12.6 Maintenance of the air filter (Fig. 20/21)
A soiled air filter will reduce the performance of the
engine because it will prevent enough air getting to
the carburetor. It is therefore imperative that regular
checks are made. The air filter should be checked
every 25 hours and cleaned if required. If the air is
very dusty the air filter should be checked more
regularly.
Important: Never clean the air filter with petrol or
inflammable cleaning agents. Clean the air filter with
compressed air or simply by knocking out any
soiling.

12.7 Maintenance of the spark plug

Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean it with a
copper wire brush. Thereafter service the spark
plug after every 50 hours of operation.
Pull off the spark plug boot (Fig. 22) with a twist.
Remove the spark plug with the supplied spark
plug wrench.
Assemble in reverse order.
12.8 Tensioning the V-belt for the
travel drive (Fig. 24).
Check the tension of the V-belt for the travel drive at
regular intervals and re-tension it if required. To do
so, set the mower to the top cutting height. Slacken
the lock nut (Fig. 24/Item A) and adjust the tension of
the V-belt using the setting screw (Fig. 24/Item B).
Retighten the lock nut once you have completed the
readjustment work.
Tip: Adjust the setting screw by just 1 - 2 turns and
then give the mower a test run before adjusting by
the same amount again, if required, in order to avoid
the risk of tightening the V-belt by too much.
12.9 Repairs
After any repair or maintenance work, check that all
safety-related parts are in place and in proper
working order.
All parts which may cause injury must be kept where
they are inaccessible to children or others.
Important: In accordance with product liability
legislation we are not liable for any damages caused
by improper repairs or the use of spare parts that are
not original spare parts or parts approved by us. In
addition, we are also not liable for any damages
arising from improper repairs. Such work should be
performed by a customer services workshop or
authorized specialist. The same applies to accessory
parts.

13. Preparing the mower for long-term
storage
Caution: Do not empty the petrol tank in enclosed
areas, near fire or when smoking. Petrol fumes can
cause explosions and fire.
1. Empty the petrol tank with a petrol suction pump.
2. Start the engine and let it run until any remaining
petrol has been used up.
3. Change the oil at the end of every season. To do
so, remove the used engine oil from a warm
engine and refill with fresh oil.
4. Remove the spark plug from the cylinder head.
Fill the cylinder with approx. 20 ml of oil from an
oil can. Slowly pull back the starter handle, which
will bathe the cylinder wall with oil. Screw the
spark plug back in.
5. Clean the cooling fins of the cylinder and the
housing.
6. Be sure to clean the entire machine to protect
the paint.
7. Store the machine in a well-ventilated place.
14. Preparing the mower for
transportation
1. Empty the petrol tank (see item 13/1).
2. Always let the engine run until it has used up the
remainder of petrol in the tank.
3. Empty the engine oil from the warm engine.
4. Remove the spark plug boot from the spark plug.
5. Clean the cooling fins of the cylinder and the
housing.
6. Remove the start tension cable from the hook
(Fig. 7). Slacken the wing nuts and fold down the
upper push bar (Fig. 4/5).
7. Wedge a few layers of corrugated cardboard
between the upper and lower push bars and the
engine in order to prevent any chafing.
