Ski Mojo won’t deactivate

A snowHead

Both legs keeps sticking in the activated position, even when I turn them both off and after straightening my legs (when they stick, I have to turn them back on again, straighten my legs, and turn off again) is there anything I can do myself to resolve?

I thought I may have the rods too long for my height but they also stick when unworn

Can the hinge be lubricated?

Err, they're designed to only unlock with the leg straight, so what you're describing sounds like they're working properly.

Releasing or engaging the catch while they're still bent (whether under tension or not) will do nothing, but once you get the leg straight they will disengage without further action. Similarly I will engage the catch while still sitting on a chairlift and they will just engage when I get the leg straight.

Well, the person's real but it's just a made up name, see?

I’ve edited the post to explain better.. they're not deactivating when I’m straightening my legs.

They also don’t deactivate when I try whilst not being worn?

You need to Login to know who's really who.

@FrostyFish, I've wien a mojo for 10 years, I can't visualise what you mean.

I stand straight, engage the mojo by flicking the switch down, put skis on. I only disengage them when taking skis off so unclip out of skis, straight legs flick switch up.

Is that what you are doing and its not working?

Email Martin at ski mojo to ask?

Anyway, snowHeads is much more fun if you do.

It's still not clear what exactly is happening, but I don't think lubrication is the answer. There is nowhere to lubricate them anyway.

Here's what min do when not being worn, try to find a point where yours are not doing the same.

They sit in the straight position, the catch is in the up position, they can bend easily without the spring being engaged.
Move the catch into the down, i.e. engaged position, there should a little resistance to this as it pulls the spring mechanism slightly, then the catch will hold at 90degrees to its original position. At this stage, bend the knee part and you should encounter mounting resistance as the spring is tightened.

Now, test 1. Let the mojo come straight, move the catch back into the up position, it should click down and the arms should then be free to bend with no resistance.
If that works OK then test 2. Reengage the catch and bend the mojo again, now this time while it is still bent move the catch into the up, unlocked, position. It should be very loose at this stage.
Move the arms back into the straight position. Once there the catch should audibly click into place and no longer be loose, and you should be able to move the arms freely again.

If this is not happening then yes, you have a problem. Is the catch, err, catching at all? There are two split pins, one visible on the outside and one being revealed on the catch itself as you move it. Are they both fully in position? I have known them to work loose on an older model my wife used to have quite a few years ago, and if so that could be causing your problem and may be able to be resolved by just pushing them firmly back into a more flush position.

Otherwise I'm not sure what to suggest, but customer service has always been fantastic and I hope will still be so even though Martin's now sold the company to a French owner, so if you bought it at a shop take it back there or if not get in touch with the supplier, and I'm sure they'll get it sorted for you.

Edit: ISTR having spare split-pins at one point, not sure if they came with the device in the first place, but if you have one then you could try removing the original and looking at the mechanism in case of damage. (Don't do this if you dont have a spare pin, they're quite easy to damage when removing). If both sides are behaving the same then this is perhaps less likely though.

You'll need to Register first of course.

@FrostyFish, there’s actually another adjustment- a cable adjustment hidden in the lower part of the spring unit just below the hinge. You’ll need to move the bottom part of the neoprene knee support out of the way and there’s a small cavity with a small metal wheel and the end of a threaded bolt. Rotate the wheel a little at a time - can’t remember which direction- and this adjusts the cable length which in turn adjusts the mojo ‘bite point’. Good luck.

Then you can post your own questions or snow reports...

@RUGBY PETER, That's what you use to adjust the pre-load on the spring, for more or less resistance/support. When the mojo is straight it should make no difference at all the 'bite point'. If it does then there is something seriously nadgered inside and the whole unit needs replacing. And incredibly unlikely to be doing the same thing on both legs.

After all it is free

@Chaletbeauroc, No @RUGBY PETER, is taking about the barrel nut in the lower section of the mojo that adjust the length of the cable not the preload on the spring. It is prevented from undoing by a tape across it and really isn’t touched by the user unless you are replacing the cable or spring. Yes, I’ve had the cable snap and had to use this ajuster when I replaced the cable.

Back to the op. First of check that you have it fitted correctly. Then examine how it works off the leg. Have a look at the YouTube video on how to replace the cable. It shows the detail of how the mojo is constructed. Pay attention to the bit about the locking mechanism. You may need to replace them. Spares are readily available for the mojo so you shouldn’t have to replace the whole unit.

Help!!
