Using the Milwaukee 2774 - 21HD hydraulic pump is easy. First, make sure the battery is fully charged. Connect the pump to the appropriate hydraulic hoses and heads. You can use the bucket hanger accessory to get a stable operating position. There are three operation modes - Auto - Dump, Hold - Pressure, and Remote Cut. Choose the mode that suits your task. When using Wireless Mode, you can keep a safe distance from potentially live cables. The battery check feature will tell you if there's enough charge for your application. As for maintenance, keep the pump clean. The weather - protected electronics help keep dirt and dust out, but it's still a good idea to wipe it down after use. Check the battery regularly and follow the charging instructions for the M18™ and M12™ Rapid Charger. Also, make sure to store the pump in a dry place when not in use.
