Features
The hydraulic hand pump has high and low pressure 2-stage design, with fast oil delivery speed. The working pressure and function are the same as the electric pump.
Manual operation mode, oil pipe can be lengthened, with quick joint, pressure gauge (optional).
Pressure can be stopped in the middle of operation, built in high-pressure safety protection hydraulic valve.
Oil tube joint is adapted to PT3/8″ thread.

Hydraulic Hand Pump Usage
Connect the high-pressure oil pipe female joint of the main pump and the male joint of the sub-machine oil pressure cylinder, and tighten them.
Tighten the oil return switch of the pump clockwise, shake the handle repeatedly to advance piston until the work is completed.
After completion, loosen the oil return switch counterclockwise to reset the piston.
Tips: Three reasons for the failure of hydraulic hand pump.
Check the internal leakage of the boom cylinder:The easiest way to do this is to raise the boom and see if it has a noticeable free fall. If the drop is obvious, dismantle the oil cylinder for inspection. If the sealing ring is found to be worn, it should be replaced.
Check the control valve:First clean the safety valve and check whether the valve core is worn, if worn, it should be replaced. If there is still no change after the safety valve is installed, check the wear of the control valve spool again.
Measure the pressure of the hydraulic pump:If the pressure is too low, adjust it, and the pressure still cannot be adjusted up, indicating that the hydraulic pump is seriously worn.
