Car maintenance and inspection. Before commencing maintenance and inspection, the vehicle should be washed and cleaned. It is necessary to protect the lubrication points against the introduction of contaminants into the cooperating parts and to protect employees against eye contamination., inhalation of dust and contamination of clothes. Lubrication works are the most time-consuming during maintenance. So positions, on which these activities are performed, should be equipped with appropriate lubrication sets, e.g. grease guns, undercarriage spray equipment, portable gear oil distributor etc.. Many service stations use foot or hand operated grease guns with solid grease instead of grease kits. These lubricators can lubricate the linkage joints in the steering linkage. Keep your hands clean when carrying out lubrication work on vehicles running on leaded petrol. After work, especially before a meal, wash your hands with kerosene (if they are dirty with used engine oil), and then in warm soapy water.
