Water for coolant should be clean and free from any corrosive chemicals such
as chlorides, sulphates and acids. It should be kept slightly alkaline with a PH
value in the range 8.5 to 10.5. Antifreeze must be added to the coolant where
is any possibility of freezing to protect the engine form damage due to coolant
freezing. A 50% antifreeze / 50% water mixture is recommended.
6.3 Fuel choice
It is very important that the fuel oil purchased for use in any engine be as clean
and water-free as possible. Dirt in fuel, the fuel can clog injector outlets and
ruin the finely machined precision parts in the fuel injection system. Water in
the fuel will accelerate corrosion of these parts. The fuel temperature is a
critical factor for appropriate working conditions of the engine.
6.4 Daily check
Inspect the generator set daily or after every 8 hours of operation. Check the
mechanical, exhaust, fuel and DC electrical systems as described below.
6.4.1 New machine
1) Run the generator set at least 60-100% of continuous load for the first 100
hours.
2) Change engine oil and replace oil filter after the first 50 hours.
6.4.2 Mechanical system
Inspect any signs of mechanical damage. Start the generator set and listen for
any unusual noises, which may indicate mechanical problems. Repair them
immediately.
Inspect the mounting fasteners to make sure the generator set is secure in its
compartment.
Check the generator set air inlet and outlet areas, make sure that they are not
blocked with debris.
Clean the machine whenever dust and dirt begin to accumulate. Usually
remove dust and dirt with a damp cloth.
