INSTRUÇÕES DE MANUTENÇÃO
This section describes maintenance work which should be carried out periodically. The operational safety and life expectancy of the filter, and
whether it is ready for use, depend to a large degree on regular and careful maintenance.
- Spare parts must fulfil the technical requirements specified by the manufacturer. This is always guaranteed for HYDAC original spare parts.
- Keep tools, working area and equipment clean.
- After disassembling the filter, clean all parts, check for damage or wear and replace parts if necessary.
- When changing a filter element a high level of cleanliness must be observed!
INTERVAL BETWEEN CHANGING ELEMENTS
We recommend fitting the filter with a clogging indicator (visual and/or electric or electronic) to monitor the filter element.
If the clogging indicator responds, it is necessary to change or to clean the filter element without delay (only W and V elements can be cleaned).
If no clogging indicator is fitted, we recommend changing the elements after specified intervals (changing the filter element depends on the design of the filter and the conditions). Higher dynamic loads across the element might necessitate shorter intervals between changes. Shorter intervals can also be expected during commissioning, repairs, oil changes etc. on the hydraulic system.
The standard clogging indicators only respond when fluid is flowing through the filter. With electrical indicators the signal can also be converted into a continuous display on the control panel. In this case the continuous display must be switched off during a cold start or after changing the element. If the clogging indicator responds during a cold start only, it is possible that the element does not need to be changed yet.
