High-grade brand power tools, because of the long life, as long as the maintenance is not too hard and hardworking, the brush is often afraid to use the broken rotor to check the damage of the carbon brush. Such as: the new machine uses more than 8 hours a day to change the brush once a month (must be a good brush, otherwise it will affect the life of the rotor > butter also has a grade, preferably green butter)! Electric drills, marble machines, angle grinders, etc. only need to pay attention to the brush, because those tools are not damaged by lack of oil, only because of excessive use, such as the bearing is broken and there is abnormal noise and continue to use.
The most important thing to pay attention to is the electric hammer and electric pick, the electric hammer plus butter, the electric pick and the oil! Staying depends on the level of your butter. Good butter doesn't add once in half a year. If it's ordinary butter, add it once a month and half a month, don't add it more, lazy, add it once a month, a little more. Look inside the dry bar, add the mineral water bottle cap two caps of oil, the hammer head to the ground for about 30 seconds, electric shovel mainly add oil (design principle, the oil will enter the oil pipeline when the motor is running), 4 3 parts of oil, 1 / 4 of butter, is the site is not afraid of electricity leakage, dirty soil can be added to the machine, no harm to the machine, the premise is that no matter how you place it, stand up, point down, such oil It will only leak in front of the cylinder and will not leak into the motor. In the gearbox, you can add it once every 3 months. Don't add more at once. There is not much oil in it, and the butter is more leaky.
