Berkel 827 sharpener not working properly

old food slicers used to have an oil stone that was held against the blade as it was spinning
worked a treat so you could do the same thing
only need to do it for about 30 seconds

If its an an ac unit (i.e plugged into the 110Vac wall outlet) and the switch is the on/off switch, it doesn't matter which one goes on which terminal.

1 of 2 problem exist, you need new stones, or the depth of your sharpener needs to be lowered to compensate for blade wear

The website says to check and make sure its not jammed with pencil lead or something else. unplug it take the shavings bin out and flip it upside down so you can look into the sharpeners. Rotate them by hand till you can see the open side of the blade then use a unfolded paper clip and slide it in the path the pencil would usually take. This should knock anything loose the would be jammed in there. If it passes through to where you can see the point you should be clear. If you didn't dislodge anything or it still doesn't sharpen but the blades spin when you try to use the sharpener, then there is a tab that can get jammed back that needs to be in the foreword position. The tab is located where the tip of the pencil would point if it was actually being sharpened. if you run the paper clip through the machine (just like when trying to dislodge something) the tip of the clip will touch the tab. make sure its not jammed back (away from the opening/pencil) it should be as far forward as possible for the blades to engage. I hope this helps! This has been jammed many times by pencil shavings or gunk on my wife's (elementary school teacher) pencil sharpener.

collee; take the blades to a machine shop or a small engine shop they will be able to sharpen them.

I believe you mean to say a 'reel' mower. Normally and old fashoined push (non-engine powered) mower.

Most consumer reel mowers do not need to be sharpened. They do however have a knife bed that occasionally needs to be adjusted. It should have the thickness of a regular piece of notebook paper between the blades and the knife bed. (that is really VERY close) You can buy 'lapping compound' from an automotive parts store, and apply that to the bed knife, and then rotate the blades to provide a precise fit for all blades.

Commercial reel mowers, such as those used on golf course equipment are however sharpened normally once or twice a year. It requireds dismantling, and many courses send their blades to a central location for golf equipment, where they are placed on a computer operated sharpener for precision grinding. This cost several hundreds of dollars just for the grinding.

The stone that sharpens the back bevel is used for more time, but use grind for minimal amount of time, 30-40 seconds sounds extreme to me. The stone for the top surface of the blade is only pressed briefly to remove the slight burrs from sharpening on the back side of the blade.

sounds like the angles have been cut wrong on the bits or you are drilling too fast

Maintenance (excluding the power plant) Your primary maintenance concern with chippers and shredders is their knives. You can re-sharpen chipper knives, whereas you can reverse shredder flail-type knives when dull but you can not re-sharpen them. You must sharpen chipper knives with special sharpening equipment because they are made of high-carbon steel. Maintaining sharp knives can lengthen their life and the life of the machine by keeping power requirements low. An over-dulled or chipped chipper knife will need extensive sharpening, which will remove a large portion of the blade. This obviously will shorten its life. As soon as a blade is slightly dull, you should sharpen it to minimize the amount of blade-material that you remove. All knives need sharpening at the same time to keep them in balance-even if only one is worn or chipped. Also, you must use matched sets to keep the knife the same distance from the anvil for proper chipping and feeding. After removing the knives, clean the area where they are fastened with a wire brush to make sure they will align correctly. Be sure to torque the knife bolts to their proper specifications. You will need to examine the anvil and be sure it maintains a good, square edge. Occasionally, you may need to remove and sharpen it.
