MAINTENANCE
Installation
1. Remove the dirt on the surface of adaptor
and the inner part of tooth, make the
better contact on the mating part.
2. Push rubber pin lock (3) into the welding
adaptor (4).
Do not let the rubber pin lock stick out
from the welding adaptor surface.
WHEN REQUIRED
3. Install the point (2) onto the welding
adaptor (4).
Insert the point so that the surface behind
the point’s pin hole is aligned with the
surface behind the welding adapter’s pin
hole.
4. Knock out the locking pin (1).
Check that the end surfaces of the locking
pin just knocked out are aligned with the
upper and lower surface of the point. Do
not use the worn locking pin.
The life of the teeth can be lengthened
and the frequency of its replacement can
be reduced by turning it upside down so
that it will wear evenly.
Replace the rubber pin lock and locking
pin at the same time as replacing the
teeth. This makes it possible to prevent
the teeth from falling out

bucket and tighten the side cutter with
nuts.
