have the inspection done by your Kärcher Customer Ser-
vice.

correctly
– check that the handbrake functions

dust, shake them out.

Risk of injury
Before you work under the waste hopper in its swung-up
position, you must first secure the hopper against dropping
unintentionally by using the swing-out safety bar.
– Remove ignition key
– Pull out battery plug connection
– Open cover
Tip seat forwards. Pull cover up by the handle grip
designed for the purpose.
Checking the hydraulic system
– Carry out a visual inspection. If there is any loss of fluid
from the hydraulic unit, cylinder or hoses, call Kärcher
Customer Service.
Replacing the sealing skirts
The sealing skirts fulfil an important function. They retain the
partial vacuum in the area round the main brush roller which
is essential so that the sweeper can function properly. They
ensure that sweeping can take place without clouds of dust
being raised.
If the sealing skirts are damaged or worn out, they must be
replaced immediately.
– Park the sweeper and switch off the engine.
– Remove the retaining screws and detach the sealing
skirts.
– Fit new skirts, and align them as follows:
The side skirts should be adjusted so that they clear the
ground by 1–3 mm. Adjust the rear skirt so that it clears
the ground by 1-5 mm.
– The front skirt cannot be adjusted. Replace the skirt as
soon as you see signs of excessive wear.
– Tighten the retaining screws.
Replacing the side brush
– Park the sweeper, switch it off and make it secure.
– Raise the side brush.
– Remove the three hex-socket bolts (SW 5).
– Detach the side brush.
– Push the new side brush onto the drive pin.
– Tighten the bolts again.
