Greetings Bruce and welcome to the router forums, we are glad to have you join us.
9 amps is a little on the shy side, mine are 11 and 12 amp routers but you can still get by with what you have remembering that burning is usually an indication of dull or dirty bits, too slow a feed rate, taking too big a bite or a combination of the above. Try taking a smaller bite with an increased feed rate after cleaning your bits (you can get a cleaning solution from Rockler or other on line supplier or maybe someone on the forum has a solution that works). BTW you can tell if a bit, or blade for that matter, is dirty by any build up on the cutter that won't just brush off. I am sure you will get feed back from others
