The rubber of the rubber pin lock is torn, and the steel balls may
come out.
The steel balls are buried when they are pressed by hand.
4. Clean the surface of adapter (4) and remove the soil with a knife.
5. Use your hand or a hammer to push rubber pin lock (3) into the
hole of the adapter.
When doing this, be careful that the rubber pin lock does not fly
out from the adapter surface.
6. Clean the inside of teeth (1), then install it to adapter (4). If there is mud affixed to it or if there are protrusions,
the teeth will not enter the adapter properly, and there will not be proper contact at the mating portion.
7. Fit tooth (1) to adapter (4), and confirm that when the pointer is
pressed strongly, the rear face of the hole for the pin of the
teeth is at the same level as the rear face of the hole for the pin
of the adapter.
If the rear face of the hole for the pin of teeth (1) is protruding
to the front from the rear face of the pin hole for adapter (4), do
not try to knock the pin in.
There is something preventing teeth (1) from entering adapter
(4) fully, so remove the obstruction. When teeth (1) enters
adapter (4) fully, knock in lock pin (2).
