Hello There.
I would think that if you get in touch with ALKO, they might be able to get you an instruction manual. Lucky for you that the company is still trading!
As to the depth gauge, the further it's down to the ground, the shallower the depth of tilling, likewise, bring it up out of the soil, and the machine digs deeper.
A friend of mine used to have one, he reckoned that with the 3.5hp engine, it was better to dig over the ground a few times, going a bit deeper each time, mind you, he lived in Tolworth and the soil was quite heavy clay just below the surface.
We don't, as Ice said, allow buying and selling on this forum, it's a pity we haven't got a copy of the manual on pdf yet, or you could have down-loaded one for nowt............
