The requirements of the site for placing ZHY-401, ZHY-601 type Press machine
1.1. The unit should be located in a laboratory or clean industrial environment. The machine
should rest on a level and flat surface such that it will support the unit without shaking.
1.2. Never place the unit in a location where excessive heat, moisture, or corrosive materials
are present.
1.3. 1 meter of space to the left and to the right is required for maintenance.
1.4. Ambient temperature 10～40℃.
2.1. AC 380V±10%/50Hz, 3-phase+earth, 10A
2.2. Power supply lead section≥1.5mm2, earth lead section≥1mm2.
2.3. For power supply, fluctuation of voltage≤10%, fluctuation of frequency≤0.5%, grounding
resistance of ground wire≤10Ω.
〈Attention〉The protective grounding wire MUST be installed.
2.4. The length of unit power cable is 3 meters.
〈Warning〉Before installing the cable of the unit, be sure that the Breaker is OFF.
3. 1. Fill the tank with YB-N46 anti-wear hydraulic fluid. The fluid should be filled just
above the middle level of the indicator.
3. 2. Before installation, check the machine for damage and loose parts.
3. 3. Adjust the electrical contact pressure gauge, setting the lower limit to 3 tons and the
upper limit to 10 tons. Screw the adjusting bolt (Figure 1, 5) to the highest position.
3. 4. Without the press tool in place, turn on the power supply. Turn on the breaker located on
the left door of the machine casing. The indicator light in the operation panel is on.
3. 5. While pushing the lifting button or the falling button, observe the hydraulic cylinder
piston rod, the piston rod will move up or down. If the motor is started and the piston rod
does not move, the motor is most likely to be reversed. Please turn off the power and rewire
the power cables.
3. 6. If operation is normal, keep pushing the lifting button and observe the pointer of the
electrical contact pressure gauge. The cylinder piston should move up. As soon as the pointer
begins to move up, immediately release the button. The piston should move up to the top-end of
the cylinder. Now push the falling button until the piston moves down the bottom-end (and the
pump noise begins changing). Release the button. Repeat the above steps three times to deflate
the cylinder.
4. Press tool installation
4. 1. Setting up the press head (Figure 5,2). The cylinder piston is fully lifted. Clean up
the facet in the piston center hollow (Figure 5,4) and the press head pedestal surface. Put
the press head (Figure 5,2) pedestal surface into the hollow carefully. Tighten the turnbuckle
(Figure 5,3) using the sleeve spanner (Figure 5,1).
4. 2. Setting up the outer sleeve. The press head starts down to the bottom-end. Carefully put
the outer sleeve into the nesting and rotate it clockwise 90 degrees. The outer sleeve setup is
complete.
4. 3. Carefully push lifting button until the press head moves smoothly into the outer sleeve
hole.
〈Attention〉Boric acid, aluminum cup, steel ring and plastic ring tools are different from
each other. Follow specified installation instructions carefully.
