- - "continuity";
- - screwdrivers;
- - nail file.
Inspect the iron with the side where the cord goes. Locate the screws located on the back cover. Remove the bolts using a suitable screwdriver and remove the cover.
Check power cord and make sure that there are no fractures. Carefully inspect the cord in places of its exit from the plug and the body of the iron. Make sure the cord with "continuity". If the wire is not normal, shorten it to 10-15 centimeters - usually this is enough to resolve the problem. Again, test and reinstall.
Take a sheet of paper and a pencil and sketch schematically the connection order of the wires - it will come in handy when assembling the unit.
Remove the temperature control knob. To do this, take a knife, slide it under the handle and lift it up.
Inspect the iron and locate the screws securing the housing to the sole. Usually they are hidden under the filters, decorative caps or cover water containers. The location of the screws depends on the model of Bosch iron. Remove the bolts with a screwdriver. Remove the housing of the iron.
Check the temperature controller. It is necessary to rotate the control rod first to the left, then to the far right. If the rod turns too tight, use pliers.
Connect the "file transfer" for contacts by spinning the control rod, verify that the electrical network. If necessary, clean the contacts of iron with a nail file or sandpaper.
Plug the wire "continuity" to the thermal fuse and test it. If the bulb does not light, remove the thermal switch and short circuit the electrical circuit in the place of its installation.
If the electric cord, temperature controller and thermal fuse are OK, then blown ten. The heating element of the iron Bosch zavalova in the sole and, unfortunately, cannot be repaired at home.
Advice 2: How to disassemble the iron
If you have stopped to heat iron, do not hurry to throw it out. After all, the fault may be quite trifling. To correct an internal fault, the iron need to disassemble and inspect. In this article, we will consider the process of disassembly and repair of the iron in the details.
The iron case is usually difficult to understand. First, open the back cover where the power cord connects. The slots of screws holding the cover, can be very different. It all depends on the manufacturer. Sometimes you have to undermine a screwdriver, needle files, so it will fit.
After removing the cover, check the power cord. Ping it with a tester. You can also connect to the terminals on the iron cartridge with a bulb 220, and then insert the plug into the network. Lived often breaks the wires where the cord enters the body of the iron. Here follows a slightly shortened cord. If the plug and conductors of wires are OK, disconnect from the sole upper part of the iron to check the internal components.
When disassembling the housing, you need to find all the screws of the fastener. They can hide anywhere. Unscrewing the mounting screws, engage the latches that need to press with a knife or screwdriver. Remember that what is attached and in what sequence. Otherwise you risk not to collect iron back or not collect in full.
After completing all operations, separate the body of the iron from the sole. Check with tester heater (heating element, mounted on the edges of the soles), thermal fuse and thermostat. They are connected in series, so the problems should arise.
If you have no measuring instrument, check the fuse and thermostat through their alternate circuit cut the isolated piece of wire, the ends of which needs to be stripped. Include at this time the wires to the socket, but do not forget about the danger of electric shock. To prevent this danger, you can, if you do not touch the live parts of the iron bare hands. In the extreme position the thermostat is open. It is included with a distinctive click while rotating. When you open contacts you can clean them with a needle file or strips of sandpaper.
The irons usually blows the thermal fuse. And it can be short-circuited, the deletion of the electric circuit. Iron can work without a working thermal fuse, which is an additional protection in case the thermostat will be "sticky". Only in this case do not forget to unplug the iron from the mains immediately after Ironing.
And if the thermal fuse, the thermostat and the power cord is intact, the iron may be discarded or disassembled for parts.
Advice 3: How to disassemble the hammer drill Bosch
It happens that urgently need to disassemble the tool, for example, rotary hammer Bosch, and time in service are not, therefore, have to learn the skills of a master repairman.
You will need
For starters, examine the punch to detect visual defects. Vulnerable spot drill the plastic strip on the cartridge: it breaks down a lot, which leads to loss of retainers. To prevent this problem, it is recommended to use a long drill bit.
Punch start to disassemble from the top node. To begin, remove the rubber tip, then lock washer, then the head and the spring. Following this pull out the bulb.
All removed parts will be folded neatly (nothing should be lost, because then it will be impossible to collect the punch). After that, take the casing tool from the gearbox between the body punch and gearbox you should see a crack (3-5 cm).
Remove the switch by switching it to strike by drilling. Then remove the housing from the gearbox.
The power tool may stop working for different reasons. For example, cover the anchor or the stator. To resolve this problem, disconnect the drill from the mains, Unscrew its back cover has three screws, and then remove the cover. Check the condition of the brushes, after this the bell cable and the power button.
If suddenly detected the breakdown, inspect the cable to identify the reasons for the strong inflection. If the apparent cause of damage to the cord is not detected, loosen the cable and examine each core of the cable. Pull out the damaged vein, clean the part where was the breakdown, then ping cable to verify its integrity and collect the hammer.
Sign removed parts, because otherwise it will be difficult to correctly assemble the punch.
Frequently check the condition of the brushes, since the change of the brush is much cheaper than replacing the anchor. Each time you replace the brushes, lubricate the rear bearing (this will avoid overheating of the punch and its premature failure).
