REGULAR MAINTENANCE
CHECK DAILY:

Take care the oil level is never
below the mark. Do not add oil
when the level is still above
the mark

CHECK DAILY:
•
Level cooling liquid
•
Hoses for loose connections or deterioration.
AFTER FIRST 50 HOURS:
•
Change oil and replace the oil filter.
Have the engine run until it is on temperature and
stop it. Replace the oil filter. Drain oil by the sump
pump into a suitable retainer and fill up with fresh
oil. Start the engine again and have it run for 5
minutes. Stop the engine again and pause for a
few minutes to let the oil gather in the crankcase.
Check the level again and add oil when
necessary.
•
Check and tighten nuts, bolts, and unions, paying
particular attention to the fuel system.
•
Observe the exhaust at the normal full load. The
exhaust must be free from soot. Do not allow the
engine to run with a dirty exhaust without
investigating the cause as this may result in an
expensive breakdown.
•
Check and readjust V-belt.
•
Check the electrical connections.
EVERY 150 HOURS:
•
Change oil.
•
Check the battery acid level (not applicable when
Whisper Power
batteries are used).
•
Check battery terminals for corrosion
•
Check and readjust V-belt
EVERY 300 HOURS:
•
Check the impeller of the alternator coolant
pump.
•
Replace the oil filter.
•
Replace the fuel filter
Replacement depends or the condition of the
fuel. We recommend replacement every 300
hours. Isolate the fuel supply and change the
element.
EVERY 500 HOURS:
•
Check the air strainer element and the air filter
element.
•
Replace the impeller of the alternator coolant
pump.
When replacing the impeller the gasket between the pump
case and the cover should be replaced as well. So when
ordering a spare impeller order a gasket as well. Remove
the cover to get access to the impeller. Remove the old
impeller with the help of two screwdrivers. Install the new
impeller and add some grease. Turn the blades in the
direction of rotation of the pump i.e. anti clockwise looking
at the impeller.
EVERY 1000 HOURS:
•
Replace the V-belt.
•
Retighten the cylinder head bolts and adjust the
valve clearance. (Refer to § 5.4.2).
•
Check and clean the radiators
EVERY 2000 HOURS:
•
Replace or clean the air strainer element and the
air filter element.
•
Check lubricating oil pressure
•
Clean and check or replace fuel injector nozzles
and check injection pressure.
•
Check the air filter element:
The air is taken in via the cover on the alternator.
Below this cover is a spongy material which filters
the air and holds some electrical components
which are cooled by the inlet air. This filter does
not require regular maintenance. Only in very
dusty circumstances this filter should be cleaned.
The spongy material can be washed in solvent or
replaced.
When the generator set runs less than 100
hours a year the oil should be changed yearly
