• Personal protective equipment must be used to prevent injury from tools or components.
• The maintenance area must be kept clean and tidy. Objects lying around can be a tripping hazard
• If there is any uncertainty, consult the supervisor or the manufacturer.
The maintenance plan provides for the following activities:
For cleaning the filter cartridge, proceed as follows, depending on the installation:
1. paper filter cartridge
• Blow through with compressed air from the inside to the outside. Make sure that there is sufficient distance,
as too hard an air flow can damage the filter material.
2. polyester filter cartridge
• First free the filter from coarse dirt by lightly tapping it out.
• Rinse the filter carefully with a not too hard water jet from the inside to the outside. For stubborn dirt, it is
recommended to soak the filter in a mild soap-based cleaning bath.
• Shake the excess water out of the filter and let it dry out completely in the air. When drying with
compressed air, make sure there is sufficient distance, as too hard an air flow can damage the filter material.
ATTENTION
• Always allow polyester filters to dry after cleaning with water. - Danger of adhesion or mould!
• Water in the pump leads to contamination of the oil, and there is also a risk of corrosion!
NOTE
External filters are available in many sizes and designs. For further information, please contact BECKER
Service
If the filter's function is restricted (clogged, oily, greasy or damaged) even after the cleaning process, it must be
replaced. Replacement should take place after one year at the latest
For information on oil types and filling quantities, see chapter 9.3
Clean the intake filter (optional)
Depending on the degree of contamination of the intake air, the pre-
filter becomes clogged. It must be cleaned by compressed air at the
intervals shown opposite, but at least every 200 hours.
If the filter's function is restricted (stuck or damaged) even after the
cleaning process, it must be replaced.
Only use original spare parts from the manufacturer.
Check oil level
The oil level can be read off the oil sight glass after an appropriate
waiting time, in a shut-down state and ventilation to atmospheric
pressure.
The oil lubricates the rotary vane in the compressor chamber. The
thermal energy released in the process causes the oil to evaporate into
oil mist. Despite the use of an air-oil separator (LEE), small amounts of oil
mist are pumped out of the pump. Therefore, the oil level must be
checked regularly and adjusted if necessary.
