Bought one of these to supplement the Mac 338 that I have used for years as I now have had to take down some larger trees to source wood for the log burning stove that we have installed. The first thing that strikes you about the 842 is that it is considerable bulkier and heavier compared with the 338. Saw is easy to start: prime using the bulb (3 or 4 presses), choke on, 3 pulls until it coughs and then a final pull on half choke. Works every time. Test the brake on full throttle and you are set to go. Saw works well and has tackled trees up to 22 inches in diameter without too much fuss - just make sure that the lube is getting through and clear the cut occasionally. I have gone through 3 chains now (but have cut a lot of wood in the process) and the saw is holding up very well mechanically. Only 2 issues are firstly that the sprocket wears quite quickly and is expensive to replace (£29 each from McCulloch) compared with a Stihl or Husqvarna sprocket (which you can find for around £6-12 ea); secondly, as the chain is a thin home use chain the edge can go off relatively quickly if you are cutting hardwood such as Oak or Cherry - though a regular touch with a file works wonders. Its also worth noting that Oregon and Carlton do chains and bars for McCulloch that are very good quality (OEM for many manufacturers) and are much cheaper compared with McCulloch parts. One other minor issue is that you need to check that the locking tab on the chain tensioner is locked down on a regular basis as it has a tendency to vibrate loose allowing the chain to slacken - which if not caught can be a safety issue. If you intend to do serious cutting (and a 9 kw log burner uses a lot of logs in a year), then buy a Stihl/Husky or Makita semi-pro saw (at £350-£500). If you are happy for occasional use, then the Mac is a very sound tool for the task - pays your money and makes your choice. Given the amount of wood I am now cutting, I will likely change to a Makita DCS 500 which is much more powerful and robust. In sum, the 842 has been a reasonable purchase given the limits described above. Finally whatever you do - buy the safety kit (trousers, Gloves, helmet and boots). I witnessed the after effect of a chainsaw accident several years ago and it's not pretty - all it takes is 1 second's lack of concentration. For £100 extra it could save a limb!!!!!!
