5.1
Stop the engine and switch off
NOTE For further information: Refer to the
lawn tractor's operating instructions.
When starting and stopping the engine, be sure
to disengage all lawn tractor traction equipment,
the drive to work tools (such as the power mow-
er).
Only start the engine in a horizontal position, do
not use the engine in inclined positions with a
gradient of more than 15°.
■
Cold start problems may occur if the outside
temperature is low.
■
Warm start problems may occur if the outside
temperature is low due to evaporation in the
carburettor chamber or pump.
■
In either case the grade of oil must be adapt-
ed to the operating temperatures.
■
The maximum power of an internal combus-
tion engine progressively decreases with the
increase in altitude above sea level. Exces-
sive engine load and heavy work must there-
fore be avoided with increasing altitude.
