Question: how to take apart and clean
Document: If you juice greens all you need to do with the CHAMPION is wrap your greens and a carrot together and it will work fine and it does not jam up when juicing celery or anything else. Their are some other masticating type juicer that run slower and I have looked at these but they are harder to assemble and take apart and clean. And the juice quality is not any better. Also the CHAMPION JUICER dose not oxidize the juice and all juicers have about the same yeild.
The screen holder / expulsion piece is a bear to slip on the processing tube. After years, i could never put this together, or take it apart, without husband. That is ridiculous! You have been warned
At first it juiced well, but then it started to leave a lot of pulp. It does not take that long to clean, I noticed how much the vegetables leave a ton of stain behind on the machine. It is a lot heavier than expected.
OMG this is the best thing we ever invested in. A Thank you 'shout out' to the makers of the Champion. We love juicing now that we own a Champion. Clean up is a snap, tho trying to fit the screens at first was a tad tricky, its easy to operate and easy to take care of. Its simple and very effective. We picked the commercial heavy duty unit and oh are we glad we did! The motor is powerful but quiet.
I have had this juicer for about 9 months and works a lot better than my old CHAMPION. 90 percent of the people that juice want a juicer thats easy to assemble and easy to take a part and clean. I think the CHAMPION is buy far the best. also the CHAMPION will juice anything and not jam up, it will also make the best banana sorbet or berry fruit sorbet. Centrifugal type juicer can not do this and they can't juice a banana.
The only two major disadvantages I see from buying the Angel is, apart from the price, I heard (from discount juicers on youtube) that the company is a bit dodgy, and the screens tend to break (and are many hundreds of dollars to replace) and the screens are not covered by any of the limited warrenty.But as I have not worked for over 4 years, I can't really afford the Angel.
I can do carrot juice with the carrots right out of the refrigerator and no warm up. The machine handles cold veggies very nicely. The "shoot" that you put the veggies into is wide enough for those bigger carrots that you don't have to take time to cut them up first. My vegetable preparation is very minimal. The cleanup is very quick. I always hand wash and dry the pieces to insure they fit properly. I have never had any problems with the machine.
...after only one week, I contacted Champion. I was told to ship it back for re-painting. I then wrote to ask how long this would take. THREE WEEKS!. I then asked if, because it was new and I had paid full price, could this be expedited?I have not heard back from Champion. Great juicer, lousy customer service, and in my next posting I am going to name names...
It does take a little muscle to hold the screen down while you are putting the machine together so if you are 80 you might want to get a different juicer. It has a safety feature that if you don't have the machine put together properly, it will not turn on. I find that extremely helpful because I tried a Jack LaLanne juicer before this machine and didn't have one piece put on exactly right and the machine started up and broke the piece quickly before I even had a chance to turn the machine off.
this juicer is very powerful yet is quiet to operate but the best part is that the clean up is literally rinse and go!
Answer: I take it that the question is about the general removable parts and not the actual body of the juicer--where you have to get screwdrivers and stuff.  Okay, so, there is not much to this, actually, but what you do is turn off the machine, unplug it and then turn the feeder tube--what I call it--a quarter turn either clockwise or counter clockwise (not in front of my juicer, so can't remember off  hand) and then pull out/off the feeder tube.  Then, the main grinding mechanism, the thing that turns, is taken off by wiggling/wrestling counter-clock-and-clockwise while continuously pulling.   I use a common kitchen towel to grip the grinding mechanism, just to protect my hands from the metal teeth, there.  When the juicier is not in use, I place the grinding mechanism back on the shaft, but before I do, I use Crisco (vegetable grease--not oil), so that the grinding mechanism slides off easier.  If you have used your juicer without placing grease on the shaft, you'll have a bit of a time wiggling the grinding mechanism off, but it will be possible, just use a bit of finess.  The shaft should be greased each time the juicer is stored after use, which means the thing should be cleaned after each use.  If your in a restaurant and you use it all day long, then clean it about twice a day and regrease the shaft.  Any grease you used should be edible food grade, like Crisco vegetable grease.
