During a hard pull or multiple pulls the cooldown is probably more important. That said, I am unfamiliar with the design of your winch specifically and if the brake drags during use it will heat regardless of the load and require cooldown. Probably best to follow the manufacturers recommendations. That said, I can not remember waiting fifteen minutes everytime I pulled for a minute? If you think it is getting hot, it probably is. I do think about it and try to be nice to mine
Now that you are all set, I hope you have gathered some extras for winching. I carry two 12"x12"x4" bags with straps, clevis, snatch block and a couple squares of belting to protect the rope.
If you are running the wire rope first on your priority list should be some good heavy gloves , a cable hook and an "energy absorber". That energy absorber is a heavy blanket to drape over the cable to grab the energy released during a failure. I have a torn up old heavy coat that did just that. The Puller jammed the clutch and broke the cable. My coat was enough to grab the cable and keep it from going through the window of the rig being pulled. Those guys really learned the importance. My coat got tore up, but it was worth it. Put that "cable blanket" on the top of your list if you don't have one.
Think about upgrading to a synthetic rope some day. Lighter is nice on a cradle mount winch. Safer, no burrs or stored energy to worry about. Also field repairable. Quick easy "weave" poke and slip to get your rope back in service.
Almost makes ya want to find someone stuck now...not
