Maintenance
IMPORTANT INFORMATION:
Avoid using a high pressure washer or a steam cleaner.
Lubricate the machine if necessary after cleaning.
Carry out extra lubrication when the bearings have
been exposed to a degreaser or a water jet. There is a
major risk of water penetrating into bearings and
electrical connections. Corrosion attack, which will
lead to running problems. Cleaning additives generally
aggravate the damage.
Check and clean if dirt collects in the area for the
circuit card and on the circuit card. Clean using a dry
method, i.e. with a vacuum cleaner or compressed air.
Do not blow directly on the circuit card. Do not rinse
with water. There is a risk of damaging the circuit card.
