Operating instructions

Checks to be carried out
before operating the unit
Recommended oil grades
Caution!
The unit is delivered without fuel and
with oil in the engine. If the engine is
operated without adequate oil, the
engine may be seriously damaged.
This damage is excluded from the
warranty.
Before starting the engine, check

the oil level and top up if
required.
Do not overfill. The oil tank has a
capacity of approx. 1.4 litres.
Use 4-stroke oil of classification SJ
or higher.
Select the viscosity of the oil from
the following table depending on
the outside temperature:
Synthetic 5W-30
10W-30
5W-30
(ºC)
-30º -20º -10º 0º 10º 20º 30º 40º
SAE 10W-30 is recommended for
general use in the normal
temperature range. If single
viscosity oil is used, a viscosity
should be selected from the table
corresponding to the average
temperature in the area of use.
Caution!
If an inferior oil or an oil for 2-stroke
engines is used, the service life of
the engine may be damaged.

Checking the oil level
Caution!
When checking the oil, ensure that
the unit is on a level surface and that
the engine is switched off.
Always clean the area around the
dipstick before removing the
dipstick (fig. 3).
Fig. 2
Unscrew the oil filler cap (1) and

wipe the dip stick clean.
Insert the dipstick into the inlet

nozzle and tighten.
Pull out dipstick again and check

oil level. If the level is too low,
slowly pour in a little oil up to the
upper "max" mark on the dip stick.
Before starting the engine, firmly

screw in the dip stick.
Caution!
Do not pour in too much oil. If the
engine is overfilled with oil, this
may result in engine damage,
smoke formation, starting
difficulties or sooted spark plug.
Recommended fuels
!
Danger!
– Under certain conditions petrol is
extremely flammable and
explosive.
– Only refuel in a well ventilated
environment with the engine
switched off. Do not smoke near
the tank or where fuel is stored
and extinguish all ignition
sources.
30
– Do not overfill the petrol tank
(there must be no fuel in the filler
neck). After refuelling, ensure
that the tank cap is closed and
secured.
– When refuelling, ensure that you
do not spill any fuel. Spilled fuel
or petrol vapours may ignite. If
fuel has been spilled, ensure that
the area has dried before
restarting the engine.
– Avoid repeated or prolonged skin
contact and vapour inhalation.
!
Risk of engine damage!
– Do not mix fuel and oil.
– Use clean, fresh and unleaded
fuel only.
Operating manual for engine
– Use fuel with an octane number
of 87 or higher only.
– Do not use fuel of specification
E85/E15!
– Only store fuel in quantities that
can be used within 30 days.
– Do not leave any fuel in the tank
for longer than 30 days without
stabiliser – otherwise the
guarantee/warranty may be
voided.
– Ensure that no dirt, dust or water
gets into the tank.
Checking the petrol level
Caution!
Before refuelling, leave the engine
to cool down for at least two
minutes.
Follow the instructions in the unit
operating manual with regard to
checking the petrol level and filling
up.
Fig. – see unit operating manual
Before removing the fuel cap and

refuelling, clean the area around
the filler neck.
Fill the tank up to approx.

2 centimetres below the neck of
the inlet nozzle or until the fuel has
reached the maximum level
according to the indicator
(depending on model), thereby
allowing the fuel to expand.
Starting the engine
