On a machine
Put it on a machine

Where it goes
On flat steel that moves with the weight, usually the side of the top plate of the stack. Keep it clear of guide rods, pins, pulleys, cables and the gap between plates.
Before every set
- Check it's firm. If it rocks or slides, take it off and pick another spot.
- Make sure it can't hit anything as the stack moves.
- Never charge it while it's on a machine.
