“I love this sawmill, it cuts great and runs smoothly. It had a few more pieces to assemble than I anticipated so prepare for spending some substantial time for assembly - however other brands would take even longer as the Frontier OS31 comes with the sawhead/engine section already assembled which was very nice. I requested a PDF and printed copies of the owner/assembly manual as the one in my crate was for the OS23 not the OS31 so I had to look online at a lot of pictures to assemble it as the OS23 is substantially different - I have never gotten a response from Frontier on this. I am also still waiting (over 6 months) for the auto-lube system that I ordered, and still waiting (over 3 months) for the track extension and a few other items, to ship to me. I cannot seem to get any response to my emails asking about shipping of these items - they are not shown as "out of stock" on their website so I don't know what the issue is. It would have gotten 5 stars if they had at least replied to my messages let alone shipped the manual that I should have had initially, and shipped the two complete orders that I have outstanding for over 3 and 6 months.”
