When a LO / crank machine reaches the set tension the brake release lever pops out and engages the brake to stop all movement of the tensioner assembly. What is being asked is should the brake be engaged (brake lever released) when the machine is not in use.I’m new to crank machines, what do you mean by lock or unlock? Just picked up a used gamma progression ii.
I'm no gamma tech, but it would be logical for tension to be taken off the machine. A torque wrench is something that you always reduce the pound of pressure. Would like to get other insights.Unlock. I asked GammaTech when I bought mine years ago and he specifically said to NOT turn down the tension knob for Gamma machines
You can’t unload everything. The springs are constantly under tension and when the brake release lever is released The springs are still under tension and the brake pads holding the disc on the tensioner assembly is under maximum pressure. The only way to unload everything is to take the tensioner apart and remove the springs. Don’t do that.Everything should be unloaded.
No tension. Pressure, force, load on any part will decrease component life.
Standard eng. practise.
Allowing the tension spring to turn because it has lost pressure can change the linearity of the tensioner. That’s the low and high setting that will be off when checking the tension.sorry guys this is NOT true with the current GAMMA machines. All of the springs are designed to never loose tension or need replacing. You can leave the tension on any setting. you could end up with other problems if you do turn it to zero and the spring isn't pre-loaded. if the spring rotates, even an 1/8 turn, it can affect the calibration (@ low or high lbs.).
There was a zero on the tensioner on my NEOS 1000 &1500. And when I stored the tension head, I set it to zero per Jim Henry. The brakes are spring operated, the OP asked if they should be deployed or against the disc when not in use. The majority of the answers were no, they should not be locked or deployed. There is simply no reason to have the disc pads pushing against the disc which could cause it to go out of round due to the prolonged pressure thereby ruining the unit.There is no xero setting on a lockout tensioner, and the brake are spring operated.
