Adjusting perforated blades
When adjusting perforated blades, the bolts can be removed by holding the bolt head with locking pliers and loosening
the locking nut behind the blade. Also, when tightening, the bolt head will need to be held to enable the nut to be
tightened. M20 washer is added under the bolt for getting a better grip on it (picture 11).
The bolts are removed, and the blade lowered until a hole on the blade frame can be seen again. The bolts are attached
now to the holes next to the ones they were attached to before (picture 12). This enables the blade to be lowered
appropriately (picture 13).
