2, all the screws must be tightened
3, the pump during operation, the lubricating oil temperature should not exceed 70 ° C, the medium temperature of not more than 55 ° C
4, the Shell grade lubricants can withstand S2G > 20
5, note the lubricating oil must be injected from the injection hole (remove vent cap is the oil hole), lubricating oil injection volume of approx. 18 litres
6, oil injection, must be approved by the 80 - 100 to the filter net, filter implantation. To prevent the impurities in the crankcase oil injection in vivo
7, observe the oil pump operation condition, the oil pressure of lubricating oil is maintained at 0.1 - 0.15MPa, oil can be observed from the transparent hose, oil of HERSHEY'S yellow transparent oily, poor gray opaque, black oil difference, under normal circumstances is black when it should be replaced
8, the lubrication system, the filter should be cleaned at any time over the network, if the filter oil filter must be damaged replacement

5, work longer should adjust the sealing ring, check the valve seat on the check valve, spring is worn, replace if necessary
6, use special tool screwing the locking nut, is closely connected to check the piston and the middle rod, must pay close attention to
Seal
7, leakage should be replaced
8, the pump should be installed horizontally, before installation should be carefully check all parts, below the intact condition can be installed
