Intermittent speed and intermittent pressure drop must not occur simultaneously! 2. Recommended filtration is per ISO cleanliness code /16. A nominal filtration of 25 micron or better.. Recommended using a premium quality, anti-wear type mineral based hydraulic oil HLP(DIN51524) or HM (ISO 674/4). If using synthetic fluids consult the factory for alternative seal materials. 4. Recommended minimum oil viscosity 1 mm²/s at operating temperatures. 5. Recommended maximum system operating temperature - 82ºC. 6. To assure optimum motor life fill with fluid prior to loading and run at moderate load and speed for -15 min. 25
