I've had an Automate for a little over a year and haven't had to do anything to it. However, when I first bought it (new but from a reseller), many of the components inside were loose and needed tightening. I added the foot control switch (not a MEC option) and it's been smooth sailing since.
I don’t have a huge number of rounds thru mine - I think I did have to replace an inline fuse at one point. Quite frankly, if something went wrong with the electronics I’d probably be out of luck as I no skills for those things.
I have well about 100,000 rounds on my automate. Other that blowing the inline fuse one time during a collision it has not required anything.
Here are some maintenance tips for the motorized base: Keep the unit clean and free of debris. Wipe down the surfaces with a clean cloth and use compressed air to blow out any dust or dirt that may have accumulated. Check the bolts and screws periodically to make sure they are tight and secure. Apply a light lubricant, such as a silicone spray, to the moving parts and the motor shaft to keep them running smoothly. If you notice any unusual noises or vibrations, stop using the machine immediately and inspect it for any signs of damage or wear. Follow the maintenance instructions provided in the user manual, including any specific recommendations for the motor and electrical components. By following these simple maintenance steps, you can help ensure that your MEC Auto-Mate continues to operate reliably and efficiently for years to come.
