justment is very important. Any delay in

To Bleed Oil Lines :
All oil lines should be full of oil. If required, bleed
the main oil line (between tank and pump) by loos-
ening the bleeder screw until all air has escaped
from the line.
Make sure the tank is sufficiently filled.
Check the small oil lines (between pump and in-
take manifold). If required, fill the lines by running
the engine at idle speed while holding the pump
lever in fully open position.
