Please check the packing list after opening the package. Preserve the maintenance parts and tool. Connect the power supply (AC220V 60Hz). 2. Loosen the handwheel of the oil-draining valve to unload (This press has been pressurized before it leaves the factory.). 3. Check whether the nuts on the columns are tightened. If there are loosened, tighten the columns and then tighten the nuts on the columns. Pay attention to this procedure. 4. Adjust the pressure gauge (red pointer) according to the required pressure.  Notice: The maximum pressurization for this press is 34MPa. 5. Place the testing briquetting under the screw to have a pressure-test. 6. Fasten the screw and the handwheel of the oil-draining valve, and then turn on the power switch (If pressure-holding is required, please adjust the relay of the pressure-holding to the required position.). 7. Check whether all nuts on the machine are tightened before opening the package. Tighten the nuts if they are loosened. 1、开箱后请查看装箱单，并保留好维修备件及专用工具。开箱后请接通AC220V，60HZ电源。 2、松动放油阀手轮泄压（因主机带压出厂）。 3、检查机器立柱上螺母是否有松动。如有松动，请先紧死立柱，再拧紧立柱上的螺母。注意顺序。 4、根据您所需要的压力调整压力表（红色指针）。注意不得超过机器所限最大压力40MPa。 5、请将试压块放在丝杠下进行试压。 6、紧死丝杠，拧紧放油阀手轮，启动电源（如果需要保压定时，请将保压定时继电器调整到需要的位置）。 7、拆箱前请检查仪器所有螺母及螺钉是否拧紧。如有松动，请紧死螺钉。 II.

Principle of Oil Channel IV、【油路原理】 Motor (10) would drive the piston pump through reduction gearbox (13) and swash plate. Then liquid oil would produce pressure after it enters big oil cylinder through oil-suction valve (15) and delivery valve (16). Electric contact pressure gauge (11) would indicate and control the pressure in the system. After it reaches the set pressure, motor (10) would stop working. 电动机10经减速箱13及斜盘来驱动双柱塞泵。液压油经吸油阀15及出油阀16压入大油缸中产生压力，电接点压力表11显示并控制系统中压强，达到所设定的压力后电动机10自动停止工作。松开放油阀7卸压后，大活塞6自动复位。 V. Instruction for Operation V、【操作说明】 (1) Grounding MUST be made before operating the machine. (2) Loosen the oil-filling nut (14)（For reasons of transportation, the nuts of the oil-filling hole are tightened, which affects pressurization. Therefore, they need to be loosened with an inner-hexagon wrench and place them on the machine.）. (3) Turn the pointer (red) of the electric contact pressure gauge to the required position. Notice: The maximum pressurization for this press is 34MPa. (4) Place the mould or the object which need to be pressed on the worktable (5) and fasten the screw (3). (5) Tighten the oil-draining valve (7). (6) Turn on the power switch (17) and press the “start” button, then the machine would work. When it reaches the required pressure, the machine would automatically stop working.   (7)  Loosen the oil-draining valve (7) and press the “stop” button, then the working process is over. 1、电源插头必须有可靠接地。 2、松开注油孔螺钉14（由于运输原因，出厂时压片机的注油孔螺钉是密封的，影响压片机的上压，首次使用时要松开注油孔螺钉）。用内六方扳手将注油孔螺钉松开，浮放在仪器上面。 3、将电接点压力表的上限指针（红色）调到所需压力位置。注：压片机最大的压力是34MPa。 4、将模具或需加压物品放在工作台5上，并旋紧丝杠3。 5、拧紧放油阀7。 6、打开电源开关1，按下启动开关即可工作。当达到定压力时，电动机停止工作。 7、松开放油阀7，按下停止按钮，工作完毕。 VI.
