G'day Kim, Just wanted to let you guys know how great the Swiftmelt has been (and continues to be) for me. We use it almost daily, and have learned that we do not need to empty it between jobs since it's effortless to reheat from solid/cold (that's largely due to the viscosity of Permatrack, which melts at a low temp). The simplicity and efficiency of this machine has been even more underlined by the fact I bought a 125kg Merlin mixer (to fit on my Ford Ranger pick-up) which, while very handy for small jobs, is nowhere near as efficient. Also, after 5 years of operation I've had virtually no problems with it... • I had battery issues early on, but they were due to user error (leaving the ignition switch on) • I had a diesel motor issue, which turned out to be stuck valves due to my lack of oiling them, and • just recently, I had a small issue with the battery terminal melting. Lucky it was night time or I might not have noticed the glow from the terminal. It turned out that the positive cable had worn through and was shorting out on the housing for the ignition switch. Managed to destroy a battery, but solved the problem very quickly (taped up the cable, and sheathed it in a section of garden hose). That last one should be something for all Swiftmelt users to look out for during routine maintenance. Just check the wire. Given the relative cost of repairs, it's probably a good idea to double insulate this as I did.
