Quoting: jsahara24 How did the cushion valve change the machine? Its definitely "jerky" but I'm getting used to it the more I use it..
The cushion valve doesn't really change how the machine works. Its more for protection of the slew motor. It essentially adds a small amount of cushion at the end of travel when you spin the machine with a load of dirt. Guys were stripping gears or completely breaking off the slew motors.
For the "jerkiness", you can add springs or small piece of fuel line to the pilot control plungers. It helps for sure, but doesn't completely tame the bronco. Some people will slow things down by adjusting the pressure on the pilot controls. Basically turn it down until the machine doesn't move, then slowly increase it until its where you want it.
A fan will help to solve your gas boiling problem. However, I suggest you keep a close eye on you hydraulic oil temps. 140F (60C) is bad and the oil degrades quickly at those temps. You want to make sure you keep it below that.
