TP-5695 12/93 Operation 2-1
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.
