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.
l
Always clean tamper and engine thoroughly
before starting maintenance work.
l
For maintenance work stand the tamper on
level ground and secure it against tipping over.
l
Perform maintenance work only with the en-
gine shut down.
l
During maintenance work catch running out
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:
l
Operating errors
l
Incorrect, insufficient maintenance
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
Use only commercially available brand carburettor
fuel.
You must use unleaded standard grade gasoline.
Engine oil
Use winter grade engine oil for winter operation!
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.
For winter operation below -10 °C the oil change
intervals must be shortened.
Fig. 31
Lubrication oil with a too high viscosity index caus-
es starting difficulties. The temperature when
starting the engine is therefore of highest impor-
tance when choosing the viscosity of engine oil for
winter operation.
Oil viscosity
Since lubrication oil changes its viscosity with the
temperature, the ambient temperature at the oper-
ating location of the engine is of utmost impor-
tance when choosing the viscosity class (SAE-
class) (see diagram).
Occasional falling short of the temperature limit
(e.g. use of SAE 15W/40 down to -15 °C) may ef-
fect the cold starting ability of the engine, but will
not cause any engine damage.
