I have this 6670 and I want to put it in its “as-manufactured” condition. If you look at my photo, 1– the back crank is used for the crane boom through the eyelet. Is that correct?
2– the front crank is used for the stiff leg boom. Is that correct?
3. Should the string (cable) for the crane boom be threaded through the eyelet of the wire stabilizer, and then up to the main pulley, or is there a preferred option.
4- what is the real purpose of the so called “boom lock”?
is there an instruction sheet that answers my questions
