Preparation and maintenance in winter time
Maintenance in winter time is considered to be the period when the temperature of the ambient air is
fixed below +5 С. The low temperature of the ambient air hampers the engine start, negatively
influences the operation of all its systems. To prepare the generator and provide its further no-failure
operation it is necessary to make the following steps:
- Use up all the old fuel completely, discharge the remaining one.
- Clean the filter of the fuel valve.
- Check the air filter. Change it if necessary.
- Substitute the engine oil for the oil corresponding to the season.
- Fill the fuel tank with the fuel to avoid ingress of water and its further freezing in the fuel
tank and the carburetor.
The generator is to be kept in a place at the temperature from +5 С and above in winter time. If the
engine stops for more than 15 minutes during the operation at negative temperatures it is necessary
to place the set into a warm place to prevent the condensate freezing in the breather pipe and the
throttle before its start. It may cause the pressure boost in the crankcase housing and the gaskets
break down. The monitoring of the set operation is to be carried out oftener than under usual
operating conditions as they are considered to be rough.
The maintenance interval frequency and the operations to be carried out are outlined in the
maintenance programme.
However, it should be added that it is the environment in which the generating set is operating
which determines this programme. Accordingly, if the set is used in extreme conditions, shorter
intervals between maintenance procedures should be adopted.
These maintenance schedules apply only to generating sets running on fuel and oil, that
conform to the specifications given in this booklet.
