6 is released and pressed again.


While the 1 through 12 values of the torque adjustment are correct, it is not a thumbwheel, but a collar (pretty obvious). However, the CXS, at least the sample I have, does not shut the motor off when the torque clutch starts slipping. I assume the manual is incorrect as it has been made pretty clear on this forum that the CXS has a completely mechanical torque clutch, not electronic, and not even electronic-assist.

Two future improvements for the CXS:

1) If you must stick with a brushed motor to meet design requirements, at least consider adding the electronic-assist torque clutch which shuts the motor off once the clutch plate spins once (use a magnet or optical sensor for this). Granted, the "road feel" feedback to the hand allows one to use the clutch as backup, so it's not that much of a big deal vs. one of the more massive drills.

2) I would like to see a simple capacitor added to the LED so it stays on then fades out a couple seconds after releasing the trigger.. that is a nice feature of the C15.

Those are minor nits to pick on an otherwise fantastic little drill/driver. It's like a Mazda MX5 Miata of Festools: simple, affordable, and becomes an extension of your body. Perfect for its intended usage and a nimble runabout, and a great complement to one of the larger machines.

I don't have the printed version of the manual to look at, but the online manual doesn't say that. It's possible there was an error in an earlier version of the manual. As you can tell by the word thumb-wheel, these are translated in Germany and sometimes the language is less-than-perfect English.

Thanks, Shane.

Adjust the torque accordingly at the torque thumbwheel

[1-1]:
Position 1 = low torque
Position 12 = high torque

The machine switches off when the present torque
is reached. The machine only continues running
when the on/off switch [1-6] is released and
pressed again.
