5 START-UP
NOTE Inspect the appliance for damage
every day before starting work, if it is dropped or
is subjected to other impacts. Have any damage
repaired before putting the appliance into opera-
tion.
5.1 Mixing and pouring in the petrol/oil
mixture
IMPORTANT! Danger of engine damage.
Pure petrol will result in damage and complete
failure of the engine. Guarantee claims against
the manufacturer are excluded in this case.
■
Always operate the engine using the speci-
fied petrol/oil mixture ratio.
Producing the petrol/oil mixture
The 2-stroke engine requires:
■
Lead-free, fresh petrol with an octane rating
of at least 90. Petrol stored for longer than 2
months will lead to deposits and malfunctions
of the engine.
■
High-quality synthetic oil for 2-stroke engines
Prepare a petrol/oil mixture in a ratio of 50:1 us-
ing these two constituents:
Mixing ratio
50 parts petrol: 1
part 2-stroke oil
1. Pour the petrol and 2-stroke oil into a fuel
mixing bottle (quantities, see table, depend-
ing on the size of the fuel mixing bottle).
2. Close the fuel mixing bottle and shake vigor-
ously several times so that the petrol and oil
can mix thoroughly.

Pouring in the petrol/oil mixture (14)
1. Place the appliance on a level, horizontal sur-
face. The cap (14/1) of the fuel tank must be
facing upwards.
2. Wipe the fuel tank cap (14/1), the fuel tank
(14/2) and the surrounding appliance parts
clean so that no dirt can get into the fuel tank
when the petrol/oil mixture is poured in.
3. Open the fuel tank cap slowly so the pres-
surised petrol/air mixture can slowly escape
from the fuel tank into the atmosphere. Leave
the cap hanging on the fuel tank.
4. Insert a funnel (14/3) into the filler neck (14/4)
of the fuel tank.
5. Pour the prepared petrol/oil mixture from the
fuel mixing bottle (14/5) into the fuel tank up
to the lower edge of the filler neck, but not
higher.
6. Remove the funnel and screw on the cap fin-
ger-tight.
7. Wipe any spilled petrol/oil mixture off the ap-
pliance and the surface.
