Place the bolt (H) that holds the lock nut (I), along with a spring washer and nut, only
on the outer side of the gangs.
Use the wrenches to tighten the gangs as follows:
1) Place one of the wrenches in the outer side of the gangs (locked side), supporting
it on the ground. (As shown on the next page).
2) On the inner side, use the other wrench and tighten the gangs to get maximum
torque.
3) To tighten the gangs, underpin them using a piece of wood or another object, thus
preventing them from moving. (As shown on the next page).
Lastly, put the bolt (H-1) and position the lock nut (I-1), fastening with a spring washer
and nut.
