Getting Started With Super Santa Kicker 2
I've been running Super Santa Kicker 2 on my shop floor for about three years now, and it's honestly one of those tools that only makes sense once you've broken a few things trying to figure it out. The basics are simple enough — it's a pneumatic kicking unit used primarily for aligning and seating components during assembly line work. You mount it, pressurize it, and it delivers a controlled impact. That's it on paper. In practice, there are a lot more moving parts to get right. The unit itself is a compact hydraulic-pneumatic hybrid. It uses compressed air to build pressure in a small reservoir, then releases it through a solenoid valve to drive a piston. The piston strikes a kick pad that transfers force to whatever you're working on. Most people use it for pressing bearings, aligning shafts, or seating pins without damaging surrounding material. The "2" in the name refers to the second-generation model, which added adjustable force settings and a redesigned seal that lasts roughly three times longer than the original. If you're looking at buying one, make sure you're not accidentally purchasing the v1 and expecting modern performance. The v1 had a habit of leaking around 40% of its rated pressure after about six months of continuous use.
Installation and Setup
Mounting is straightforward if you take your time. The unit comes with four 10mm bolt holes spaced at 75mm by 50mm. Use thread-locking compound on those bolts — I learned that the hard way after the unit vibrated loose during a high-cycle run and took out a neighbor's sensor assembly. Connect your air supply to the 1/4" NPT fitting on the side. Regulate it down to between 60 and 90 PSI. Anything above 90 and you'll start exceeding the designed force output, which defeats the whole purpose of having adjustable settings. Attach a filter-regulator-lubricator combo before the unit. Without one, you're asking for premature seal failure. Connect the quick-disconnect on the front to whatever kick pad or tooling you need. The stock pad is fine for light work, but for heavier-duty applications I'd recommend swapping to the 2-inch rubber-faced pad. It distributes force better and reduces the chance of marking the workpiece.
Calibration and Force Settings
This is where most people mess up. The dial on top sets the maximum pressure the reservoir can hold before the relief valve opens. Turning it clockwise increases force. The problem is the scale isn't linear, so you'll be guessing a lot until you get a feel for it. My approach has been to start at the lowest setting, test on scrap material, and work up in small increments. A typical bearing press operation needs somewhere between 400 and 800 pounds of force depending on the size. If you're seating a small pin, you might only need 150 pounds. Going too hard is worse than going too soft — one over-pressure event can crack a housing or deform the component you're trying to install.

A Real Problem I Faced and How I Fixed It
About eight months in, I started noticing inconsistent results on a particular batch of aluminum housings. Sometimes the pin would seat properly, other times it would stop short and feel loose. I spent two days chasing the issue — checking air supply, replacing the kick pad, adjusting the force setting. Nothing worked consistently. The problem turned out to be temperature. The shop gets cold in the morning, and the aluminum housings were sitting near a loading dock. The shrinkage difference between the cold housing and the room-temperature pin was enough to throw off the seating depth. Once the housings warmed up, everything worked fine. The fix was basically just letting the parts acclimate for 20 minutes before running them through the line. Stupid-simple once you know it, but nothing in the manual mentions it.
Common Mistakes to Avoid
Don't leave the unit pressurized when you're not using it. The seals are designed for intermittent duty cycles, and keeping constant pressure on them shortens their life significantly. I've seen units go from lasting two years down to six months just from being left on overnight, every night. Another thing: don't use the Super Santa Kicker 2 as a hammer. It's designed for controlled, single-strike applications. If you're bumping it repeatedly against something, you're doing it wrong and you'll break the solenoid valve eventually. I've replaced three of those over the years because someone on the line thought it was okay to use it for alignment adjustments by tapping repeatedly.
Parts and Maintenance
The main maintenance item is the seal kit, which runs about $18 and covers everything inside the piston chamber. I replace these every six to eight months depending on cycle count. The process takes maybe 20 minutes and only requires a couple of O-ring picks and a wrench set. The solenoid valve is the most expensive single part at around $65. It's generally reliable but can fail if you're running dirty air. That's another reason to keep that FRL unit in line. I also keep a spare kick pad and a spare O-ring kit on the shelf because these things tend to fail right when you need them most.
Where It Falls Short
The Super Santa Kicker 2 isn't a universal solution. It struggles with very high-force applications above 1,200 pounds — you'd be better off with a proper hydraulic press in those cases. It also doesn't handle continuous duty well. If your operation requires more than 30 cycles per minute, the unit will overheat and the relief valve will start cycling constantly, which wears it out faster. For light to medium assembly work at low to moderate cycle rates, it's a solid choice. For anything heavier or faster, look elsewhere. There are hydraulic alternatives from manufacturers like Parkson and Sankyo that handle those conditions better, though they cost three to four times as much upfront.
