To make the high-speed nail making machine play its due performance and extend its service life, scientific maintenance is essential. The cables of the power transmission switch configured for the machine tool and the cables used for the main circuit switch must meet the power requirements. Ensure that the protective connection wire that is not less than the cross-section of the phase conductor is firmly connected to the PE terminal of the machine tool. Before connecting to the power supply, carefully check whether the electrical system is in good condition, and pay attention to whether the motor is damp. Fill the oil tank to the oil mark, check and refill if necessary. All switches and operating handles should be flexible, smooth and easy to use. To check their movement. For lubrication points, oil types and corresponding oil levels, refer to the lubrication label. Check whether the motor, gears and other parts emit abnormal noise. Check the lubrication of each sliding part. When the machine tool is working, check the working condition of the oil pump at the same time to ensure that it works normally and effectively. Check whether the protective cover and safety protection device are in good condition. Check the tightness of the belt. If the belt is worn too severely, it should be adjusted and replaced in time. Clean up the debris in the inlet mouth to avoid clogging. Before leaving get off work or leaving the machine tool, turn off the main power switch, clean the machine tool, and remove iron filings.
