SuperSplit has a similar issue that operators should be aware of.
SuperSplit is my experience, but it's probably similar on other kinetic models too.
If a piece of wood has knots, crotches, or uneven cut ends and is placed on the beam towards the wedge, there is a possibility the wood will ride up the leading edge of the wedge.
The combined speed and force of the push plate can summersault the wood back towards the flywheels... at head height.
Therefor I've practiced keeping my hand on top of the round, or if a half round, round side down, grasped on the midsection edge, as the split begins. (This is great for multiple splits of a half round.)
The tactile sensation of a round riding up the wedge is then instant. This gives the opposite hand a chance to disengage the rack and pinion by pushing down on the engagement lever. Also the awareness of knots prepares one to respond, and do a mental check of head position, prior to splitting.
More importantly, make it a habit to stand erect along side the beam, and not bent forward towards it. Head, nose, and teeth back.
This summersaulting happens sometimes in seemingly straight grained wood with hidden knots.
I don't have any video of this. But the kinetic energy can flip a 30-35 lb. piece in a blink, landing on the beam, and/or flywheel cover, then goes sideways, or on your toes.
Any one who has run one has most likely experienced this.
If it's your first time using a kinetic, get used to practicing good habits from the git-go and stick with them.
It is a single person use machine.
It cuts the wood vs splitting it.
Like the unit above, they are fun to use and can pile up the splits.
