1.2 Structure of Pump & Valve
Fig.1 Structure of Pump
The pump contains motor, pump head, tank, liquid level switch, cooling system, etc..
The viscosity of hydraulic fluid shall be 4~1500
s
mm 2in which the best practise is
Ⅱ

10~500
s
mm 2. The temperature shall be -25℃—+80℃. Depress the rivet tool in air for
several circles before use to make sure the hydraulic fluid fully fills the hydraulic system.
Fig. 2 Structure of Valves
The valves contains master limiting valve, unloading valve, pressure limiting valve of
B way, unloading changeover valve, magnetic directional valve, filter system, manifold
block.
1.3 Hydraulic Tube
The hydraulic tube is equipped with high-pressure tube sourcing from CEJN, and
quick disconnect couplers from Paker(paker371、paker372).
Recommended Hydraulic Fluid: 32# Anti-wear Hydraulic Fluid (temperature at
-12℃~20℃) & 46# Anti-wear Hydraulic Fluid (temperature at 20℃~50℃).

2. Principle of Operation
1 Hydraulic pump aggregate 7 Solenoid valve
2 Directional valve 8 Pressure relay
3 Unloading valve 9 Pressure-limiting valve
4 Overflow valve 10 Two-way solenoid valve
5 Pressure transmitter 11 Strainer
6 Installation tool
Fig. 3 Principle Diagram
When the tool trigger is depressed, motor runs, DT1 is powered on, and the left
contact of four-way solenoid closed, then the hydraulic unit start PULL circle. When
PULL pressure reaches to a pre-set value, the DT1 is shut down, and the right contact of
four-way solenoid closed, then the hydraulic unit start RETURN circle. When PUSH
pressure reaches a pre-set value, the motor shut down, and DT2 is powered on for 1s, the
pressure is released. See below for the action of solenoid valve.

3.2 Adjusting the Pressure Setting
Fig. 4 Adjusting the Pressure
3.2.1 Master Regulating Valve for regulating the PULL pressure of installation and
cutting tool:
a. Turn the valve clockwise to rise the pull pressure;
b. Turn the valve counterclockwise to decrease the pull pressure.
3.2.2 Return Regulating Valve for regulating the RETURN pressure:
a. Loosen the locknut (white nut) on the valve;
b. Start pumping;
c. With a screwdriver, slowly turn the adjusting screw(black screw);
d. Turn the adjusting screw clockwise to rise the pressure, turn the adjusting screw
counterclockwise to decrease the pressure;
e. When the desired pressure is reached, lock the adjusting screw in position by
tightening the locknut while hold the position of the adjusting screw.

4. Preparation for Operation
a. Repairman and Operator must read manual prior to using equipment. A training
session with qualified personnel is recommended before using this equipment.
b. Check all hoses and tools for damage and leaks. The leaks of hydraulic fluid
leads to severe personal injury.
c. Keep the coupler of pipe away from dirt. Any dirt or fiber leads to defect and
must be cleaned up prior to using this equipment.
d. The thread sealant tape is recommended to seal the thread of pipe to avoid
leakage. DO NOT use plastic tape to enwind the thread of pipe, the chippings of plastic
tape leads to damage to valve.
e. Before connecting the tool trigger to hydraulic unit, the hydraulic pipe must be
connected to the hydraulic unit first.
5. Maintenance & Cautions
a. Keep the hydraulic unit clean.
b. Replace the hydraulic fluid once running for every 250 hours.
c. Disconnect the power supply of hydraulic unit while it is not supposed to be
used.
d. Inspect the level of hydraulic fluid regularly, add fluid as needed.
e. Do not move the hydraulic unit by hauling the pipes; protect the structure shell
from damage; protect the hydraulic unit from falling when moving it.
f. Inspect all pipes and hoses for signs of damage and leaks, replace the hoses and
accessories as needed.
g. Inspect all connection of tools everyday before work.
h. Regularly inspect the screws of tool and hydraulic unit for loosening.
i. Take care of all connections from break, scrap and joint failure when using this
hydraulic unit.
