7. Maintenance
7.2.2
Rotary compressor/compressor and
vacuum pump
The machine must be cleaned weekly.
When washing or spraying with high
pressure water jets there is a danger of
water penetration which can cause
foaming, and thus lead to a machine
failure.
Carefully clean the oil level monitoring window.
After wet cleaning the machine should be run warm
for a few minutes to prevent the rotor vanes from
sticking.
7.2.3
Vacuum filter
Clean the filter, depending on the degree of dirt, every
day, but at least once per week.
When the ventilation valve activates, the
vacuum filter should always be cleaned.
The filter element consists of high grade steel netting
or a fine filter cartridge.
To open the filter
Loosen or unscrew the cone or cross clamps (7.1/2,
3). In the SFA type, turn the cover (7.1/1) anti-
clockwise by about 15° out of the stud bolts, and
pull the cover out of the housing. In the SFD type,
the cover can simply be taken off.
To clean the filter
Rinse the filter housing with petrol or cold
degreasing solvent.
Filter elements of high grade steel netting can be
rinsed with petrol or cold de-greasing solvent.
Filter elements with a fine filter cartridge can be
blown through from the inside to the outside with a
steam jet. Check the fine filter cartridge for damage.
Damaged cartridges must be replaced.
When cleaning the filter housing, under no
circumstances must dirt, cleaning pad
remnants or liquid be allowed to get into the
compressor/vacuum pump. This can cause
the vanes to fracture.

Assembly of the filter
Insert the filter cartridge.
Place the seal or sealing ring in the cover (7.1/1).
Press the washers to the outside against the cone
or cross clamps (7.1/2,3).
Press the cover (7.1/1) into the housing (in the SFA
type, twist the cover clockwise into the stud bolts).
Tighten the cover with the cone clamps or cross
clamps (7.1/2,3).
7.2.4
V belts and V belt tension
Drive protection devices must only be
removed when the machine is at a standstill
and the vehicle engine is switched off.
V belts and the V belt tension must be checked every
week and, if necessary, tightened or replaced; cf.
Damaged V belts must only be replaced by a complete
set of belts of the appropriate assorted lengths.
7.2.5
Cleaning oil reservoir
The oil reservoir must be cleaned every 3 months.
Drain the lubricating oil when the machine is at a
standstill. Rinse the oil reservoir with rinsing oil.
The oil reservoir must not be rinsed with
solvent or cold cleaning liquid.
Before switching on the machine again, do not forget
the preliminary lubrication! See

operation”
