4. Maintenance

This chapter contains procedures for replacing wheels, probes, and wedges for both
conventional ultrasonic and phased array ultrasonic technologies. The probes may
need to be replaced if they malfunction, or if the inspection application has changed.
Depending on operating conditions, the HSMT-Compact scanner parts might need
periodic cleaning.

4.1

Replacing Wheels

This section contains the procedure for changing the wheels once they are too worn.

To avoid injury, use caution when handling the magnetic wheels; the magnetic pull of
the wheels is strong and could cause bodily harm—for example, a finger pinched
between two wheels, or between a wheel and a steel surface.

To replace wheels

1.

Using a flathead screwdriver, remove the screw that secures the wheel to the
frame (see Figure 4-1 on page 30).
