operating conditions.
• If available, reinsert the screw plugs.
If the motor is equipped with drain plugs, then the water can drain away by itself.

Individual machine parts can become hot in operation. Burns can result when coming into
contact with these parts.
• Never touch machine parts during operation.
• Allow the machine to cool down before starting work.
• Check the temperature of parts before touching them. If required, wear suitable protective
equipment.
