Stopping the Engine
N Move the setting lever in the
direction of 0 – the engine stops –
the setting lever springs back to the
on position.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This helps protect engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
engine to cool down. Keep the machine
in a dry place, well away from sources of
ignition, until you need it again. For
longer out-of-service periods – see
"Storing the Machine".
Determining surface area (m
2
)
In the case of ground crops, simply
multiply the length of the field by its
width.
The surface area of high-growing plants
is calculated approximately by
measuring the length of the rows and the
average height of the foliage. The result
is multiplied by the number of rows and
then by two if both sides have to be
treated.
The surface area in hectares is obtained
by dividing the number of square meters
by 10,000.
Example:
A field 120 meters long and 30 meters
wide has to be treated with a pesticide.
Area:
120 m x 30 m = 3,600 m

3,600 / 10,000 = 0.36 ha
Determining quantity of active ingredient
Refer to the instructions supplied with
the active ingredient to determine:
– Required quantity of active
ingredient for 1 hectare (ha).
– Concentration of active ingredient
(mix ratio).
