Maintenance

5.1 General

When performing maintenance work ensure
strict compliance with the respective safety in-
structions and particularly the safety regula-
tions mentioned in chapter 2 of these
operating and maintenance instructions.
Thorough maintenance of the tamper guarantees
far longer safe functioning of the machine and pro-
longs the lifetime of important components. The
effort needed for this work is only little compared
with the problems that may arise when not observ-
ing this rule.
Always clean tamper and engine thoroughly
G
before starting maintenance work.
For maintenance work stand the tamper on
G
level ground and secure it against tipping over.
Perform maintenance work only with the en-
G
gine shut down.
During maintenance work catch running out
G
oils and fuel environmentally and do not let
such substances seep into the ground or into
the sewage system. Dispose of oils and fuel
environmentally and avoid contact with skin
and eyes.
Frequent causes of faults:
Operating errors
G
Incorrect, insufficient maintenance
G
If you cannot locate the cause of a fault or rectify it
yourself by following the trouble shooting chart,
you should contact the service departments at our
branch offices or dealers.

5.2 Fuels and lubricants

Fuel
Quality
The engine has been approved for operation with
unleaded gasoline with a octane number of 86 or
higher (research octane number of 91).
Use only commercially available brand fuel.
Engine oil
The oil is an essential factor for the performance
and liftime of the engine.
Use engine oil for four-stroke engines which meets
or even exceeds the requirements for API-service
class SJ or higher (or equivalent).
Fig. 29
In order to assure perfect cold starting it is import
to chose the viscosity (SAE-class) of the engine oil
according to the ambient temperature.
SAE 10W-30 is recommended for general use.
Other viscosities from the table can be used as
long as the average temperatures in your area
stay within the specfied limits.
Lubrication oil with a too high viscosity index caus-
es starting difficulties, the temperature when start-
ing the engine is therefore of highest importance
when choosing the viscosity of engine oil for winter
operation.
Use winter grade engine oil for winter operation!
For winter operation below -10 °C the oil change
intervals must be shortened.
