11. MAINTENANCE INSTRUCTIONS
11.1 Crank mechanism maintenance.
Check oil level at least on a weekly basis (Fig. 8).
If necessary, add the missing oil through the oil plug
(position 1, Fig. 8). Check oil level when the pump is at
room temperature. When changing the oil (removing the
plug position 3, Fig. 8), the pump should be at its work-
ing temperature.
Change oil every 1000 working hours, oil pump capacity
is 2 litres.
In any case the oil should be changed at least once
a year, since oxidation deteriorates it.
Mineral or synthetic oils can be used but they must be
chosen according to the working environment
temperature. Here below is a diagram indicating viscosity
according to room temperature.
