English Operating manual for engine
Use only 4-stroke oil belonging to classification SF/SG/SH/SJ or higher. Select the viscosity of the oil from the following table depending on the outside temperature:
a) Single viscosity b) Multiple viscosity
SAE 10W-30 is recommended for general use in the normal tempera­ture range. If oil with an individual viscosity is used, a viscosity should be selected from the table for the average temperature in the application area.

Note
– Some models have no throttle
and the speed is adjusted auto­matically. The engine always runs at optimum speed.
– Even if the engine is warm, it may
be necessary to actuate the choke.
– Some models have no choke.
The engine is automatically set to the particular starting process.
– Leave the engine to warm up for
several minutes before working with the unit.
Move the throttle (1) – if fitted – on
the engine or steering handle (for units with throttle remote control – depending on model) to position
.
Actuate the choke
(if the engine is cold): – Move choke (2) to position
/ON.
Stand behind the unit.Pull gently on the starter handle
until it begins to resist. Then pull quickly and forcefully to overcome the compression, prevent recoil and start the engine. If required, repeat.

To maintain a constantly high power, it is essential to inspect and re-adjust the engine on a regular basis. Regular maintenance ensures a long service life.
The required maintenance intervals and the type of maintenance work to be carried out are indicated in the following table. The intervals according to operating hours or other times/dates should be observed according to which occurs first. If the engine is operated under difficult conditions, more frequent mainte­nance is required.
At the end of the season have the unit inspected and serviced by a specialist company.

Fill the oil tank with the recom-
mended oil and check the oil level.
Re-attach the oil filler cap.
Important
Dispose of waste oil according to the currently valid regulations for the protection of the environment. It is recommended to take the waste oil in a leakproof container to a waste oil collection centre. Do not dispose of with residual waste or pour onto the ground and leave to seep away.
Servicing the air filter
A dirty air filter restricts the air flow to the carburettor. To prevent the carburettor from malfunctioning, the air filter should be serviced regularly. In an extremely dusty environment more frequent maintenance may be required.

To ensure that the engine runs correctly, the gap between the electrodes on the spark plug must be set correctly and free of contaminants.
Figs. 6 and 7
Remove the spark plug
terminal (1) and unscrew the spark plug (2) with a spark-plug wrench.
Visually check the spark plug.
Replace the spark plug if it is clearly worn or the insulator is damaged.
Clean the spark plug with a wire
brush if it is to be used again.
Measure the gap between the
electrodes with a feeler gauge. If required, re-adjust the gap by slightly bending the side elec­trode. The gap between the electrodes should be
0.60–0.80 mm (Fig. 7).
Check that the sealing ring on the
spark plug is in good condition, then screw in the spark plug by hand to prevent damage to the thread.
When the spark plug is hand-tight,
tighten with the spark-plug wrench.

Cleaning the engine
If the engine has already been running, leave it to cool down for at least one hour before cleaning. Regularly remove accumulated dirt from the engine. Clean the finger guard and the area around the exhaust. Use a brush or compressed air.

Storage
Engines which are stored for longer than 30 days should have an empty fuel tank in order to prevent the formation of residue in the fuel system, especially on important parts of the carburettor.
If storage is from 30 to maximum 90 days, a stabiliser can be added to the fuel. Contact your dealer or the customer service centre.
Leave the engine running until
the tank runs out of fuel and the engine stops.
Change the oil.
See “Changing the oil”.
Remove the spark plug and pour
approx. 15 ml of engine oil into the cylinder. Re-install the spark plug and slowly pull the starter cable to distribute the oil.
Remove dirt around the engine,
under the finger guard and under, around and behind the exhaust. Apply a light film of oil to areas which could rust.
Store in a clean, dry and well
ventilated area away from units which operate with a flame or a warning lamp, e.g. heating equipment, boilers or tumble­dryers. Areas should also be avoided in which a spark­generating electric motor is situated or in which electric tools are used.
If possible, storage areas with
a high air humidity should not be selected either, as this promotes the formation of rust and corro­sion.
Store the unit on a flat surface.
If the unit is on an incline, fuel or oil may run out.
Procedure following prolonged storage
Check the engine as described in
the section ”Checking the engine
before start-up”.
If the fuel was drained prior to
storage of the unit, fill up the tank
with fresh petrol. If a petrol can is
used for refuelling, ensure that it
contains fresh petrol.
If the cylinder was oiled during
storage, the engine generates
a little smoke when it is started.
This is normal.
Warranty
The warranty regulations issued by our company or the importer are valid in all countries. We shall repair any faults on your unit free of charge in accordance with the warranty, provided the fault was due to defective materials or manufac­turing. If claiming under the warranty, please contact your seller or your nearest branch.
