Oil level check
- Useaclean,lint-freecloth
The oil level must be measured with oil warm from operation (approx. 80 C
[176 F]) and with the motor at a standstill. Measurements with cold oil are not
meaningful.Thedesiredmotortemperatureisachievedafteradrivingtimeof
approx.10minutesat4000-4500U/min[RPM].
Measurement with a motor warm from operation is necessary, because
the oilvolume changesdepending on thetemperature. To avoid mistaken
