punch, makita, perforator, malfunctions

The procedure for repair/replacement of the power button on the perforator Makita 2450 is as follows:

  • We disassemble the electric part of the tool. To do this, unscrew the three mounting screws on the back of the handle with a cross blade and remove the plastic cover.
  • Next, you need to push the brushes and extract the TG813TLB-1 switch itself.
  • To disconnect the switch, it is necessary to remove all the wires from it. Network wires (brown and blue) are attached with a screw clamp and there are no problems with them. To throw off two wires, it is enough to loosen two screws. The remaining wires are mounted on self.Loading connectors, and to extract the wire, you need a spoke or awl, which are inserted into a special hole and open the clamp. Similarly, all wires are recovered sequentially. To carry out the repair, it will not be superfluous to have on hand a scheme for connecting the perforator button, so we strongly recommend that you draw a conditional circuit before removing the wires or take photos on a smartphone so that there are no questions when connecting a new button.
  • Connecting a new button. The wires are simply inserted into automatic clamps to the stop, the network wires are fixed with screws.
  • Next, you need to install the button in the landing hole, return the brush to the place, install and fix the rear cover of the handle with three screws.

Useful tips

Often, even professional equipment quickly fails. This is due to the operation of the tool with a significant overload of the electric motor. The power unit should not be overheated, it is periodically necessary to do technological pauses. Sometimes a serious breakdown of a perforator is a consequence of a careless handling of a tool during operation or during storage.

After each use, it is necessary to carefully clean the perforator from dust. With a soft cloth or a napkin, not only the housing of the power tool should be wiped, but also the ventilation grooves.

It is regularly carried out by inspection of coal brushes, which are a responsible part of the electrocope. They conduct current to the collector and gradually wear out during operation and require replacement.

Do not buy non.Original components of dubious quality, which can lead to more significant breakdowns.
