9.3 As soon as the engine runs
4
► Pull the throttle trigger – the choke knob (4)
automatically returns to the run position (e).
9.3.1 At very low outside temperatures

10 Operating Instructions

10.1 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.
10.2 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".
11 Calculating Required
Quantity of Solution
11.1
Determining surface area (m
In the case of ground crops, simply multiply the
length of the field by its width.
The surface area of high-growing plants is calcu‐
lated 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.
