Default Hi - lift jack

My Hi - lift jack will not cycle down. It will cycle up though. Any suggestions?

oil the piss out of it. Work the pins with a screwdriver. Wipe off the dirt and oil.... repeat about 3 times.

Should be good.

You also need to have weight on it in order to cycle down.

I have found that when you start to encounter this problem it is best to take it apart and clean it. They are very simple to do, no rocket science involved. Don't just clean the pins, the bores are what tend to hold the junk that makes them stick.

Throw it in a dumpster. Fuck those jacks, only time it served me well was to span the doam of my jeep after an accident so the doors would fit again.

this. Get a new one if you can't figure out how to make that one work safely.

they aren't rocket science. Look at it and find why the pins aren't moving properly. Guessing a burr on a pin or cam or hole.

Is that a real hi-lift or a harbor freight hi-lift?

Mine used to stick, needed to be tapped a few times lightly with a hammer to help the pin pop out of the bore.

I really dislike those things, and have done better in most situations with a good bottle jack and base. But there are a few scenarios they are useful (broken suspension parts).

If cleaning it did not work, try banging on it.

Yes, cleaning, tapping, and oiling will generally do the trick. Both pins should be cycling in and out at different points in the stroke. If one isn't then there is your problem, you just need to determine why it isn't moving.

Those things are an absolute death trap but they can be very useful at times, though my use rarely involves lifting a vehicle. Breaking tire beads is what mine gets used for the majority of the time. For an offroad jack it's tough to beat this: http://www.tractorsupply.com/en/stor...%3B-jack-stand
