Page 98 Fill with oil through oil fill cap and check oil fill volume until specific scale position on dipstick is reached. Cap oil filling port. Start engine; run it unloaded at low speed for 5 minutes. Check engine oil pressure indicator (red) on monitor to make sure it goes off.
Page 99 until packing surface contacts sealing surface of filter holder. Use wrench to fasten 2/3 turns. Pay attention not to over tighten. Note: With filter replaced, it‘s necessary to bleed air from fuel system. 5.5.2.4 Clean Oil Suction Filter Warning  With engine shut, parts and oil are at high temperature which may lead to serious burns.
Page 100 Clean Oil Returning Filter 5.5.2.5 Warning  With engine shut, parts and oil are still at high temperature. Wait for engine to cool down, before starting operation.  There is pressure inside hydraulic oil tank. Release pressure before opening oil fill cap located on top of hydraulic oil tank.
