Changing the engine oil
Caution! Danger to the environment from engine oil
After carrying out an oil change, ensure that the waste oil is passed to an
appropriate collection point or official disposal company.
Caution,
Run the engine until it reaches its normal operating temperature.
Make sure the sweeper is standing on a level surface.
Open the unit cover.
Place a drip pan under the engine.
Hold the end of the drain tube over the drip pan and let the old oil run out.
Close off the end of the drain tube again.
Pour engine oil into the filler hole.
Capacity = 1.1 litres
Check the oil level with the dipstick – see "Checking the oil level" .
Wipe up any oil spillage and dispose of the waste oil appropriately.
Cleaning or replacing the air cleaner
Do not run the engine without an air cleaner otherwise this will
lead to increased wear on the engine
The air cleaner must be washed out more frequently if the engine is run in
particularly dusty environment.
Do not wash the air cleaner in petrol or a cleaning solvent with a
low flash point.
Paper insert 1: Replace the insert if it is very dirty. Otherwise, blow com-
pressed air through the insert from the inside to out or knock it against a
hard surface. Do not brush it off, otherwise the dirt will be compacted
between the fibres.

Foam insert
: Wash out the insert in a solution of washing-up liquid and
warm water. Rinse it out and allow it to dry out thoroughly. Immerse the
clean insert in engine oil and squeeze out the excess fluid. If too much oil
is left in the insert, smoke will be given off by the engine when it is next
started.
Check gas installation
Check the gas hose for damage daily and the threaded joints in the piping
for firm seating.
Half-yearly or every 100 operating hours check the piping system for
leakage.
Annually check the gas installation, clean the evaporator/pressure regula-
tor and replace the seals.
Check that the CO content in the exhaust gas is < 0.5 % when idling and
at full load.
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.
