To properly install an attachment on your KOBALT KMH 1040-03 Brushless Power Head, follow these steps. First, remove the pack for safety. Next, loosen the wing (A). The power head has two grooves on the coupler (B), but only use groove 1 for KMS 1040-03 and KEG 1040-03 attachments. Align the spring-loaded pin on the attachment with the groove on the coupler (B) and push the attachment shaft into the power head shaft until the pin pops out and you hear a click. Pull the attachment shaft to confirm it's securely locked. Finally, tighten the wing (A) securely. To remove an attachment, remove the battery pack, loosen the wing (A), and press down the spring-loaded pin while pulling the attachment shaft out of the coupler. Always handle the power head and attachments carefully and ensure the battery is removed before any adjustments.
