Depending on the working conditions, there is danger that the adapter and teeth may break, so select
from the vertical pin teeth and horizontal pin teeth to give teeth that are suitable for the purpose.
METHOD OF SELECTING TEETH
Use of vertical pin tooth
General digging: Digging, loading normal soil, such as
Light-duty digging: Digging, loading loose dry sandy soil
Loading: Loading dry loosened soil
Use of horizontal pin tooth
Heavy-duty digging: Compacting, digging hard soil, soil

mixed with rocks, heavy-duty work such as
l The heavy-duty bucket is a horizontal pin tooth type, so use it for heavy-duty digging.
The standard vertical pin and horizontal pin teeth can be used over a wide range, but we recommend
the following teeth to match the operating conditions.
Long-life teeth
l Jobsites where wear life is demanded, such as when loading hard rocks.
l Jobsites where no penetration is needed, such as when working with crushed rock after blasting or
ripping.
l Jobsites where heavy-duty operations are carried out, such as hitting or pulling up rocks with the
tips of the teeth.
Self-sharpening teeth (horizontal pin type, vertical pin type)
l Jobsites demanding penetration such as digging and loading sandy or clayey soil.
