Before use, first add 9L of hydraulic oil to the oil tank, check whether the oil pipe joints and fasteners are loose, and tighten them if they are loose to prevent oil leakage from affecting use. Check if the grounding and fuse of the electrical components are effective. 2. Procedure for demolding: At the beginning, turn the left return valve to the open position and the right delivery valve to the fast position. Then press the start button to turn on the power, and the oil pump starts working. Tighten the return valve clockwise, and slowly open the delivery valve to raise the piston a certain distance. Observe for any abnormal phenomena such as jamming. If there are any, stop the machine for inspection and troubleshooting. If there are no abnormal phenomena, the piston should be raised to the limit to return oil, in order to exhaust the air in the hydraulic system. Observe that there are no bubbles in the return oil pipe on the left cylinder, and it can be used normally. When demolding, attention should be paid to the accurate positioning of the mold barrel, which is the key to the smooth operation of the instrument and demolding. Due to the different sizes and structures of various compaction test molds, this machine adopts three different positioning methods for test molds and is equipped with corresponding accessories, making it easy and reliable to use. (1) The anti-seepage test mold, compaction test mold, and Marshall compaction test mold can be directly removed with a ￠ 160mm shim (the end of the test mold barrel with a flange facing upwards)

Maintenance and Care

1. The inside and outside of the instrument should be kept clean to prevent rusting of all parts. 2. Regularly check whether the oil is clean. According to usage, the hydraulic oil in the oil tank should be settled once a month, and the hydraulic oil should be replaced every six months. When changing the oil, the oil tank filter should be cleaned. If the oil is found to be severely turbid, it should be replaced in a timely manner, otherwise it will accelerate the wear of various parts of the hydraulic system and even affect normal operation. The hydraulic oil specifications, depending on the temperature, are recommended as follows:

(1) When the ambient temperature is 15 ± 5 C, use GB443-84N46

(2) When the ambient temperature is 25 ± 5 C, use GB443-84N68
