I've had my Hi-Lift since the late 90s and for when I had a Series Lightweight. The friend that trained me on it told me about the pitfalls and where to go wrong with it as well as before, during and after use to try to understand where the weak points of the plan is, where the vehicle will go, slide or escape to and what would then happen to the jack.
Above all, a strap/strop attached to the top via D-Link so that if all else failed and it dropped in the muck, you could find it afterwards.
Since I stopped having a 4x4 with jackable sections I have used it for other things, including helping a friend brace their back door after they were broken into one night and as a slow winch to get myself, in a 2wd car, out of a ditch I had made the mistake of driving near, and dropping into.
Well, we all make mistakes.
I have seen plenty of these jacks carried on the outside of vehicles, along with ropes and all manner of other 'off road gear'. However, when I get my next 4x4 I am intending to mount it inside the vehicle in its own cradle near the door as well as getting the service kit and sorting that out for it.
Not sure I've dismantled it and rebuilt it, servicing it etc, since I got it but it has had a light dusting of oil every now and again. Stored in a cool dry dark place until I need it.
Last week I saw the use of a wheel lift on a Hi Lift and that was quite excellent, so I am sure I shall have to get that too
Decent looked after recovery gear carried with you and where you know how to use it is always a benefit. Always think before operating recovery gear; where it's going to go, and what happens if it all goes pear shaped... :Wow1:
