I hate to be the first one to post a problem because the people that love the product come out of the woodwork. I have the same issue with two different products, the battery forced rotation and the battery DA. The forced rotation is the absolute worst, so bad I ended up putting it away yesterday and using something else. And I had my son take a video to document the issue. Here's what I've found.
The battery used or the battery charge doesn't matter AT ALL. I have two tools and four batteries. I have both chargers mounted in my trailer, so batteries get immediately charged when they're dead. The problem is with the tool(s) themselves.
1. Forced rotation started with this problem from when it was new and it's actually getting worse. You start polishing and hit the trigger lock. After the unit warms up a little, usually just a few minutes of polishing, it will just stop. There is absolutely no way to get it working again until you remove and reseat the battery. When it first started happening, that would usually work every time. Yesterday and the day before I had two big jobs. I was probably averaging having to remove and reseat the battery 5-8 times before it would work again. The most maddening part? As if that's not enough. It will finally work when you pull the trigger and then you let the trigger go and move the polisher to start working on the vehicle and it's not working again. I swear yesterday I almost threw it into the street. Again, I have video.
2. The DA is similar except that it doesn't typically stop working while it's spinning. You let off the trigger, apply some more product and squeeze the trigger again and NOTHING. Again, remove and reseat the battery 1 or 2 times does the trick, but I'm sure that this tool will get to the same point as the forced rotation because that one got progressively worse.
I purchased these tools around New Years, received them about a week later, so they have very little use on them. For the $1000 I paid, I'm really pissed off about the usage I'm able to get out of them. I literally decided it was more trouble than it was worth yesterday after polishing the trunk lid of a car and put it away. I really want to like the product and I can see how it's so convenient when it works properly but as is right now I can't use them or at least the forced.
I'm not a hobbyist user my tools get used to all day every day but there's no way I should be having issues with a brand new tool less than three months after purchase. Hell, I've got a cheapo maxshine 21 that I use for machine claying and waxing and as a backup that has been used for thousands of hours, been dropped several hundred times and still works like the day I bought it.
