Proofreading and improving User Manuals (English)

Looking for experienced freelancer to thoroughly proofread the 2x user manuals and make necessary improvements/revisions. I want to make sure user manuals are well written and easy to read. I would like to keep these in plain English and no jargons. All corrections and changes must be highlighted either in different colour or track changes so I can identify what's changed.

Following checks are required:
- Grammar
- Punctuation
- Spellings
- Formatting and spacing

Both user manuals are attached.

Please only send proposal if you have excellent English skills (reading and writing) and you have good attention to detail. This work is urgent therefore must be completed in one day. Please bear this in mind when sending proposals.

Thanks.
