Setting the cutting height
m CAUTION!
Adjust the cutting height only when the engine is
switched off and the plug boot has been pulled.
• Before you begin to mow, check to ensure that the
blade is not blunt and that none of the fasteners
are damaged.
• To prevent any imbalance, replace blunt and/or
damaged blades as a set only (if applicable). To
carry out this check, first switch off the engine and
pull the spark plug boot.
• The cutting height is centrally adjusted with the
cutting height adjustor lever (Fig.13/ Item 14). 7
different cutting heights can be selected.
• Pull the adjustor lever out and select the desired
cutting height. The lever snaps into the desired
position. (Fig. 13)

8. Operation

m CAUTION!
The engine does not come with oil in it. There-
fore, ensure that you add 0,4 liters of oil before
starting it up. Use normal, multigrade oil (SAE30).
The oil level in the engine must be checked each
time before mowing.
You will also need to fill in petrol, as this is also
not supplied upon delivery.
• In order to avoid any unintentional start-ups of the
lawn mower, it comes equipped with an engine
brake (Fig. 1/ Item 3) which must be pulled back
before the engine can be started. When the engine
control lever is released it must return to its initial
position, at which point the engine automatically
switches off.
• Press the engine brake lever (3) together and give
the starter cord (17) a vigorous pull. (Fig. 14)
Attention:
When you pull the starting rope the cutting blade
rotates even when dissolved motor brake lever.
Make sure that there are no body parts in danger
zone of cutting blade.
• Before you start mowing, you should run through
this operation several times in order to ensure that
the machine is working properly.
m WARNING
Whenever you need to perform any kind of ad-
justment and/or repair work on your lawn mower,
wait until the blade has come to a complete stop.
Always switch off the engine before carrying out
any adjustments, maintenance or repairs.
m Note!
Using the drive:
• Engine brake (3): Use the lever to stop the engine.
When you release the lever the engine and the
blade stop automatically.
• Before you start to mow, check the start/stop lever
several times to be sure that it is working properly.
Ensure that the tension cable can be smoothly op-
erated (i.e. is not catching or kinking in any way).
Caution: The blade begins to rotate as soon as the
engine is started.
Important: Before you start the engine, move the
motor brake several times to be sure that the stop
cable is properly working.
Note: The engine is factory set to a speed that is
optimal for cutting and blowing grass into the basket
and is designed to provide many years of use.
• Check the oil level.
Open the fuel tank cap and fill the petrol tank (6)
up to the lower point of the tank inlet with about 0,8
litres of petrol. Use a funnel and a measuring con-
tainer for filling. Do not overfill the tank. Use fresh,
clean unleaded fuel.
