Page 6: Pump Lubrication
Pump Lubrication The pump drive end is splash lubrication and the crankcase oil storage of about 12 liters. When filling oils, remove the vent cap and fill oils through the oil hole. The Crankcase lubricating oil should be 15W/40CD at an ambient temperature of 15 ℃ ~ 40 ℃, 15W/3CD at an ambient temperature of 5 ℃... - Page 7 damaged badly. (4) Before starting, turn on all valves on the inlet and outlet pipes for preparation for no-load start. (5) Before starting, please make sure the inlet and outlet pipe fittings are tightened, to prevent the cavitation caused by air. (6) Before starting, fill the required lubricating oil to the fixed oil level in the case.
