I just bought and received a brand new OF 1400! It's killer, but I need to know if the noise at the start of each pull of the trigger is normal, or if there is something wrong with mine.  The noise sounds almost like a ratchet noise, or like something is loose. Only lasts for maybe a second until the router gets up to full speed, then no noise at all. Any help would be appreciated!

Thanks
 
Well, I can't hear your router. [tongue]

That's why I shared the video so you could compare.

If you want a second opinion you can call when you're with your router and let us hear it over the phone. There shouldn't be what I would describe as a rattling sound.

You could also go to your dealer and compare it with another one in person and exchange it if necessary.
 
Ok. Thanks for the help. Let me see if I can get an accurate representation of what it does via video and I'll share the link.

Thanks
 
Here is the link to the video:

You can hear it each time the router starts, sounds like a rattle or something spinning around that maybe shouldn't.

Thanks
 
Good video of  the sound. I've had this router for about 8 months now and never noticed the same vibration like sound that you are getting. I will go and try mine and let you know.
 
I just checked mine out and I get the same noise upon start up. It sounds like a bees wing hitting a piece of paper. I've never noticed it before until you pointed it out. I don't think it's anything wrong. Probably works as designed. I've used mine for many miles of routing and have never had an issue. It's  a great router. Maybe a call to Festool service might explain the noise. When you find out let me know. Cheers, JC.
 
Probably just the brushes an armature.  Mine sounds like that too, I think.  Had it for years and it is not broken yet. 
 
The sound is just a side effect of the soft start function of the motor. It's a similar reason why the TS saws make a growling sound, except they have the added noise of gear backlash, which is even more noticeable.

To control the speed of the motor, the MMC electronics send out pulses of electricity to the motor--constantly turning it on and off. During the soft start period, these pulses are short and spaced apart enough to be slightly noticeable. It continues to pulse the motor even when it is up to operating speed, but it is far less noticeable because they are closer together.
 
Thanks for the explanation Rick. Makes perfect sense. Cheers.
 
Thank you for all the help everyone! Love this group! Helps a newbie like me get by!
 
Just a suggestion to rename your video or put something in the description or comments for others who might have the same concerns.

Thanks.
