Preparation
Prior to all maintenance and cleaning
work:
1. Let the device cool down for at least
20 minutes.
2. Pull off the spark plug connector.
3. Close the fuel valve and the tank
ventilation.
4. For work on the bottom of the device, tilt
the device to the silencer side.
Cleaning the device
After each use, you should clean the device
thoroughly, especially the bottom side and
the blade.
Stuck grass or dirt affect the grass discharge
and the cutting quality. For a sufficient engine
cooling, keep the engine cover, ventilation
grid, and the engine clean.
Fire hazard! Pay special attention so that
components at the silencer are clean.
For cleaning use a hand brush. Remove
stubborn soiling with a wooden or plastic
spatula. Clean the outer housing parts with a
cloth.
Do not rinse off the device with a water jet or
high pressure cleaner! Do not use aggressive
cleaning agents.
General inspection
To ensure a safe working condition of the
device, check all nuts, bolts, screws,
connections of fuel lines, air filters, etc.
regularly for firm seating. Check the ignition
wire and the spark plug connector for
damage.
Immediately replace damaged or worn parts,
especially covers, impact protection, silencer,
or fuel tank (authorised service centre).
Maintaining the engine
Danger!
If the speed of rotation is set too
high, objects can be ejected. The
engine can be damaged and noise
pollution increases.
Do not change the basic setting of
the carburetor or the speed
control.
To ensure a long service life of the engine,
sufficient engine cooling is required.
Keep the
- engine cover (ventilation grid),
- silencer (protective grid) and
- cooling fins of the engine
clean at all times.
Checking the spark plug
Danger!
The ignition system generates an
electromagnetic field.
Wearers of pacemakers must not
work on live parts.
Soil spark plugs reduce the engine output.
Clean the electrode of the spark plug with a
brass wire brush. Check the electrode gap
(see “Technical data”). Make sure that the
insulator around the electrode is not
damaged. Never use a damaged spark plug.
Tighten the spark plug with the torque
indicated in the technical data.
