DRAIN HOLE: in the bi-directional motors with drain hole, the hole must be connected to the oil tank through a hose of at least 22
mm of diameter. To avoid the forming of foam inside the tank, the hose must be connected below the minimum level.
STARTING UP. Check that all circuit connections are exact and that the entire system is completely clean. Insert the oil in the tank,
using a filter. Bleed the circuit to assist in filling. Set the pressure relief valves to the lowest possible setting. Turn on the system for
a few moments at minimum speed, then bleed the circuit again and check the level of oil in the tank. If the temperature difference
between engine and fluid exceeds 10°C, rapidly switch the system on and off to heat it up gradually. Then gradually increase the
pressure and speed of rotation until the pre-set operating levels as specified in the catalogue are attained.
PERIODICAL CHECKS – MAINTENANCE Keep the outer surface clean. Replace filters regularly to keep the fluid clean. The
oil level must be checked and replaced periodically depending on the system's operating conditions.
RESOLUTION OF PROBLEMS: If the circuit is open (i.e. downstream of the engine there is the oil tank and not the pump)
where the engine continues to rotate with the engine off, this is not a case of overpressure but of cavitation. To solve the problem,
a uni-directional valve is required which would convey the oil, or part of it via calibration, from the engine delivery to its inlet in
order to prevent the engine pumping air.
- The circuit is closed. There may be overpressure. To resolve the problem either install an overpressure relief valve, as we
recommend in the attached system diagram, or a calibrated uni-directional valve that partly bypasses the engine. Compared to
the first solution, the latter option is cheaper and less invasive on an existing system as it does not require an additional hole in
the tank.
