String Trimmers

Have a 128LDX with hedge and string trimmer attachments. Even when new, depressing the lock and attaching an accessory was difficult. I’ve used lubricants —it’s still a hit or miss task

Currently, I am unable to attach anything. It’s maybe a year old. I haven’t misused it. The design of the attachments is extremely flawed

Any ideas on how I might make just attaching accessories easier?
