Changing the oil
Change the engine oil every year before the start
of the season (in addition to the information in
the petrol service manual) when the engine is
warm.
• Use only engine oil (10W30).
• Place a flat oil drip tray beneath the mower.
• Open the oil filler screw (Fig. 14/Item A).
• Open the oil drainage screw (Fig. 16). Drain the
warm engine oil into a drip tray.
• Close the drain screw again when all the used
oil has been drained.
• Fill up with engine oil as far as the top mark on
the dipstick.
• Important! Do not screw in the oil dipstick to
check the oil level – only insert it as far as the
thread.
Dispose of the used oil in accordance with
applicable regulations.
7.2.4 Care and adjustment of the cables
Oil the cables at regular intervals and check that
they move easily.
7.2.4.1 Adjusting the cord for the engine
brake
If you notice a drop in the performance of the
engine brake, the cord (Fig. 17/Item A) will need
readjusting.
7.2.4.2 Drive unit cable adjustment (Fig. 18)
In the drive position of the clutch lever (Fig. 13),
the clutch lever (Fig. 1/Item 1) should be pulled
up to the top push bar. If the cable is too taut,
it must be set to a longer length. To do this,
undo the lock nut (Fig. 18/Item A) opposite the
main cable (Fig. 18/Item B), extend the screw
connection and then tighten the lock nut again.
If the power of the drive unit starts to fall, the
clutch tension must be increased using the
54
cable. To do this, the screw connection must be
reduced (using the method described above). Set
the clutch lever (Fig. 1/Item 1) so that it can just
touch the top push bar.
7.2.5 Maintenance of the air filter (Fig. 19/20)
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.
7.2.6 Maintenance of the spark plug (Fig. 22)
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. 21) with a twist.
• Remove the spark plug with the supplied spark
plug wrench.
• Assemble in reverse order.
7.2.7 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.
