Setup
1. Charging the Battery
The unit is powered by a 7.2-volt lithium-ion battery. Before first use, fully charge the battery. Connect the charger to the charging port on the main unit. The indicator light on the charger will show charging status. Once fully charged, disconnect the charger.
2. Attaching the Extension Pole

The Sun Joe HJ605CC-GRY comes with two interchangeable blades: a 4-inch grass shear blade and a 6-inch hedge trimmer blade.

Insert the desired blade, ensuring it aligns correctly with the internal mechanism, and replace the blade cover.
