4.11.1 Maintenance Batteries
WARNING
Take out the protective cover above the t a p s
and tear down the air outlet taps.
Fill the battery with a clean accumulator acid
having a density of 1.280 at 20 °C until the point
15 mm. above plates. Battery an acid teperature
must above 10 °C.
Let the battery to stand still 15 minutes. After
that point battery pockets will start to become
heated and gas bubbles will rise at the surface of
electrolyte.
Attach the air outlet taps to their place.
After waiting at least 15 min. control the battery
with a hydrometer.
Minimum charge time is 6 hours. If the charge
voltage and electrolyte level does not increase in
at least one hour period that means battery has
been charged.
Control the electrolyte level after two hours
from the charge and if necessary add distilled
water so that it is 10 mm. above plates.
4.11.1.1 First filling of Acid Water
to the battery
Do not smoke or allow sparks, flames or other
sources of ignition around batteries. Hydrogen
gas generated by charging batteries is explosive.
Wear an acid resistant apron and face shield or
goggles when servicing the battery. If electrolyte
is spilled on skin or clothing, flush immediately
with largequantities of water.
Take out the metalic things in your wrist and
protect your wrist and hand.
Disconnect the battery negative (earth) lead first
and reconnect last.
Always ensure that battery charging is carried
out in a well ventilated area.
The starting batteries should be located as close
as possible to the generating set while still being
accessible for servicing. This will prevent electrical
losses from long cale that could impact on the
engine starting capability of the batteries.

The American Petroleum Institute (API) the
American Society for Testing and Materials
(ASTM) and Society of Automotive Engineers
(SAE) has developed and preserved a system in
order to classify the lubrication oils for their
performance categories.

4.10 LUBRICATION OIL
Oil system of diesel engine is one of the most
important elements of the engine. Correctly
made engine overhaul (this subjet includes oil
change periods, filter change periods, paying
attention about selecting the true type of oil)
prolongs the life of the engine and it decreases
the life cycle cost of the engine.
4.10.1 Oil Performance Properties
Recommended lubriation oil specifications for
Perkins Diesel Engines:
If the ambient temperature of the engine is above
-15ºC, use lubricating oil as SAE 15W/40. If
a m b i e n t t e m p e r a t u r e i s a b o v e
-15ºC and below 25ºC, 10W/30 grade lubricating
oil is recommended. API CH-4 classification is
required to neet Perkins oil change intervals.

4.10.3 Lubricating oil
recommendations by Lister Petter
To help assist engine running, all engines are
dispatched with an initial fill lubricating oil which
must be changed after 100 hours.
Lister Petter engine manufacturer recommends
the following oils;
API CC Def2101 D MIL-L-46152 B
MIL-L-2104 B
