keep a spare seal kit, as its a pain if it goes down mid tourne, (make sure u get the right one i.e. low or high pressure),
strip clean and regrease every 3 months or so (helps keep the consistancy of the reg), use the instruction manual on the smartparts web site as some of the o-ring need to be left grease free.
fill with the on/off in the off postion, then remember to turn it on BEFORE the game
other than that one of the best regs available
