Grinder daily inspection is very important

 First check the power outlet, plug the power cord from the presence or absence of oxygen loss, breakage of the Department, if not you can plug in the power test machine does not rotate when the motor is energized with Light toggle wheel hand piece can be rotated, can be concluded that the aircraft has a two-start capacitor failure due to capacity. In this case generally only for new products. Pellet mill is that power does not rotate, apply force to be able to turn it inside the motor emits a weak current sound, slight leakage is due to start capacitor. If the current sound too large, the motor does not start, start capacitor circuit judge is due to (motor coil shorted need professional repair). In the absence of professional equipment The case, first remove the capacitor (4UF/400V), the two leads were inserted into the mains zero and FireWire jack to charge the capacitor, and then remove the two cited Line short-circuit discharge. If the case can send sparks and there is a loud "pop" sound, indicating that the capacitor can be used; if sparks and oil refinery, indicating capacitor Capacity has declined to be renewed, or add a small capacitor can be. If the capacitor is shorted can not use this method has been damaged and must be with the same specifications for new products Conversion can be repaired. Then there is a class of small high-speed grinder, the general quality of this grinder is very hard to damage, and daily maintenance becomes more important To, the following is kind of mill maintenance priorities. Check bearing lubrication is good Check that all fasteners are tightened. Check the drive belt is properly installed and in good condition, if found damaged belt should be replaced when the belt or slots There is oil on the wheel, the application promptly wipe clean cloth. Check the protective device is good, if found unsafe guards phenomenon, should be immediately removed. Check whether the damaged materials or other debris cavity, if it should be cleaned. Check the hydraulic machine from the top or from the top screw head is returned, adjusting pads are Whether it is properly installed and pressed.
