MEC Auto-Mate Assembly Manual
For MEC 9000G/GN and 8567 Grabber Series 
Thank you…
We really appreciate your support of our product
line. But our commitment to you hardly ends here.
We won't be satisfied until your new MEC AutoMate exceeds your expectations. . . year after year.
We encourage you to take your time as you begin
to use your new MEC Auto-Mate. Carefully review
this manual to learn the operational features and
considerations for safe operation.
Your MEC Auto-Mate is a machine that if used to its
capability will speed the process of reloading, and
for those with physical impairments, will allow you
to once again be able to load your own shot shells.
But like any machine you need to thoroughly
understand it to get the most out of it.
That's where we come in again. If you have any
questions, comments, or suggestions we want to
hear from you. Give us a call at,
800-797-4632
8AM - 4PM CST Monday-Friday.

Safety Information
General
The MEC Auto-Mate is a unique product in that it is designed to work in conjunction with equipment
and reloading components designed and manufactured by Mayville Engineering Company, Inc. It is
therefore of up-most importance to read, fully understand, and strictly follow the operation, user, and
safety information for ALL the equipment and reloading components that you will be using in the
reloading process.
Millions of men and women reload ammunition as a hobby, or because the cost savings allow them to
enjoy shooting more often. You should always reload so that the safest and most accurate loads on
the shooting line will be yours, and always remember that to become or to continue to be a safe
reloader, you must be careful at all times.
Checking powder and shot charges with a reliable scale is a must, and will disclose if you have any
variations in weights. Adhering to loads recommended by the powder manufacturer is a must.
Always wear safety glasses!
On your machine and in this operator’s manual safety labels and statements contain the words
DANGER for the most serious hazards and CAUTION to call attention to safety messages.
DANGER
CAUTION

Electrical Grounding Instructions - This machine is equipped with a three-prong
(grounding) plug for protection against possible shock hazards. If you encounter a
two prong receptacle, contact a qualified electrician and have the two-prong wall
receptacle replaced with a properly grounded three-prong wall receptacle in
accordance with the National Electrical Code.
Machine is designed to operate on a separate 110 to 120 volt. 15 amp.. 60 cycle line.
(2) Avoid contact with energized circuits.
