　 Repair of straight grinder
Â
First, unscrew a plastic nut on the position of the grinding head of the straight grinder. Then use a screwdriver to remove the 4 screws from the housing. Slowly pry open the shell, its shell is composed of two halves. It is generally easier to pry away from the position of the top plastic nut with a small screwdriver. There will be no traces. Open half, and the other half takes the shell and the movement shaft in one hand. The switch will come out. The inspection switch also showed no signs of scorching. At the same time also check the bearing wear.
Since the switch is good or bad when it is used, it is determined that the switch is in poor contact. So use a small flat-blade screwdriver to gently pry off the toggle plastic piece of the switch. Note that the screwdriver is inserted in the position of the toggle and the switch buckle, and the force is applied outward. It came out by pulling the buckle a little bit. At this time, you can see the circuit board of the switch, which is composed of thyristor and sliding resistor. It turns out that the poor contact is a long trace of the carbon film that has been used for a long time, and there is still a lot of dust. Finally, clean the dust and put two special oil drops on the carbon membrane, so that's it. Only in this case, the straight grinder should be adjusted as little as possible during use. Do not use this switch to turn off the power of the straight grinder. It is recommended to use an external switch or foot switch to turn off the power. In this way, the overall life of the straight grinder can be extended.
