Operation
In principle, all engine oils of the same specification can be
mixed. However, mixing of engine oils should be avoided be-
cause the worst properties of any of the components in the
mixture are always dominant, affecting the result.
The following lubricating oils are permissible for the engine in
this operating manual:
The ambient temperature at the installation site or in the ap-
plication area of the engine is decisive for choosing the right
viscosity class. Too high a viscosity can lead to starting diffi-
culties, too low a viscosity can endanger the lubrication effect
and cause a high lubricating oil consumption.
Depending on the ambient temperature, the following com-
mon viscosity classes are recommended:
Check the engine oil level by pulling out the yellow oil dipstick
handle (A), located adjacent to the fuel filter can. Unscrew the
oil fill cap (B) and add engine oil (API CJ-4), if necessary.

Check the battery, the case and the battery terminals.
Lead-acid batteries produce flammable and potentially ex-
plosive gases. To avoid death or serious injury when check-
ing, testing, or charging batteries:
• DO NOT use smoking materials near batteries.
• Keep arcs, sparks, and open flames away from batteries.
• Provide ventilation for flammable vapors.
• Wear proper personal protective equipment, including
safety glasses.
