Rotary hammer repair
Repair of the Interskol punch can be carried out independently only after the expiration of the warranty period. The task of eliminating mechanical damage is more complex than when the electronics fail. Immediately establishing the cause of the breakdown can be quite difficult. First, you should visually inspect all the details, and after the breakdown is detected, fix the problem.
If you are faced with the fact that the device turns on, but does not hammer, then a failed switch could lead to breakage. The malfunctioning fingers of the switch may indicate a malfunction. They are constantly in contact with rotating parts, and this becomes the cause of wear. However, sometimes it happens that the sprout of the retainer, which holds it in the gear case, fails. In this case, the mode starts to switch spontaneously.
If this problem does not bother you, then there is no need to change the lock, because the punch will work. However, if you decide to repair the Interskol rock drill, you will need to replace the switch. If no suitable one is found, and the work cannot be stopped in any way, then the worn part can simply be turned over 180 ° C.
This approach will continue to work. As for the cartridge, this part of the mechanism is subjected to the greatest loads, this sometimes becomes the cause of breakdowns. If you encounter such a problem, then the cartridge must simply be replaced. You can extend its service life by the method of preventive care: cleaning from dirt and washing with gasoline from dust.
Methodology
The Interskol P-26 / 800ER 2 puncher has a hammer and a compressor ring. Failure of these elements can occur due to impressive loads. If you encounter a breakdown of this kind, then the only way out is to replace the node. When the gearbox fails, it is first dismantled and checked all the details. The most vulnerable spot is the bearing. It must be checked for integrity. It should be replaced if such a need arises. But the reason can also be covered in the seat. When it is developed, it begins to hold the bearing poorly. The punch body itself will have to be replaced in this case.
Quite often, gear wheels also become unusable. Having examined them visually, you can understand whether this is so. It is impossible to repair this part of the punch, it will need to be replaced. The Interskol P-26 / 800ER 2 puncher may run into an oil leak. This happens very rarely. But if it happened, then you just have to replace the oil seal, which is located in the neck of the case. The rotary hammer can work intermittently and with the ingress of dirt. This is indicated by rattle and crackle. In order to eliminate such a problem, from time to time it is necessary to carry out cleaning and lubrication of the internal cavity of the perforator. It is important to use the same type of grease without changing it throughout the life of the device.
User's manual
The Interskol P-26 / 800ER puncher should be checked by the method of trial inclusion in the store. Start of operation should be accompanied by a safety check of the workplace. It must be kept clean, it is important to ensure its good illumination. If the workplace is poorly lit or cluttered, this can cause accidents.
In no case should an electric machine be operated in explosive atmospheres under conditions that may include the presence of flammable dust, gases and liquids. This requirement is due to the fact that the operation of the device is accompanied by the generation of sparks, which can cause ignition of vapors or dust. The plugs should fit perfectly into outlets. They should not be changed on their own.
Manufacturer's recommendations
Adapters are not recommended for machines with a ground wire. It is important to eliminate the effects of rain on the electric machine. It is not recommended to keep it in humid conditions. If moisture gets inside the case, then this can cause electric shock. The concrete punch described has a power cord, which must be handled with extreme care. Do not use it to drag the tool and remove the plug from the outlet. The following must not be affected by an electrical device:
- sharp edges;
- oil;
- heat;
- moving parts.
The risk of electric shock increases if the cord is twisted or damaged.
Precautions for the operation of the punch
Using a percussion machine, hearing protection should be used. It is important to remember that carrying out work can damage the hidden electrical wiring. That is why the tool must be held by insulated handles during operation.
If contact with the wiring occurs, it may result in a fire or electric shock to the operator. A concrete puncher should be used only after using a metal detector you find hidden engineering networks by the type of electric, steam, gas and water pipes. An additional handle must be used when working. She is included. The hammer must be held with both hands in a stable position.
It is important to remember that the tool can jam if its working parts get into large fragments, stones or reinforcement. The equipment will react to a sudden jamming by a back strike, this can cause loss of control over the device. If the working tool is stuck, it must be turned off immediately. It is possible to release the punch from the hands only after the engine has completely stopped.
Service Features
The characteristics of the Interskol P-26 / 800ER 2 rock drill were presented above, however this information is not the only one that you should familiarize yourself with if you decide to purchase a similar model.

For example, you can buy a push-button switch for 1260 rubles, while carbon brushes will cost the consumer 450 rubles. Manufacturers advise using original spare parts for the Interskol P-26 / 800ER punch. Thus, the rolling clutch will cost the buyer 2100 rubles. As for the gear case, it can be bought for 1820 rubles. The piston sleeve costs 1250 rubles, while the stator of the electric motor costs 990 rubles. If necessary, replace the anchor can be purchased for 1390 rubles.
Conclusion
About how to make the choice of a puncher was discussed above. However, it should be remembered that it is important to pay attention also to some other features. For example, the impact energy. If you have a light model, then the impact force of the punch will be approximately 2 J, while instruments of a more serious class can hit with a force of up to 15 J.
Choosing a puncher with higher impact energy, you can provide the possibility of making holes of larger diameter. For some consumers, this feature is paramount. If this value is small, then the device will not work as efficiently.
