Cleaning and Servicing 8.4 Checking the float switch  Whenever the coolant is changed, the function of the float switch must be checked. The float must move freely and it will sag down by its own weight, when the coolant tank is empty. With full coolant tank, (float under surface level) the float will stay in horizontal position, the switch is closed.  If the float does not work properly, try to clean it carefully with a damp rag and mild cleaning agents. Do not use cleaning agents containing any solvent. Do not damage the float.  If cleaning does not restore function, or if there is any damage to the connector or to the cable, the float switch must be replaced.  The float switch is a safety device and must not be repaired. 8.5 Replacing the float switch Attention: prior to service the machine must be disconnected from its power supply and from the compressed air system (see Chapter 2, Safety, page 9)  To remove the float switch, please disconnect connector from the generator module.  Remove plastic hex nut (22mm hex) and pull the wire with the old switch through the hole.  Replace float switch and align properly, so the float hangs down. The float must move freely by its own weight. Tighten plastic hex nut with a torque of 4Nm (2.95 lbf*ft)  Replace connector to the generator module. Do not kink or pinch the cable. The cable should not have any tension. October 2015 ISG3410 42
