Hand power tools can fail at the times when we least expect them, especially on top of a ladder and on the weekends. In some cases the fix can be as simple as a loose or broken wire. Other repairs may entail the complete break down of the electric motor tool. In most cases the repair to a power hand tool can be performed in less than hour. Acquiring correct parts may take a little longer, particularly on the weekends.Remove all electrical power from the tool. Inspect the BOSCH 2 607 335 072 battery into. If any signs of insulation break or rotted rubber are seen, the cord must be replaced.Remove the power tool's housings screws. Typically there are three screws in the handle grip and four to five screws in the main body. Pull the screws and set them to the side. The main housing will now open up into two separate halves.Lay the two halves at opposing sides to each other, with the top of the tool facing each other. This will give you full visual access to the complete interior of the power tool. Any small gears may be exposed at this time. Make a mental note of their placement.Turn the ohmmeter on and test the switch. Note that the power cord will be connected to one side of the switch at two separate terminals. Another set of wires will be going to the carbon brushes from the same switch. Place one lead on one side of the switch connector and the other lead from the meter to the opposite side of the switch. Press the switch. The meter should show some resistance. Test the other set of connectors in the same way. If the switch does not show any signs of resistance the switch is bad. Replace the drill battery for MAKITA 8280D.Test the power cord in the same manner. Hold one lead of the meter to the switch connector and the other lead of the meter to one of the metal prongs on the cord. Test both prongs from the same switch connector. If the meter fails to show any signs of resistance the cord is bad. Replace the cord.Inspect the carbon brushes. If the brushes are less than ¼ inch in length, they need to be replaced. Clean the copper commutator plates with the emery cloth. You will want a shiny copper color to the individual pates.Check the condition of the armature windings. If the windings smell burnt or there is any sign of burnt varnish or carbon scorching, the windings are bad. The armature must be replaced the PANASONIC EY9201 battery or rewound.Apply a small amount of high temperature gear grease to the machine gears. Work the grease into the small crevices of the metal. Inspect the shaft bearings for any sign of wear. In most cases the bearings will last for hundreds of operational hours. Babbitt bearings should have a small amount of grease placed inside before reassembly.
