The oil mist lubricator, see section 5.1.2 Oil mist lubricator, must be checked at regular intervals, the
condensation must be removed and the EFA special oil replenished.
7.3.2 Sharpening the blades
Danger! Cutting hazard
Incorrectly sharpened blades result in
production losses or a considerable
hazard for the user.
We have established a sharpening service for you in our Service department.
Please contact the nearest authorised service centre or our head office in this case.
However, if used correctly, it is usually not necessary to resharpen the blades.
If necessary, the blades can also be resharpened with commercially available sharpening equipment if only a
small amount of material has been worn away.
Do not use force, as parts could be damaged!
Only use genuine EFA spare parts!
7.3.3 Repair by customer service
Danger! Disconnect the device from the
plant network prior to performing
any repair work!

GmbH is at your disposal for repairs.
In the event of faults that cannot be clearly localised, the machine should always be returned to Schmid &
Wezel GmbH for repair.
Do not repair defective devices on site (in the immediate vicinity of foodstuffs)!
