y oil spillage immediately with an oil-binding agent. Screw in the oil drain plug. Note: Check the condition of the sealing ring (the sealing ring is vulcanised onto the oil drain plug); if necessary, use new oil drain plug. Clean the oil filter in the oil-cooling system (see Operating Instructions of Oil Supply System). 1.2.3 Cleaning air filter If layer of dust has built up, the air filter must be cleaned, whether or not the minimum period of 3 months has expired. To do this, the air filter is removed, cleaned with benzine or similar agent and dried, or it can be cleaned by blowing out with compressed air. Foreign bodies must be prevented from entering the gear unit. 1.2.4 Cleaning the gear unit Remove any dirt adhering to the gear unit, using hard brush. Remove any corrosion. The gear unit must not be cleaned with high-pressure cleaning equipment. 1.2.5 Checking cooling coil Stop the gear unit by switching off the drive assembly. Secure the drive unit to prevent it from being started up unintentionally. Attach warning notice to the start switch. Disconnect the water in- and outflow pipes from the cooling coil. Check the inside walls of the cooling coil for deposits. If the cooling coil is dirty, heat is no longer withdrawn effectively from the gear unit. Any dirt adhering to the inside of the coil should be removed by chemical cleaning or the coil should replaced with new one. If thick deposits have formed on the inside of the cooling coil, the cooling water (or the deposits themselves) should be chemically analysed. These analyses are carried out by companies whichspecialise in chemical cleaning. They and also supply the special cleaning agents required. Before using these cleaning agents, ensure that they will not damage the coil materials (contact FLENDER). Observe the manufacturers instructions at all times when using dif ferent cleaning agents by several manufacturers. Avoid burns when working with corrosive cleaning agents. A
