Yes I must agree with Sean. Being in the constrution industry for many years, once you have passed the Tirfor wire through the winch, leave it there.
I don't know if you have noticed but Tirfor wire is much harder than normal wire and should be treated with repect because if it is damaged in any way it could also damage the Tirfor and never try to use ordinary wire through the Tirfor mechanism as this can cause ordinary wire to slip.
It is not recomended to pass a Tirfor wire through a snatch block because of the construction of the Tirfor wire, If for some reason you should need to pass the wire through a snatch block to increase pulling power, use ordinary wire that conforms with the UTS of the Tirfor wire but do not use bulldog (wire) clamps on the Tirfor wire.
Finally do not extend the cranking handle as there is a sheer pin installed and this will sheer if the Tirfor is over loaded. If a normal sized person cannot crank the handle then the Tirfor is overloaded and double reeving is necessary via a snatch block as previously described. This will double the pulling power of the Tirfor without damaging it. I would strongly recomend that you place the Tirfor to the puller (ie tree or picket) rather than the pullee (ie vehicle). If you reverse this you will find alot of used wire near your vehicle which could be a nusance and be dangerous.
If using a Tirfor for recovery puposes, which I don't, I would also carry two kidney chains and a number of suitably sized shackles
