2.18 Regularly apply appropriate lubrication at each lubrication point, specify the use of NO.2 lubricating grease, and ensure that all mechanical parts are properly lubricated
3 Maintenance essentials of direct press oil pressure system
3.1 Avoid melting the glue under the set range before the material temperature is reached, so as to avoid indirect damage to the hydraulic motor
3.2 Avoid pushing heavy objects on and trampling on hydraulic parts
3.3 Clean the inside of the oil tank regularly, replace or clean the oil network
3.4 When the oil pump is running, the oil product and oil pressure circuit should be inspected if abnormal noise occurs
3.5 Check whether the temperature of the circulating oil and the amount of oil in the tank are sufficient at any time
3.6 It is strictly forbidden to mix with water to avoid damage to the hydraulic system
3.7 It is strictly forbidden to pollute the hydraulic oil with dust or plastic
3.8 Pay attention to whether each high-pressure oil pipe is locked and whether there is oil leakage
3.9 Hydraulic oil sampling for inspection or update review
3.10 Review whether the internal dust seal of the hydraulic cylinder is updated
3.11 Regularly check the flow value, pressure value and correction of the oil pressure system
