We’re sorry the instructions are unclear! There is no official video tutorial for this harness installation, but here are the exact steps to attach it correctly:
Locate the metal eyelet on the trimmer shaft and hook the harness to it.
Put on the double shoulder harness like a backpack and fasten the chest/waist buckle.
Adjust the strap lengths for even weight distribution.
Clip the trimmer’s locking bar into the harness hook to secure it.
Please let me know if you need further help step by step.
