●
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 other 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 tooth is
pressed strongly, the rear face of the hole for the pin of the
tooth (1) 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 tooth (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 tooth (1) from entering adapter
(4) fully, so remove the obstruction. When tooth (1) enters
adapter (4) fully, knock in lock pin (2).

steel balls come out easily
