5.4 Angle calibration
When using a flat-bottomed bucket, the operator can measure the angle of the bottom of the
bucket. When using a drill/pile attachment, the operator can measure the angle of the attachment.
Angle calibration can be done only if the bucket type is “Flat” or “Drill/Pile” (Figure 21). Bucket type
can be chosen in “Main menu” → “Buckets” → old/new bucket → “Type”.
To carry out the bucket angle calibration, go to “Main menu” and select “Buckets”. Create a new
bucket or choose an existing bucket to be calibrated from the list. Then select “Angle calibration”
from the bucket settings menu.
Carry out the calibration as follows:
1. Drive the machine to a flat surface and rotate the machine until the roll value is close to
zero (until the “Turn!” text changes to “OK!”).
2. Choose calibration orientation. In “Normal” orientation (Figure 21), the bottom of the flat
bucket is aligned horizontally and drill/pile attachment is aligned vertically. In “90 degrees”
orientation (Figure 22), the bottom of the flat bucket is aligned vertically and drill/pile
attachment is aligned horizontally.
3. Press “CALIB”. After this step, the angle calibration is complete. Go back with the “Bucket”
button and save the settings.
After the angle calibration, test the accuracy by placing the bucket on a known surface. The F and
X readings should be consistent with the actual surface. Alternatively, use a spirit level or point
laser for testing the accuracy.
