Hydraulic System - Volvo Penta TAMD60A Instruction Book

7. Hydraulic system, oil level
AQD70. Optional equipment for all other engines.
Check the level after every 50 hours of operation. The eng-
ine should be idling.
1. Remove the filler cap on the hydraulic tank.
2. Wipe the dipstick, and check the level which should be
at the max. mark on the dipstick.
3. Fill with engine oil, if necessary. The oil quality is the
same as in the engine,
8. Checking batteries
Check the electrolyte level in the batteries every 50 hours
or more often. The level should be about 10 mm above the
cell plates. Top-up with distilled water if necessary. Also
make sure that the cable terminals are properly tightened
and greased.
Check the state of charge of the batteries with the aid of a
hydrometer if the voltage is low.
The density of the electrolyte should be 1.28 g/cm
fallen to 1.23 the batteries should be re-charged. If a rapid
charger is used, first disconnect the battery cables, (both
the + and the - cables).
Every 100 hours
9. Engine, changing oil
Change the oil in the engine after every 100 hours of ope-
ration and when the engine is warm. However, during the
running-in period the oil should be changed for the first
time after 25 hours of operation. Do not use flushing oil for
cleaning the crankcase. Only drain (pump out) the old oil
carefully.
NOTE!
Collect the old oil carefully and hand it over to a service
station or disposal depot. Never pollute the water by dis-
carding the oil over board.
AQD70C, TAMD70C, changing oil
1. Open the cock at the oil scavenging pump (position 1)
and pump the oil over into a vessel.
2. Close the cock and fill with engine oil through one of
the rocker arm casings after the ventilation cap has
been removed. See page 21 concerning the amount of
oil to be filled.
3. Start the engine and allow it to idle for a minute or so.
4. Stop the engine and check the oil level. Top up if
necessary. Note! The cock at the scavenging pump
should be closed when the engine is running. Posi-
