Bulgarian is called an angular grinding machine. After a drill, this is the most common tool of home masters. Bulgarian enjoy both construction works, with plumbing and with different metalworking. It can be cleaned, cut off, shonds. But over time, the tool can stop working. How to fix it?
1
If you have at least elementary knowledge on electrophysics and mechanics, you can try to repair the Bulgarian yourself if not - better contact a qualified master. Otherwise, the tool can be confused. Attention: any repair of the power tool must be carried out by turning off it from the power supply. To do this, you will need screwdrivers - flat and cruciform, passage, knife, tester, possibly tape, alcohol.

If the Bulgarian does not work, then define a malfunction, moving from simple to more complex. First, check the availability of the current on the network and make sure that the plug is opened.

One of the most common faults is a wire fracture in the feed cable. It usually occurs in the place where the wire enters the inside of the grinder. Remove the instrument handle cover by unscrewing the screws with a cross-shaped screwdriver. Tester ring two wires. If it is faulty, replace it. Scrurts are better not to do, at the place of the twist the cable will break again.

With the handle lid open, look at the brushes and anchor collector. If you saw that the brushes were worn out, they need to be changed to new ones. To do this, open the two booster windows, and rejecting the spring, make a replacement. New brushes must be absolutely similar to the old.

On the collector plates can form a chalk or a nagar, and it makes it difficult to uniform pressing the brushes to the plates. Take the tweezers, watches, and drove the brushes from the holders, wipe the collector with alcohol. Alcohol is blews well with Nagar and South.

Check if the button is working, you need a tester. (Turn the button under voltage or homemade calls can be dangerous for your life). The button has two tokopropuscular channels. Disconnect the button from the chain and in the on-on state sound. First one channel from the entrance to the exit, then the other. If the button is faulty, replace the same. The repair of the button itself is not practical (small parts, deformation of plastics) and usually ends with anything.

If the reducer does not hear outside noise, you need to open the gearbox, unscrewing four screws. If the gear was worn out, replace it with a similar one. It happens, you just need to add lubricants or replace a new one. Old lubrication must be removed by gasoline. Use solidol, lithol, etc. for lubrication.

If the bulgaris fell turns and from under one of the brushes there is a large sparking, accompanied by a grain and smoke, then there was a breakdown of isolation at anchor. In this case, it is necessary to change anchor, although this work is not always profitable. But if you decide to change anchor, then open the gearbox and remove the gear, remove the brushes, remove the handle. Under the handle is the cover with the bearing container. Unscrew the screws and remove the lid. Now you can replace the anchor serviceable. Assemble in the reverse order.
We hope our advice will help you solve the problem with the repair of Bulgarians, saving time to search for a master and pay for his work.
