4. Fit a socket wrench to the head of pin (1), then turn it coun-
terclockwise 90° to release the lock of the pin.
5. Push pin (1) out by hand or with a hammer in the direction
of the arrow to remove the teeth (2).
6. Clean the mounting surface, fit new tooth (2) to the
adapter, insert new pin (1), then tighten 90° clockwise with
the socket wrench to lock the pin and complete the installa-
tion.
Turn the tooth upside down and rotate the installation positions.
Such practice allows wear on the teeth to develop evenly, the
lifetime to be extended, and the replacement frequency to be
reduced.
In order to prevent a tooth from a slip-off, insert a pin from
the inside (in the direction indicated with an arrow) for
tooth (4) and (5) on both edges of the bucket.
