I'm new to the site and think the forum is great. I've just had the seals replaced on the drive motors as they were leaking oil into the chain case and now, after leaving the machine for a few days, the front wheels are 100 - 150 mm off the ground! Repairer says it is nothing to do with what he fixed. Is there a relief valve somewhere that could be stuck? Any help appreciated for a new owner.

I assume you lifted the arms and tolted the bucket down or something? The arms have lowered lifting the front wheels up? If so, its normal for the lift arms rams to slowly leak down and they will actually lift the front wheels up if they don't seat fully down and rest on the frame of the machine, its just its balance points that make it do this.
Does that make sense?
