2.3.8 Care work

Further information can be found in the operating instruc-
tions for the vehicle.
Maintenance and care of the sweeping unit
1 Check the front brush and sweeping brush for tangled
cords and straps and remove as necessary.
2 Keep the hydraulic connections clean and check for
leaks once a week.
3 Check the front brush and sweeping brush for wear and
tear and replace if necessary.
Maintenance and care of the bearings/linear unit
CAUTION
Malfunction or risk of damage
The bearing units are self-lubricating dry bearings and
must never be lubricated with any lubricant.
Brake cleaners, lubricants or other cleaners can corrode
and destroy the bearing foil. Check the bearing foil for wear
and damage and replace if necessary.
1 The existing lubrication points (grease nipples) are la-
belled.
Lubricate daily with multi-purpose grease.
2 Clean the entire linear unit with water or brine. Cleaning
with a high pressure cleaner is not a problem.
Maintenance and care of the chain
ATTENTION
Notes on lubricating the chain
When lubricating the chain, make sure that no lubricant
gets onto the rails of the linear unit. Should this happen
due to carelessness, they must be cleaned and free of
grease before initial startup.
Never use stains or acids to clean the chain.
1 Inspect the chain at least once a month. During the in-
spection, clean the chain, tension the chain drive and lu-
bricate it.
2 The chains can be cleaned with rags or brushes. Stub-
born dirt can be loosened with petroleum or benzine.
Apply new, suitable corrosion protection immediately af-
ter using grease-dissolving media.
3 The chain drive may only be tensioned by Kärcher Ser-
vice.
4 Regular lubrication extends the service life. Lubricate
the chain with relubricant VP8 FoodPlus Spay from
IWIS.
Note that the lubricant must get into the chain joint. This
means that it has to get between the protective roller
and the bushing, and also between the inner and outer
plates to the pins and bushing
5 If you notice a lack of lubrication in the form of increased
noise, stiff joints or fretting corrosion in the joints, we
recommend the following procedure.
Clean the chain with a very low viscosity oil. This flushes
fretting corrosion, old lubricant and other dirt from the
joint. When the chain has been cleaned, lubricate it with
a suitable lubricant as described above.
