Using your Milwaukee M18 0886 - 20 Jobsite Fan is easy. First, if you're using a battery, make sure it's fully charged. You can also use the included AC adaptor for extended run - time. Turn on the fan and select one of the three speed settings - high, medium, or low - based on your needs. Adjust the head up to 120° and choose from 9 stopping positions to direct the airflow where you want it. You can hang the fan using the keyhole hangers or through the hanging holes on different jobsite materials. When it comes to maintenance, keep the fan clean. Wipe it down regularly with a dry cloth. If it gets dirty, you can use a slightly damp cloth. Make sure the fan is turned off and unplugged before cleaning. Store the fan in a dry place when not in use. Always use compatible M18™ REDLITHIUM™ batteries and handle them according to the manufacturer's instructions. And remember, batteries and charger are sold separately.
