Section 2. Operation

Prestart Checks

To insure continued satisfactory operation, the following items should be checked before each start-up.

BACKFIRE FLAME ARRESTOR: Air cleaner must be clean and properly installed to prevent unfiltered air from entering engine. See Maintenance--Air Cleaner.

BATTERY: Remove caps and check the electrolyte level of each cell (batteries with filler caps only); add distilled water if necessary. Check to make sure it is connected correctly. Battery installation and connections must meet Coast Guard Standards. Battery should be serviced by authorized personnel only. See Maintenance--Battery.

COMPARTMENT: Keep the engine room or compartment clean and dry. Check for fuel or oil leaks. Check the condition of fuel system, exhaust piping, hoses, and muffler; have any faulty components repaired before getting underway. Open hatch to air out compartment and use “ignition-protected” bilge blowers, if required, to clear fumes from area before each start-up. If fuel leaks, fumes, exhaust gases, or electrical sparks are noted, arrange for qualified personnel to make necessary repairs before operating generator set.

FUEL LEVEL: Make sure the fuel tanks are full and the

fuel system primed for operation. See Maintenance--Fuel System.

OIL LEVEL: Should be at or near Max. mark. Add oil as needed to bring level up to this range. See Maintenance Lubrication System.

COOLING: The coolant level on closed-type heat exchanger systems can be checked using the coolant recovery tank, if used. The MIN mark indicates full when cold and the MAX mark indicates full when hot. Maintain the coolant level between these marks. It is recommended that coolant level on closed systems be periodically checked by removing pressure cap. Do not solely rely on level in coolant recovery tank.

Add fresh coolant until level is just below overflow tube opening. See Maintenance--Cooling Systems.

SEAWATER PUMP PRIMING: The seawater pump must be primed before initial start-up. To prime pump, close seacock and remove the hose from water filter outlet. Fill hose and pump with clean water. Replace hose and open seacock. Check for pump operating on start-up by observing water discharge from exhaust outlet.
