3.4 - INSTRUCTIONS FOR USE AND MAINTENANCE OF THE HYDRAULIC MOTOR

Ensure the direction of rotation is consistent with the circuit connections.
TANK: The tank capacity must be in accordance with the operating conditions of the system.
A heat exchanger should be installed if necessary. The intake and return lines in the tank must be spaced apart (by inserting a vertical
divider) to prevent the return-line oil from being taken up again immediately.
PIPING: The lines must have a nominal diameter which is at least as large as the openings of the engine and must be perfectly
sealed. A length of flexible tubing is recommended to reduce the transmission of vibrations. All return lines must end below the
minimum oil level, to prevent foaming.
FILTRATION: We recommend filtering the entire system flow.
HYDRAULIC FLUID: Use hydraulic fluid conforming to the ISO/DIN standards. Avoid using mixtures of different oils which
could result in decomposition and reduction of the oil's lubricating power.
DRAINAGE HOLE: in bidirectional motors with drainage hole, connect the hole with the oil tank with a pipe. 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.
PROBLEM- SHOOTING: 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 case, the
last option is more affordable and less invasive on a system that already exists as it does not require an additional hole in the tank.
