⑤ During use, check whether the amount of oil in the oil cylinder is less than 1/4 of the cylinder volume to prevent the cylinder from overheating and causing danger.
⑥ Check whether there is leakage and gas leakage at the joint of the oil circuit sealing ring parts. ⑦ The remaining gas should be released after use.
