Salisbury Control box adjustment

[Bazzzerh]

Hi all, I have just purchased a secondhand Powacycle Salisbury via ebay and after fitting a new pedal sensor, it is really good and I am very pleased so far... The guys at Powacycle were extremely helpful in helping me identify the problem and speedy delivery of parts was great so many thanks to them.
I noticed when I had it in bits that there is a small electrical adjuster screw in the control box, the guys at Powacycle new of it but not what it was for..... my first thoughts is it a SPEED adjuster?????? but before I go messing around with it I thought I would ask you guys if anyone knows what it is for....
Many thanks

Should have thought of that!

Hope this helps... it says Hualain Electric, I have googled them and not found anything of help.....

Went for the trial method and found that it is the amount of assist delivered when pedaling. So you can add more when in low gear, makes the bike accelerate quicker! But no difference in top speed.
