Figure 8.1 Cab rotation sensor installation
1.1. Check the installation of the sensor bracket.
2. Apply the provided Loctite to the M16 bolts (4).
3. Loosely bolt the sensor to the mounting bracket using the M16 bolts (4) and
the washers (5) provided. The sensor must be installed so that:
the arrow on top of the sensor (1) points towards the front of the machine
the notches on the bottom plate of the sensor (2) are on the forward edge
of the bottom plate
4. Adjust the sensor so that the arrow (1) is parallel to the centerline of the
excavator body.
ATTENTION — If the body pitch/roll sensor feature of the HS410 heading sensor is
used, the alignment of the sensor with the centerline of the machine is critical.
