Rotary hammer repair
You can carry out repair of the Kress puncher yourself. To begin, the tool should be disassembled. At the first stage, the lever is removed, which provides switching. It is important to exercise caution, otherwise the repair will entail the destruction of parts. In some models, the cartridge is not removed, so it remains to be disassembled. To remove the rubber gasket, use a flat screwdriver.
Now you should do the snap ring. The Kress puncher, which you can disassemble yourself, has a cover, removing which you will see that there is a fixing unit in the barrel. Disassembly must be done in order, starting with a metal ring. After disassembling the cartridge, you may notice that the rubber gasket has worn out, so dust gets inside the tool. Parts should be cleaned and replaced with anther. Dirt will also penetrate if the cover is deformed. This will not affect the work, but the details will wear out faster.
If you notice that the circlip is loose or worn, it must be replaced. When the ball is worn, it is also changed, but on the condition that the diameter remains the same. Otherwise, the cartridge will fail permanently. Before disassembling the Kress puncher, it is necessary to take care of the presence of lubricant. At this point, the guide washers should be fixed in the holes. Sometimes the guide balls wear out. If wear is critical, a replacement should be made. The most stable part is a conical spring. However, with prolonged use, it may become deformed. In this case, it must be replaced by deploying a smaller vertex to the gearbox. The cartridge is assembled at the next stage, and after that it is possible to assemble in the reverse order, lubricating the end of the drill.
Gearbox repair
Repair of the Kress rotary hammer may include the need to repair the gearbox. If there is no suspicion that the engine has burned, then the gearbox should not be dismantled. Pull the housing along with the needle bearing from the barrel. A malfunction may occur in the fact that the bearing does not come out, this indicates the development of a seat in the housing. In this case, the housing changes. It is also necessary to replace the part when the shaft bearing is loosened.
If you notice an oil leak, you may need to replace the oil seal. Quite often, the cause is an excess of lubricant. When the Kress rotary hammer repair is done by yourself, you should ring the cord. Damage to it may result in equipment shutdown. If the cord is in order, then you need to check the stator and anchor. To do this, the cover is unscrewed from the back. When disassembling the upper assembly, it is necessary to dismantle the housing and the switch. It is important to periodically lubricate the drill shank, otherwise the firing pin and o-rings will fail more often.
Basic faults and solutions
If you have a hammer drill, then it is important to have a tester as well. Use it to simplify the troubleshooting task. Otherwise, all electrical parts of the device will have to be inspected alternately. When the operator is faced with the problem of refusing to turn on the tool, he must conclude that the wire was broken. Quite often, the cord is damaged near the handle. The cable in this case must be replaced or shortened.
If the gap occurred in the middle, it is recommended to strip the cable from insulation and connect the parts by insulating the cord. Failure, expressed in poor contact of the trigger elements, sometimes occurs due to burnout or oxidation of the contacts. Items must be cleaned or replaced.
If there is a breakdown of the quenching mechanism, then a large load on this part of the mechanism can lead to this. The burned parts should be replaced, and if there are none, then the engine is connected directly. This method of troubleshooting can increase engine wear by several times. Use this technique is necessary only in extreme cases. If you notice sparks inside, then they can be a consequence of the fact that the brushes are not tight enough to the anchor. This malfunction sometimes occurs due to wear on the brushes or when moisture gets inside the case.
If you notice that smoke has gone out of the punch, problems with brushes can also indicate this. From time to time it is important to carry out an inspection, since when they are abraded, wires appear on the working surface, which causes smoke to appear. Sometimes such a malfunction is also indicated by a motor jam. The winding at the same time begins to heat up and smoke. It is necessary to inspect all the elements, and if the problem is in the brushes, then they need to be replaced.
