1. Check whether the oil machine has oil leakage, water leakage, air leakage and electric leakage. External cleaning of the unit, including dust removal of the generator junction box. Change diesel filter, air filter and oil filter.
2. Check the terminal voltage and electrolyte level of the electric start-up battery. The start-up battery should always be in a state of stable voltage and floating charge, and supplement it when the electrolyte is insufficient. Check the amount of fuel in the fuel tank, and fill it in time if it is insufficient.
3. Check the correctness and stability of each accessory device. Check the belt for wear/damage/looseness, and adjust or replace it.
4. Check the body heater to see if it works normally (the temperature in the body should be kept at 32 degrees).
5. Check whether the battery charger works normally and adjust or replace it. Check the operation of all instruments and adjust or replace them if necessary. Check whether the lubricating oil pressure is normal. Inspection and replacement of lubricating oil.
6. electrical system inspection, such as connector inspection, function test (protection system and automation system), frequency inspection and adjustment, voltage inspection and adjustment, check the working condition of generator "AVR" and make corresponding adjustments.
7. Inspection of external connections of the unit (such as leakage and looseness, overall integrity of the unit: fixing and connection of the frame, damping pad, angle wheel, engine and generator).
