ATTENTION
Product damage!
Using the product without or with too little engine and
gear oil can result in engine damage.
– Fill with fuel and oil before commissioning. The
product is supplied without engine and gearbox oil.
– Only use SAE 10W-30 or SAE 10W-40 engine oil.
ATTENTION
Environmental damage!
Spilled oil can pollute the environment permanently.
The liquid is highly toxic and can quickly lead to water
pollution.
– Fill/empty oil only on level, paved surfaces.
– Use a filling nozzle or funnel.
– Collect drained oil in a suitable container.
– Wipe up spilled oil carefully immediately and dis-
pose of the cloth according to local regulations.
– Dispose of oil as per local regulations.
1. Turn the oil dipstick (13) anticlockwise to unscrew it
and wipe it with a clean, lint-free cloth.
2. Reinsert the oil dipstick (13) and check the oil level
without screwing the oil dipstick (13) tight again.
3. Pull the oil dipstick (13) out and read the oil level in
the horizontal position. The oil level must be within the
marking on the oil dipstick (13).
4. Then screw the oil dipstick (13) in again.
13.2.3 Oil change
The engine oil change should be completed annually be-
fore the start of the season while the engine is at operat-
ing temperature and shut off.
Only use engine oil (SAE 10W-30/SAE 10W-40).
1. Unscrew the oil dipstick (13) by turning it anticlock-
wise.
2. Suck out the engine oil through the filler neck using an
oil pump (with hose).
3. Fill up with fresh engine oil and check the oil level
(see 10.1).
13.2.4 Drain fuel with a fuel extraction pump
(Fig. 8)
1. Hold a collection bucket under the hose on the fuel
extraction pump.
2. Unscrew and remove the fuel filler cap (4a).
3. Push the hose of the fuel extraction pump into the fuel
tank (4) and drain out the fuel tank completely using
the fuel extraction pump.
4. Retighten the fuel filler cap (4a).
5. To ensure that no fuel remains in the carburettor, the
remaining fuel must be drained out of the carburettor.
To do this, place a collection bucket under the carbu-
rettor and open the carburettor screw (18) with the aid
of an open-end wrench AF10.
13.2.5
DANGER
Risk of fire and explosion!
If not cleaned correctly, fuel may ignite and even ex-
plode. This can lead to severe burns or death.
– Only clean the air filter by knocking it out.
– Never clean the air filter with petrol or flammable
solvents.
ATTENTION
Risk of damage!
Operating the engine without a filter element or with a
damaged filter element can cause engine damage.
– Never run the engine without the air filter element or
with a damaged filter element. This would allow dirt
into the engine, which would result in severe dam-
age to the engine.
Fouled air filters (5a) diminish the engine output due to re-
duced air supply to the carburettor. Regular inspection is
therefore essential.
The air filter (5a) should be checked every 25 operating
hours and cleaned as required. The air filter (5a) must be
checked more often in case of very dusty air.
1. Take off the air filter cover (5) and remove the air filter
(5a).
2. Clean the air filter (5a) only by knocking it out.
3. Replace a defective air filter (5a) with a new one.
4. Put the air filter (5a) back in place and replace the air
filter cover (5).
13.2.6
Check the spark plug (8a) for contamination for the first
time after 10 operating hours and clean it with a copper
wire brush if necessary. Then maintain the spark plug
(8a) every 50 operating hours.
1. Pull off the spark plug connector (8) with a twisting
motion.
2. Remove the spark plug (8a) with a spark plug wrench.
3. Use a feeler gauge to set the gap to 0.75
mm( 0.030"). Refit the spark plug (8a) and take care
not to overtighten it.
13.2.7
The engine is equipped with a mechanical brake which
has to be checked regularly. When releasing the engine
brake lever (1b), the blade (17) must come to a standstill
within 7 seconds.
A running blade (17) produces clearly perceptible wind
noises. The running of the blade (17) is signalled by the
wind noise generated and can thus be controlled.
NOTE
If you notice that the blade stopping device is not work-
ing correctly, please contact the customer service or a
specialist workshop.
