8.1 Long Term Storage
Engine
Do not run the generator out of fuel. If the engine runs out of fuel the fuel system will
become air locked and will have to be bled before the engine will restart. Leave a small
quantity of fuel in the fuel tank. Drain any water from the water separator / filter.
Run the engine for a few minutes and drain the warm oil and fill with new oil as for a nor-
mal service.
Alternator
No special requirements other than store in a dry well ventilated place.
If the generator has been stored for a considerable period of time e.g. several years the
alternator insulation winding resistance should be checked as they can absorb moisture.
The insulation resistance must be at least 2 M
Ώ (
two mega ohms). If it is less than this
then the alternator windings can be dried out by placing the alternator in an oven at 60
-
70°C for a few hours with plenty of air movement. Generally if this procedure is required
consider replacing the alternator.
Electrical
No special requirements other than store in a dry well ventilated place.
Battery
The battery should be fully charged before storage.
Make sure the fluid level in the battery is at the normal level before storing.
Disconnect the negative then the positive connections.
It would be beneficial to trickle charge the battery periodically to maintain its condition.
General
Store in dry well ventilated place.
If the generator is to be stored long term it would be beneficial to start and run the gen-
erator under electrical load for half an hour every three months and then store as above
( but no need to change the oil each time or disconnect the battery ).
