三、注意事项：

◆ 使用前应先检查油箱内的油液是否充足，可察看右侧面油标，如不足，则应打开后箱板向油箱内添加之，至液面在油标处为宜。

◆检查各油灌接头和紧固件是否松动，如有松动则拧紧之。检查防尘罩应完整无损。检查电气接地、保险熔丝等安全防护措施是否有效。

◆ 首次使用时，应先将回油阀打开，关闭回油阀，接通电源，按下启动按钮，油泵开始工作，然后关闭回油阀，徐徐打开送不油阀，活塞上升一段距离，有无卡住等现象。如有，则应卸荷、停机检查，并排除之。打开回油阀，活塞则下降到原位。

◆将试件表面擦拭干净，检查外观有无明显缺陷，如有能影响试验数值者，须更换无损试件。

◆按试件下压板定位线框放在下压板正中，并按试件大小，转动手轮和丝杠，调节上压板至适当位置。

◆接通测控系统电源(开关在测控箱背后)，按操作步骤进行清零以及时钟修改等各有关数据的输入。

◆按下启动按钮，关闭回油阀，调控送油阀，按需要速率平稳进行加荷试验，及至试件被压碎，负荷下降。随即打开回油阀，使油液迅速流回油箱。

◆试验结束时，按面板上“打印”键。打印机即可打印输出该次的试验报告。

◆操作时，下压板上升高度不得超过4cm(或立柱上标志线)，以免发生意外。

◆操作中禁止手等人体任何部分置于上下压板之间，并注意试件在破碎时碎片崩出伤人。

◆试后随即清除破碎试块，以待下次试验。当不再做试验时，要打开回油阀，关闭送油阀，切断电源。

3. Matters needing attention:

◆ Before use, check whether the oil in the oil tank is sufficient. You can check the oil mark on the right side. If it is not enough, open the rear box plate and add it to the oil tank until the liquid level is at the oil mark.

◆Check whether the oil tank joints and fasteners are loose, and tighten them if they are loose. Check that the dust cover should be intact. Check whether safety protection measures such as electrical grounding and fuse are effective.

◆ When using for the first time, you should first open the oil return valve, close the oil return valve, turn on the power, press the start button, the oil pump starts to work, then close the oil return valve, slowly open the oil delivery valve, the piston rises for a certain distance, No jams and other phenomena. If so, unload, shut down for inspection, and exclude it. Open the oil return valve and the piston will drop to its original position.

◆Wipe the surface of the test piece clean and check the appearance for obvious defects. If there is any defect that can affect the test value, the non-destructive test piece must be replaced.

◆Place the wire frame of the lower platen of the test piece in the middle of the lower plate, and according to the size of the test piece, turn the handwheel and lead screw to adjust the upper platen to the proper position.

◆Turn on the power supply of the measurement and control system (the switch is at the back of the measurement and control box), and follow the operation steps to perform resetting and clock modification and other relevant data input.

◆Press the start button, close the oil return valve, adjust the oil delivery valve, and carry out the loading test at the required rate steadily, until the test piece is crushed and the load drops. Then open the oil return valve to make the oil flow back to the oil tank quickly.

◆At the end of the test, press the "Print" button on the panel. The printer can print out the test report for this time.

◆During operation, the rising height of the lower pressing plate shall not exceed 4cm (or the mark line on the column) to avoid accidents.

◆It is forbidden to place any part of the human body, such as hands, between the upper and lower pressure plates during operation, and pay attention to the fragments of the test piece when it is broken and hurt people.

◆Clear the broken test block immediately after the test for the next test. When the test is no longer being done, open the oil return valve, close the oil delivery valve, and cut off the power supply.
