220V 750W Electrical Self-priming Gear Oil/diesel Oil Transport Pump Oil Filling Machine 

50-70L Hydraulic Oil Pumping Pump

Liquids that cannot be pumped:
Gasoline, gear oil, water, urea, acid and alkaline liquids, corrosive liquids, chemical liquids, edible liquids, etc.
Each machine is air pressure tested before leaving the factory to ensure the overall tightness of the pump body and avoid oil leakage.

Precaution:
1. Not suitable for filling gasoline, alcohol, liquefied petroleum gas and high viscosity engine oil with low ignition point
⒉. Before use, confirm whether the voltage of the power supply is consistent with that of the oil pump.
3. The DC pump power supply has (+) (one) level, and the red line is positive, otherwise the oil pump reverses and does not discharge oil.
4. The oil inlet and outlet pipes are as indicated by the arrows, and the oil inlet pipes and joints must not leak to ensure the suction stroke.
5. Remember to install a matching filter on the oil inlet pipe to prevent hard debris from sucking into the pump cavity and damaging the pump core. The blades should always be cleaned of dirt on the surface of the filter screen, otherwise the filter screen can easily cause flow reduction and pump damage.
6. The oil pump can work continuously, no oil-free idling should not exceed five minutes, so as to avoid damage to the pump core, oil seal and vanes due to friction and heating.
7. Do not modify, disassemble or extend the power cord without authorization.
8. If the power source uses a battery, make sure that the battery is fully charged.
