• Bleed nut
  When using hydraulic hand pump, must loosen this nut to prevent the oil reservoir from being sealed. The vent port is the oil filler.
• Optional pressure gauge
  According to requirements, a shock-resistant pressure gauge can be added on oil outlet of the hydraulic hand pump head, to observe pressure changes at any time.
• Oil return switch
  Tighten the oil return valve clockwise first, and shake the handle up and down. Hydraulic hand pump starts to work and the pressure gradually rises. Tighten the oil return valve clockwise when working. Loosen the oil return valve counterclockwise when releasing pressure.
• Quick female connector
  Hydraulic oil tube is equipped with a thread quick connector. Thread specification is 3/8”.

Hydraulic Hand Pump Usage

1. 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.
2. Tighten the oil return switch of the pump clockwise, shake the handle repeatedly to advance piston until the work is completed.
3. After completion, loosen the oil return switch counterclockwise to reset the piston.

Tips: Why the boom cannot be lifted with load of hydraulic hand pump.

1. The hydraulic pump is seriously worn. When running at low speed, the internal leakage of the pump is serious; when running at high speed, the pump pressure is slightly increased, but due to the wear and internal leakage of the pump, the volumetric efficiency drops significantly, and it is difficult to reach the rated pressure. The long-term operation of the hydraulic pump aggravates the wear and the oil temperature rises, which causes the wear of the hydraulic components and the aging and damage of the seals, the loss of the sealing ability, the deterioration of the hydraulic oil, and finally the failure occurs.
2. The selection of hydraulic components is unreasonable. The specifications of the boom cylinder are 70/40 non-standard series, and the seals are also non-standard parts, which are expensive to manufacture and inconvenient to replace. The small cylinder diameter of the boom cylinder is bound to make the set pressure of the system high.
