Push out the pin (1) in the direction of arrow with a ham-
mer, and remove the tooth (2).
6.
Clean the mounting face. Fit a new tooth (2) in the adapter.
Push in the pin (1), and rotate it clockwise with a socket
wrench by 90 °. Lock the pin to install it.
REMARK
If the tooth is turned or the mounting position is rotated,
the wear will become uniform. This will extend the service
life of the tooth and reduce the frequency of replacement.
NOTICE
• Replace the pin with new one at the same time as
the tooth is replaced in order to prevent the tooth
from dropping.
• Insert the pins into teeth (4) and (5) on both ends
of the bucket in order to prevent the teeth from
dropping.
