Installation

PERFORMANCE ORDER
1. If you decided to replace the generator, then be convinced that new (or repaired) the generator in accuracy corresponds to replaced. Pay attention to conclusions – their number, the sizes and a relative positioning has to be same, as on the replaced unit. At last, check marking. Marking has to be or is stamped on the case, or printed on a label and pasted on the case. Make sure that numbers on the new and replaced units coincide.
2. On many new (or repaired) generators there are no pulleys therefore it is necessary to rearrange a pulley from the replaced unit.
3. Installation is carried out upside-down. Adjust a belt tension.
