Danger: when cleaning battery, do not smoke or carry out fire-related works
nearby because the hydrogen generated during electrolysis of battery may cause
an explosion.
7. Check restriction indicator of air filter and clean the filter if restriction display
appears.
8. Check if air switch of the Gen-set is off.
II. Preparations before commissioning
1. Refilling of coolant
1.1 Coolant selection
Generally, anti-freeze is used as coolant of the Gen-set. Anti-freeze is one kind of
coolant containing special additives.
Anti-freeze refilled in engine has following functions:
1) Ensure that engine operates in a normal temperature range;
2) Prevent corrosion of parts in cooling system;
3) Prevent water scale and avoid efficiency reduction of radiator;
4) Effectively prevent “boiling” of water tank in summer;
5) When stopping the Gen-set while ambient temperature in winter is low, be sure to
prevent radiator and cylinder block or head of engine from being damaged by
expansion of frozen coolant. The anti-freeze to be selected will be different when
ambient temperature is different. For details of coolant grade, please see Table 7-1.
