The pulse tool requires regular maintenance to ensure the tool operates at optimal performance. The type of routine maintenance and the frequency is dependent on the application and how the tool is used. The pulse tool requires preventive maintenance like oil changes and have the parts inspected periodically. Regular oil changes will increase the life cycle of the tool, reduce maintenance costs and allow the tool operate properly.
Removing and adding oil into the pulse unit requires a syringe and vacuum tank system. The syringe is used to remove the old oil within the pulse unit. Then the pulse unit is placed inside vacuum tank, which is used to extract the air first. While inside the vacuum tank the pressure of the tank is released, which will cause the pulse unit to absorb new oil. This process will fill up the pulse unit completely. Then a syringe is used to remove any excess, the withdraw process.
This video is example of one type of vacuum system. Vacuum tanks are different in size, capacity and configuration. There is no standard size or capacity required for servicing the pulse units. Some vacuum systems perform the entire process in one step and other systems might require multiple steps to perform this process. Please consult the manual for your vacuum system first.
