b) The piston does not fully move back: check the pipe is not blocked by lateral resting forms. It
can be solved with some smooth knocks. Check too the upper screw
c) Oil is leaking from front zone: the reason for this is the continous friction of the internal o-ring.
This o-ring must be from time to time changed according to following way:
1. Drain the oil tank through the upper screw.
2. Loosen the piece Nº 27 with a hexagonal key.
3. Loosen the hexagonal piece Nº 27 with a wrench.
4. Loosen the piece Nº 28 with a hexagonal key.
5. Extract the piston Nº30 piece with the hand.
6. Replace o-ring of the piston (piece Nº39) , making sure it is correctly positioned.
7. Introduce the piston with smoothness to avoid to damage the o-ring.
8. Introduce and tighten the piece Nº28 with a hexagonal key.
9. Introduce and tighten the piece Nº33 witha key.
