3.13 Engine oil specification
The engine oil quality has a significant influence on the lifetime,
performance and thus also the cost-effectiveness of the engine.
The ambient temperature at the installation location or application
of the engine is crucial for the selection of the correct viscosity
class.
Too high viscosity can result in starting difficulties; too low viscosity
can endanger the lubrication effect and result in high lubrication oil
consumption. The viscosity is classified according to SAE.
Basically, use mulltigrade oils.
Depending on the lubrication oil temperature, we recommend the
following common viscosity classes.
Viscosity classes according to
ambient temperature

Concerning packing
The individual packages have been packed to match the transport
conditions that can be expected. Only environmentally friendly
materials were used for packing.
The packing has the function of protecting the individual
components against damage, corrosion, etc., until they are finally
assembled. The packaging material must therefore not be
damaged and should only be removed just before assembly takes
place.

Excess fuel device
NOTE!
The excess fuel device (Fig. 33/1) must be
pulled out for cold starting.
Fig. 31: Excess fuel device
All engines are equipped with an excess fuel device (1) to make
starting them easier.
A lever limits the injection pump control shaft's path. If the starting
excess button (1) is pulled out when starting the lever allows a
longer path for the control shaft.
As soon as the engine has reached the maximum speed permitted
by the governor the mechanical speed governor pushes the control
shaft to stop and the starting excess button returns to its starting
position.
Therefore it is important that the engine is started without load
and can reach its maximum speed. Otherwise the starting excess
button does not return to its starting position and the engine is
constantly overloaded.
NOTE!
When starting the engine when warm (operating
temperature) do not pull out the excess fuel device.
