Crytec Power 24" Portable Chainsaw Saw Mill - Milling Attachment Lumber Planking

The parcel arrived promptly and all the parts were well packed. I found the assembly instructions useful but only up to a point, because some of the items were wrongly numbered on the sheet.
This is supposed to be instructions of 'assembly and operation'. There is NO information about how to use the device at all. How do you use this to make the first cut? The video on your website is pathetic, only highlighting what not to do. FAIL it keeps saying - Great!
The calibrations on the uprights are very poorly marked fading to nothing down one side. Also, what is the chrome rod for? I cannot see its purpose.
I am now using it in my own way and getting some success. This experience has at least taught me to adapt these marketed goods/tools to my own needs as I have seen others do but always felt that were being rather arrogant - not any more.
I am still satisfied that I bought it. This is better than nothing.
