In addition to the above, the insulation resistance should be measured and should not be less than 7 megohms (measured on a 500 megohm meter). More care should be taken during the rainy season. If it is not operated for too long, it should be dried if its insulation resistance is less than 7 megohms.(1) Carbon brushes should be checked regularly and replaced in time. After replacement, check whether the new brushes can move freely in the brush holder. See that the armature rotates correctly, then let the motor idle for 15 minutes to match the contact between the carbon brushes and the commutator(2) Keep vents clear and free of dirt.
