Replacing fuel filter

Filter change depends on contamination of the fuel, but
should be done however, at least every 1000 running
hours. Before changing the filter, clamp off the supply line.
Remove the hoses from filter and attach them on the new
filter again. The arrow on the filter housing indicates the
direction of the flow. A clogged filter results in a lack of
output of the generating set.
4.2.5

Cleaning oil strainer

The oil strainer is behind a plug on the bottom of the
engine (refer to figure 2, no. 35). In the strainer is a
magnet to catch the metal parts which are in the
lubricating oil. Once per 1000 hours or when the oil is
contaminated one can clean the strainer by washing it with
petrol or a solvent. A green rubber plug in the capsule
gives access to the strainer. Before taking out the plug one
should sump the oil. Use tissues to avoid spilling oil in the
capsule.

REGULAR MAINTENANCE

CHECK DAILY:
•
Oil level (see fig. 13) Take care the oil level is
never below the mark.
•
Coolant level
•
Hoses for loose connections or deterioration.
1 Filling cap
2 Minimum oil level
3 Maximum oil level
Figure 13
AFTER FIRST 50 HOURS:
•
Change oil.
Have the engine run until it is on temperature and
stop it. 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.
•
Check the valve clearance.
•
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.
EVERY 150 HOURS:
•
Change oil.
•
Check the battery acid level.
•
Check battery terminals for corrosion
