MAINTENANCE AND  ADJUSTMENTS 
Introduction 
This section contains a scheduled preventive maintenance program and several adjustment procedures the 
owner/operator can perform without the benefit 
of 
sophisticated and 
e".-pensive 
tools and instruments. 
Preventive 
Maintenance 
Perform the preventive maintenance in accordance with the schedules listed in the following paragraphs. 
Adherence to these schedules will  ensure the equipment is maintained in the best possible condition and 
that it will  perform  to  expectations.  Those  items  marked by  an asterisk  ( 
* ) are recommended to be 
performed by 
an 
authorized dealer or distributor. 
Daily (before 
each 
use) 
1. 
Check the oil sump level.  Maintain the oil level at or near the upper level mark on the dipstick. 
2. 
Check the coolant level in the plastic recovery tank.  Maintain this level 
at 
or above the level  marked 
ADD.  Periodically, check the coolant  level  in the manifold.  It should be  filled  to the top 
of 
the filler 
neck. 
3. 
Visually  inspect the unit;  check for  loose  belts,  chafed or broken  wires,  loose  brackets and fittings, 
damaged hoses, loose clamps and other equipment not properly secured. 
4. 
Check the fuel supply.  Fill tank(s) with a good grade 
of 
No. 
2 diesel fuel, 
if 
required. 
5. 
Check  the  primary  filter/water  separator.  Drain and  service  as  required.  (A primary filter/water 
separator is  optional, but strongly  recommended as damage to fuel equipment on the engine from  fuel 
contaminants is not warrantable.) 
6.  Check the generator's  gauges  or lights for proper oil pressure,  operating temperature, 
and 
starting 
battery charging voltage once the engine is operating. 
7. 
Check the generator's output meters (when installed) for proper AC voltage and output frequency. 
Monthly 
Check the condition 
of 
the  zinc anode  in the  heat  exchanger's  sea  water circuit.  Clean 
or 
replace  the 
anode, as required.  Keep the area inside the heat exchanger clean 
of 
zinc anode debris. 
Servicing 
After 
Initial 
50 
Hours 
of 
Olleration 
1. 
Change the engine's lubrication oil and oil filter. 
2. 
Replace  the  fuel filter  element  in  the  engine-mounted secondary fuel  filter.  Change  the fuel filter 
element  and  clean the filter/water  sedimentor, 
if 
a  separator has been  installed, and 
if 
the  model type 
pennits cleaning.
