How often should the oil in hydraulic tools be changed?
При стандартной работе масло рекомендуется менять не реже, чем раз в два года. При частом использовании инструмента масло нужно менять чаще. Периодичность замены масла определить не сложно – если пресс начинает качать слишком медленно, или рывками, то пришло время проверить и долить или заменить масло. При покупке гидравлического инструмента можно сразу приобрести гидравлическое масло «КВТ» для последующего обслуживания.
How long can a crimper work? How long is its life?
It is not possible to make an exact forecast about how long you will use the tool. A lot depends on the intensiveness of the work, the sizes of lugs that are crimped. In accordance with the international standards, the life of a hydraulic tool is from 5000 to 10000 of crimping operations. In reality, most of KBT hydraulic tools perform from 10000 to 30000 of operations during their life. Regular and proper maintenance is also important for longer life and more effective work. Change sealing rings and add hydraulic oil on a regular basis. The fact that we give from 3 to 5 years of guarantee for our tools says a lot about the operational resource of KBT tools.
Can dies designed for ПГР-300 be used for work with ПГР-150 СИП?
Yes. Models that can be sued with same dies are ПГР-300 «КВТ», ПГРс-300 «КВТ», ПГРс-300А «КВТ», ПГРс-300АМ «КВТ», ПГП-300 «КВТ» and ПГП-300А. You can also use the precise dies in sets HM-300 with all of the above-listed tools.
What sizes of lugs can be crimped with dies in tools ПГР-70, 120 and 300?
Dies of all these tools are designed for crimping lugs that correspond to the Russian standard (ГОСТ) and DIN standard. The quality of the crimping is very high, that is why these tools are so popular on the market. In case you need highly-professional crimping for special purposes, we recommend using precise dies HM-300 made by KBT, that were designed for particular lugs.
Can I use hydraulic tools made by KBT with a pump from a different manufacturer and viсe versa?
The main issue to take into account here is the type and size of a quick-release coupling. If the couplings in the pump and the tool match, you can use this combination for work. KBT quick release couplings have the following design details: thread M22 with a pitch 1.25 mm.
Can I adjust a pressure release valve by myself without any professional assistance?
Yes, it is possible, but please make sure that you take off the non-movable handle, drain the system, take away the rubber tank. You should not drain the pump, but you will have to disassemble some parts of it. Moreover, the correct adjustment of the pressure release valve demands particular experience and skills. Therefore, it is better to trust the adjustment to the professionals from the Service Center.
Could you please recommend what s better- mechanical tools or hydraulic tools?
All tools have their advantages. A lot also depends on the circumstances of use and frequency of operations. For example, you can you mechanical tools at any weather conditions. Hydraulic tools can be used in temperatures between -15 up to +50 °С. Mechanical tools do not demand so much maintenance like hydraulic tools. Sometimes it is easier and quicker to crimp a lug with a single handles closure of a mechanical tool. Hydraulic tools are better and more comfortable when you do a lot of regular operations, as the user does not apply too many efforts. The pressure release valve in hydraulic tools saves the tool from possible damage. It is better to make your choice basing on your particular needs and conditions.
Any works should be done only on a disconnected line. In case of extra need to work under voltage, please use special tools that are designed for work under voltage.
There are no such tools in KBT range at the present moment.
Some mechanical tools cost a lot more than hydraulic tools with correspondent functions. Why should I still prefer mechanical tools? Are there any advantages?
This decision depends on the particular conditions that are vivid only for a person who plans to buy and to use the tool for work. Mechanical tools can be used in any weather conditions and demand minimum maintenance, moreover, they work quicker than hydraulic tools. However, the user will need to apply physical efforts to work with mechanical tools.
