When I bought my Dimona I soon discovered that someone had filled the lube port with grease. Some of which slobbered down to the drive. I cleaned that mess up when I proactively replaced the mag. I am about to do so again. I figure that the mag, being direct drive, turns and fires twice as often as in usual applications, hence 250 hours may well be the equivalent of 500 hours.
